Vertical roller mill replaces stone powder with limestone powder for burdening modification. By adjusting the height of the retaining ring of vertical roller mill, optimizing the parameters, modifying the form and structure of the wind ring, optimizing the ventilation area and wind speed, the vertical grinding system can adapt to the change of the particle size distribution of the raw material.
The main parameters including material properties, disc diameter, grinding speed, roll diameter, roller number, design production, feed size, product fineness, grinding, grinding, water moisture into the air, grinding grinding grinding, air temperature, air outlet air temperature, material thickness and single stick pressure roller.
The temperature of the cement mill is too high, including fan motor heating and bearing temperature too high, and so on. First, we must find out the reason why the temperature rises, then solve the problem.
The appearance of vertical roller mill makes it possible to finish superfine grinding, classification and conveying at one time. It has become the equipment of superfine milling industry, and is widely used in chemical, metallurgical, non-metallic minerals and other industries.
