The cooler is one of the important machines in the rotary kiln system. The function of the equipment is to fully exchange heat between the clinker (1000-1200 ° C) from the rotary kiln through the barrel rotating material and air to cool the material below 200 °C. At the same time, it improves the quality and wearability of the clinker, and the air after cooling the material is all put into the kiln, and the secondary circulating air is used to improve the thermal efficiency of the kiln. The cooler has the characteristics of simple structure, high operation rate, and convenient operation and maintenance.

Brief In Cooler

The cooler can be used to treat more than 200 kinds of minerals such as limestone, cement clinker, bauxite, and aluminum hydroxide, and is used in metallurgy, building materials, chemical, cement, construction, refractory, and other industries. Its processing capacity is 2-75t / h.

The material is sent to the hopper by a belt conveyor or a bucket elevator and then fed from the hopper through the feeding pipe into the feeding end. The slope of the feeding pipe is greater than the natural inclination of the material so that the material flows smoothly into the cooler. The cooler cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end of the single-cylinder cooler, and the heat carrier flows out from the lower end, in countercurrent contact with the material, and the heat carrier and the material flow into the cylinder together. As the rotating material of the cylinder is moved by gravity to the lower end, during the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained, so that the hot material is cooled, and then sent out at the discharge end of the cooler through a belt conveyor or a screw conveyor.

1. The single cylinder cooler has a simple structure, high operation rate, convenient operation, and maintenance, and can effectively reduce investment costs.

2. The single cylinder cooler can increase the contact time between the clinker and the cooling air by improving the structure and arrangement of the lifting plate and adjusting the inclination and the rotation speed of the cylinder, thereby fully recovering the heat of the clinker at a lower temperature.

3. The single-cylinder cooler can completely remove the air after cooling the material into the kiln, and as the secondary circulation air, the thermal efficiency of the kiln is improved.

4. It is developed with advanced technology at home and abroad, and has the advantages of energy saving, high efficiency and economical environmental protection.
