As for as ball to powder ratio is concerned, if the purpose is mixing you should go for 510 ration of ball with powder. In case if you want to reduce the size or ally the powder then select high
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill amp; ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment. In present day practice, ore is

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical
#0183;#32;1. Introduction. Wet ball mill is one of the most predominantly used method for the purpose of mixing and grinding of raw materials in laboratories and industry,, .The ball mill process is very complicated process governed by many parameters, such as ball size, ball shape, ball filling, slurry loading (with respect to ball amount), powder loading with respect to the amount of total slurry
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
critical speed of the ball mill nc in powder metallurgy. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed but most mills operate at speeds between 65 and 79 percent of critical speed Rod mills speed should be limited to a maximum of 70 of critical speed and preferably should be in the 60 to 68 percent critical speed range

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of mediumhard, soft, brittle, fibrous, temperaturesensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding bowl respectively the mortar.
#0183;#32;Powder Metallurgy Lesson Objectives In this chapter we shall discuss the following: 1. roll crushing, (b) ball mill, and (c) * Critical speed is the speed above which the ball will centrifuge. Very slow speed of rotation will not carry the balls to the top, these will roll back down the drum sides.
