Superfine crushing device and superfine crushing method for preparing mixed feed

Abstract

The invention discloses a superfine crushing device and a superfine crushing method for preparing mixed feed. The superfine crushing device comprises a lifting machine, a first pulse dust collector, a mixing machine, a vibration feeding machine, a crushing machine, a cyclone separator, a second pulse dust collector and an induced draught fan which are arranged sequentially, wherein the first pulse dust collector is fixedly arranged at the outer wall of the lifting machine, a material outlet of the first pulse dust collector is positioned above a material inlet of the mixing machine, the vibration feeding machine is positioned between a material outlet of the mixing machine and a material inlet of the crushing machine, a grading machine is arranged at a material outlet of the crushing machine, the material outlet of the crushing machine is connected with a material inlet of the cyclone separator through the grading machine, and a dust outlet of the cyclone separator is sequentially connected with the second pulse dust collector and the induced draught fan. The superfine crushing method comprises the following steps of material feeding, material mixing, crushing, and dedusting and collecting. The superfine crushing method has the advantages that the crushing temperature is controlled below 60 DEG C, the dissolving of the material in the crushing machine can be effectively prevented, the crushing effect is better, and the material mixing is uniform.

Description

technical field [0001] The invention belongs to the technical field of material mixing and pulverization, and in particular relates to a superfine pulverization device and a superfine pulverization method for preparing mixed feed. Background technique [0002] In the feed preparation process, steps such as mixing and crushing are generally required, and the crushing process usually uses a pulverizer to crush the feed. The existing pulverizer mainly uses the relative rotation of the stator and the hammer to pulverize the material. After pulverization, the material with qualified pores is discharged from the screen, and the unqualified material continues to be pulverized. The pulverization particle size of this pulverizer is generally smaller Large, and the uniformity of crushing is not high. The crushing particle size is relatively large, resulting in a low mixing degree between the main material and the auxiliary material. This kind of feed is not easy to be absorbed by the...

Problems solved by technology

The existing pulverizer mainly uses the relative rotation of the stator and the hammer to pulverize the material. After pulverization, the material with qualified pores is discharged from the screen, and the unqualified material continues to be pulverized. The pulverization particle size of this pulverizer is generally smaller Large, and the uniformity of crushing is not high

The crushing particle size is relatively large, resulting in a low mixing degree between the main material and the auxiliary material. This kind of feed is not easy to be absorbed by the fed animals. At the same time, for some raw materials with low melting point, the temperature is too high during high-speed crushing, which is easy Cause raw materials to dissolve, and then paste on the pulverizer, the pulverization effect is poor
