Abstract

The invention discloses a dual-rotor vertical-shaft crusher. The dual-rotor vertical-shaft crusher comprises rotors and crushing anvil blocks, wherein the rotors are arranged in the crusher and rotate at high speed; the crushing anvil blocks are arranged at the peripheries of the rotors along the radius direction; materials which are fed into rotors rotating at high speed are discharged from discharge openings around the rotors via the centrifugal force effect, and collide with the crushing anvil blocks so as to be crushed; the crushed materials are discharged from an engine body under the action of gravity from the part between the rotors and the crushing anvil blocks. The dual-rotor vertical-shaft crusher is characterized in that the crushing anvil blocks arranged at the peripheries of the rotors along the radius direction are uniformly distributed along the peripheral direction, and are fixed on a seat ring via bolts; the seat ring can rotate by the driving of a power element.

Description

A kind of birotor vertical shaft crusher

Technical field

This practicality invention relates to a kind of birotor vertical shaft crusher without buildup mode.

Background technology

As everyone knows, it is main fragmentation that current vertical shaft impact crusher is used for carrying out sand processed to the raw material such as rock, ore, and described disintegrating machine, according to the broken form of raw material, is roughly divided into two kinds of modes, and one is straight broken formula, and one is bed of material formula.The former mainly carries out fragmentation to material, makes raw materials size from large to small, and the latter mainly carries out shaping to material, material and material impacting, and material impacting is in heap buildup, and on stockpile, slip, friction etc. make the water caltrop of material be polished, and reach the effect of shaping.

As shown in Figure 4, the power that belt pulley 2 on motor 1 rotates, by belt 3, main shaft wheel 4 is rotated, thus rotor 8 is rotated, be contained in the center material cone 9 on rotor 8, material enters crusher chamber in the direction of the arrow from the top of equipment, by the upper feeding ring 12 on upper bracket 11, pass downwardly through intermediate feed ring 10 again, fall in the rotor 8 of High Rotation Speed, material passes through center stockpile 9 in rotor 8, because of the High Rotation Speed of rotor 8, material is accelerated, dish out with certain speed, clash into seat board 7, and be broken, disperse, the material of simultaneously constantly dishing out, and also there is shock between material before, friction, raw meal particle size is reduced further, finally flow out crusher chamber downwards.Be arranged on blanking port place backplate circle 6 play a part protect body, diagram 5 be material by the route entered out.

As shown in Figure 5, the power that belt pulley 2 on motor 1 rotates, by belt 3, main shaft wheel 4 is rotated, thus rotor 8 is rotated, be contained in the center material cone 9 on rotor 8, material enters crusher chamber in the direction of the arrow from the top of equipment, by the upper feeding ring 12 on upper bracket 11, pass downwardly through intermediate feed ring 10 again, fall in the rotor 8 of High Rotation Speed, material passes through center stockpile 9 in rotor 8, because of the High Rotation Speed of rotor 8, material is accelerated, dish out with certain speed, clash into the stockpile layer 7 of raw material, material clashes on stockpile layer 7, roll, slide, grinding, the material of simultaneously constantly dishing out, and also there is shock between material before, friction, grinding, make the corner angle passivation of material, granularity reduces further, to improve the quality of goods, finally flow out crusher chamber downwards.Be arranged on blanking port place backplate circle 6 play a part protect body, diagram 5 be material by the route entered out.

But in existing disintegrating machine, due to seat board 7(Fig. 4) or stockpile layer 7(be Fig. 5) be all in body, actionless, rotor is only had to accelerate material, and the acceleration of rotor always has a definite limitation, this just have impact on the crushing effect of material, thus exists and improves the low of crushing efficiency, affect the production problems of broken goods.

Summary of the invention

Object of the present invention provides a kind of birotor vertical shaft crusher for above-mentioned the deficiencies in the prior art.

A kind of birotor vertical shaft crusher of the present invention comprises the rotor being arranged on High Rotation Speed in disintegrating machine and the broken anvil block arranged along radial direction in rotor periphery, the material dropped in High Rotation Speed rotor is discharged by the discharge gate of centrifugal action from peritrochanteric, clash into above-mentioned broken anvil block and pulverized, crushing rear material discharges body under gravity between described rotor and broken anvil block, it is characterized in that: the broken anvil block arranged along radial direction in rotor periphery is along the circumferential direction uniform, and be bolted on seat ring, seat ring can rotate under the driving of power original paper.

An inclined-plane is respectively had before and after above-mentioned broken anvil block has, front bevel has an inclination angle forward in the vertical direction, the material after clashing into inclined-plane is caused to have a downward speed, crusher chamber is passed through to accelerate material, improve the flow of material, upper described broken anvil block rotates with certain speed, then can aggravate material and broken anvil block clashes into degree, and the crushing effect of material is more obvious.

On described broken anvil block, front bevel inclination angle is in the vertical direction in the scope of 10 °-18 °.
