Advantage of Daswell grinding roller mill
- Large output: When the calcium carbonate is crushed, the fineness is D97, and the output can reach more than 1 ton per hour at 10μm.
- Built-in grading system, the product can be adjusted arbitrarily between 5-45 microns.
- Environmental protection and pollution-free. The whole set of equipment adopts negative pressure production and high-efficiency off-line dust collector, and the dust collection efficiency is as high as 99.9%. The operation is stable and there is no dust leakage problem.
- In addition, the main engine and the fan are respectively equipped with a silencing room and a silencer to reduce production noise.
- The control cabinet is installed with automatic control. Avoid human factors, ensure the stability of product quality and extend the service life of the equipment. Reduce operators and reduce production costs.
