Both of the dry and wet ball mills are composed of feeding port, discharging port, turning part, and transmission parts such as retarder, small transmission gear, motor, electronic control.Horizontal Grinding Mill Overflow Type, Gratedischarge,,The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium (e.g. steel balls, cylpeb, and pebbles) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet processing.
Read MoreThe ball mill is a typical material grinder machine which widely used in the mineral processing plant, ball mill performs well in different material conditions either wet type grinding or dry type, and to grind the ores to a fine size. Main ball mill components: cylinder, motor drive, grinding medium, shaft. The cylinder cavity is partial filling with the material to be ground and the metal grinding balls. When the large cylinderVertical roller mills: The new leader in grinding technology,Consequently, efficiency in energy used can be as much as 40% – 45% less than a wet ball mill circuit – noticed with all power going into the comminution of the ore. Smarter process control ensures consistent grinding to the correct size whilst the mill is in operation. All this is done in a dry process, reducing the oxidation of the float product.AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill,,Ball Mill Design.
