Slag grinding with the Polysius Roller Mill in China

The grinding plant for Anshan was designed for a grinding capacity of 90tph at a ground blast furnace slag product fineness of 4000cm 2 /g according to Blaine. However, following the market trend, the plant now produces 83tph of ground blast furnace slag with a fineness of 4300cm 2 /g (acc. to Blaine).

A study of intergrinding and separate grinding of blast

1/3/2000 · 1. Introduction. Since the first discovery of cementitious properties of blast furnace slag (BFS) by Emil Langen in 1862 and particularly after the oil crisis in 1970s, manufacture of blast furnace slag cement (BFC) has substantially increased due to greater emphasis on energy conservation, utilization of waste materials and certain technical advantages over ordinary Portland cement (OPC

Comparison of intergrinding and separate grinding for the

For cements containing blast furnace slag, unlike the natural pozzolan-incorporated cements, intergrinding consumes more energy than separate grinding to reach 3500 cm 2 /g Blaine fineness. However, the lower energy-consuming separately ground P + S cement still shows lower strength values than higher energy-consuming interground PS cement.
