Grinding in Ball Mills: Modeling and Process Control

Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements. One company believes that if a closed circuit process is used, the length of the mill should be reduced to 11m. In fact, a senior cement expert in the survey introduced that in the 1980s, developed countries stopped talking about the opening and closing of ball mills and turned to closed-circuit processes.

circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of ‘critical size’ material in the circuit. SAG (semi-autogenous) milling circuit is described with the emphasis on the process control systems employed. The history of the circuit (process) controller is then discussed briefly to illustrate the differences between historical and new techniques. The evolutions of the control philosophy, as well as the financial benefits, are described ...

Ball mill is the cement crushing equipment in the cement plant. Compared with open- circuit ball mill, the closed-circuit ball mill has high efficiency, high output, low cement temperature, and good comprehensive benefit. It is the best choice for a cement plant. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

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. F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
