What is a vertical roller mill

Vertical roller mill ( grinding ) is the dawn of Heavy Industry and Technology to address the industrial mill output is low, energy consumption and higher technical problems, absorb advanced technologies combined with our years of design and manufacture of advanced mill concept and market demand, after years of concentrated design improved Large grinding equipment . Vertical roller mill using reasonable and reliable structural design, with advanced technological process, set drying, grinding, powder selection, improve the integration, especially in the large grinding process, can meet customer demand, the major technical, economic indicators reached the international advanced Level .

Vertical roller mill applications

• Special glass fiber industry ‘s largest high yield pyrophyllite powder fineness of grinding ;
• Private coal gangue powder industry powder produced a large output ;
• Special chemical industry raw materials, high production of various chemical powder production;
• Non-metallic mineral industry, a variety of low, medium and high hardness of the hundreds of species of large-scale ore powder production preparation;
• Hundreds of species of other big industry production of a variety of materials, powder preparation;

Vertical roller mill Features:

• operating costs low:
  1. mill efficiency, vertical roller mill with roller compacted ground and feed bed materials, low energy consumption, milling system power consumption 40-50% lower than the milling system, and with the increased humidity of raw materials, section Electric effect is more significant.
  2. metal loss, liner and roller with a special material, long life, reduced operating costs, high utilization ;
  3. into the grinding material particle size of up to roller diameter of about 5%, usually 40 ~ 100 mm, it can be saved two medium-sized vertical mill grinding.
• construction costs low:
  1. The grinding process is simple, and milling system can be reduced compared to an area of about 50%, reduced by about 70% of construction costs, building size, occupy less space .
  2. set of broken grinding, drying, grinding, grading conveyor in one, the system is simple, compact . Can open layout, making low-cost construction .
• easy and reliable operation :
  1. with a control device, can realize remote control, easy to operate .
  2. The roller cover and the disc has to prevent direct contact liner quality control device, to avoid fragmentation of severe vibration .
• drying ability, vertical mill using air transportation of materials, the grinding of materials for large water inlet temperature can be controlled so that products reach the final water, drying in the grinding of water up to within 12 to 15 % of the material, even drying Dry milling, drying only water for 3 to 4 % of the material .
• stable quality, uniform particle size distribution . Material in the mill residence time is short, easy-to- size and chemical composition of the product testing and control, product quality and stability .
• easy maintenance, through the maintenance tank, turn rotating arm, roller, liner can be replaced in a very short time .
• environmental protection, energy saving ; vibration, low noise, low dust, clean operating environment to meet the requirements of environmental protection .
