Nov 01, 2009· Zhang (2001) studied the fill level by measuring the energy consumption of the mill motor, but the wear of steel balls and the variation of ball load can seriously affect the power value of the mill. Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell.
For the ball mill efficient operation, it is necessary to constantly maintain the required loading level by the grinding media. It is very important to correctly and accurately measure the grinding media quantity in the mill. Measurements provided in the worked-out mill (without crushed material) by measuring the following parameters (measurements provided at three points – mill power ...
Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Products. AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
Aiming at the disadvantage of ball mill system control, a new control algorithm based on fuzzy logic control is proposed. Firstly, the dynamic characteristic of ball mill pulverizing is given. Secondly, the control method is introduced. For mill level control loop, by the fuzzy decision making, the mill fill level is represented by the out temperature and the differential pressure.

constant ball load of 28%. In the pilot scale experiments, the Magotteaux ball mill at Frank Concentrator was equipped with a Sensomag sensor for measuring the toe and shoulder angles of the slurry and ball load based on the principle of conductance and induction, respectively. The mill was configured to operate as a RoM ball mill.

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 5-m 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 ...

A method of measuring the fill level based on the vibration signal of the mill shell is researched in this paper. An accelerometer that has a large measurement range is mounted directly to the mill shell, and the vibration signals are collected off the mill shell by a data acquisition system in experiment.
