PLC is produced by inter-grinding Portland cement clinkers with limestones, replacing a certain percentage of the energy intensive cement clinkers with raw limestone. Limestone powder in PLC contributes to improved early age strength by densifying the microstructure due to compact particle distribution and reduces embodied CO 2 of the cement .

Limestone Mill is widely used for the grinding field of limestone. After being grinded by the limestone grinding mill ( Raymond Mill), the limestone powder can be from 40 mesh to 325 mesh. The final powder size can be adjusted by the analyzer machine continuously. Limestone Grinding Mill Advantages : 1. Compact structure, less floor area needed.

Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock. rough crushing. After crushing the stone is sorted into different fractions by screening, after which it goes to be processed further. In the grinding process the limestone is ground to a fine powder.

LM series vertical mill is one advanced mill adopted top technology of domestic and abroad, and based on many years' mill experience.

blended cements. Cements incorporating limestone require higher grinding energy to obtain the same strength class [3]. Tsivilis et al. [4] investigated the grindability of limestone blended cements at different replacement ratios (10, 20, 30, 40 %) and at different grinding times (35, 50, 65, 85 minutes).

2. GENERAL DESRIPTION OF LIMESTONE GRINDING SYSTEMS (LGS) The purpose of this system is to grind lump limestone of Size 25 mm (Max) to powder and for preparation of limestone slurry. The duct from the limestone silo hopper feeds the limestone to the gravimetric feeder. The Gravimetric feeder feeds limestone to Wet ball mill system.
