There are disk mill roller mill, ring mill, roller mill, Raymond mill, vertical roller mill, pendulum, it works: the material in between the rolling surfaces of two rolling or rolling with the grinding bodies (balls, rollers under pressure between) and a track (plane, sphere, disk) and crushed; the basic structure: mainly by rail grinding, grinding, power generation and transmission mechanism, air flow and facilitate the replacement device easy to change parts of the composition.
Features of vertical roller mill: 1. Processing capacity, product size for easy adjustment; 2. Vertical roller mill is easy and dry fine classifier consisting of overall equipment. Uses: chemicals, non-metallic processing, refractories and other processing industries Mohs hardness of 6 or less dry fine grinding of mineral raw materials; 3. wear roller surface using casement type structure, with different patterns and forms of the roll surface for different materials, disassembly and easy maintenance; 4. wear roller surface with high hardness and wear resistance of the alloy, the general life of consumable materials processing up to 20000h.
Five main advantages of Vertical roller mill:
1. save energy: ultra-high pressure vertical roller mill crushing process to replace the traditional crushing - grinding technology, integrated power consumption reduced by more than 60%, steel consumption decreased by more than 40%; 2. expand production: crushing ratio, vertical roller mill can be 40 ~ 120mm material crushed to -3mm below, stand-alone processing capacity to meet the 20 t / h to 1000t / h production; 3. saving investment: high grinding roll surface hardness, wear resistance, the use of carbide steel, life of up to 20000h, equipment, small footprint, construction investment; 4. environmental protection is simple: vertical roller mill is running low noise, less dust pollution, roller smooth operation, the operating rate of 95%, online maintenance, easy to operate; 5. widely used: the process system configuration flexibility, strong adaptability of materials and processing, mineral processing in favor of large-scale, automation and energy efficient development.
