The hot clinker from the kiln, fed directly on the grill at one end of the cooler, moves along the cooler length. Air current passes through the grills and the clinker bed lying on them. Hot clinkers are typically fed to the cooler at 12500C­14000C and they are cooled down to a temperature of about 1000 C.

The injection takes place at the rear part of the clinker cooler, immediately upstream of the gas outlet. Depending on the space above the clinker cooler, the nozzles can be attached both on the top and the side. We usually offer spillback nozzles for controllability. In comparrison to conventional single-fluid nozzles, spillback nozzles ensure ...

Rotary cooler and grate cooler are two hot-sale clinker coolers in the market. They all have the function of cooling high-temperature clinker but differ greatly in structure, investment, cooling efficiency, etc. Rotary cooler. The rotary cooler is …

Combustion air is the total air required for stoichiometric combustion of the fuels in the kiln and the precalciner; i.e. = primary + secondary + tertiary air Waste air of (grate) clinker coolers is the cooling air that is in excess of the combustion air and is blown to ambient (via dedusting system).

The clinker cooler, also known as grate cooler or cement cooler, it is a necessary equipment of cement clinker production. The clinker cooler is mainly used to cool and transport the cement clinker. At the same time, cement cooler also provide hot-air for rotary kiln and calciner, it is the main equipment of heat recovery for burning system.

Cooler Controller (PFCC) can be integrated with the hydraulic PLC. The PFCC is pre-programmed with advanced algorithms that generate optimized set points for cooler lane movement and flow set points for aeration fans, based on clinker level measurement and other process parameters measured in the cooler as well as at other point in pyro section.

Injecting water into the clinker cooler provides a remedy here. The cooling of the gas also causes the gas volume to reduce and protects downstream plant components from excessive gas temperatures. This reduces operating costs and avoids additional investment costs for a …

In the production of cement clinker, the clinker used in a clinker cooler process heat, for example, used to generate electricity. For this purpose, 20 hot clinker is placed on a grate 11 of an oven and cooled there with a cooling gas, while the clinker bed 19 is transported from a furnace-side clinker inlet 17 to a clinker outlet 18. The cooling gas is withdrawn via a clinker …

The clinker cooler uses air to rapidly cool the hot clinker leaving the kiln, thereby stabilizing the C3S clinker phase and obtaining a high efficiency level. In modern clinker coolers, the cooling air passes through the clinker at right angles, whereby the air absorbs the thermal energy.

Reduce your clinker cooling costs with the Cross-Bar® Cooler. Our Cross-Bar Cooler is the latest evolution in clinker cooling technology. Based on proven FL systems, it incorporates advanced clinker cooling innovations to give you low installation, maintenance and operating costs – and a very attractive total cost of ownership.

The clinker cooler. There are various types of cooler - we will consider only one, the 'grate cooler'. Grate cooler: the hot clinker falls out of the kiln and moves along the cooler, towards the foreground of the image. The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons:

Clinker cooler with Coanda Wing® technology More than 35 years of building clinker coolers and over 600 installations worldwide prove that the IKN cooler is at the forefront of technology. Following the stationary inlet (KIDS®), the …

Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker. At the same time, it provides hot air for the rotary kiln and the decomposition furnace, which is the heat recovery of the firing system. The main equipment.

Clinker cooling. A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.

Clinker Cooler and Pre-Heater Dedusting. The control of clinker fines emissions after the heatexchanger, placed downstream of the clinkercooler,is usually a problem for cementplant managers. The process is characterized by high material abrasiveness, high loads and variable flow ratein normal and maximum conditions.

Providing information for people working in cement plants, those who want to improve the way they work.

Problems with the cooler can result in an unstable kiln, damage equipment, and influence the clinker quality. And excessive wear of cooler parts can lead to inefficient cooling processes and even production stoppages. A regular preventative inspection can eliminate many of the root causes of excessive wear and keep your cooler running smoothly.

The Clinker Cooler is a equipment that can cooling material via the cylinder rotating to drive material processing fully heat exchange with cool air, which have series advantages like good cooling performance, bigger capacity, high operating ratio, energy saving with environmental protection, easy operation and maintenance and long life time.

Clinker Coolers. Functions Hot clinker is to be cooled rapidly to secure a phase composition that imparts adequate cementitious properties. Heat exchange between clinker and air has to be efficient to ensure proper cooling and, at the same time, maximizing the recovery of heat to secondary and tertiary air.
