A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
Ball mills are horizontal cylindrical shaped equipment that finds application in grinding hard minerals to the form of fine powder. The grinding operation is achieved here through rotation of cylinder with steel grinding balls/ceramic balls that causes balls to fall back
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding
Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel,Stainless steel or stone Inner surface of the shell is lined with abrasion resistant materials such as Manganese,Steel or stone Length of the mill is approximately equal to its diameter Balls occupy about
The Hardinge Ball Mill consists of three sections. After the usual type of trunnion bearing the mill consists of a short conical section showing a sharp drop from feed entrance to maximum mill radius. A cylindrical section of varying length then follows and toward the discharge end connects with a comparatively long and conical section sloping, at considerably less pitch than at the feed end
It has been found, by comparing the operation of Conical Mills with cylindrical tube mills in the grinding of ore and limestone, that with the same ball load in both types of mills, the cylindrical mill will consume about 60 per cent, more power for the same work as will the Conical Mill. Likewise, in comparison with a cylindrical tube mill, taking approximately the same power for operation
Cylindrical Ball Mills. The only cylindrical ball mills in common use are those of the grate discharge type, the most important being the Marcy and the Allis-Chalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semi-steel. The hollow trunnions at each end run in self-aligning bearings and are fitted
The cylindrical ball mills is key equipment for re-crushing materials after being primarily crushed. Ball mills have been widely used in a wide range of materials such as cement, silicate, new type building materials, fireproofing, stone fertilizer, black and non-ferrous metal and glass ceramics. Ball mills can realize dry type or wet type grinding for all kinds of ores and other grindable
