A superfine pulverizer that can destroy material circulation during crushing

Abstract

The invention discloses an ultrafine grinder capable of destroying a circulation layer of ground materials. The ultrafine grinder comprises a machine frame, a purifying chamber arranged on the machine frame, a grinding chamber arranged on the top of the purifying chamber, a discharging chamber arranged on the top of the grinding chamber, a grinding main shaft arranged inside the purifying chamber, a grinding shaft drive motor for driving the grinding main shaft to rotate and a feeding system installed on the machine frame. The ultrafine grinder further comprises blowing systems, pulse control valves, a pulse control device and a gas storage tank; the side wall of the grinding chamber and the side face of a gear ring are provided with communicated through hole sets; blowing pipes of the blowing systems extend into the through hole sets; a gas outlet of the gas storage tank is connected with gas inlets of the blowing systems through the pulse control valves; the control signal output end of the pulse control device is connected with the control signal input ends of the pulse control valves. Compressed air serves as power to effectively destroy the circulation layer generated by the ground materials.

Description

technical field [0001] The invention relates to equipment for ultrafine pulverizers in grain, oil and feed processing plants, in particular to an ultrafine pulverizer capable of destroying material circulation during pulverization. Background technique [0002] Ultrafine pulverizer is mainly used in feed mills to pulverize various coarsely crushed materials such as corn, sorghum, rice and wheat, soybean meal, fish and shrimp, etc. to achieve the required standard of ultra-fine-grained materials, especially suitable for shrimp, soft-shelled turtle, eel and micro- or ultra-fine grinding of feed for young animals. [0003] The ultrafine pulverizer is generally composed of a frame, a clean room, a pulverizing room, a discharging room, a pulverizing spindle system and a feeding system. The outlet of the feeding system and the inlet of the pulverizing chamber are directly connected with bolts. The pulverizing spindle system is installed in the purification chamber on the frame.

AI Technical Summary

Problems solved by technology

cause high energy consumption

Directly increase the cost of feed processing

[0006] Third, the configuration of multiple ultrafine pulverizers also causes an increase in corresponding equipment

The increase in the area of ​​the entire plant will increase the construction cost significantly
