particle size distribution curve. By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6: B It should be noted, however, that operation to achieve a wide particle size distribution (low n-value) has a cost.
The original cement plant has only one grinding mill and 2.4x 11.0m ball mill, the production capacity is seriously insufficient. ... Therefore, cement particle distribution is the key part of cement production quality control. When the cement fineness is relatively small, 80 and the sieve residue cannot reflect the grinding condition, so 32 or ...
This study investigates the evolution of dimensional properties of grinding products, namely, the mass, the surface area, the length, and the number of particle distributions with the energy input in a ball mill. The size analysis of the mill products enables the calculation of the mass distribution of each material at predetermined size classes and then the …
Nevertheless, the majority of cement clinker mills are operated using ball milling technology [2]. As the shell of a ball mill is rotated, its grinding balls move in a cataracting mode, hitting on the powder bed, and cement clinker particles are broken down to smaller sizes.
factors that affect ball mill grinder capacity and Nov 29 2021 If the temperature in the mill is too high the ball will stick which will reduce the grinding ...
Generally on cement mills, the product is ground dry in a ball mill. It has a relatively wider particle size distribution; hence, it is required to operate the ball mill in a closed circuit with a size classifier with an efficient or sharp cut of the size separator.
