measuring load in a ball mill

What are the methods of measuring ball mill load?_cement

A load sensor is installed under the bearing of the feeding end and discharging end of the ball mill to continuously weigh the mill, so as to determine the total amount of ball medium, ore and water in the ball mill and determine the load of the mill.Its advantage is simple, the disadvantage is the detection accuracy is not high, can not

Circulating Load Calculation Formula

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load

Ball Mill Load Measurement Using Self-adaptive Feature

Sep 15, 2008· Ball mill load is the most important parameter optimized in the Ball Mill Pulverizing System (BMPS) in Thermal Power Plant. The accurate measurement of ball mill load is imperative and difficult. The approach based on self-adaptive feature extraction algorithm for noise signal and LS-SVM model is proposed to achieve this purpose.
