TheBond’s Ball-MillWork Index is a measure of the resistance of the material to grinding in aball mill. This Index is widely used in the industry for comparing the resistance of different materials toball milling, for estimating the energy required for grinding and forball millscale-up.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
The circular vibrating screen is a vibrating screen with high efficiency and it advantages include stable structure, strong exciting force, high efficiency, low vibrating noise, durability, handy maintenance and safe operation.
Ball milldesign requires aBond workindex, BWi, forball millsat the correct passing size;SAG milldesign requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
The optimum number ofgrinding ballsis 285. However, theball diametersvary due to wear. Therefore, the totalball numbershould be adjusted from time to time to ensure a total mass of 20.125 grams. The grinding jar of theBond Index Ball Millmeasures 12″ x 12″ and has well-rounded corners.

A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls.
HoweverBond’sThirdLawcan be reasonably applied to the range in whichball/rodmillsoperate in. In spite of the empirical basis ofBond’stheory, it is the most widely used method for the sizing ofball/rodmillsand has become more likely a standard.

• Based onBond's Crushing Law, the power requiredto crush a certain material will change by % if the diameter of the product is made smaller by 50%. • In crushing a certain ore, the feed is such 80% is less than 50.8 mm in size and the product size is such that 80% is less than 6.35 mm.
