dec 04, 2020 the laboratory procedure for running a bond ball mill work index test requires that the operator choose a closing screen sieve size. the instruction is to choose a ball mills usually operate at 65% to 75% of the critical speed. the critical speed is calculated as under 2.1.3 work index: work index is defined as the gross energy required in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80% of the undersize passes through 100- screenthe bonds ball-mill work index is a measure of the resistance of the material to grinding in a ball mill. this index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill bond test wis rod mill: ball mill: 9.5 kwht.8 kwht bond standard circuit work index: assume the rod mill work index of 9.5 applies from the actual rod mill feed sizeof 19,300 to a rod
It is measured according to the principle that to calculate the grinding work index based on output of each revolution of the mill after the material is ground to a balanced state by the specified mill. this ball mill, also called mill for measuring bond work index, is a key device for measuring grinding work index.magdalinovic and cumpujerovic showed the fact that an approximate value of the ball-mill work index can be determined by doing just two grinding tests. chongbo and bingchen studied away to simulate the calculation method of the bond rod-mill work index.planetary ball mill for rapid fine crushing of soft, hard, brittle and fibrous material to end fineness quick and easy to clean rapid fine crushing easy exchange of grinding jars and balls grinding jars and balls made from a wide range of materials available grinding jar volume up to progr. control end fineness ce-certified planetary ball mills for fine grinding overview lab roll mill is a kind of equipment used for ultra-fine grinding and mixing for laboratory and small batch production. the machine is preferred equipment for scientific research, education, experiment and production due to its advantages such as elegant and fashion design, compact structure, easy operation, high efficiency, and uniform granularity.
