What is the Relationship between Running Speed of Material and Quality of Final Products?

Release time:2017-03-02 06:05:09
   If you have involved in rotary kiln commission site, you may notice that the running speed of materials in rotary kiln is not the same. Why do operators set different rotary speed for materials? What does the influence of materials’ rotary speed on final quality? 
 
   Raw materials in rotary kiln moves from top to bottom. There are two reasons why materials in rotary kiln move. One reason is that the contraction of volume in the calcining process makes upper materials move. The other reason is that the discharge of materials at lower part will lead to the movement of all materials. If the rotary kiln holds proper expansion mouth, the contraction of volume has little impact upon the movement of materials. Therefore, the movement speed of raw materials is mainly decided by how much clinker discharged, namely output capacity of rotary kiln. But, the running speed of materials should be matched with the calcining speed which is relevant to calcining temperature, airflow velocity, heat transfer, size of material, size of fuel and etc.

  Therefore, operators should not only consider the discharge amount and ignore the calcining time. The right operation method is to adjust discharge amount according to specific situation inner the rotary kiln in order to make the moving speed of materials same with calcining speed. Operator can adjust ventilation amount of rotary kiln to improve the calcining speed. In the operation process, operator can also adjust calcining speed by guaranteeing proper size and porosity of pellets. 
 
  We hope that you can get good understanding of the relation between running speed of material and quality of final products.
