The ball mill has one component, m diameter, and m length with 240 t/h capacity (made by PSP Company from Prerˇ ov, Czechia).
WhatsApp: +86 18838072829The cement industry makes use of four mill types: the ball mill, the vertical mill, the roller press (also known as highpressure grinding roll) and the horizontal mill. A report on the development over time towards those mill types, which was largely determined by efforts to achieve higher energy efficiency, was already presented in [1].
WhatsApp: +86 18838072829The cement industry is highly energyintensive, consuming approximately 7% of global industrial energy consumption each year. Improving production technology is a good strategy to reduce the energy needs of a cement plant. The market offers a wide variety of alternative solutions; besides, the literature already provides reviews of opportunities to improve energy efficiency in a cement plant.

WhatsApp: +86 18838072829The mills are of the rotary ball type (previously described). The process consists of grinding the clinker with about 5 percent gypsum to regulate the setting time of the cement. The finishing mills are sometimes sprayed with water to keep them sufficiently cool and to minimize dehydration of the gypsum, which could lead to "false set" problems.
