Fluidized bed type air flow crusher consists of air source part, feeding part, crushing part, product grading part and product collection part. Air source part of a certain pressure and flow of clean compressed air and feeding part of the solid particles provided in the crushing chamber mixed to form a gas-solid two-phase flow, generated by the nozzle of the supersonic air flow so that the solid particles collide with each other to get crushed, and then by the top of the main machine grading part of the particles to reach a certain level of fineness from the crushing chamber to separate out and the product collection part of the product collection and packaging.
High Efficiency and Low Energy Consumption: The equipment achieves exceptional crushing efficiency with minimal energy usage, ensuring cost-effectiveness and reduced environmental impact.
Minimal Wear and Durable Performance: The design minimizes wear and tear, making it suitable for processing high-hardness materials while ensuring a long operational lifespan.
Precise Particle Size Control: Offers a narrow particle size distribution and easy adjustment of particle size, meeting specific application requirements with high precision.
User-Friendly and Safe Operation: Features full enclosure for anti-contamination processing, easy operation, and stable performance, ensuring reliable and secure operation.
Wide Applicability and Versatility: Adaptable to a broad range of materials, including heat-sensitive substances, and applicable across diverse industries such as pharmaceuticals, chemicals, and food processing.
