2. The technical process is simple and saves infrastructure investment. Vertical mill has a separating machine, and uses hot smoke to convey the materials, so that no powder separating machine and elevating machine are needed. The gas containing dust will directly go into the powder collector for collection, so that the grinding system is simple, the failure rate is low, running rate is high.
3. Strong drying capacity. Vertical mill adopts hot air to convey materials, and when grinding materials with high water content, the inlet air temperature can be controlled to make sure that the products will reach the final water content. Vertical mill can dry the materials with the water content 12-15%. 4. Small abrasion of the metal. In the running process of vertical mill, no metal materials directly contact with each other, so that the abrasion is small, and the unit abrasion consumption for limestone is generally 4-6 g/t.
