Milling Equipment for the Cement Industry

Bradley’s material processing equipment is used to pre-grind raw materials such as cement clinker for use in “ordinary Portland cement” manufacturing.  But there are several varieties of specialized cement that differ from the GU – General Use Portland Cement.  These Special Cements incorporate various additives to produce characteristics such as higher strength, self-leveling qualities, and more.

Bradley milling and classification equipment is commonly used to manufacture many of the additives used in the production of specialized cements.  In particular, waste from other industrial processes such as steel mill slag and fly ash can be efficiently ground to powder for incorporation as pozzolans to increase the strength of cement.

Environmental Benefits – In countries where fly ash reserves are limited, the specifications for cement have been adjusted to include 10-15% limestone as a filler which has led to changes in BS7979 and CEM1 specifications.
