A study on the effect of ball diameter on breakage,

The results show that the study on the effect of ball diameter on the grinding gives more different results than other investigations. The variation in specific rate of breakage with feed size is independent of ball diameters and kind of materials. Keywords: Ball mill, Ball size effects, Clinker, Grinding, Limestone Comminution is extremely energy intensive, consuming 3-4% of the electricity,Design, Construction and Performance Analysis of a 5,,diameter of 210 mm is 373 mm, and the required shaft length and diameter are 712.2 mm and 30 mm respectively. The results of the particle size analysis, before and after the grinding test, show that the values of F50, F80, P50, and P80 of the limestone that was fed into the mill are 650 microns, 1950 microns, 47.5 microns and 85 micronsectively. Keywords: laboratory ball mill, bond’s,Limestone - Wikipedia,Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more,

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.limestone grinding mill, limestone grinding mill,fine limestone powder grinding ;limestone powder making machinery It can grind more than 100 kinds of materials, such as calcite, chalk, limestone, dolomite, kaolin, gypsum, talc and so on.
