Mar 09, 2014 Clinker Burning For the production of cement clinker, the raw meal which is known as kiln feed at this stage has to be heated to a temperature of about 1550 oC in the long cylindrical rotating kiln. The kiln feed enters the system at the top of the pre-heater and fall until the lower end of the kiln. The heat exchange occurs during this process

The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs. The rotary kiln is approximately 20 to 25 feet (ft) in diameter and from 150 ft to well over 300 ft long; the kiln is set at a slight incline and rotates one to three times per minute.

How Cement Is Made

Clinker comes out of the kiln as grey balls, about the size of marbles. Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency.

Examining the use of Fluorspar in the Cement industry

Its inclusion in the process does not behave the same way in all cement kiln systems, so lab and industrial tests are always needed prior to industrial use. Due to the nature of cement process almost any quality of fluorspar or its sub-products(i.e. HF industry residues) can be used for cement production (as low as 40% of CaF2 content) 20

CLINKER GRINDING IN CEMENT PRODUCTION

Feb 21, 2019 Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.

Cement clinker Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
