Features of disc type air jet mill equipment:
1. It is suitable for ultra-fine crushing of dry powder materials, with large impact particle size, which can reach above Mach 2.5, and general materials can be easily crushed to 1-10 microns.
2. Compared with the fluidized bed jet mill, it has a good crushing effect on viscous materials, and the crushing process will not cause the phenomenon of blockage and pulverization.
3. No temperature rise, pulverization process The temperature of the pulverization process is reduced due to the compressed gas nozzle, and there is no mechanical friction process, so the pulverization process does not increase the temperature.
4. Simple equipment, convenient cleaning, convenient operation and maintenance, small footprint, low noise and no vibration.
5. Low investment. According to customer requirements, unnecessary equipment such as dust collectors, fans, and control boxes can be taken.
Working principle of disc jet mill
Compressed gas is passed through the feeding ejector, and the crushed raw material is brought into the crushing chamber. It is sprayed onto the crushing wall in a tangential manner by the high-speed air flow sprayed from multiple nozzles to achieve the friction crushing effect. By adjusting the longitudinal depth of the crushing chamber and the crushing pressure, Or feed speed to control the fineness of crushing. Compared with the fluidized bed jet mill, the controllability of the crushing fineness is poor, but it has a good crushing effect for materials with viscosity.
