Crushed limestone and gypsum are popular cement additives. However, the crushed limestone and gypsum must be pulverized into 200mesh powder before being used to produce cement additives. Joyal offers MTM Trapezium grinding mill and MTW European trapezium grinding machine for limestone grinding and gypsum grinding. Aside from single mill units, Joyal also offers customized solutions, for instance, you can choose trusted spare parts for the whole grinding plant, such as ABB or SIMENS.
Cement additive, mainly composed of limestone and gypsum, offers all the benefits of traditional grinding aids such as increased grinding efficiency and cement flow ability. In addition, in many cases it has been found to improve the strength, particularly the late strength of cement. It allows the cement producer to trade off strength gains for reduced fineness and achieves lower unit power savings compared with other grinding aids. It has also been known to improve the workability of cement mortars and concrete. Joyal has been engaged for decades in mineral material grinding equipment R&D and manufacturing. Our MTM Mill and MTW Mill which adopts advanced European technical innovations can meet your limestone and gypsum processing requirement for cement additive production.
Limestone or gypsum raw materials are firstly crushed by jaw crusher to specified size, and then elevated into a hopper. Then vibrating feeder sends evenly and continuously the materials into the grinding chamber for powder processing. The ground limestone or gypsum grains are carried by air from the blower into the classifier for classification. The finer powers are blown into cyclone collector, and the rough grains will be recycled back into the grinding chamber for further grinding, forming a closed circuit. Final products of 200mesh and less in size are poured out through out-put valve.
