The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: 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.
Cement industry is one of the major markets for industrial fans. Fans in cement industry are heavy duty and perform two basic functions i.e., supply of air or removal of exhaust gases and material ...

The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed …

The clinker cooler exhaust fan plays a critical role in the cement making process. Raw mix enters the kiln and is heated to 1,450 degrees Celsius where it is transformed to clinker. Upon exiting the kiln, the clinker is cooled to 100 degrees Celsius by the clinker cooler fans which blow cooling air through the clinker.

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime ...

The clinker grinding time is on the high side for a long time, which leads to the difficulty of normal grinding operation of the cement mill, and the output of the cement mill is greatly affected. Meanwhile, the company's clinker customers have complained for many times that the clinker is difficult to grind and the cement cost increases ...
Clinker litre weight (grams/litre): A convenient supplement for free lime measurement is the more rapid determination of litre weight of clinker sample from the cooler discharge to approximately +6/-12 mm and weighing a standard 1 litre volume. Normal range of litre-weight is 1100-1300 g/L. Low litre weight means high free lime and dusty ...
Clinker cooler fan Since it is not located downstream from the fabric filter, the clinker cooler fan is of a similar design to the raw mill fan but is much smaller (designed for a 0.72MW motor with a power consumption at nominal conditions of 0.3MW). Due to the abrasive dust, a double layer of wear protection was added, including 3mm
In actual calcination, a complete clinker calcination system includes the cooler, pulverized coal combustion equipment, blower, exhaust fan and the dust collector. However, in the latest calcination system, the addition of preheater and precalciner reduces the energy consumption and optimize the performance of cement kiln to a large extent.
Precalciner, also known as cement calciner, is a kind of high-efficiency direct combustion solid-gas heat exchange cement equipment. It disperses and suspends cement raw meal powder in airflow, making fuel combustion and calcium carbonate decomposition happen in a short time (generally 1.5 ~ 3 seconds). To some extent, it replaces part of the ...
Clinker process in the cement manufacturing involves cooling of the clinker i.e., the high temperatures present in the clinkers are lowered by driving continuous air. Cooling fans are used to blow cool air and bring down the temperature of the clinkers from 1500 °C to 100 °C. Use of cooling fans maintains the quality of the clinker.

Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles.

Downstream of the fan, the gas volume flow is divided: part of it flows back to the mill, the remainder is evacuated through an exhaust gas chimney. The mill is equipped with an external material recirculation allowing the reduction of pressure loss in the mill. It can also be used for emptying the mill in case of maintenance.
