Vertical Roller Mill Parameter Selection

The production capacity of the vertical roller mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting.

There are many factors affecting the production capacity of the vertical roller mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of grinding (product size), the uniformity of the feeding material, and the portion of loaded, , and the mill structure (the mill barrel length, diameter ratio, the number of bins, the shape of the partition plate and the lining plate).

It is difficult to theoretically determine the productivity of the mill. The grinding mill's production capacity is generally calculated based on the newly generated powder ore of less than 0.074 mm (-200 mesh).

Effective volume of vertical roller mill, m3;
Material less than 0.074mm in product accounts for the percentage of total material;
Material less than 0.074mm in ore feeding accounts for 0.074mm in the percentage of the total material;
Unit productivity calculated according to the new generation grade (0.074mm), t/(m3.h).

The values of q'm are determined by experiments or are calibrated in production with similar ore physical properties and the same equipment and working conditions. When there is no test data and production calibration value, it can be calculated.
