Expert System Control Strategy Grinding is a process by which ore is comminuted to better liberate and hence recover the valuable mineral. All else being equal the greater the ore feed rate the coarser the grinding product and the greater the metal losses. A concentrator must therefore balance the production rate with the metal losses.

The grinding is performed by means of hammers rotating quickly in a chamber lined with wearresistant lining. The hammers hit the ground material crushing it against the lining. Further comminution is achieved by attrition of the particles against each other.
The MillStar Advanced Control System a product from Mintek has a comprehensive suite of control strategies that can be applied to provide an innovative control solution for almost any milling circuit configuration. The main goals are Stabilise the mill feed. Control product quality to the downstream processes.
Engineering and equipment are provided including electrical controls classifying/grinding mill monitoring for safety and maintenance sensors and a PLC/PanelViewbased automation system. These control and automation systems can also include formulation and setpoint data storage live data trending and historical data collection.
Once our Smart Mill Control System is operating the algorithm will maximize the performance of your tube mill by operating it at the best possible grinding point. This will not only stabilize but also optimize your grinding process Up to higher throughput Up to 9 lower energy consumption
A variation (in some pin mills) is the counterrotating tworotor assembly spinning in opposite directions. This configuration works on the principle of higher tip speed (impact actions) for fine grinds. Attrition or Disc Mills are milling machines arranged with one rotating and one stationary disc. The grinding surface has machined teeth.
The level of a grinding charge in a grinding mill is monitored by comparing signals which are generated by means of two sensors which are located on opposed sides of an impact point of the material in the mill. A signal produced in the comparison step may be used to control the feeding of material to the mill.

Combine ABB s variablespeed drive system with advanced process control ABB Ability™ Expert Optimizer for grinding to provide maximum mill control. It can be applied to new or existing AG SAG and ball mills powered by either ringgeared mill drives (RMD) or gearless mill drives (GMD).
Our system effectively mitigates the number of variables in the control formula of your mill to optimise the performance of your operation. A safer work environment Worker safety is paramount for any business and our PERI AutoCharge Mill Grinding Ball Charging System will help protect your employers by minimising or eliminating the frequent
Pressure and temperature measuring system In order to understand the processes which occur during grinding with ball mills ( chemical reactions phase changes) it is helpful to record the most important thermodynamic parameters pressure and temperature. Planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input.
Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution where optimal levels for the enrichment particles sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been subjected to extensive
The system continuously monitors the equipment condition and allows advanced monitoring strategies such as remote expert support to ensure maximum mill availability. The modular solution proactively detects anomalies using diagnostic data to determine instrument health and detect installation problems before they cause downtime.
1.. IntroductionGrinding mill circuits are the most energy and cost intensive unit processes in the mineral processing industry and therefore the study of the control systems for grinding circuits remains important (Ramasamy et al. 2005 Wills and NapierMunn 2006).Grinding circuit control objectives range from maintaining system stability to achieving maximum economic benefit.
grinding mill plants. Our special design of the ENGSKO millstones is a result of practical experience gained during more than 100 years of production. They are produced in sizes from 250 mm to 1500 mm and composed of highquality natural materials such as flint and emery. The rest is our secret ..
