Grate Cooler in Cement Plant Cement Clinker Cooler

The grate cooler is a type of clinker coolers, it plays an important role in the clinker manufacturing process. The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater.The performance of the grate cooler will directly affect the production efficiency, energy consumption, and

Grate cooler and method of cooling Krupp Polysius AG

What is claimed is: 1. A grate cooler adapted to receive material from the discharge end of a rotary kiln arranged at right angles to such cooler, said cooler comprising an elongate thrust grating having a material receiving end below said kiln for receiving material discharged from said kiln, said grating having a vertical plane passing through the longitudinal axis of said grating and spaced

cooler grates Magotteaux

2018-6-7  cooler grate plates depend to a large extent on their location in the cooler. Magotteaux therefore addresses each zone in a different way in order to develop and optimize solutions for each one. 1. The hot zone (or drop zone). 2. The intermediate zone. 3. The cold zone. 1. The hot zone. Particular constraints: • High temperatures of clinker.

Research on Control Mechanism Model of Grate Cooler

As shown in Fig. 1, high temperature clinker get into grate cooler from rotary kiln. Clinker layer moves slowly on grate bed. Cooling air blows into the clinker layer vertically from the bottom of the clinker, permeates and diffuses in the clinker to cool the red-hot clinker. Cooling air becomes hot air after exchanging heat energy with

Optimization Design of the Grate Cooler Based on the

As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization. Then, the grate cooler was simplified into a series-connected heat exchanger network by power flow method.
