First, vibrating feeder feeds limestone materials into grinding chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone, which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.
“We bought the first crusher, a C125™ jaw crusher from Metso, in 1997; the best part is the crusher is still operating in one of our quarries 20 years later. Seeing the crusher operating even after 20 years gives us confidence in the Metso brand and its equipment,” divulged Mr. Manjeet Chawla. He added, “The Indian market is one of the biggest markets for aggregates and we are one of the biggest mine operators in north India. Initially, we operated more than 300 local crushers in our quarries, as there were frequent breakdowns and the demand was not fulfilled. Buying that first crusher from Metso changed the perception, as production quality was good, crusher uptime was high, and we were able to meet the growing market demand for aggregates.”

The stable bed is the basis for the grinding of the Hammer Mill bed, the key to normal operation. When the bed is unstable, the wet slag that is ground into the mill is extruded in a large amount and cannot be ground. The thickness of the layer can be adjusted by adjusting the height of the retaining ring. The appropriate height and their correspondence to the production of Hammer Mills should be first identified during the commissioning phase. Under normal operation, the thickness of the Hammer Mill after compaction by the grinding roller should not be less than 25~40mm. And the grinding and feeding should adopt the operation mode with less wind and small rolling pressure to flatten the material bed to make the Hammer Mill run stably.
