Abstract
A star-shaped graded disintegrating mill of the utility model comprises a cylinder body and a driving mechanism which drives the cylinder body to rotate, a cylinder body supporting mechanism, a material scraping board and a material guiding board which are arranged in the cylinder body, a material inlet pipe and a material outlet pipe which are arranged on the cylinder body, and a grinding roller group composed by a plurality of grinding rollers and grinding roller supporting fixation devices which are arranged in the cylinder body, wherein grinding roller group comprises a central roller and two or more edge rollers which surround the central roller. The utility model has the unique grinding roller group structure which comprises the central roller and edge rollers, thereby materials of different sizes can be grinded in different sections gradually through the material scraping board and the material guiding board respectively, energy can be utilized more reasonably and effectively with more extraordinary energy saving effect than normal cylinder-roller mills, and meanwhile, the rotating speed of the cylinder body can be adjusted on the line or off the line, performance indexes of the equipment is more stable, and the utility model has small cubage, lightness, and lower manufacturing and maintenance cost.
Description
(1) technical field: the utility model belongs to grinding machine equipment, is specifically related to a kind of star graded crushing mill that can be used for various materials fragmentation and grinding.
(2) background technology: at present external roller mill HOROMILL for sleeping in, cemax and domestic cartridge type roller mill, hold and put wheel and mill etc., its structure substantially all is the some rollers of device in the cylindrical shell, and by the hydraulic means pressurization, and the material that thickness the varies in size disposable instantaneous high pressure that mixes is pulverized; And the rotating speed of existing tube roll grinding cylinder is fixing nonadjustable; Because the said structure characteristics must cause that the milling equipment rotating speed is slow, volume is big and be heavy, it is higher to make maintenance cost.
(3) summary of the invention: the purpose of this utility model is exactly that the structure of existing similar grinding machine is improved, propose a kind ofly can carry out online or the off-line adjustment according to the physical and chemical parameter of material and the fineness requirement of finished product, and the different material of granular size is carried out subregion grind, volume is little, the star graded crushing mill that manufacturing and maintenance cost are low.
Star graded crushing mill comprises cylindrical shell and drives the driving mechanism that cylindrical shell rotates; Cylinder bearing mechanism; The material scraping plate and the stock guide that are provided with in the cylindrical shell; Roller group and roller supporting fixed device that the some rollers that are provided with in feed and exhaust tube that the cylindrical shell top and the bottom are provided with and the cylindrical shell are formed; It is characterized in that: described roller group comprises a breast roll and centers on the limit roller of breast roll more than two or two.
Described limit roller around breast roll is formed by being limit roller A, limit roller B, the limit roller C that star distributes with breast roll.
Be provided with stock guide between described limit roller A and the limit roller B that is adjacent, the top of limit roller B is provided with material scraping plate.
The vertical direction of described limit roller A and limit roller B central axis is separately installed with pressue device.
Described pressue device can adopt hydraulic pressure or air pressure or groups of springs.
The utility model course of work is as follows: cylindrical shell is rotated by drive mechanism, thereby the roller group does corresponding constant speed rotation in the drive cylindrical shell, material is fallen on the cylinder inboard wall by feed pipe, be broken when rotating to a place, point of contact of limit roller A and cylindrical shell with cylindrical shell, thereupon successively through the b of limit roller B point, the tangent c of the place point of limit roller B and breast roll, limit roller A and the tangent d of the place point of breast roll are after fragmentation is milled step by step, outside discharge nozzle is discharged mill.Spacing between spacing that above-mentioned b, c, d are ordered and limit roller A, limit roller B and the cylindrical shell can require to carry out online or the off-line adjustment according to grinding process.If 4,5,6 or more limit roller are installed in the cylindrical shell, its operation principle is identical, the course of work and the like.
The utility model compared with prior art has following characteristics:
The material that granular size is different in same grinding machine by the subregion fragmentation, fragmentation and grinding pressure have been reduced, improved general roll-type grinding thickness material to greatest extent and mixed, the situation that disposable instantaneous high pressure is pulverized (the material bed is pulverized), thus energy is used more effectively.
The rotating speed of cylindrical shell can be online or off-line adjust significantly, its operational factor is more become rationally, performance indications are more optimized, energy-saving effect is more remarkable.Result of the test shows, can grind energy-conservation about 20% by general tube roller, finished product output and fineness can be adjusted in wide range, make improvements slightly, also can realize superfine grinding, very likely instead of ball mill, conventional roller mill and be widely used in the grinding operation of cement, lime stone, ferrous and nonferrous metals ore, coal, medicine and some industrial chemicals.
3. be not difficult to find out also from above structure that material is in case after being seized broken limit roller, its most of crushing force is delivered to cylindrical shell step by step by breast roll and changes into internal force; When the rigidity of cylindrical shell and torque are enough big, this a pair of active force and reaction force will make the material grinding that is broken; To most of raw materials of industry such as iron ore, clinker, lime stone, coal etc., when specification of equipment hour, under the condition that does not apply external force (as hydraulic coupling), can rely on internal force and pulverized.Saved the fluid power pressue device, made milling equipment become fast, little, light, made and maintenance cost thereby greatly reduce.
(4) description of drawings:
Fig. 1 is the main apparent direction structural representation of an embodiment of the utility model;
Fig. 2 be among Fig. 1 H-H to the sectional structure schematic diagram.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, comprise cylindrical shell 1 in the present embodiment, drive the driving mechanism 2 that cylindrical shell rotates, cylinder bearing seat 3, be provided with by a breast roll 4 in the cylindrical shell, be limit roller A5, the limit roller B6 of star distribution, the roller group that roller C7 three limit rollers in limit are formed around breast roll and with breast roll, feed pipe 8 is equipped with on cylindrical shell top, discharge nozzle 9 is equipped with in the bottom, roller axle 10, bearing 11 and bearing block are fixed by the roller support of bearing 12 supports, and wherein roller bearing 11 can directly be loaded on the roller axle and also can be contained in the roller.Between limit roller A, limit roller B, stock guide 13 is housed, above the roller B of limit, material scraping plate 14 is housed.In addition, in order to strengthen brokenly the required pressure of grind materials, vertical direction at limit roller A and limit roller B central axis is equipped with air pressure, hydraulic pressure or spring pressue device 15 respectively, its pressure acts on the roller axle, adjustment by the roller axle reaches adjustment breast roll and limit roller A, limit roller B, the spacing between cylindrical shell and limit roller A, the limit roller B.Simultaneously, can be by the purpose that the speed change gear (not shown) realizes online or off-line speed governing be set in driving mechanism.
