Introduction :

  • Cement vertical raw mill is also called raw meal vertical roller mill, and it is the core equipment applied for cement raw meal grinding.
  • Raw mill is mainly used for grinding raw materials in cement plant and is also suitable for grinding mineral ore and other materials in metallurgy, chemical, power plant. It can work in open circuit or closed circuit with separator. Raw mill has features of various materials application, continuous running, big grinding rate, easy control of product fineness.

 
Raw mill produced by ZK Corp has two types :

  • Ball Mill for Raw Meal Grinding :Raw meal ball mill has features of various materials application, continuous running, big grinding rate, easy control of product fineness.
  • Vertical Mill for Raw Meal Grinding : In the process of Dry Type Cement Production Line, Vertical Mill is mainly used for raw meal preparation. Compared with Ball Mill, it has the advantages like energy saving.


Our Advantage

  • High grinding efficiency and low power consumption. This kind of machine consumes 20-30% lower power. And with the growing of moisture content, its energy-saving effect will be more obvious.
  • Strong dry ability. Air is used to send materials, and the temperature of the air can be controlled according to the moisture content of materials.
  • Large feeding size. The feeding size can be as large as 5% of the diameter of the grinding diameter, that is, 40 to 100mm. Therefore, secondary grinding is unnecessary for large-scale and medium vertical mill.
  • Stable chemical composition and even particle size products.
  • Simple process flow and small in size. There is a segregator in the cement vertical raw mill, which makes powder separator and elevator unnecessary. Grinded dusty air can directly enter into the environmental protection equipment.
  • Low noises, few dust, and environment friendly. There is no direct contact between the grinding rollers and grinding disc, so there is no impact sound caused by the colliding between the steel balls or between the steel ball and lining plate.


Structure :

  • Composite separator improves the efficiency of the powder.
  • With the function of automatic lifting and falling , can realize no-load starting.
  • Welded type arc plate is used for sealing, it features simple structure, reliable performance, well-sealed structure.
  • By means of the roller swing-out device, the grinding rollers can be turned out of the mill, which is in favor of maintenance.
  • The limit mechanism avoids the fiction and crash of metals between grinding roller and grinding plate, increasing the rotating stability and security.
  • Operating pressure of hydraulic system is low, can reduce the leakage failure and the mill vibration , is good for operation and management.
  • The centralized circulating oil lubrication is applied to the grinding roller bearings, which ensures the bearing operate at constant temperature and with pure oil, so that longer service life is achieved.
