Ball mill A typical type of fine grinder is the ball millA slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls Ball mills normally operate with an approximate ball charge of 30.
MILL POWER FOR CONICAL (HARDINGE) TYPE BALL MILLS L.G. AUSTIN§, W. HILTONt and B. HALLt § Mineral Engineering Department, The Pennsylvania State University University Park, PA 16802, USA t NEI International Combustion, Derby, UK (Received 6 June 1991; accepted 2 August 1991) ABSTRACT The equations proposed previously by Austin, which allow for the presence of conical end …
1. Short-cylinder ball mill: The length (L) of the cylinder is less than twice the diameter (D) of the cylinder, that is, the ball mill with L ≤ 2D is a short-cylinder ball mill. Single-bin structure ball mill, which is mainly used for coarse grinding or primary grinding, has high efficiency. 2. Medium-long cylinder ball mill, that is L = 3D. 3.
Ball Mill Continuous Ball Mills Manufacturer from . Ball mill introduction. The ball mill is a key equipment for grinding materials, widely used in powder making production line such as cement, silicate sand, new type building material, refractory material, fertilizer, ore dressing of ferrous metal and non ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with ...
Grid Type Ball Mill principle The main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in …
The ore discharge of overflow type ball mill mainly depends on the pulp itself high over the lower edge of the hollow shaft bushing. 2. Performance and application differences between grid type ball mill and overflow type ball mill. Compared with the overflow type ball mill, the ore discharge of grid type ball mill is low-level forced discharge.
Overflow type ball mill is used to grind materials in wet condition. Compared with dry process ball mill, the biggest difference is that its end cover is cone shaped. On the end cover there is only one wave lining plate. The overflow type ball mill of Machinery is with high chrome lining plates, which is wearable. It has ferrous of low noise ...
