In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles.

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

A conveyor belt (or belt conveyor) consists of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them.

The offering of mobile crushing station eliminates tedious pieces of steel structure, the construction of the foundation and save a lot of time.

As a professional stone production line manufacturer, our stone production line equipment includes Crusher (sand making machine), jaw crusher, impact crusher, vibrating screen, belt conveyor, hammer crusher, etc.

Mineral magnetic is the basis of mineral magnetic separation, Because of the nature of the atomic structure of the different material, it has different magnetic atoms.

The electromagnetic coil can generate magnetic ranging from the strength. By this principle, magnetic separator in ore beneficiation selects the ore containing magnetic.

The transmission parts of ball mill mainly consist of gear box, small and big transmission gear, electric motor and electric control panel.

Easily-damaged parts of impact crusher mainly include: plate hammer, liner and bearing.

China mining machinery industry grew a lot in 2011. But compared with the successive decades of rapid growth, the main economic indicators were in the overall fall. The profit growth was lower than the sales growth in 2011.
