mill

After the cement mill is the material to be broken, and then to smash the key equipment. Cement ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding . Cement mill, also known as cement mill, grinding equipment is the most widely used, including lattice-type ball mill, cement mill, overflow ball mill is a mineral processing industry and other industrial sectors most commonly used grinding equipment, ball mill is mainly used grinding various hardness of coal for thermal power generator boilers and relevant industrial sectors qualified pulverized fuel preparation, tube mill grinding and grinding raw materials of various types of cement and cement clinker cement mill grinding of raw materials mainly used in cement, can also be used for grinding other materials related to the industrial sector.

Cement Mill Working Principle

Cement mill for cylindrical rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feeder evenly into the mill first warehouse into the compound by the air shaft spiral, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height after the fall, have severe impact on the material and abrasive. The material in the first position coarse, the single-compartment plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation.

Classification And Characteristics Of Cement Mill

  • 1. Ordinary cement mill: Most ordinary cement mill circuit grinding system for, which is characterized by high efficiency grinding mill yield, power consumption province, especially grinding slag cement, performance is more prominent. General mill output can be increased by 15-20%, power consumption is reduced by about 10%, in addition, the finished temperature can be reduced 20-40 ℃, the product is also easy to adjust the fineness.
  • 2. high yield fine cement mill: high yield fine cement mill is mainly used for open-circuit grinding system. It features a simple system equipment and processes, investment, plant less area; the mill structure using advanced special compartment inside the separator device, fine grinding compartment increased activation device, a dedicated end mill discharge grate board, to minimize the size of the abrasive grinding media positions, greatly improving the grinding efficiency, achieve high yield, low energy consumption purposes.

Advantages Of Cement Mill

  • 1. Spindle good performance, high capacity
  • 2. Using a large diameter main bearings double row self-aligning bearing sticks, instead of the original plain bearings, reducing friction, reduce energy consumption, the mill is easy to start.
  • 3. Retains the cap structure in the form of ordinary mill, expected out large-caliber, large capacity.
  • 4. Simple structure, stable operation
  • 5. Feeder into joint feeder and two drum-shaped feeder, simple structure, split installation.
  • 6. No inertial impact, equipment running smoothly, and reduced parking mill downtime maintenance time and improve efficiency.
