Introduction of GGBS vertical roller mill

  GGBS vertical roller mill is the equipment to grind Ground Granulated Blast furnace Slag (GGBS) into small particles.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.

Iron extraction system

It is a well-known fact that iron particles in the granulated blast furnace slag are the main cause of wear in the mill. Therefore it is extremely important to remove the maximum possible amount of this iron.

The external material circuit is very well suited for this purpose, because it handles a large quantity of material, some of which is already partly ground.

Wear protection

The grinding plant, which is carefully maintained by the owner, provided high availability and trouble-free operation. 

None of the wear protection plates in the mill housing and in the grit cone of the separator have yet needed replacing.

Only the ceramic castable in the upper housing section of the separator was replaced by wear-resistant steel plates soon after the commissioning.
