2015-6-4 The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol

ContactEffect of ball load and size distribution on grinding and. Dec 01, 2015 An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multi-compartment ball mill

Contact1976-5-1 The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si = axαi ( Q ( z ), where Q ( z) is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2.

ContactThe mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

ContactThe effect of ball size on the energy efficiency of . 1999-11-1 Because the high-pressure roll mill is more efficient at lower energy inputs and the ball mill is more efficient at higher energy inputs, the greatest potential for energy savings should come from using the two different comminution modes in tandem or in series as a hybrid grinding circuit.
