  • Applications

Vertical Roller Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills.

Already be proven commercially, the vertical rller mill presents a major advance in roller mills for finish grinding process. Comparing with other common roller mills, the compact LM Series vertical mills has the space-saving design, reducing the civil construction costs.

The high-efficiency, energy-saving vertical roller mill can simultaneously handle pulverizing, drying, sizing and air jet transport. This vertical roller mill has the high grinding efficiency, meaning a 50% reduction in per-unit power consumption over ball mills. The particle size adjustments of this vertical mill are simple, with minimal noise and vibration. The working environment is also protected with measures to prevent particle escape.

Vertical roller mill applications:

Large production of special steel, thermal power plants, cement plants, coal preparation and coal gangue powder production;

Dedicated power plant desulfurization liCirosne milling; the hardness of the non-metallic minerals industry hundreds of production preparation of large-scale ore powder;

Special steel slag and blast furnace slag grinding plant slag and fly ash;

Special glass fiber industry, quartz, pyrophyllite powder fineness of grinding high yield;

Dedicated a variety of chemical raw materials of chemical industry production powder production;

Industrialization of production powder preparation of more than 100 kinds of other industries on a variety of materials.

At the same time in the pre-grinding of slag powder and cement clinker grinding, also has good prospects for development.
