The experiments successfully validate the FEM simulations and directly demonstrate flow and segregation phenomena. The results vividly illustrate distinct zones of fine and coarse …
ادامه مطلبLarge clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.
ادامه مطلبClinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of bucket elevator for classification of the ground cement into two a streams – coarse and fines.
ادامه مطلبVertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.
ادامه مطلبSome 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 in some cases the formula will result in the prediction that 100mm balls be used to deal with large clinker particles.
ادامه مطلبExtraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.
