Multi-stage combined type efficient crushing cutter set for flour mill

Abstract

The invention discloses a multi-stage combined type efficient crushing cutter set for a flour mill, and belongs to the field of flour milling machinery. The multi-stage combined type efficient crushing cutter set comprises a first-stage crushing cutter set body, a second-stage crushing cutter set body and a third-stage crushing cutter set body which are sequentially and coaxially arranged, the first-stage crushing cutter set body and the second-stage crushing cutter set body are oppositely and fixedly arranged, and a sieve tray is arranged between the first-stage crushing cutter set body and the second-stage crushing cutter set body. And the rotation directions of the third-stage crushing cutter group and the second-stage crushing cutter group are opposite. According to the pulverizer, efficient pulverizing of materials is achieved through cooperation of the multiple stages of pulverizing cutter sets, the first-stage pulverizing cutter set pulverizes the materials and then filters the materials through the sieve tray, fine particles are further pulverized through the second-stage pulverizing cutter set and the third-stage pulverizing cutter set, the material pulverizing efficiency can be higher, the materials are pulverized more densely, and the energy consumption of the pulverizer is lower; moreover, after the sieve tray is used for filtering, the second-level crushing cutter set and the third-level crushing cutter set only need to crush fine particles, abrasion to crushing blades is smaller, and the service life of the second-level crushing cutter set and the service life of the third-level crushing cutter set are longer.

Description

technical field [0001] The invention relates to a pulverizing knife set of a pulverizer, more specifically, to a multi-stage combined high-efficiency pulverizing knife set for a pulverizer. Background technique [0002] With the widespread use of plastic products, the harm of waste plastics to the environment and human health has become a serious problem that people have to face. Plastic recycling technology has also become the main technical means to reduce the harm of waste plastics. At present, most plastics need to be pulverized and pulverized in the recycling process, that is, waste plastics are first broken into small pieces, and then the broken small pieces of plastic are pulverized into powder to realize plastic recycling. [0003] The pulverizer is the main equipment for crushing small pieces of plastic into powdery particles. It uses the internal high-speed rotating cutter head to crush the material. It can also be used for crushing and recycling some other composi...

AI Technical Summary

Problems solved by technology

Both the feeding of bulk materials and the discharging of powder materials of the mill are completed by the suction of the fan, so a larger fan is required to meet the suction force, resulting in a larger power required by the entire milling system. Not conducive to energy saving of equipment
