The Ball Mill System (BMS) is a strongly coupled MIMO system,in order to implement a longterm automatic operation of the BMS effectively,and improve the automation level and efficiency, the paper present the overall design of the system,the control system is composed of Siemens SIMATIC S7400PLCS7200PLC,the PROFIBUS DP protocol and MPI protocol are both employed to setup a DCS .

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

Also known as taper degree end mills, these end mills are angled from anywhere between 1/2° and 45° for machining angled slots in dies and molds. Ball End Mill Sets Good for rounded slots, sloping cuts, and contours, ball end mills have a rounded cutting edge.

So direct measurement must be taken for calculation of mill load. A direct measurement of the load entails the crash stopping of the ball mill under load whilst the mill is running under steady state conditions. Before taking measurement steady state conditions were verified by the plant staff, then the

Ball Mill Level Measurement. The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axise drum of the ball mill Pic is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.

MEASUREMENT POINT BALL MILL DRIVES, LOADED, OVERALL VIBRATION, SEPTEMBER 1A 1B • Above is a plot of the overall vibration levels at both the 1A 1B ball mills when loaded. • Note how levels at 1A ball mill are higher than that at 1B ball mill for nearly every measurement.

A cheaper method for mill charge measurement has been developed at SINTEF, its practical application being described in this paper. The mill load of the industrial ball mill investigated was previously controlled by measuring the power consumption of the mill motor, necessitating operating far from the range of optimal mill filling.

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Measurement of the liner wear in the mill of an ore dressing plant is one of the critical parameters in the context of mill downtime and production performance. The total downtime cost during measurement can be reduced by a significant fraction by using appropriate measurement devices.

AbstractComparison between anticipated and measured mean residence time (MRT) along with analysis of the shape of residence time distribution (RTD) curves provides the most useful and valid information about mixing properties within a ball mill operating at industrial scale. In this work, the RTD measurements were carried out for a primary ball mill in closed circuit with hydrocyclones at two ...

Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
