Circulating impact flour milling machine unit and circulating impact flour milling method by using circulating impact flour milling machine

Abstract

The invention discloses a circulating impact flour milling machine unit and a circulating impact flour milling method by using a circulating impact flour milling machine. The unit comprises a machine housing; a screen is mounted in the machine housing; a cleaning bin and a screening bin are arranged in the screen; a circulating screen mesh and a grading screen mesh mechanism are arranged in the screening bin; the impact flour milling machine is arranged in the machine housing; a screen body feed opening and a circulating feed opening are formed in the top of the screen; the cleaning screen mesh used for separating impurities is arranged in the cleaning bin; the discharge opening of the impact flour milling machine is connected with a flour milling machine discharging pipe; after being bent, the upward extending flour milling machine discharging pipe is connected with a discharger; the circulating feed opening is connected with a sieving feed passage; a circulating discharging passage is arranged above the circulating screen mesh, and is communicated with a flour milling machine feed passage; a plurality of screen discharging pipes are connected to each grading screen mesh in the grading screen mesh mechanism. The circulating impact flour milling unit is small in occupied space, low in cost, small in energy consumption, and capable of avoiding damage from large foreign impurities, realizing circulating processing and continuous discharging, avoiding the generation of pulverized materials which cannot reach size requirements, and classifying the processed materials to finished products with different grain sizes to be conveyed out.

Description

technical field [0001] The invention relates to a kind of impact crushing equipment for crushing materials, which can be used in various industries such as feed, mine, food and medicine. Background technique [0002] Crushing materials is a necessary process in many processing industries, and pulverizers are widely used in industries. Existing crushing equipment includes impact mills, hammer mills, etc. [0003] Existing hammer mills include housings, rotors with hammers, screens and motors. The material enters the machine body, the hammer rotor rotates at a high speed driven by the motor, and the crushed material meets the requirements and passes through the screen to become a finished product. The disadvantage of this kind of mill is that the discharge is not smooth, and the phenomenon of material accumulation often occurs. The part of the crushed material remaining in the mill is repeatedly crushed by the hammer, which wastes energy. In addition, due to the problem of ...

AI Technical Summary

Problems solved by technology

However, the impact mill has the following defects: 1. The impact mill is easy to enter foreign matter, causing damage inside the machine and causing damage

2. The existing impact mill can only crush but cannot control the particle size of the crushed finished product

In different industries (such as grain processing industry), sometimes finished products with different particle sizes are required, and the existing impact mill equipment cannot divide the finished products into different particle sizes and send them out

3. When the particle size of the material particles is greater than the maximum value that the impact mill can process, the impact mill is prone to damage
