17 4.Grinding system Ball mill is the earliest grinding equipment used in cement production industry, and it still plays a leading role. Although its efficiency is very low, for example, the power consumption of single particle is only 6% - 9%, the maintenance of ball mill is simple and reliable, especially for cement clinker grinding.
1.. IntroductionConventionally multi-compartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls (HPGR), vertical mills and Horomill ® in cement plants. As recorded …
1. Roller Press Cement Pre Grinding System. The most noticeable feature of the roller press cement pre grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.
The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production. Also the feed materials which are coming from roller press to the ball mill are powdery form instead of Clinker material.
Nowadays, in the field of cement grinding system of the world cement industry, the major cement grinding equipments include loop flow ball mill, roller press, ball mill semi-finishing system, and vertical mill system, in which ball mill and vertical mill are 2 major cement grinding systems in Cement Manufacturing Plants.
When grinding cement, the abrasion of the ball mill is 300-1000 g/t, while that of the roller press is 0.5g/t, so it can meet the requirements of grinding white …
