Screening Partition Panels

1: Increase in Production by 40% 2: Save Electricity by 30% 3: Improve Quality of Products 4: Reduce Production Cost

Characteristics:

Screening partition panels used in open-circuit mills screen out grains of more than 2mm, which are sent back to the first chamber for future grinding. Damming rings are installed in the fine grinding chamber to control flow velocity of materials, stir grinding media in the retention area, increase cutting and rubbing.

At the same time, Φ8×10~Φ16×18 micro-segment grinding fine fully is used. Then the production can be increased by 20%. Screening partition panels can also be used in closed-circuit mills whose specific surface areas are required to exceed 380 m2/kg and mills for grinding ultra-fine fly ash and slag. The chamber length, liner structure, outlet grate plates, gradation of grinding media must be considered when screening partition panels are applied.

Service:

According to the mill grinding system parameters provided by customers, we offer structure design for screening partition panels, process parameters optimization and commissioning for production increase.
