Embodiment Construction

[0023] The invention provides a method for improving the crushing efficiency of a hammer mill. Figures 1 to 2 are schematic diagrams of the structure of a hammer mill. In the figure, the main shaft 2 is fixed on the frame of the hammer mill (not marked in the figure), the positioning plate 1 is fixed on the main shaft 2, and fixed with the hammer 4 through the connecting pin 3, and the sieve plate 5 is located under the hammer 4 , the hammer head part of the hammer 4 is just in the groove of the sieve plate 5, and the material 6 also just falls in the groove of the sieve plate 5.

[0024] The working process of the present invention: after the material 6 to be crushed enters the pulverizer, it will automatically enter the groove of the sieve plate 5 and be forcibly hit by the high-speed rotating hammer 4 (the high-speed rotating hammer 4 moves in the groove) ), the whole structure of the sieve plate 5 is composed of several grooves, the number of grooves on the sieve plate 5 ...

Abstract

The invention pertains to feedstuff processing technological field of agricultural engineering, relating to a method to improve the grinding efficiency of a hammer grinder for the processing of fine powder of feedstuff materials. The sieving areas of sieve plates of the hammer grinder are combined with altering of hammer parameters; To-be-ground materials enter into a grinding chamber and automatically come into troughs of the sieve plates, the high speed rotating hammers move in the troughs, and the to-be-ground materials are forcedly hit by the high speed rotating hammers; the whole sieve plates consists of a plurality of troughs, while the number and shape-structure parameters of the troughs of the sieve plates should be matched and consistent with the arrangement of the hammers. Moreover, since the altering of the structure of the sieve plates, the resistance of material circulation is increased, both factors comprehensively and dramatically enhance the hitting efficiency of the hammers, which can not only solve the problem that ordinary horizontal hammer grinder used for fine grinding of feedstuff materials, but also greatly enhance the grinding efficiency by 20 to 30 percent.

Description

technical field [0001] The invention belongs to the technical field of feed processing in agricultural engineering, and in particular relates to a method for improving the crushing efficiency of a hammer mill when feed raw materials are processed into fine powder (the particle size of the crushed product is below 1 mm). Background technique [0002] Horizontal hammer mill is a kind of crushing equipment commonly used in the feed production process. It has a wide range of applications. However, various horizontal hammer mills generally use ring-shaped flat sieve plates. In order to meet the requirements of fine powder materials of 1mm or below, people have done a lot of research work starting from the parameters that affect the hammer mill, in order to break the pulverizer to crush the indoor circulation layer, increase the effective screening area, and improve the impact of the rotary hammer on the material. strike efficiency, etc. This has always been a hot issue in the re...
