The efficient operation of a cement mill is vital for the overall productivity and quality of the cement production process. Constant adaptation and optimization are essential in the dynamic environment of cement manufacturing to meet quality standards and operational goals. The ball mills achieving the right balance in material feed is crucial.
The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.
In general the grinding efficiency of vertical roller mill is 80% as much power as cement ball mill, reduce about 30% power consumption. Advantages. The finished product quality control is quick, the adjustment product is flexible,easy to realize the intelligent and automatic operation. Disadvantages.
Grindability of a 95/5 OPC at various Blaine fineness: o 27-32 kWh/t at 3,000 cm²/g. o 39-47 kWh/t at 4,000 cm²/g. o 58-69 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not required ...

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...
In filling mill by grinding balls on 40 – 50% and non-smooth liner, the outer layers slip is virtually absent, but the sliding of the inner layers one on another observed in various modes of operation mill. In a monolayer filling mill by grinding media, they rotate around their axis parallel to the drum axis of rotation.
Optimized mill operation will be supported by a digitalization package incl. intelligent mill controller. The mill is operating very successful since mid of 2021. Kenya, India & Indonesia
