Addressing the Unwanted Impacts of Grinding Aids

Powerful grinding aids avoid this stickiness. They broaden the interfacial gap between the limestone particles and thereby boost the powder flow of PLC. 5 However, a potential disadvantage of good powder flow is the backflow of cement on an inclined conveyor belt (see Figure 2).

Performance Enhancer for Portland Limestone Cement (PLC)

Tailor-made SikaGrind for PLC are very efficient grinding aids. The tendency of limestone to agglomerate is extremely well reduced by SikaGrind, therefor the share of limestone in the segment of very fine particles is reduced but the fineness of the clinker increased. In this way SikaGrind helps to reduce porosity and chloride diffusion which ...

Progress with Grinding Aids for Vertical Roller Mills

The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids.ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s ...
