Metallurgical ContentTube Mill CapacityPebble Mill CapacityPEBBLE MILL LINERSPEBBLE MILL GRINDING MEDIA Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
Jun 28, 2017· The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type.
Ball-Tube Mills This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it. Impact Mills Grinding Action is carried out by aseries of hinged or fixed hammers revolving in an

Tube Mill Internal. The tube mill internals of cement manufacturing industry is composed of the grinding media, shell liners and the diaphragm. The change in impact condition may result in either spalling or hardening of the grinding media which in turn decrease the shelf life, increase the operating cost and increase the downtime.
Tube-ball mill is another dominant type of coal mill apart from Vertical Spindle mill in industry. Compared with the Vertical Spindle mills, Tube-ball mills have a much higher grinding capacity. However, there are fewer literatures found in studying Tube-ball mill operation compared with the Vertical Spindle mill.
