Abstract

The utility model discloses an adjustable hammer head fine crusher, comprising a pre-crushing device and an adjustable hammer head. The upper part of the pre-crushing device is a centrifugal spreading disk and the lower part is a guide plate with the angle of inclination of 60-85DEG. The adjustable hammer head is provided with 2-6 striking heads with different lateral length. Because the pre-crushing device is added, the stress centralization and the abrasion of the hammer head are lowered, and the efficiency is increased by 35%. The adoption of the adjustable hammer head ensures fine and uniform discharge granularity as well as small granularity fluctuation. Simultaneously, the service life of the hammer head is extended and the cost is saved by 60 percents.

Description

Adjustable tup fine crusher

The utility model relates to the crushing mechanism in a kind of building materials, mine, metallurgy, the chemical industry.

At present its major defect of all kinds of disintegrating machines that uses is: crushing mechanism discontinuity, tup wearing and tearing are very fast, the discharge granularity of inefficiency, energy consumption height, material is difficult to control.

The purpose of this utility model provide a kind of tup can regulate, simple in structure, stressed evenly, the ratio of reduction is big, efficient is high, energy consumption is low, material is discharged the fine crusher that granularity is easy to control.

In order to achieve the above object, be provided with precrushing device and adjustable tup in the utility model, precrushing device top is centrifugal spreading disk, and the bottom is a stock guide, and the stock guide inclination angle is 60 °～85 °; Adjustable tup is provided with the attacking head that 2～6 lateral lengths differ.

The utility model has the advantages that: increase the precrushing device, reduced stressed concentrating, the abrasion of tup, efficient has improved 35%; Adopted adjustable tup, guaranteed that marker size is thin and evenly, the granularity fluctuation is little, tup has improved service life and cost saving 60% simultaneously.

Below in conjunction with drawings and Examples the utility model is described.

Fig. 1 is the utility model structure chart.

Fig. 2 is adjustable hammehead structure figure of the present utility model among the embodiment.

(1) motor, (2) loam cake, (3) charging aperture, (4) main shaft, (5) centrifugal spreading disk, (6) counterpunch board, (7) stock guide, (8) backplate, (9) rotor, (10) adjustable tup, (11) liner plate, (12) material baffle, (13) base, (14) hopper, (15) shaft coupling, (16) cylindrical shell, (17A), (17B), (17C) attacking head among the figure.

During work, motor (1) drives main shaft (4) rotation at a high speed, and main shaft (4) drives centrifugal spreading disk (5), and when material enters the operating room through charging aperture (3), the centrifugal spreading disk (5) that material is at first fallen rotation is at a high speed gone up and clashed into mutually with counterpunch board (6); After carrying out precrushing, clashed into mutually with counterpunch board (6) again through last the dishing out of backplate (8) that stock guide (7) is forced to enter next workspace; Because the effect of reaction force, be bound on the short attacking head (17A) of adjustable tup (10) lateral length by counterpunch board (6) counterattack, collide liner plate (11) after catching a packet once more, in cavity, form repeatedly circulation, material is fallen material baffle (12) and is gone up the accumulation of formation nature, material in the accumulation constantly is subjected to counterattack, hits, the material that impacts washes away, because fines good fluidity, at first from windrow, be slipped on next backplate (8), be subjected to again a series ofly dishing out, strike back, hitting and be broken, from hopper (14), discharge at last.

When liner plate (11) thickness wear down, regulate adjustable tup (10), use attacking head (17B), work on.

Regrind when thin when liner plate (11) thickness, regulate adjustable tup (10), use attacking head (17C), work on.

Claims

Adjustable tup fine crusher, be made up of main shaft, counterpunch board, backplate, rotor, tup, liner plate etc., it is characterized in that being provided with precrushing device and adjustable tup, precrushing device top is centrifugal spreading disk, the bottom is a stock guide, and the stock guide inclination angle is 60 °～85 °; Adjustable tup is provided with the attacking head that 2～6 lateral lengths differ.
