Abstract

The invention discloses a crusher. The crusher comprises a box body and a crushing mechanism, the crushing mechanism is arranged in the box body, the crushing mechanism comprises a rotating shaft, circular rings, supporting bars, fixed arms, hammerheads and a fixed shaft, the circular rings comprise an upper circular ring and a lower circular ring, the radius of the upper circular ring is consistent with the radius of the lower circular ring, the two circular rings are correspondingly arranged in parallel, the supporting bars are fixedly connected between the two circular rings, the rotating shaft is arranged in the centers of the circular rings, the rotating shaft is vertical to the circular surfaces of the circular rings, the circular rings and the rotating shaft are fixed through the fixed arms, the hammerheads are arranged on the supporting bars, the fixed shaft is arranged in the center of the box body, one end of the rotating shaft is movably fixed on the fixed shaft, and the other end of the rotating shaft is arranged outside the box body. The design of bidirectional hammerheads makes ores born several times in the bumping process with the hammerheads, so the ores are well crushed, and the crushing time of the ores is greatly shortened.

Description

A kind of pulverizer

Technical field

The present invention relates to a kind of pulverizer, particularly relate to a kind of pulverizer for quartz mine.

Background technology

The current beater grinder inspecting use, it is all horizontal pulverizer, all rotated by the single direction of motor, drive tup collision and extrude ore grinding ore, the direction of rotation is single causes the collision of tup and ore can only act in a direction, makes to need long collision just can take pulverizing object to, the energy consumption in crushing process can not be effectively reduced, the collision efficiency made is low, and the ratio of reduction is low, and the cost in process of producing product increases.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, provide a kind of bidirectional force effect, collision efficiency is high, the pulverizer that comminution ratio is high.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of pulverizer, described pulverizer comprises casing and disintegrating mechanism, disintegrating mechanism is arranged in casing, disintegrating mechanism comprises rotating shaft, annulus, support bar, fixed arm, tup and axle are fixed, annulus is divided into upper and lower two annulus, annular radii is consistent, the corresponding parallel placement of two annulus, support bar is fixedly connected with between two annulus, rotating shaft is arranged at circle ring center, the vertical annulus disc of rotating shaft, annulus and rotating shaft are fixed by fixed arm, tup is arranged on support bar, axle is fixedly installed on casing center, the activity of rotating shaft one end be fixed on axle fixing on, the other end is arranged at outside casing.

Described pulverizer also comprises motor, and motor is provided with two, and be arranged at the outer two ends up and down of casing respectively, motor and rotating shaft are fixedly installed.

Described disintegrating mechanism has two, is arranged at casing internal upper part and bottom respectively, two corresponding vertically placements of disintegrating mechanism.

The number at least 3 of described tup on each root support bar.

The section of described tup is trapezoid, and lower surface is scarf, and it is the direction that disintegrating mechanism rotates that scarf meets right direction, and hammer head material is zirconia tup.

Described cabinet wall is equipped with one deck aluminium oxide pad.

Compared with prior art, the beneficial effect had is: the design of two-way tup make ore with the collision process of tup in carry out repeatedly stressed effect, better can carry out fragmentation to ore, ore also greatly reduces on the time of fragmentation.

Detailed description of the invention

Pulverizer as shown in the figure, comprise support 1, casing 2, motor 3, rotating shaft 4 and disintegrating mechanism, support is space frame structure, casing is cylindrical tank body structure, box house center is provided with axle and fixes 9, top is provided with charging aperture, bottom is provided with discharging opening, casing is fixedly installed in internal stent, motor is two, be mounted on the top and bottom of casing outside respectively, rotating shaft is two, be fixedly connected with power-on and power-off machine rotor respectively, rotating shaft inserts box house from casing upper end center is vertical with casing lower center respectively, and upper and lower rotating shaft position is just to placement, the axle that casing center is fixed in upper lower rotary shaft activity is fixed, disintegrating mechanism has two, be divided into disintegrating mechanism and lower disintegrating mechanism, two disintegrating mechanisms are oppositely separately fixed on lower rotary shaft, disintegrating mechanism comprises annulus 5, support bar 6, fixed arm 8, tup 7, annulus is upper and lower two, be fixedly connected with respectively by the vertical annulus of support bar between two annulus, arch brace bar quantity is at 12, support bar is evenly distributed on annular ring peripheral, two annulars concentrically circle are arranged and are fixedly connected with by fixed arm, fixed arm quantity is 3, fixed arm one end is fixed in the rotating shaft in the annulus center of circle, one end is uniformly distributed around circular, circumferential, tup is fixedly installed on support bar, the number of tup on each root support bar is 3, and tup is stratiform alternately evenly arrangement, and the section of tup is trapezoid, and lower surface is scarf, and it is the direction that disintegrating mechanism rotates that scarf meets right direction, and hammer head material is zirconia tup, the tup scarf of upper disintegrating mechanism is below tup, and the scarf of the tup of lower disintegrating mechanism is above tup, cabinet wall is equipped with one deck aluminium oxide pad.

During work, start upper and lower motor, disintegrating mechanism inverted running, feeding port pours ore into, ore enters in casing and collides with tup, because tup is arranged and scarf, scarf is square rotates square ore for tup and scarf collides due to the principle of active force, ore can upwards or downwards in a disguised form move, again can break-in when encountering below or top tup, constant collision process, this process is more than 2 times of horizontal pulverizer collision rate, specific breakage rate increases greatly, and degradation rate also increases greatly.
