GGBS Vertical Raw Mill is the equipment to grind Ground Granulated Blast furnace Slag (GGBS) into small particles. In China, quality GGBS (fineness:4200-4500cm2/g) produced by vertical roller mills are being used to substitute clinker in conventional cement manufacturing as well as to partially replace OPC for ready-mixed concrete production, for which the percentage of GGBS usage is typically at 10-15% and 20-25% respectively.

High-performance separator and optimised airflow ensure high separation efficiency and low pressure loss for energy saving.

Unusually large rollers permit coarse feed and ensure a thick grinding bed for maximum uptime.

All impact forces and dynamic reactions are small and vertical therefore easy to accommodate – prevents mill stops.

Segmented wear parts for table and rollers allow use of the most wear-resistant materials and hardfacing for long life.

Reversible roller segments ensure high material utilisation.

External circulation limits power consumption of fan.

Feed sluice ensures low false air flow and steady feed flow for minimum power consumption and optimum mill production.

The raw mill is easily adaptable to high airflow required by especially wet easy to grind materials.
