Abstract
A new-type platform-type grinder for lining plate features that the grinding surface of lining plate is composed of one or more platforms with different heights and transition surfaces. It is divided into platform type ladder, single wave and angle spiral lining board. When the wave-shaped height difference is equal, the platform is a powerful measure for increasing the radial relative rubbing distance between adjacent grinding bodies in the lower sliding grinding body group; the straight edge part is the main method for increasing the rubbing frequency, and the outward shift is the main means for expanding the volume. The multiplied radial twisting distance and times accelerate the crushing and grinding of large and small materials clamped in the grinding medium. Compared with the existing mill, the machine-hour yield is improved by more than 10-35%, and the energy-saving and ball-saving effects are remarkable.
Description
The grinding machine that is to use the specific waveforms liner plate that the present invention relates to.
Autogenous tumbling mill comes out 100 for many years, has become the quite general equipment of a kind of use, and only China just has tens thousand of.For protection cylindrical shell and transmission energy, generally all set up liner plate on the grinding mill barrel inwall.A large amount of forms appearred in its shell liner, and the principal mode of the shell liner of grinding machine use both at home and abroad has following several at present: monophasic waveform liner plate, double wave shape liner plate, rudder for ship shape liner plate, stairstepping liner plate, small ripple glaze lining board of globe, plain weave liner plate etc.Be used for the single ripple liner plate of being mainly of metallurgical system (Fig. 1), double wave liner plate (Fig. 2) and rudder for ship shape liner plate (as Fig. 3); What be used for cement system is mainly ladder lining board (as Fig. 4), small ripple glaze lining board of globe (as Fig. 5) and plain weave liner plate.Also have high ripple liner plate (as Fig. 6), fin liner plate, press strip liner plate, classifying lining board, trench liner, spiral angular liner in addition and be applicable to various press strip liner plates that rubber is used or the like.
Spiral angular liner (be called for short angle lining) is after early sixties Austria Einger-Wagger Biro company releases first and tests, and is once energy-conservation and to improve many advantages such as grinding efficiency fashionable for a time with it, launched to develop widely and test in worldwide.According to reports, by nineteen eighty-two, having 50 grinding machines to reequip the angle lining abroad approximately, is that level and smooth angle, garden square spiral liner plate is the most general with abradant surface wherein, and the abradant surface that also has is for adding taper classification type on smooth surface.Though the angle of these types lining grinding machine result of use can save ball, mainly be suitable for secondary grinding (or cement grinding mill two storehouses, three storehouses).Domestic angle lining research is started in the seventies, the result of the test of units such as Cangzhou Area cement plant, cement plant, Handan shows that being four square spiral angular liners of angle, garden can only be used for cement grinding mill two, three storehouses, if a storehouse is also with this angle lining, treating capacity just descends significantly, even use in two, three storehouses, effect is very unobvious yet.For this reason, China has developed the hole enlargement mill that the grinding machine external diameter is enlarged again, dwindles the more problem that causes that treating capacity descends to solve because of established angle lining back dischargeable capacity, has at present domesticly manufactured experimently nearly ten.Because of the angle is lined with energy-saving effect, the grinding machine power output is basic identical before and after the hole enlargement.According to investigations, through this improvement, domestic result of the test about the cement plant is: the hole enlargement mill of established angle lining is compared with the non-hole enlargement mill that common liner plate is installed, and does not still have clear superiority, and tell the piece phenomenon when raw meal particle size is bigger than normal.In addition, some metallic ores select factory also to carry out angle lining test, all abandon because of no remarkable result midway.We think these angles lining grinding effects not good reasons and are that angle lining abradant surface Waveform Design is unreasonable to be caused.
In order to overcome this deficiency, we have proposed the improvement way of diagonal angle lining in 93110401.7 patents of invention.Design concept at that time is to strengthen the radial motion distance of milling medium in grinding machine significantly, thereby just the unit-hour output of grinding machine obtains suitable raising.Along with going deep into of research, we have obtained flatbed ladder lining board utility model patent (ZL95236580.4) and had proposed platform-type lining plate grinding machine patent application (96118083.8) (hereinafter to be referred as 96 type platform grinding machines) in 96 years again in 95 years, and in August, 95 always * * cement plant, county Φ opens on the flowing water mud grinding machine for 1.83 * 6.4 meters and carries out pilot production.Pilot production more than 2 years proves, uses above-mentioned technology, and under the situation that power consumption does not increase, unit-hour output has tangible increase, and maximum data are that volume increase is more than 40%.This statement of facts, this technology are effectively, prove that the main design that we produce this invention is correct.This design is exactly the starting point that we propose in 96 type platform lining board grinders:
In flatbed ladder lining and flatbed list ripple lining grinding machine, our starting point is: in process of lapping, the abrasive media that clips material is in garden curvilinear motion district, because gravity and action of centrifugal force, along the liner plate working surface to lower slider, owing to the distance of each point on the liner plate working surface to the grinding mill barrel center line do not wait, just brought up the adjacent abrasive media relative motion radially of gliding again along the liner plate surface.The relative motion of abrasive media is radially layer by layer to the grinding machine internal delivery on the liner plate surface, thereby causes the abrasive media continuously rubbing back and forth radially in the curvilinear motion district, whole garden.The big or small material that this rubbing effect will be clipped in the medium is pulverized and grinding.If distance of rubbing is bigger back and forth for this, then the effect of grinding and pulverizing just better.Second starting point of the present invention is: under the same distance of rubbing back and forth, if the rubbing frequency is higher, then grinding and crushing effect are better.Think after our research angle lining straight flange have be beneficial to abrasive media and material to lower slider (promptly increasing the rubbing frequency).In brief, say " rubbing frequency ".Except increasing the rubbing with 96 type platform grinding machines, go back otherwise and reach the purpose of increase " rubbing "? the purpose of this invention is to provide novel platform-type lining plate grinding machine, with as 96 type platform grinding machines a kind of being replenished and perfect, perfect so that the present invention more becomes.
Platform-type lining plate grinding machine of the present invention still is divided into flatbed ladder lining board grinding machine, flatbed monophasic waveform lining board grinder, three kinds of main types of flatbed angular screw lining board grinder.Its architectural feature division is as follows.
(1) flatbed ladder lining board grinding machine is the ladder lining board that replaces former usefulness with the flatbed ladder lining board, plain weave liner plate and small ripple glaze lining board of globe.Six faces that three pairs of combinatorial surfaces that its structure is made up of per two obverses form are formed, and each architectural feature to combinatorial surface is respectively: (1) abradant surface and installed surface.Abradant surface is towards the grinding machine center of rotation directly and grinding charge material and the contacted working face of medium, and its corresponding surface then is opposing with it and be along cylindrical shell garden Zhou Fangxiang, correspond to installed surface and form to several transition faces are alternate to several platforms that highly do not wait and by one to each cascaded surface of corrugated that several a head taller low ladder is formed by one towards the installed surface abradant surface of grinding mill barrel wall; The intersection connects with the garden arc.Decide on its service condition is different the length of platform, gradient and position.Gradient can just can be born, and also can be zero, when being zero and installed surface almost equidistant.When a liner plate working face only has a ladder and platform gradient to be zero, promptly be that the platform ladder lining board described in the 96 type platform grinding machines is same.(2) two sides of liner plate be above-mentioned abradant surface of a pair of maintenance and installed surface shape and along identical two planes of shape that the cylindrical shell length direction stretches.(3) end face of liner plate is that end line by above-mentioned abradant surface and installed surface, two sides is along formed two planes of cylindrical shell length direction.
It is single platform single-order step ladder liner plate, two platform single-order ladder type ladder lining board, multi-platform single-order ladder type ladder lining board and single platform pair notch cuttype ladder lining boards or the like that the flatbed ladder lining board can be divided into according to the quantity of grinding the working face upper mounting plate.
(2) flatbed list ripple lining board grinder is the single ripple, double wave, high ripple liner plate that replace the former usefulness of grinding machine with flatbed monophasic waveform liner plate to reach the purpose that improves output, energy-conservation, joint ball.Every block of single ripple liner plate is two half-waves that the boundary can be divided into symmetry with its line of symmetry, takes these two half-waves to compare with existing ladder lining board, can think that they all are the distortion of ladder lining board.Its difference is: (1) is ground the cross section of working face and is formed the curve difference.The ladder lining is generally by garden curve or garden curve and rectilinear(-al), and single ripple liner plate is made up of several sections tangent gardens substantially; (2) width difference.The more single ripple liner plate of the width of ladder lining board is wide; (3) type of attachment difference.Single ripple liner plate is formed protruding and recessed single ripple by two half-waves by high-high and low-low form of joining, and ladder lining board then is just to join to forming sawtooth liner plate working surface.If ladder lining board is also formed the shell liner working face by high-high and low-low joining, it also is the monophasic waveform liner plate, but the size of ripple, there were significant differences for shape.In a word, single ripple liner plate is out of shape the liner plate of forming by two ladder lining boards.In view of the above, flatbed list ripple liner plate is made up of two identical flatbed ladder lining boards.When these two flatbed ladder lining boards connect high head-height head and join, form protruding flatbed list ripple liner plate, when joining, form recessed flatbed list ripple liner plate by bow-bowing.Its primary structure of flatbed list ripple liner plate also is made up of six per two corresponding faces as the flatbed ladder lining board, and difference is an abradant surface.The feature of grinding working face is: (1) is undertaken by the design method of flatbed ladder lining board for the design of the little semi-simple ripple working face of width.Its feature is as follows; Abradant surface is along cylindrical shell garden Zhou Fangxiang, corresponds to installed surface by one to the corrugated that several a head taller low cascaded surface is formed, and each ladder corrugated is made up of platform and transition face, and the intersection connects with the garden arc; Land lengths is decided on its service condition difference, and the corresponding part with cylinder inner surface of platform is tending towards parallel or certain angle is arranged, and the platform working face also can be plane, inclined-plane, the corrugated of nick, dimpling; The transition face adjacent with platform is high and low two different inclination corrugateds; Again the obvious angle that forms because of two transition faces inner surfaces corresponding with it thus make each ladder abradant surface be one a head taller low domatic, transition face can be tapered plane, also can be convex or concave Iy curved.(2) (the angle lining such as 3 meters grinding machines of Φ can be considered by four single wave components for the big semi-simple ripple of width, its single wave width is calculated by cylinder internal diameter and is at least 1500mm, and calculating by angle lining design lines also has the 1300mm wide) the design of grinding working face should carry out structural design by the method for multi-platform single or multistage ladder type ladder lining board.Be that the alternate composition with several transition faces of several platforms has zero abradant surface to several ladders, the intersection of platform and transition face is connected with the garden arc.(3) actual the applying for ease of inventing, the present invention only carries out design improvement to the waviness of the surface of every block of liner plate, hoisting depth (being the poor of highs and lows on the working face) slight change, other size is constant basically, this help the user do not increase the investment just can use the present invention.
(3) flatbed angle spiral grinding machine is flatbed ladder and/or flatbed monophasic waveform liner plate and spiral angular liner are combined as a whole and form flatbed angle spiral shell liner plate, now forms with liner plate replacing.The angle lining structure scheme of angle provided by the invention lining grinding machine is:
1, some liner plates are installed on the column-shaped barrel inner surface of grinding machine garden, wherein every several liner plates are combined into lining unit, an angle, and lining unit, some angles arranging situation in cylindrical shell is: along the cylindrical shell length direction, every one section cylindrical shell distance, the setting angle of its unit is wrong mutually.Identical in the angle of cylindrical shell garden Zhou Fangxiang lining unit number with the angle number of angle lining.
2, six faces of every block of liner plate in the lining unit, above-mentioned novel angle are divided into three opposites.The situation on each opposite is: a pair of abradant surface towards the grinding machine center of rotation and opposing and towards the installed surface of grinding mill barrel with abradant surface, a pair of be keep above-mentioned abradant surface with the shape of installed surface along the identical two sides of shape that the cylindrical shell length direction stretches, another is to being the both ends of the surface along cylindrical shell length direction connection abradant surface, installed surface and side.From the cylindrical shell cross section, the installed surface that lining unit, said angle is formed forms angle, garden polygon on week in whole cylindrical shell garden, and the garden camber line and the cylindrical shell at Qi Yuan angle are tangent, and also the straight line that is connected with the camber line two ends is tangent or crossing.Angle lining part between the center of adjacent two sections straight lines is above-mentioned lining unit, an angle.For the convenience of describing also can be considered as lining unit, an angle every straight line with at garden arc preceding or subsequently.
3, according to the moving veer (as shown by arrows) of grinding machine, lining unit, said angle is divided into two part garden arc parts and straight line portion along cylinder inboard wall.Straight line portion can only be that straight line also may be that straight line adds part garden arc.Garden arc part is a design basis with the cylindrical shell garden, and the fluctuating difference in height with reference to former lining board of grinder is designed to flatbed list ripple liner plate or flatbed ladder lining board measure-alike or inequality more than 1.For straight line portion, method for designing is: (a) selection of design basis line: be to be the design basis line with the cylindrical shell garden in principle.(b) shape of grinding working face is a benchmark with above datum line, and every block of liner plate can be designed to the flatbed ladder lining board that various sizes do not wait; Also can be designed to the polylith liner plate and form multi-platform single ripple liner plate of one; Also can be with flatbed ladder lining board and the staggered use of flatbed list ripple liner plate; But left-right symmetry also can be asymmetric; Various flatbed list ripple liner plates (protruding is recessed) and flatbed ladder lining board are all available.In a word, under the prerequisite that takes into full account the liner plate life-span, design rubbing apart from the liner plate maximum, that frequency is the highest.
4, the design of the grinding working surface of flatbed angle lining will be carried out according to the size of using abrasive media.
The drawing explanation: Fig. 1～Fig. 6 is that the part lining board of grinder is now used technology wave-shaped cross-section figure, Fig. 7～Figure 13 is the cross-sectional view of grinding mill barrel liner plate of the present invention and grinding mill barrel part, and be described respectively below in conjunction with embodiment: Fig. 7 and Fig. 8 are flatbed ladder lining board wave-shaped cross-section figure of the present invention.Fig. 9 is protruding couple of platform list ripple liner plate wave-shaped cross-section figure of the present invention, and Figure 10 is flatbed rudder for ship shape ladder lining board wave-shaped cross-section figure, and Figure 11 to Figure 13 is the wave-shaped cross-section figure of part flatbed spiral angular liner of the present invention.Double dot dash line is represented former liner plate cross section general shape or is angle lining formation line among the figure, and arrow is represented rotation direction.
The embodiment 1 existing just waveform cross section of Fig. 7 describes.AC ' E ' FGHI is the original-shape of former liner plate.AC ' E ' F double dotted line among the figure has marked the situation of former grinding working face.GHI is the installed surface towards the grinding mill barrel inwall, is the garden arcuation, and the radius of its garden arc and length are identical with the garden arc radius and the length of the liner plate that will substitute.AI, FG represent two end faces of liner plate, and the visual former liner plate size of the height of Al, FG is determined.Two groups of abradant surfaces representing the flatbed ladder lining board that designs by 96 type platform grinding machines according to the different ABCDEF of the condition of using and AB ' C ' D ' E ' F respectively.The ABCDEF abradant surface has three platform AB, CD and EF and two transition face BC and DE.They fuse the platform end.The relevant place with transition of platform connects with the garden arc.AB, CD, EF section are substantially parallel with the corresponding part in the arc of GHI garden.BC, DE and GHI garden arc have formed certain angle.AB ' C ' D ' E ' F ' F is similar to the situation of ABCDEF abradant surface, three all substantially parallel garden of platform arc GHI, and three transition faces are all formed certain angle with GHI." KMNPQ represents two groups of grinding working faces by the present invention's design respectively for ABC among the figure " D " EF and ABC.ABC " D " EF abradant surface grinds main different places with ABVDEF, be according to 96 type Flat grinder patent applications, three platform AB, CD and EF are parallel to installed surface IHG basically, and according to the present invention, these three platforms are not necessarily wanted parallel IHG, grind C " D " platform in the working face with regard to obvious not parallel IHG such as ABC " D " EF, do like this and more help design, more help when increasing rubbing, damaging medium along grinding flowing of working face not manyly, replenished the deficiency of 96 type platform grinding machine patent applications.We can say that also it is to realize one of way that increases " rubbing ".ABC " KMNPQ sign grinding working face by two ladder ABC " K and MNPQ form, and each ladder all has two platforms, a transition face, and the parallel installed surface IBG of AB, PQ cardinal principle wherein, " K, MN's platform C then form an angle with IH6.This design also is a kind of way that increases rubbing.
The embodiment 2 existing just waveform cross sections of Fig. 8 describe.Fig. 8 is the flatbed ladder lining board that is used for replacing the small ripple glaze lining board of globe of Fig. 5 to use.Because used medium is less, has a grinding working face to several ladders so be equipped with on a liner plate, the concrete condition of design is identical with embodiment 1.Now only just grind working face and do some explanations, A " D " H ' D ' working face is made up of all two identical flatbed staircase waveforms and is formed by platform is alternate with transition face, from the figure as can be seen, each corrugated is all formed by platform is alternate with transition face, but have plenty of parallel with installed surface B ' J ' C ' substantially, as E " D " and E ' D ', the platform that has and B ' J ' C ' are not parallel, as A " I ", G " F ", H ' I ', G ' F '." CDFGIJH grinds working face and is made up of four identical flatbed group shapes A, and as can be seen, each corrugated all is a platform and an inclined-plane composition from the figure.
The embodiment 3 existing just waveform cross sections of Fig. 9 describe.Double dot dash line AKLDMNGHIJ is the original-shape of former liner plate abradant surface.AJ and GH are two end faces, and JIH is the installed surface towards the grinding mill barrel inwall, and these sizes still maintain the original state.The ABCDEF6 line represents that it is made up of two flatbed ladder abradant surface ABCD and DEFG by single popin bench-type liner plate of 96 type platform grinding machine patent applications design among the figure.BC section among the figure and EF section are that this platform of the said platform of 96 type platform-type lining plate grinding machines equates substantially with the distance of JIH.AB section, FG section, CD section, DE section (or meaning CDE section) then are respectively four (or three) transition faces.AB ' CDEF ' G among the figure is by the grinding work of the present invention design, its different platform B ' C that are with ABCDEF6, and EF ' is not equidistant with the distance of JIH, it has replenished the deficiency of 96 type platform grinding machine patent applications.That is to say flat surface not necessarily will with installed surface (cylinder inboard wall) plane, also can produce same effect, then more help sometimes the design and rubbing.
The embodiment 4 existing just waveform cross sections of Figure 10 describe.ABC ' D ' EF6HIJK is the original-shape of rudder for ship shape liner plate cross section, and HIJ is the installed surface towards the grinding mill barrel inwall, and AK, GH are two end faces, and these sizes still maintain the original state.The emphasis of invention is on working face ABC ' D ' EF.Rudder for ship shape liner plate generally is used for metallurgical system, and the active length of every liner plate garden Zhou Fangxiang generally is about 1.5 times of ladder lining board, and the ball milling condition of work of metallurgical system is more than cement system abominable (being that wear liner is several times of cement wear liner) in addition.Shape and original shape that the ABCDEF that designs by method for designing of the present invention grinds working face are similar.Wherein AB, CD, EF can be considered platform, and BC, DE can be considered transition face, and the intersection, two sides connects with the garden arc.Platform AB is parallel with installed surface JIH substantially, and platform CD, EF then become a tangible angle with installed surface, and its incline direction also has nothing in common with each other.Just be difficult to design such shape and come and design by 96 type platform grinding machine patent applications (platform must parallel JIH).For the rudder for ship shape liner plate of Φ 3.2 grinding machines, in case after changing working face into ABCDEF by ABC ' D ' EF, when replenishing Φ 100 balls, radially rubbing has increased by three times." LMD ' EF has represented that the another kind by the present invention's design promotes the shape of the barreling working face of rubbing to A ' B ' C among the figure; " L and MD ' EF ' form by two ladder corrugated A ' B ' C for it, the obvious not parallel JIH of platform EF is formed by two platforms and a transition face in each corrugated.
