Raw Mill

Raw mill is the key equipment for grinding and grinding of cement. It is a new efficient, energy conservation and environmental protection of the grinding equipment, has the advantages of high grinding efficiency, low power consumption, low noise, low dust pollution and so on. Our company can meet the raw material supply for the cement production line combination of 1000-10000t / D. The drying of raw material vertical mill, grinding separation process is a unit, manufacturing installation smaller footprint, reduce the civil engineering cost, vertical cement plant project cost is about 20 - 25% greater than the capacity of the ball mill system is the same.Raw Mill is mainly used in grinding of cement raw materials like limestone and others. Grinding can be used to open streams, but also to the composition and the separator flow grinding circle.

Products Features

  1. The compound separator improved powder selection efficiency.
  2. Has automatic function of roller uplifting and down falling can realize idling startup.
  3. Adopt the sealing of jointing arc board, simple and reliable in structure with good sealing effect.
  4. Resorting to the roller turning equipment can conveniently turn the roller out of the mill for the overhauling.
  5. Mechanical limiting structure can avoid the direct metal friction and collision between the roller and millstone, increasing the use security.
  6. The operation pressure is low in hydraulic pressure system, decreasing the oil leaking failure and vibration of mill, which is conductive operation and management.
  7. Roller bearing adopts the concentrated cycle lubricating of thin oil, guaranteeing the running of the bearing under the conditions of low temperature and pure grease and effectively prolonging longevity of bearing.
