Working Principle of Horizontal Airflow Pulverizer:
After being filtered and dried, compressed air is ejected at high speed into the crushing chamber through a Laval nozzle, driving the material to repeatedly collide and rub at the intersection of high-pressure airflow for pulverization. The resulting mixture of coarse and fine particles is transported to the classification zone under the action of a negative pressure fan. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. Materials meeting the particle size requirements pass through the classification wheel and enter the cyclone separator and dust collector for collection, while coarse particles descend to the crushing zone for further pulverization.
Features of Horizontal Airflow Pulverizer Equipment:
● Suitable for dry grinding of various materials with a Mohs hardness below 9, especially for grinding high-hardness, high-purity, and high-value-added materials.
● Breakthroughs in particle acceleration technology have significantly improved crushing efficiency, reduced energy consumption, minimized over-crushing with good particle shape, achieved narrow particle size distribution without large particles, and allowed for arbitrary adjustment of product particle size D97 between 2 and 75 microns.
● During the crushing process, the rapid expansion of the airflow causes a decrease in temperature, making it particularly suitable for crushing heat-sensitive, low-melting-point, sugar-containing, and volatile materials.
● Materials are crushed through mutual collision, which differs from mechanical crushing that relies on the impact of blades or hammers on the materials. As a result, the equipment experiences no wear, and the product has high purity.
● Can be used in series with multi-stage classifiers to produce products in multiple particle size ranges in a single process.
● The equipment has a compact structure, making disassembly and cleaning convenient, with a smooth inner wall and no dead corners.
● The entire system operates with enclosed crushing, no dust, low noise, and the production process is clean and environmentally friendly.
● The control system adopts program control, making it easy to operate.
● Capable of mixing and crushing multiple materials; features a variable combination structure, compact design, and multi-functionality in a single machine.
