Abstract

The utility model relates to a crusher hammer sheet. A main body thereof is plate-shaped; the upper part is provided with an installation hole; the cross sections of both sides of the hammer body of the upper part in the main body are acute angles and are A-shaped. Under the condition that the hammer sheet rotates at a high speed, a circulation layer is degraded so that materials are concentrated near a sieve sheet on the top end of the hammer sheet under the action of centrifugal force and negative pressure, which creates excellent conditions for the striking and the sieve hole penetration of the materials. The cross sections of both sides of the hammer body of the lower part are widened, are thickended and are V-shaped; the cross sections of both sides of the top end of a hammer head are arc-shaped. Under the condition that the linear velocity of the hammer sheet keeps constant, the striking strength of the hammer sheet to the materials is enhanced. Thus, crushing efficiency is improved and energy consumption is reduced.

Description

Hammer mills

Technical field

The utility model belongs to field of crushing equipment, relates to a kind of hammer mills.

Background technology

A kind of disintegrating apparatus that industry such as pulverizer is domestic and international feed, brewage is generally used, hammer leaf is the core work parts of pulverizer, the quality of hammer leaf quality, performance is to having the greatest impact of crush efficiency.

The hammer leaf of present beater disintegrating machine both domestic and external is square template sheet, two lateral sections are flat type, section parts straight in the work is hit material on high speed rotor rotated dish, under the inoperative position of hammer leaf drives, material is at the sieve sheet, the outside of tooth plate and rotor disk forms circulation layer, because the strike position of hammer leaf mainly concentrates on the top of hammer leaf, the formation of circulation layer make this broken material granule under the effect of circulation layer extremely difficulty pass through sieve aperture, thereby greatly reduce crush efficiency, increased energy consumption, this is to pulverize the industry urgent problem at present.

Summary of the invention

The purpose of this utility model is to provide a kind of degradable circulation layer, increases hitting dynamics, improves crushing efficiency, the hammer mills that cuts down the consumption of energy.

The technical solution adopted in the utility model: a kind of hammer mills, its body is an en plaque, and top is provided with installing hole, and hammer body two lateral sections, middle and upper part of described body are acute angle, are the A font.

Hammer body two lateral sections, bottom of described body are V-shape.

Two lateral sections, tup top of described body are circular arc type.

The positive beneficial effect that the utility model had:

1. hammer both sides, body middle and upper part Cross section Design is an acute angle, be the A font, under the situation that hammer leaf rotates at a high speed, the circulation layer of having degraded, material is being focused near the hammer leaf top sieve sheet, for the strike of material and pass through sieve aperture and created excellent condition under the effect of centrifugal and negative pressure;

2. adopt the tungsten carbide built-up welding to handle, hammer body two lateral sections, bottom are widened, thickening, the tup top is up the time, be V-shape, two lateral sections, tup top are circular arc type by existing flat type built-up welding, under the constant situation of linear velocity 86 meter per seconds that keep hammer leaf, increased the hitting dynamics of hammer leaf, improved crushing efficiency material;

Through six and enterprise of good standings such as group, Zhengda Group, the auspicious group of wind, nine groups, group of Xingda, positive rainbow group on probation, effect is obvious, with water droplet king 968-II type is example, economize on electricity 13%-18% capable of reducing energy consumption, the existing hammer leaf of crush efficiency improves 30%-80%, 0.12 yuan of-0.15 yuan/T of cost performance is time saving and energy saving, economical and practical.
