Cement manufacturers buy clinker for their cement plants in areas where raw materials for cement are scarce or unavailable.

What does clinker mean in cement?

Definition of cement clinker : the glassy clinkerlike product of fusing together clay and limestone as the first stage in the manufacture of portland cement.

How is clinker formed?

Clinkers, also known as slag, and in coal fired boilers consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Clinkers resemble volcanic ash and lava. They occur in the high-temperature furnace area of the boiler.

What is clinker in chemistry?

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. ... It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

What does clinker look like?

Clinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit. Clinker often has a glassy look to it, usually because of the formation of molten silica compounds during processing.

What is the difference between clinker and cement?

The main differences between clinker and cement are given below. Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. ... The primary use of clinker is to manufacture cement.

How do you stop a clinker?

The best solution is to avoid the deposition of clinker is precaution. Blaming poor quality coal may prove harmful for the boiler. Instead of very poor quality coal having high ash and mineral content, clinker formation may be avoided by a sincere attitude of power plant engineers.

IN ADDITION, BREATHING CEMENT CLINKER DUST OVER A PERIOD OF TIME MAY IN SOME CASES RESULT IN CANCER AND OTHER DISEASES.

What is clinker role in cement production?

• 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 to make clinker cement?

• grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill );
• heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;
• grinding the resulting clinker to make cement (see Cement mill ).

What is the meaning of Dutch clinker?

• Clinker is sometimes spelled "klinker" which is the contemporary Dutch word for the brick. Both terms are onomatopoeic, derived from the Middle Dutch klinkaerd, later klinker, from klinken ("to ring, resound"). Clinker bricks are also known as Dutch paving bricks.
