2.When the original ball mill drive system is replaced by the variable frequency speed regulation system, the mill will surely work normally at low speed, and the normal process control will be guaranteed.The ball mill and the motor will have longer life and low maintenance.3.
Key words automatic control, ball-mill, control method, generalized predictive control.1.Introduction a ball-mill, as important item of equipment in coal prep-aration systems, is widely used in large-scale thermal power plants both at home and abroad 1.Currently, there are two major types of ball-mills using in utility boilers single inlet.
The noise problem of ball mill is a difficult problem to solve in the production process when we faced a huge negative impact to bring production work.To reduce noise hazards, through testing and analysis of the ball mill, we found a solution to their difficulties.
2.1.Process flow and control infrastructure each module at waterval concentrator wvalc employs a 7.3 m x 8.2 m egl sag mills with 2 x 5200 kw motors in primary milling duty.Two silos containing merensky and ug2 ore respectively feed the mill that operates at.
The wire rod mill of the kimitsu works, 2 the high rigidity three-roll-finishing rolling mill of the bar mill of the yawata works, 3 endless rolling in the wire rod mill of the kamaishi works, and 4 the renewal of pouring reel and its master control system of the bar mill of the muroran works.2.
Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases.Process iq is an expert in implementing control systems for sag and ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by mintek.
This improved performance is made possible by the optimization of all ball mill systems parameters, including the incorporation of a high-performance classifier, improved control systems and grinding aids.A closed-loop ball millclassifier circuit can be positioned on load cells for weighing the total mill content of media and material.
Process control.Reaction temperature reaction temperature is monitored using thermocouples and is controlled by periodic water cooling.Load in the ball mill the load in the ball mill can be monitored by load cells or by current consumption.According to the load in the mill, new material is fed automatically when the load reduces.
Mill returns tailings, z tons is the amount of material in the mill also called the mill load, d represents the clinker hardness, v is the separation function and z,dis the ball mill outflow rate.The grinding function z,dis shown in fig.2 for different values of d.It is a non monotonic function of the mill.
Usually ball mill perimeter screen number should be more than a coarse particle size.3.Appropriate feeding speed feeding speed and the size of the lumpiness of the feed, screen load and discharging speed.When the lumpiness is coarse, feeding speed should be slowed down.Otherwise, the control screen load will increase or damage.
A complementary milling and flotation advanced process control system at the platmin pilanesberg platinum mines concentrator.In proceedings of the precious metals 12 conference held at the vineyard hotel, cape town, south africa from november 12 to 13, 2012.6.
Process control is an essential part of the cement milling system.Development of an eective control strategy requires a good knowledge of the dynamics.Ball mill control strategy proposal.
Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level.The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size.
