4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system.Web

The #1 issue for coal mill operators is stickiness or coal build-up on all the material handling equipment surfaces, including the mill feeder. Coal remains a common fuel choice for firing cement kilns in North America. Most plants receive their raw coal in a form that requires on-site grinding, using VRM's along with other mill types.Web

Water injection helps to control the temperature in the mill. There are different causes of heat generation in the grinding process, so different water injection systems are required. For example, if the fresh material is very hot, water injection, e.g. clinker >120°C, a water injection system is used at the mill inlet.Web
