ball size calculation for ball mill

2) Ball milling – a ball mill with adiameterof2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.

Thesizeof theballmainly depends on the particlesizeof the material to be ground, and the diameter and speed of themillcan be considered appropriately. Formula (1-15) is an empirical formula for spherical diameter and feedsize. dmax — The maximum diameter of steelball, mm; amax — themaximum sizeof feeding granularity, mm.

Jun 25, 2018 ·Milleffective diameter = 2.23 m . 335 is a constant used for dry grinding with steelballsin themill. Actualsizeof media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximumball size, thenreduce the feedsizeby using pre-grinding operation.
