Features of jet milling equipment
Air jet crushing equipment is used for various materials that cannot be crushed at room temperature. It is widely used in various chemicals, petrochemicals, machinery, ships, automotive industries, electronics industries, clothing, coatings, printing, engineering plastics, rubber, thermoplastic materials, hot melt Ultra-fine crushing of type materials, nylon, polyester, polyethylene, polypropylene, textiles, clothing, Chinese and Western medicinal materials, food industry and other products. The inert gas shielded airflow crushing system is a dry crushing system for flammable, explosive, and easily oxidizing materials. It consists of a nitrogen source, a compressor, a silo, a crushing host, a cyclone separator, and a dust collector. The material to be crushed enters the crushing area from the silo in a closed state, and the crushed material enters the classification area with the ascending airflow. The fine particles meeting the particle size requirements enter the cyclone separator and the dust collector to collect with the airflow, and the coarse particles return to the crushing area to continue. Shattered. The filtered inert gas is returned to the compressor suction port for recycling, meeting the requirements of environmental protection, energy saving, and clean production.
The working principle of the airflow crushing equipment: compressed air is filtered and dried, and then injected into the crushing chamber at a high speed through the Laval nozzle. The animal material is repeatedly collided and rubbed at the intersection of the high-pressure airflow and crushed. The crushed coarse and fine mixture plays a role in the negative pressure fan After reaching the classification area, the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classification turbine. The materials that meet the particle size requirements are collected by the cyclone separator and dust collector through the classification wheel, and the coarse particles drop to the crushing area and continue to be crushed.
Features of jet milling equipment:
1. It is suitable for dry pulverization of various materials with Mohs hardness below 9, especially suitable for the pulverization of materials with high hardness, high purity and high added value.
2. The breakthrough of particle acceleration technology has greatly improved the crushing efficiency, reduced energy consumption, good particle shape, narrow particle size distribution and no large particles.
3. During the crushing process, the airflow temperature is reduced due to the rapid expansion of the airflow, which is especially suitable for the crushing of heat sensitive, low melting point, sugar-containing and volatile materials.
4. The crushing of materials by collision with each other is different from mechanical crushing which relies on the impact crushing of blades or hammers, etc., so the equipment is free from wear and the product is of high purity.
5. It can be used in series with a multi-stage classifier to produce products with multiple granularities at one time.
6. The equipment is compact in structure, easy to disassemble and clean, and the inner wall is smooth and has no dead corners.
7. The whole system is sealed and crushed, no dust, low noise, and the production process is clean and environmentally friendly.
8. The control system adopts program control, which is easy to operate.
9. Variable combined structure, compact structure, multi-purpose machine.
