Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
The installation of liners. Length Diameter Ratio. The length-diameter ratio of the cement ball mill is relatively large. For mills of open-circuit grinding system, the length-diameter ratio is usually between 3.5 and 6 to ensure that the product fineness is qualified through single grinding; For ball mills in closed-circuit grind system, in order to increase the …

Lateral gear drives for ball mills are widespread in cement and minerals plants all over the world. They are known for their compact design and the ingenious mechanical torque split reduces the […]
An operator in a control room located between the scales selects the specified type of cement. The truck or rail car is then loaded and weighed on automated scales. It takes 6 to 8 minutes to load a truck holding 25 to 28 tons, and about 30 minutes to load a rail car holding 100 tons.
Gearless ball mill drive. The gearless ball mill drive has been established in mill construction since 1969. Large ball mills are directly driven by low frequency electric motors without a speed reducing gear between the …
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
The global trend towards single-mill cement plants is unquestionable. With civil construction cost savings, higher throughput and lowered maintenance costs, the use of single large VRMs for cement and raw grinding is the optimal choice. The sheer size requires powerful, large-scale drive gear systems. As operators look to increase …
