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.Acts as a grinding aid and helps stabilise the grinding bed in the mill. However, it also presents the risk of pre-hydration. This is where the use of vertical mills for slag grinding offers a further benefit as the mill not only grinds the material but also dries it in the process. The normally-moist slag, with an eight per cent water content,.
