1. Set Pregrinding Process. Pregrinding by roller press, etc., under the high pressure generated by the machine roller, the particles between the materials press each other, resulting in lattice splitting and crushing displacement, which can greatly improve the effective power utilization of grinding compared with the singleuse mill. 2.

In mineral beneficiation, grinding is also the most energy~onsuming process. Energy consumed in ore grinding in various mills as compiled by Hartley et al. [2] is shown in Table 1. It is to be noted that the energy consumed in grinding alone represents up to 70% of the energy for the whole beneficiation process (see Table 2 reproduced from a 1934

Modern dryprocess cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kgcl of thermal energy and 100 kWh/mt of electrical energy. Older plants with inefficient systems, combined with operational and maintenance failure, tend to have much higher energy consumption.
