What is a Cement Mill? (with pictures)
A cement mill is used to make clinkers, which are key in many types of concrete. The chief constituent of Portland cement is a sintering product of limestone and aluminosilicate known as clinker. This hard, pebble like material is the ingredient in cement which causes it to "cure" and harden to form the mortar or concrete used so extensively in construction.

Cement mill - Wikipedia
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Combining forces - International Cement Review
High-pressure grinding rolls (HPGR) have been used in cement production for more than 30 years. Since the first industrial application for comminution in 1985, these highly-efficient machines have gained in importance with their main applications in the grinding of brittle materials. 1 HPGRs were often added upstream to existing cement plants with a ball mill and an air …
Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Cement Mill Separator - Cement Plant for Sale | Cement ...
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.

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.
