Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size reduction could

For the PT Semen Baturaja cement plant, the customer Tianjin Cement Industry Design & Research Institute Co Ltd has placed an order for two type LM 53.3+3 CS LOESCHE mills for clinker grinding. Each of the tried and tested mills for grinding clinker are designed with a capacity of 175 t/h and material is ground to a fineness of 3,400Blaine.

Raw meal powder enters into the furnace system, it transitions into the melt phase, and clinker is obtained once furnace and cooling reactions are completed. The first melt phase is formed at 1260°C-1310°C. Clinker melt's rate increases as the temperature rises and it reaches up to 20-30% in weight at 1450°C depending on the chemical compound.

The plant is currently sourcing clinker from other producers, said Dongning Wang, Managing Director of Livetouch. PPC also recently opened a new grinding plant in Harare, its third location in the Zimbabwe. The 0.7 million tpy, US$82 million plant will grind clinker transported by rail from PPC's Bulawayo cement plant.

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption …

Grinding experiments were performed in a laboratory sized ball mill. The parameters and operating conditions used are listed in Table 2.For each test, a charge of 460 g of one of the six size fractions of clinker was fed into the mill, and the sample was ground for various periods of time: 0.5, 1, 2, 4, 6, 8, 10, 20 and 30 min (a different 460 g …
