Closed cycle cryogenic pulverizer
The closed-circuit low-temperature pulverizer is composed of air source part, feeding part, pulverizing part, product classification part, product collection and air source circulation part. The clean compressed air with a certain pressure and flow provided by the air source part and the solid particles provided by the feeding part are mixed in the pulverizing chamber to form a gas-solid two-phase flow, and the supersonic airflow generated by the nozzle makes the solid particles collide with each other to obtain pulverization. The grading part at the top of the main machine separates the particles with a certain fineness from the crushing chamber, and the product collection part collects and packs the products.

It has a wide range of applications, and can crush heat-sensitive materials, the equipment runs smoothly, and the operation is safe and reliable.
The closed-circuit low-temperature pulverizer is the latest generation of ultra-fine airflow pulverizing equipment. It integrates the international advanced multi-nozzle technology, fluidized bed technology and horizontal classification technology, and realizes the diversification of the flow field, fluidization of material layers, and classification. The combined technical system of horizontal and mechatronics is the development direction of jet mill. This machine can not only produce ultrafine powder, but also has the advantages of narrow particle size distribution, high homogeneity, easy control of particle shape, good product dispersibility, no abrasion and pollution of grinding body, etc. It can be widely used in pharmaceutical, chemical, metallurgy, Mining, energy, electronics, medicine, pesticides, plastics, paper, pigment coatings, dyes, abrasives, food, cosmetics and other industries, as well as some special materials. Such as: ultra-fine grinding of high-purity powder products such as polymer materials, advanced electromagnetic materials, magnetic materials, semiconductor materials, fine chemical powder materials, catalysts, reagents and chemicals, propellants, etc.
The machine is designed according to the "GMP" standard, and the whole machine is made of 304 stainless steel.
After repeated tests by the environmental protection department, the amount of dust discharged and prevented is much lower than the dust emission standard stipulated by the national environmental protection department. The entire production process is automatically controlled by the control cabinet. The control cabinet supplies the entire production motor (excluding the gas source and electricity), and can also control parameter adjustment, automatic start and stop, automatic protection, fault alarm and automatic shutdown. Ensure the safe operation of equipment and the stability of product quality.
