What is the number of the vertical roller mill classifier revolutions

In the previous article called Control and adjustment of vertical roller mill classifier, we learned how to control and adjust Vertical Roller Mill's classifier. So, is there any rotation limit for vertical roller mill's classifier? How should we adjust its rotation speed?
 
The classifier machine is one of the main components of vertical grinding mill (this article called The components and functions of vertical roller mill introduces the structure of vertical roller mill in detail). The grinding chamber is used for powder classification and grinding again. After the powder in the grinding chamber is blown away by the fan, it must pass through the classifier area of ​​the vertical grinding mill. The classifier is a blade rotor that rotates evenly clockwise or counterclockwise around the center axis of the vertical roller mill, and its shape is similar to a fan. Its rotation speed directly determines the fineness and output of the powder milled by vertical roller mill. When the powder passes through the classifier again, the coarse powder is too slow, and the rotating blade of the classifier is knocked down to the grinding chamber, which is ground into a fine powder again so that it can pass through the classifier chamber.

Method of calculating cement ball mill capacity

Cement ball mill  is commonly used crushing equipment in the industry ,the statistics on the output of the ball mill in actual production is an important basis for the report-type statistics of the production workshop. The data is mainly the statistics of the production of different shifts and the output of the ball mill, and we usually calculate the capacity of the mill. The basic methods are: the measuring method, the feeding weight measurement method, and the estimation of the output per ton of grinding body. Below, Dawning introduces you to the calculation of the specific yield of different methods. 1. Volume method The bin method is one of the easiest methods for calculating the actual output of the ball mill. For the actual measurement, we take a simple weight measurement as an example, weigh a small iron drum of 1000 ml of water, and then we will Put the cement or raw material into it, tap it, smooth it, weigh it, then pour it out, fill it with water and weigh it again, then...
