The name "ultrafine airflow pulverizer" means a large pulverizer that uses airflow for ultrafine pulverization. It is a complete set of pulverization system consisting of an airflow pulverizer, a cyclone separator, a dust collector, and an induced draft fan. The process is to filter and dry the compressed air, and then spray it into the crushing chamber at high speed through a Laval nozzle. After being sprayed by multiple high-pressure airflows, it forms an intersection where the material is repeatedly collided, rubbed, and sheared to be crushed. The crushed material moves to the classification zone with the upward airflow under the suction force of the fan. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, and the fine particles that meet the particle size requirements are collected by the cyclone separator through the classification wheel, while the coarse particles that do not meet the particle size requirements are continuously crushed in the crushing zone.
The ultrafine airflow pulverizer is a device that uses high-speed airflow to achieve ultrafine pulverization of materials. It consists of a pulverization nozzle, a grading rotor, a spiral feeder, etc. The material enters the pulverization chamber through the spiral feeder, and the pressurized air is sprayed at high speed into the pulverization chamber through a specially configured supersonic nozzle. The material accelerates in the supersonic nozzle jet and repeatedly impacts and collides at the nozzle intersection to achieve pulverization. The ultrafine airflow pulverizer is mainly suitable for the pulverization mechanism and has the characteristics of wide applicability and high fineness of finished products. Typical materials include superhard diamonds, silicon carbide, metal powders, etc. High purity requirements include ceramic pigments, pharmaceuticals, biochemistry, etc. Low temperature requirements include pharmaceuticals PVC。 By changing the general air in the gas source to inert gases such as nitrogen and carbon dioxide, this machine can become an inert gas protection equipment, suitable for crushing and grading materials that are flammable, explosive, and prone to oxidation.
Main performance characteristics of ultrafine airflow crusher:
1. Equipped with a vertical grading device, the product particle size D97:8-150 microns can be adjusted, with good particle shape and narrow particle size distribution. Can be used in series with multi-stage classifiers to produce products of multiple particle sizes at once.
2. The equipment is easy to disassemble and clean, with smooth inner walls. The entire system of the ultrafine airflow crusher is sealed for crushing, with less dust, low noise, and a clean and environmentally friendly production process.
3. Mastering the system through programming, easy to operate.
4. The entire system operates in a closed environment without generating dust pollution, with low noise, and a particularly clean and environmentally friendly production process.
Ultra fine airflow pulverizers are widely used in industries such as chemical, mining, abrasive, refractory materials, battery materials, metallurgy, building materials, pharmaceuticals, ceramics, food, pesticides, feed, new materials, environmental protection, and various dry classification materials for ultra-fine crushing, dispersion, and particle shaping.
