Ball Mill Working Principle Ppt

The working principle of hammer mills step by step guide a hammer mill is an essential machine in the pharmaceutical and food processing industries.

Ball mill working principle ppt. It is efficient tool for grinding many materials into fine powder. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. 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. Ball mill consist of a hollow cylindrical shell rotating about its axis.

They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel ranging from 0 010 litres for planetary ball mill mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills. Working principle operation. Definition types and working principle.

Major parameters for ball milling temperature size and number of the balls nature of the balls rotation speed 8. 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. The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example. Size reduction is done by impact as the balls drop from near the top of the shell.

A 5 x 5 ball mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all. Types of ball mills. What is ball milling. Introduction definition basic principle construction working advantages and disadvantages applications equations 4.

You can use it to crush pulverize shred grind and reduce material to suitable sizes. 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 rubber inner surface of the shell is lined with abrasion resistant materials such as manganese steel or rubber length of the mill is. A ball mill is a type of grinder used to grind materials into extremely fine powder. Even though there are many types of hammer mills the working principle is still the same.

Then discharge of ground material performed. There are two types of grinding the dry process and wet process.
