Abstract

The utility model relates to a vertical counterblow hammer type crusher. A motor drives a hammer head fixed on a main shaft to hammer materials struck by a counterblow plate in a counter mode after flung from a tray. The materials are struck for many times, drop onto a holding ring to pile up. The piled materials have flushing with struck materials and materials struck in a counter mode, slide to a next flinging, counter-striking, hammering and flushing process, and finally are discharged outside a cavity body. The utility model organically combines the crushing processes of flinging process, counter-striking process, hammering process, flushing process, etc., together to enable the materials to obtain fine crushing. The utility model has the advantages of low power consumption, low abrasion of easy-to-wear parts, simple structure and convenient used and maintenance.

Description

Vertical and anti-beater type crusher

The utility model relates to a kind of size reduction machinery, a kind of vertical impact hammer mill of more specifically saying so.

The hammer mill that generally uses is counter beating hammer type disintegrator (horizontal), vertical-spindle hammer crusher and vertical impact crusher etc. at present.Counter beating hammer type disintegrator is to utilize the tup of rotation at a high speed to hit material, make material obtain certain kinetic energy, fly to counterpunch board, material is subjected to flying out after the counterpunch board counterattack, be subjected to the strike of tup once more, after this form several times circulates, last material is fallen on the grid section, continues to be subjected to the strike and the milling of tup, and qualified material is discharged cavity through the seam of combing.It is few that this disintegrating machine makes material catch a packet, strike back number of times, and epitrochanterian tup can not be in operates at full capacity, tup serious wear during the milling material on grid section, the easy putty of seam of combing simultaneously.The groundwork principle of vertical-spindle hammer crusher is: material is subjected to the at a high speed strike of the tup of rotation of each row in charging aperture in axial direction enters broken cavity, and part is subjected to milling between tup and liner plate, is discharged from cavity after reaching certain fineness.This disintegrating machine exists discontinuity to the strike of material, upper and lower tup, upper and lower wear liner inequality, and raw meal particle size is difficult for guaranteeing, and the maintaining difficulty is big.Vertical impact crusher is that the material that utilizes the high speed rotor rotated will fall in the rotor is dished out at a high speed, wash away mutually with the solid accumulation of chamber wall, wash away the fine grained material easily earlier from solid accumulation landing get off and screenedly go out cavity, the coarse granule material continues to form to pile up and washes away mutually with constantly sudden material and pulverized.This disintegrating machine exists rotor speed and requires height, the consumable accessory quick abrasion, and it is few that material is washed away number of times.

The purpose of this utility model provides a kind of vertical impact hammer mill, material is subjected to a series of projectile impact, hammering, strikes back, washes away in broken cavity, be discharged from cavity after making material reach certain fineness, and the capacity usage ratio height, working service is convenient.

The purpose of this utility model can realize in the following manner: a kind of vertical impact hammer mill comprises cylindrical shell, it is fixed with loam cake and base respectively in two ends up and down, the main shaft two ends be placed in respectively base and on cover, be fixed with rotor on the main shaft, be mounted with several tups in the groove of rotor, be fixed with pallet on the upper surface of rotor, make the material fallen on the pallet by impelling to the counterpunch board that is fixed on cylindrical shell, described counterpunch board is fixed on the cylindrical shell by press strip and filler ring, feed hopper is fixed on and covers, hopper is fixed on the base, main shaft by the V-belt by motor drives.

The utlity model has following advantage: with projectile impact, counterattack, hammering, a series of crumbling methods such as wash away and organically combine, make material reach in small, broken bits, and low in energy consumption, the consumable accessory wearing and tearing are few, simple in structure, the working service aspect.
