Cement Mill Feeding. Cement mill feeding section facilitates a reliable feeding of clinker, gypsum and other additive like limestone, slag, fly ash etc. Mill feeding consists of material hoppers, weighing, conveying to mill. Mill Feeding Hoppers. Hoppers for clinker/Gypsum/ Additives serve the purpose of providing a buffer storage for mill feed and a convenient
The cement mill 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.
Raw Mill Feeding. In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Pre-homogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.

The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
