During shaking process. next, student should make sure that the left over sand in each sieve is transferred to the container use in weighing process. other than that, use soft bristle to clean the screen and every weighing process, clean the area of the digital scale balance to get the accurate value (chemical engineering department, 2016). screen analysis is the methods of size.
The operating principle of the ball mill consists of following steps. in a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed.
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.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. ball 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.

The working principle of ball mill and rod mill machine is similar, too. that is, the cylinder drives the movement of the grinding medium (lifting the grinding medium to a certain height then dropping). under the action of centrifugal force and friction, the material is impacted and ground to required size, so as to realize the operation of.
The ball mill consists of a metal cylinder and a ball. the working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
