Ball Mill Operating Parameters

Ball mill operation is often regarded as something of a mystery for several reasons Ball milling is not an art it’s just physics The first problem will ball mills is that we cannot see what is occurring in the mill The other problem is that many of the independent variables

MILL is the ball milling model that is based on standard Austin’s models Eqns 14 and and takes into consideration the breakage parameters as does the MolyCop It is mentioned that the MILL model does not take into consideration the operating conditions eg mill diameter ball filling volume and mill speed and a different unit model

Several types of ball mill exist They differ to an extent in their operating principle They also differ in their maximum capacity of the milling vessel ranging from 0010 litres for planetary ball mill mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills

A ball mill is a type of grinder used to grind materials Major parameters for ball milling Temperature Size and Number of the balls Nature of the balls Rotation speed 8 Types of Ball Mills

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 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

Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration Figure 2 shows that there is no linear relation between
