A kind of lime powder preparation method

Abstract

The present invention relates to a lime powder preparation method, which adopts a lime powder preparation device. The lime powder preparation device includes a bottom frame, a screening mechanism, a conveying mechanism, a pulverizing and drying mechanism and a collection basket, which can solve the following problems: a After the lime powder is crushed, ground and calcined, during the storage process, due to the strong water absorption of the lime powder, the lime powder may absorb water and cause a hardening phenomenon, which will affect the subsequent mixing of the lime powder and other building materials. The use effect of powder, b In the traditional limestone preparation device, during the secondary grinding process of lime powder, the distance between the crushing frame and the cylinder wall cannot be adjusted, and it cannot be adjusted for the agglomeration of lime powder plates of different specifications. The pulverization treatment has low applicability, and during the grinding process, the surface of the cylinder wall is easy to adhere to the lime powder.

Description

technical field [0001] The invention relates to the field of lime powder preparation, in particular to a preparation method of lime powder. Background technique [0002] Lime powder is a construction industrial raw material produced by crushing, grinding and calcination of limestone. The processed lime powder is a white powdery solid and is widely used in housing construction, road infrastructure, and industrial production. In other occasions, during the actual storage of lime powder, the treated lime powder will cause moisture due to water absorption during storage. [0003] At present, the lime powder has the following problems in the preparation process: a. After the lime powder has been crushed, ground and calcined, during storage, due to the strong water absorption of the lime powder, the lime powder may absorb moisture and cause compaction, which will affect the subsequent lime. The uniformity of powder mixing with other building materials affects the use effect of li...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a method for preparing lime powder, which can solve the following problems in the preparation process of lime powder: a. After lime powder is crushed, milled and calcined, during storage, due to the strong water absorption of lime powder, lime The lime powder may absorb moisture and cause compaction, which will affect the uniformity of the subsequent lime powder mixed with other building materials and affect the use effect of the lime powder. bIn the traditional limestone preparation device, the lime powder is ground during the secondary grinding process The distance between the powder crushing frame and the cylinder wall cannot be adjusted, and it cannot be crushed for the agglomeration of lime powder boards of different specifications. The applicability is low, and during the grinding process, lime powder is easy to adhere to the surface of the cylinder wall. Timely treatment is easy to cause sticking on the cylinder wall, which affects the grinding effect
