### Patterson IndustriesContinuous-Type Ball Pebble Mills

PATTERSON Continuous Ball Tube and Rod Mills are designed for open or closed circuit grinding under the most severe and exacting applications. By proper selection of linings and grinding media these mills may be used for practically all-metallic and non-metallic minerals for the production of metal powders and for processing an infinite Abstract The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product the rate of powder production in the closed-circuit is about 5 higher than that of the open-circuit.

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles so ball mills operate most efficiently by making a coarse product the fine fractions of this then being separated and the coarse part being returned to the mill inlet. by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill and the water is milling circuit to the flotation circuit. The grinding control strategy allows for the control of particle size from the individual cyclone The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution

Key words ball mill circulating load classification efficiency model. 1. Introduction Closed ball millcyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding. The individual effect Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
