For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated Using G K * D Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM

To compute for shaft power, two essential parameters are needed and these parameters are Mill Capacity (Q) and Specific Power of Mill (E). The formula for calculating shaft power: P = QE. Where: P = Shaft Power Q = Mill Capacity E = Specific Power of Mill. Let's solve an example; Find the shaft power when the mill capacity is 20 and the ...

Ball Mill Motor Capacity Power Equatioon. Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. ...

A somewhat simpler equation is given below for use between the following limits; 20< P< 50,000 microns, and
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

commercial ball mill (Mitui Miike Attritor, model MA1D) is 300 rev min1. Figure 2 shows the torque acting on the agitating media vs. the angular velocity for various testing temperatures between 30°C and 250°C. We can see that the torque increase can be fairly well expressed by a power law: P = ARn Equation 1 Motor Timer (hrs, min, sec)

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communications).

Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed. The effects of changes to the properties of the charge (ball fraction ...

Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

Differentiation of KW with respect to V in equation (2) shows that power draw increases with charge level to peak at about Vp = .58. For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2.
