how the cooler works in cement plant

Cement Cooling System Efficient, Industrial Cement

Cement High-efficiency cement cooling. The Solex heat exchanger is capable of handling any relatively free-flowing powder or crystalline bulk solids, making it the perfect candidate to cool cement, while using up to 90% less energy compared to direct cooling methods.

Cement Kilns: Grate Coolers Cement Plants and Kilns in

The essential characteristic of a grate cooler is a layer of clinker spread on a more-or-less horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling air is

Cement production and cooling Solex

May 04, 2020· Cement is the combination of calcium carbonate, silica, alumina and ferrous oxide, which are naturally found in limestone rock, chalk, shale and/or clay. During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter.

Cement Kilns: Clinker Coolers

The cooler transfers the heat from the clinker to the combustion air, and this is also an essential function, recognised since the earliest rotary kiln designs of Ransome it is difficult to produce a sufficiently hot flame in the kiln unless the combustion air is pre-heated.

Clinker cooling International Cement Review

In a precalciner kiln, cement kiln feed passes through a temperature range from about 1000°C at the kiln inlet to about 1450°C in the burning zone then exits the kiln at around 1300°C depending on a number of factors, including the secondary air temperature and the closeness of the burning zone to the outlet.

Cement Plant Process and Instruments Used

Oct 22, 2015· The Grate cooler operates with crosscurrent principle in which the clinker is moved across the grate while cooling air blow in from below through the grate and clinker layer.The hot clinker falls from the kilin and forms clinker bed on the grate and transported through the cooler over fixed and reciprocating grates.

WASTE HEAT RECOVERY POWER PLANTS IN CEMENT

In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases. This corresponds to around 70 to 75 MW of thermal energy. This energy can be tapped by installing a Waste Heat Recovery Power Plant (WHRPP). Size of WHRPP is influenced by the moisture content present in raw material and fuel (coal).

What is Cement Clinker? Composition, Types & Uses Civil

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

How Cement Is Made

After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.
