Seebach and co-workers [5] reported plant results from of a combined grinding process. The process had a closed-circuit HPRM system producing an intermediate product upstream of a conventional closed-circuit ball mill system that produced a final cement product of 3200 cm 2 /g Blaine fineness at a throughput of 192.7 …

Industrial closed-circuit tube (or ball) mill schematically presented in Fig. 1 was used for cement production. The clinker initially passes through a double-deck screen, where all particles larger than 10 mm are sent to a pre-crusher.A measured fresh feed mixture (B0) of pre-crushed clinker, gypsum, and pozzolan is introduced in the mill.

As the clinker particles are ground further, smaller media are more efficient at reducing the particle size even further. Grinding can be either 'open circuit' or 'closed circuit'. In an open-circuit system, the feed of incoming clinker is adjusted in such a way that it achieves the desired fineness of the product.

A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media. As the clinker particles are ground further, smaller media are more efficient at reducing the particle size even further. Grinding can be either 'open circuit' or 'closed circuit'.
