Some Perspectives to Evaluate the Rotary Drum Cooler

Post  juice on Wed Jul 09, 2014 1:16 am

Cooling machine is one of the important machines of the rotary kiln system and its functions are to cool the clinker from the rotary kiln from 1000-1300℃ to below 200℃ and to improve the quality and grindability of the clinker. Cooler is also called mining machine, mineral machine, mineral equipment, compound fertilizer equipment,cooling liquid. The equipment is used for the cooling of clinker. It can improve grindability and reduce power consumption of grinding and it is a important equipment firing a complete set with rotary kiln system.

The single cylinder cooler is characterized by simple and firm structure and because the hot-air can be returned to rotary kiln, the heating efficiency is very high and the power consumption is fairly less. It's a desirable machine for the cooling of clinker. From thermal and process perspective to evaluate the rotary drum cooler:

1. Recovered more heat;

2. Cooling clinker time is to be shorter, faster, especially between 1250 and 525 degrees;

3. After cooling, the clinker temperature is to be low;

4. Air consumption of cooling per unit mass of clinker is to be less, generally in 2-2.1Nm3/h;

5. Simple structure, convenient operation, easy maintenance, and operation efficiency.

Cooler(mining machinery), mining machine, mineral machine, mineral equipment, compound fertilizer equipment. Cooler mainly used for building materials, metallurgy, chemical industry, cement industry, cool slag, limestone, coal clay, fine chemicals, also be used for fertilizer production lines. Cooler used for the production of compound fertilizer, cool fertilizer with certain temperature and particle size. Use dryer for together can greatly improve the cooling rate, reduce labor intensity and improve the quality, further remove moisture, reduce the grain temperature of fertilizer. At the same time can also be used for cooling other powder, granular materials.
