Hammer sheet crusher

Abstract

The invention discloses a hammer sheet crusher. The hammer sheet crusher comprises an upper body, a main motor arranged outside the upper body, a main shaft connected with the main motor, a sieve plate, hammer sheets, a rotating shaft moving cutter and an auxiliary motor, the hammer sheets are arranged on the main shaft, the sieve plate is arranged outside the hammer sheets and is arranged in the upper body around the main shaft, the auxiliary motor is arranged outside the upper body, the rotating shaft moving cutter is arranged in the upper body and parallels to the main shaft, and the rotating shaft moving cutter is connected with the auxiliary motor. How to improve the crushing capability of the crusher and destroy a circulation layer in the crusher is a technique problem to be solved. The hammer sheet crusher which adopts the rotating shaft moving cutter driven by the auxiliary motor increases the cutting force to a material and is in favor of destroying the circulation layer of the material in the crusher, so the crushing efficiency and the crushing quality are effectively improved.

Description

[0001] technical field [0002] The invention relates to a crushing and processing machine for food and feed, in particular to a hammer mill. Background technique [0003] The crushing of feed raw materials is a very important link in feed processing. Through crushing, the specific surface area of ​​raw material particles per unit mass is increased, and the dissolution of feed in animal digestive juice is increased, which is beneficial to digestion and improves the digestion and absorption rate. In addition, the size of raw material particles will also affect the difficulty of subsequent processing of feed and the uniformity of product quality to a large extent. [0004] The invention patent CN102049333A discloses "A Hammer Mill" which discloses that the hammers with different lengths of the grinder are on different spiral curved surfaces, so that multiple hammers of the grinder are in different layers to improve the crushing efficiency. Invention patent CN1463803 discl...

AI Technical Summary

Problems solved by technology

At present, the development of fish feed, shrimp feed and other aquatic products is relatively rapid, and the aperture of the sieve plate for the production of aquatic feed is relatively small, only 1mm or even smaller, so the thickness of the sieve plate is very thin (generally the thickness is similar to the aperture), by This causes the middle part of the sieve plate to be easily concave, and the middle part of the sieve plate is easily damaged by collision with the hammers on the rotor shaft, resulting in serious waste. Crushing is carried out on the same material layer, so the material is driven by the hammer, and it is easy to form a powder circulation layer on the surface of the sieve plate. It rotates circumferentially with the hammer, preventing the powder from passing through the sieve hole, and affecting the output of the pulverizer. , especially when using a small-aperture sieve plate (aperture diameter φ1.5mm or less), the output reduction is particularly obvious
