Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass.
Possible drives include gear rim/pinion, lateral, or central drives. If the processing material is wet, cement mills can also be equipped with a drying chamber. The drying chamber can be integrated into the mill or flange-mounted to it. It is equally simple to design the mill shell in one piece or in several parts (for transport reasons).
Cement Milling Cement Milling Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy.
Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions

Cement grinding is a continuous process: the clinker/gypsum/additions blend is continuously fed at mill entry and extracted as fine fraction from separator. The mass of material sent back to the mill as coarse fraction can be several times the fresh feed, depending on the fineness required and separator type.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.

horizontal separation of 10 feet between parallel pipes, and 18 inches of vertical separation. Many states have adopted these standards as guidance or regulation. In 1968, engineers at Utah State University investigated the effects of trench excavation on separation distances from a buried parallel pipe. Their work resulted in a relationship
The vertical position of its centrally-positioned feeding chute prevents the damp material from sticking. The material to be ground thus goes directly to the grinding table of the vertical mill. The DSK is often used for the separation of coal or petcoke, and provides a top cut of up to 20 µm.
