Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Gravity Concentration in Artisanal Gold Mining

Generally, the applicability of gravity concentration equipment for different gold ores is related to the grain size of the liberated gold particles. As shown in Figure 3,some types of equipment are much more efficient to concentrate fine gold particles than others but most of them are not very efficient for grain sizes finer than 0.074 mm (200 Tyler mesh).

Advantages Of Using Gravity Concentration For Gold

2021-8-2  Stop limiting the amount of gold you could be recovering and speed it up! Gravity concentrators produce gold from ore in a matter of minutes or hours rather than days or weeks. By introducing concentrators into your circuit, you can experience faster recovery times, allowing you to produce gold more quickly, which in turn improves your cash flow.
