1.Brief Introduction
Jet mill is a kind of equipment that uses high-speed airflow to achieve dry ultra-fine grinding of materials. Most common ones on the market are fluidized bed type and disc type. The filtered and dried compressed air is accelerated through the Laval nozzle and injected into the crushing zone at supersonic speed. The materials are fluidized and accelerated in the supersonic jet, and impact and collide with each other at the intersection formed by multiple nozzles to be crushed. The crushed material rises along the air flow to the classification area and is classified in time. The coarse material falls along the cylinder wall to the crushing area to continue crushing. The qualified fine powder is collected by subsequent equipment.
2.Performance Characteristics
The crushed product has uniform particle size and low fineness, and the finest dry method can reach d50:0.5um.
Equipped with a turbine-type classification device, the materials can be classified in a timely manner without over-crushing.
Using compressed gas as power and low-temperature crushing. It is suitable for crushing heat-sensitive and low-melting point materials.
No impurities are brought into the crushing process, and the product purity is high.
There are no moving parts in the crushing area, so the mechanical wear is small and the cost of wearing parts is low.
Compact structure, small footprint, easy to disassemble and maintain.
For flammable and explosive materials, inert gas can be used as a protective medium to achieve closed-circuit crushing, and the inert gas can be recycled.
Full protection lined with non-metallic materials can realize ultra-pure production of new energy lithium battery materials and sodium battery materials.
3.Application Fields
