A significant portion of the cost to produce a ton of cement resides in the grinding costs. The industry standard for decades has been horizontal ball mills which rely upon heavy balls cascading inside a fast turning mill to crush the clinker into the fine cement powder.
However, despite a generally good performance of vertical roller mills used for grinding of cement and related products the vertical roller mill is still inferior to the ball mill in terms of sensitivity to variations of mill feed quality (fineness) and mill feed rate. Product quality.In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 g is necessary to compensate for the strength reduction resulting from the addition of 1 limestone. 3. The mill type and process system play an important role.
Vertical cement mill has high grinding efficiency and low power consumption (20 – 30 less than ball mill). The granularity of the feeding material is larger(VRM cement mill is 80mm-120mm, cement ball mill is less than or equal to 30mm). Cement vertical mill occupies less space and saves 30 of construction cost.Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60 dehydration of gypsum to optimize cement strength without excessive false set.
