Ball grinding mill is Formed a closed system with air classifier.Coarse material will be back to ball mill to grind again, and qualified material will go to be packed by worker or packing machine. Advantage (1) It equiped with ceramic liners and grinding media is ceramic balls to keep free of iron impurity.
Energy-Saving Ball Millare generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
Grinding control strategy on the conventional milling circuit of Palabora Mining Company by B.J. du Plessis* Synopsis Automation of the conventional grinding circuits of Palabora Mining Company (PMC) required that adequate instrumentation and a control system had to be put in place, after which extensive
Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 ...
To achieve a reasonable efficiency with ball grinding mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.
Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times.
(1) Types on the Basis of Cylinder. 1. Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter, i.e. the ball mill with L ≤ 2D is short cylinder ball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3 ball mills in series.
