From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill. The milling process generates heat and excessive mill temperatures are undesirable.
Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker.

The grate cooler is a quenching type cement cooler apply for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types ...
Cooling air requirement is generally designed at 2.2-2.5 nm3/kg-clinker. Either hammer crusher or roller crusher is used to break lumps of clinker before coming out from cooler. Water spray or Air to Air heat exchanger is used to cool down cooler vent air before de-dusting in ESP or bag filter.
During cement grinding, the material temperature may be higher than 100 ℃, leading to dehydration of most gypsum or complete dehydration, causing coagulate of cement, which requires corresponding cooling measures, including mill ventilation, cylinder water cooling, etc. 4.
As an essential part of the cement kiln system, a rotary cooler is used to cool the clinker discharged from the cement rotary kiln. The rotary cooler also helps air to absorb the large amounts of heat carried by clinker, heating the combustion air up to the high temperature, strengthen the calcination, and reduce the energy consumption.

The primary cooling technologies used are reciprocating grate coolers and planetary coolers. The designs of these clinker coolers have significantly changed in recent years. ... the discharged cooled clinker and other additives are mixed in the stockpile and then conveyed to the cement ball mill using a Deep Bucket Conveyor for final grinding ...
Fig. 3. cement mill section in dry process It is important to note that the strength properties of cement are considerably influenced by the cooling rate of the clinker. The rate of cooling influences the degree of crystallization, the size of the crystal and the number of amorphous materials present in the clinker.
Cement mill, raw mill, rotary kiln, coal mill, lime kiln, cooling machine, etc. are all included in Cement Making Machines.

Phase IV: Calcination. The calcination is the core phase of the cement making dry process. The calcination of the preheated raw meal takes place in the rotary kiln of the cement plant. The rotary kiln is a huge rotating furnace in which the raw meal is heated up to 1450 ⁰C and turned to clinker.
A cement mill (or finish mill in North American usage [1]) 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.
Thus these fans help ineffective burning of coal inside the mill. Cooling Fans: Cement manufacturers use a large number of cooling fans to blow cold air to the cooler and to cool the clinker from 1500oC to 100oC. Usually, 5 to 15 cooling fans …

Cement is produced by heating calcium (usually limestone) silica, alumina (typically clay or shale) and iron (steel mill scale or iron ore) in cement kilns. The cement burning process (preheater) is rapidly changed and accordingly the heat consumption rate is remarkably improved.
