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.

All You Need to Know About Mineral Processing

Pionera biopolymer depressants are added to the froth flotation process to maintain or produce hydrophilic surfaces on minerals so they will remain in the pulp rather than float with the froth. The biopolymers selectively depress gangue materials such as pyrite, clay, and talc through dispersion. Biopolymers adsorb onto gangue minerals preferentially over valuable minerals.

Principles of Froth Flotation SpringerLink

To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed.
