The Planetary Ball Mill PM 100 is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch. The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short ...
Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).
In dry crushing of limestone, lumps of 50 mm size have their size reduced to 10 mm. Estimate the theoretical power required for a feed rate of 20 tph. Solution: According to Bond's law, the power is:) 0.05 1 0.01 1.(3600 36 20000 12.74 P = 14100 W (19.2 hp) Since dry operation is effected, this figure has to be multiplied by 4/3 to give a power
