MILLCOM is widely used for the efficient operation and increased production of various types of grinding machines; from small ball mills for fine ceramics to huge grinders for cement industry.Maximum grinding efficiency can be automatically maintained by installing ball mills and other mills with microphones (Electronic Ears) for the automatic control of raw material feed rates.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Innovative sensor systems, closed-loop controls and databases. With SmartFill, the 'electronic ear', KIMA has set new patterns regarding the precision and reliability of measuring the fill level of ball mills. Based on the great results received with the SmartFill system, KIMA has developed its predictive expert system SmartControl.

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

Dec 19, 2019· The ball mill can Reduce the ball mill noise below the allowable standard. (3) The ball mill uses a rubber liner instead of a manganese steel liner. The noise level can be reduced by 9dB (A), and the frequency spectrum characteristics of the ball mill are also changed from high frequency to low frequency. Ball mill design soundproof room.

The Ball Mill System (BMS) is a strongly coupled MIMO system,in order to implement a long-term 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 S7-400PLCS7-200PLC,the PROFIBUS DP protocol and MPI protocol are both employed to setup a DCS .

LEADING TECHNOLOGY IN BALL MILL CONTROL. With MillMaster KIMA Process Control offers the most robust, open and easy to handle Advanced Control System in the Cement Industry. Since 1996 this 'Auto-Pilot' system was installed in hundreds of cement plants to operate mills fully autonomously.

The Control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was - incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill .

Mar 14, 2014· Re: Coal Mill Level Monitoring Sytem for a Roller Mill 03/14/2014 10:46 AM I worked on a Milltronics ball mill control system years ago and for what I recall sound pressure was only one process variable used to measure mill load.

Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation process.How to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health ...

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

With more than 100 years of experience in ball mill technology, 's ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.
