There are many types of kilns, and their functions are different, which can meet different production requirements of users. However, many users of rotary kilns and shaft kilns are still very familiar with it. Let's understand by comparing the two aspects.
The difference between the rotary kiln and the shaft kiln is mainly the perspective of the quality and structure of the finished product:
For rotary kilns and shaft kilns, it is generally believed that the quality of lime produced by rotary kilns is better, and limestone with smaller particle size can be calcined; while the quality of lime produced by shaft kilns is generally slightly lower than that of rotary kilns.
Shaft kilns can use fuels with lower calorific value to make full use of secondary energy generated by metallurgical plants. They have a small footprint, low investment, low heat and electricity consumption, and product quality can meet production requirements. Judging the successful shaft kilns introduced in China, the quality of its products has met the requirements of metallurgical production. However, the general structure of the shaft kiln is relatively complicated, and the operation requirements are higher than that of the rotary kiln.
Rotary kilns are mature in terms of technology and production operations. The structure is relatively simple, the operating costs are low, the number of operators is small and easy to control, and the quality of the finished products is also high.
In general, the rotary kiln is better than the shaft kiln in terms of use cost and quality of finished products, and it is relatively simple in operation and structure, and can also save the cost of operating workers.
