raw mill

Raw mill known as the raw mill, cement production process is important grinding equipment. After crushing the raw material into the tube mill, ball movement and squeeze through, being ground into a fine powder. zenith production of the raw mill less investment, less than the same size of the traditional process equipment from 35 to 50 percent, can meet 250 ~ 2500 t / d cement production line of raw material supply.

Raw Mill Equipment Works

This machine is a horizontal cylinder rotating mechanism, 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.

Raw Mill Advantages

  • 1. The investment in equipment is lower than the same size of the traditional technique and equipment: raw mill is a very mature mill is widely used in the cement industry. Raw mill lower prices, lower than the same size of the traditional investment in equipment technology and equipment, less investment in the cement plant for rapid production and high return.
  • 2. mill yield: the big end caps and the feed system uses a unique streamlined design reduces air flow resistance, increasing the effective volume of the material is easy to improve the mill output, with the same specifications of the international regulations mill compared to other parameters unchanged, while Taiwan, high yield, 4.6m × 10.5 + 3.5 type of raw material output of up to 210t / h, the overall performance reached the international advanced level.
  • 3. High grinding efficiency: a tube mill for single-chamber structure, mill lined plate combination designed for different stages with different inner tube mill liner structure, high grinding efficiency.
  • 4. The grinding and drying operations simultaneously: tube mill capable both wet production production can also be grinding and drying simultaneously.
