Objectives. At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding. Compare and contrast different type of equipment and their components used for grinding. Identify key variables for process control. Design features of grinding equipment (SAG, BALL and ROD MILLS)
The operating data for a ball mill is summarized: Mill dimensions (inside liners) Mill speed Pulp density Total solids exiting mill Solids (ore) specific gravity Steel ball charge Density of steel ball Steel void space (diameter) by 25 rpm = = = = 84% solids 40 tph (dry) 43% t/m³ 39% (a) Express the mill speed as a percentage of the critical speed.
size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 monosizes namely 8 mm + mm, 4 mm + mm and2 mm + mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium ( steel balls, cylpeb, and pebbles) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet processing.
ball mill is to be operated with a new feed solids rate of 220 tph (specific gravity ). The mill is to be in regular closed circuit with hydrocyclones to produce a circulating load f 300% and a corrected cutsize of 74 μ m. Assuming 50% by weight solids in the cyclone eed; a.

Explain the role of ball mill in mineral industry and why it is extensively used. ... The bed porosity is typically in the range of 35% to 40%. In practice, the mill shaft power for wet overflow mills calculated using the above expression appeared to overestimate the actual power when: ... 250 Tph; F80 = 10mm; P80 = ; Calculate the mill ...
where v = peripheral speed of the mill in feet per minute. If the observed capacity of a mill at speed n1 is = T1 tph, the capacity T2 of the same mill at speed n2 should be . The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. P = f4(F) = f1(D²)·f5(υ) Indicating that υ = πDn, and
