Ball Mill
RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time
The ball mill cyclone overflow can be split to divert up to 120tph at 30% solids through the pilot Flotation circuit. Design flotation time is 14 minutes and concentrate production is 40-50 dtph. Feed can also be obtained from the Pre oxidation storage tanks.

What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

Ball Mill Parameter Selection & Calculation
1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

Design aspects of large ball mills.
Large ball mills often incorporate trommels for screening of the mill discharge. As grinding mills have increased in size, the trommels have grown correspondingly from relatively minor structures to very large rotating components which can be larger than many entire grinding mills manufactured 10-15 years ago.
