Abstract
The utility model provides a novel platform type ladder welt that mill was used which characterized in that: the working surface in contact with the grinding material and the grinding medium is a wave-shaped surface consisting of a platform and two transition surfaces. The platform type grinding surface can intensify the relative radial rubbing between the grinding media by times, so that the ground materials mixed in the grinding media are crushed and ground in an accelerated way. Compared with the traditional stepped lining plate, the yield of the mill is improved by more than 20 percent, and the stepped lining plate has the advantages of ball saving, energy saving, safe installation of the lining plate, easy disassembly and the like, and is suitable for utilization and transformation of the original mill.
Description
The utility model relates to the liner plate of the specific waveforms that grinding machine uses.
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.Grinding machine a large amount of forms occurred with 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 etc.Be used for the single ripple liner plate of being mainly of metallurgical system, two plate liner plate and rudder for ship shape liner plate; What be used for cement system is mainly ladder lining board and small ripple glaze lining board of globe.In addition also have various press strip liner plates that high ripple liner plate, fin liner plate, flat ripple liner plate, press strip liner plate, spiral angular liner, classifying lining board, trench liner and suitable what rubber uses or the like.
In grinding process, the milling medium that clips material is in the bent motor area of circle, because the effect of gravity, along the liner plate working surface to lower slider, because each point does not wait to the distance of grinding mill barrel center line on the liner plate working surface, just caused the adjacent milling medium relative motion radially of gliding along the liner plate surface.In the relative motion of the lip-deep milling medium of liner plate radially layer by layer to the grinding machine internal delivery, thereby the continuously rubbing back and forth radially of the milling medium in the whole circular curve motor area.The big or small material that this rubbing effect will be clipped in the medium carries out powder essence and grinding.The distance of rubbing is big more and number of times is many more back and forth as this, and then the effect of grinding and powder essence just better.
At present general a kind of ladder lining board is as shown in Figure 1 in the cement industry.Generally form with the working face that the grinding material contacts with milling medium, and arc surface is generally low one by an arc surface and one section inclined-plane.We once carried out test and calculating to the ladder lining board of many forms.In the process that the grinding charge material glides, certain radially rubbing is arranged, but because the rubbing distance is little, grinding effect is undesirable.
The purpose of this utility model is: the novel shell liner that provides a kind of grinding machine to use---flatbed ladder lining board.The relative rubbing that it makes the milling medium in curvilinear motion district, cylindrical shell garden is strengthened exponentially.With and mill output is significantly improved, and energy-conservation and the joint ball.
For achieving the above object, the structure of the flatbed ladder lining board used of grinding mill barrel provided by the utility model is made up of six faces.These six faces are included is three pairs of combinatorial surfaces that per two obverses 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 towards the installed surface of grinding mill barrel wall; Abradant surface is along the cylindrical shell length direction, corresponds to installed surface and be an a head taller low corrugated, and whole corrugated is made up of platform and transition face; Platform is at the middle part of whole abradant surface, and land lengths is decided on its service condition difference, and the corresponding part with cylinder inner surface of platform shape is tending towards parallel, and also visual its length is the corrugated of nick, dimpling; The transition face adjacent with platform is high and low two different corrugateds, the angle that transition face and its corresponding cylinder inner surface form is greater than the angle of platform relative cylinder inner surface formation with it, so the corrugated is what tilt, the corner dimension difference that forms because of the corresponding with it inner surfaces of two corresponding transition faces again, so make whole abradant surface be one a head taller low domatic, these two transition faces can be tapered plane, also can be convex or concave Iy curved; Platform is that arc surface is connected with the intersection of transition face.
＜2〉two sides of liner plate are a pair ofly to stretch between above-mentioned abradant surface and installed surface, again 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 garden Zhou Fangxiang.
Adopt the utility model in order to help the user, the liner plate that the basic and former grinding machine of liner plate size of said structure uses is measure-alike.
Accompanying drawing 2 is a waveform sectional view of the present utility model.
The ladder lining board that accompanying drawing 3 is used for former grinding machine and transform waveform sectional view of the present utility model as.
Embodiment: existing waveform cross section with regard to accompanying drawing 2 describes.EF is the installed surface towards the grinding mill barrel inwall in the accompanying drawing 2, is the garden arcuation, and the radius of its circular arc and length are identical with the arc radius and the length of the liner plate that will substitute.AF, DE represent two end faces of liner plate, the visual former liner plate size of the height of AF, DE is determined, for towards grinding mill barrel center abradant surface, wherein AD middle part BC is one section plane, it with EF in relative partly parallel, promptly parallel with the GH section in the EF arc, adjacent part with plane BC is respectively the concave surface that is connected between A, the B
Connect the convex surface between the CD point
With
Formed certain included angle with FG, HE.
As shown in Figure 3, compare with the ladder lining board (the grinding cross section is ABCDEF) that ladder lining board of the present utility model (the grinding cross section is ABGDHLK) and former grinding machine are used, radially rubbing is increased to original three times relatively.Have following advantage when being used for grinding machine according to flatbed ladder lining board of the present utility model:
1. compare with existing ladder lining board, when mill running, milling medium in lifting and the downslide process in radially back and forth rubbing increase exponentially, the big or small material that is clipped in the medium is pulverized and the flour mill meeting fully, with and the output of grinding machine is improved significantly.The unit grinding efficiency can improve more than 20%.Bring significantly per unit area yield joint ball, energy-saving effect with amount therewith.
2. waveform of the present utility model can fully be taken into account the size variation of ball, thereby each section, each storehouse in the grinding machine operation are not needed clear ball in principle.
3. the utility model in use can be protected the existence of liner plate platform chronically, thereby mill output is stable basically.
4. help removing and installing of liner plate, alleviate liner plate worker's labour intensity, save the time of changing liner plate.
