1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain size hardness density temperature and humidity the degree of

The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind A major practical indication of mill loading is the sound made by the mill A properly loaded mill will have a deep rhythmic roar while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silentView Details
The second approach to ball diameter calibration is the socalled absolute method In absolute measurement temperature is a first order error that must be held at 68 °F 20 °C exactly or any variations must be compensated for A micrometer or threaddriven measuring machine is an example of the absolute conceptView Details
The mill is 12 in x 12 in with rounded corners and a smooth living except for a 4 in x 8 in hand hole door for charging It has a revolution counter and runs at 70 rpm The grinding charge consists of 285 iron balls weighing 20 125 gramsView Details
Standard Bond ball mill grindability tests and calibrated Mod Bonds using a closing screen of 270 mesh 53 microns classified most samples as medium to moderately hard and averaged 153 kWht Mod Bond only The SPT lockedcycle high pressure indices HPi ranged from 146 kWht to 184 kWht averaging 164 kWhtView Details
Ball mill is mainly used for grinding in mining metallic minerals and nonmetallic minerals cement refractories chemical power plant aluminum building material glass ceramic steel slag and fly ash follows more crushing and less grinding principle to save energy The feed size to ball mill shall be smaller than 25mm the output size can be adjusted by revising steel balls ratioView Details
