Operation principle of the present invention is: as shown in Figure 1, be connected with feeding part, rotating part, output section, main motor one end in turn through reductor deceleration, the motion of driving gear engagement driven gear drive rotating part; And the output section is provided with ventilation duct, is used for making flour mill be in the negative pressure duty to the inner wind of mending of rotating part, utilizes product to collect; The main motor other end is connected with drive unit at a slow speed, and drive unit mainly uses when maintenance and installation liner plate at a slow speed.
As shown in Figure 2, charging aperture with abrasion-proof backing block is arranged, said abrasion-proof backing block is welded on the feeding part, feeding part is provided with material-pulling device, is causing the solid accumulation can't be smooth and easy during the entering rotating part because of cause specific, plays the pusher effect.Feeding part directly puts in charging end cap the inside, and the feed end gland that is embedded with sealing device with feeding part and on feed end hollow axle journal; Feed end hollow axle journal is sitting on the base bearing, and base bearing is cast with babbit on bush seat, be provided with point for measuring temperature, peep hole and oil-spraying device, the base bearing that is sitting in as support through base directly with foundation bolt and.Charging end cap inwall passes through bolt handle and end cap liner plate, and is lined with rubber blanket between the two.The big end of charging end cap is connected with shell flange through high-strength bolt, and shell flange and cylindrical shell weld together, and cylinder inboard wall passes through bolt handle and shell liner, and has manhole door on the cylindrical shell, is used to pass in and out liner plate and scarfing cinder.Other end discharging end cap connects firmly shell flange through high-strength bolt; Discharging end cap inwall through bolt successively with press strip and frid; Press strip is pressed against shifting board on the frid, and frid covers through the bolt handle with at discharge end, and discharging end cap corrugated sheet is pressed against on the frid through bolt.Discharging spiral and discharging end cap through bolt with.Discharging end cap axle journal is sitting on the base bearing; Fit in discharging end cap axle journal inner radius and output section; And the discharge end gland that is embedded with sealing device with the output section and on discharging end cap axle journal, discharging end cap axle journal outer radius connects firmly driven gear, and driven gear with gear cover is arranged; Gear cover is provided with the glycerine injection apparatus, the timed lubrication flank of tooth; Driven gear and driving gear engagement.
As shown in Figure 3, all staggering in the gap between frid and the frid, between the end cap liner plate, avoids forming ring-shaped groove and the cylindrical shell that weares and teares; Small powder in the raw material is fed by feed end, falls into cylindrical shell bottom centre equably along end cap liner plate face; To the both sides diffusion, the bulk in the raw material has bigger kinetic energy then, always a trend side far away; But wherein some must be collided with two crownings of end cap corrugated sheet, returns to opposite side then, therefore bulk is evenly distributed; The particle that below the discharge end edge, returns also falls into the center of cylindrical shell bottom equably, and to the both sides diffusion, bulk and particulate move at cylindrical shell vertically then; Direction is just in time opposite, has just produced milling action.The collision of the particle mutual extrusion that grinds less than the particle in shifting board space, enters into second storehouse along the space of shifting board, drives and makes particle entering discharging spiral down at the material boss of dialling of frid, finally gets into the output section.
The invention has the beneficial effects as follows: simple and compact for structure, easy to use, handling safety improves discharging speed, enhances productivity;
Crushing efficiency is high, can make the thing piece of diameter 300mm, and through after once grinding, granularity can be less than 0.074mm, in saving, operation in small, broken bits, more simplifies crushing circuit than existing pulverizer, and reduction equipment investment and regular maintenance and administrative expenses.
No powder grinding medium does not have other metallic objects and sneaks in broken mill process, improved product gas purity and precision, is different to have the grinding machine of making abrasive body of steel ball now, all sneaking into of a large amount of iron can be arranged in the product.
Shell liner adopts the rare earth alloy liner plate, and is fixed with the lifting bar, and discharging improves outside the abrasion resistance of cylindrical shell, most importantly can it tumbled by the state that rushes down, and material impacts grinding each other and pulverizes.
Have pointed convexity on the end cap liner plate,, take place to come and go spring after the material collision, thereby the mixing material effectively prevents the generation of segregation phenomena, improve the service life that has also prolonged the equipment consumable accessory when breaking the mill effect because pointed convexity is oppositely arranged.
Gear wheel is arranged on the discharge end hollow axle journal, is different from the existing structure on the cylindrical shell that is arranged on, and satisfies under the prerequisite of using, and the equipment of having saved takes up an area of space and equipment consumptive material.
The present invention is applied in the production of broken aluminium oxide crust piece.
