overflow ball mill drawing

Ball Mill Motor Power Draw Sizing and Design Formula

19-10-2015  The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

An overfilling indicator for wet overflow ball mills ...

01-09-2016  For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw; rather more often the opposite. This is attributed to the fact that the slurry pool on the opposite side of the rising ball media would counter the torque required to rotate the mill shell and lift the ball media, leading to a decreased mill power draw.

Ball Mill Operation -Grinding Circuit Startup Shutdown ...

01-02-2016  The ball mill must be run to draw maximum power at all times. The operator must manually measure the cyclone overflow and underflow densities regularly. An increase in overflow density is indicative of softer ore and will soon be accompanied by a lowering of power draw at the mill and a change of sound indicating that the mill is becoming under loaded.

Overflow VS Grate Discharge Ball or Mill - Why Retrofit

24-06-2015  The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.

Modelling the influence on power draw of the slurry phase ...

01-04-2016  In overflow ball mills this slurry toe extend up to at least the point where it can overflow out of the discharge trunnion. As flow requires a gradient, the slurry toe position in an overflow ball mill will actually be higher than the lowest point of the discharge trunnion and as flow increases the slurry toe will become progressively higher.

Ball Mill Working Principle And Main Parts

The most widely used in the production of a variety of ores are wet overflow ball mill and wet grate ball mill. Aside from common ball mills there is a second type of ball mill called planetary ball mill Planetary ball mills and The grinding balls. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes.

Model-based procedure for scale-up of wet, overflow ball ...

Bond's method for ball mill scale-up only gives the mill power draw for a given duty. This method is incompatible with computer modelling and simulation techniques. It might not be applicable for the design of fine grinding ball mills and ball mills preceded by autogenous and semi-autogenous grinding mills. Model-based ball mill scale-up methods have not been validated using a wide range of ...
