Description

Technical Field

[0001] The utility model relates to the technical field of limestone processing, and particularly relates to a proportioning mechanism for limestone calcination. Background Technique

[0002] Quicklime is mainly prepared by calcining limestone, and the main means of limestone calcination is to adjust the heat input. Generally, the heat source for calcining limestone is coal. By adjusting the mass ratio of limestone and coal, the limestone can be completely calcined. During the proportioning process, proportioning equipment is required.

[0003] In the existing proportioning equipment for limestone calcination, during the discharging process after proportioning, some limestone powder and coal powder are likely to adhere to the inner wall of the mixing bin, which is likely to cause incomplete discharging and is not convenient for the subsequent use of the equipment. For this reason, we propose a proportioning mechanism for limestone calcination. Content of the Utility Model
