The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
to cement, limestone particles modify the grain size distribution. The final effect depends on the fineness and the amount of powder. In the favourable case where an improvement in blended particles size distribution is observed, i.e. a continuous sieving curve, limestone particles fill the
The extent of reaction of limestone with cement clinkers is relatively low than the corresponding values of cement clinkers, the probable cause for this as stated above arise from the low solubility and low reactivity of limestone particles, though other factors of limestone, including fineness, particle size distribution, etc., do have influence on its reaction degree in blended system.
portland cement and portland-limestone cement with an identical particle size distribution (PSD), it has to be considered that the laser method is based on the assumption that all particles have a spherical shape, which neither ground limestone nor clinker really have. As limestone is much easier to grind than clinker, the fine limestone ...

Determination of Bond Work Index of Lucky Cement Limestone Pakistan Niaz Muhammad Shahani, Zhijun Wan, Abdullah Rasheed Qureshi, Muhammad Ali, Naseem Ali Abstract—The Bond work index is a research methodology, which is widely used for the estimation of power required to grind the materials.
However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system. Capacity of cement mills

Mar 26, 2015· Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements ...
Jet mill grinding of portland cement, limestone, and fly (a) Particle size distribution and (b) corresponding mean particle diameter of OPC2 (g) 100 60 60 60 cement/limestone blends with particle size corresponding to 10% and 90% Fly ash (g) 0 40 40 40 cumulative volume after zero to three passes through jet mill grinding.
But limestone particle size is smaller, the higher the energy consumption broken. To grind finer limestone powder, the need for a larger mill, high energy consumption, increase investment, which requires trade-offs, considering. Usually it requires limestone powder through 250 mesh or 325 mesh sieve rate of 90%.
