Calcining device capable of separating powder from crushed stone after crushing of limestone

Abstract

The invention relates to the field of lime, in particular to a calcining device capable of separating powder from crushed stone after crushing of limestone. The technical problem is to provide the calcining device capable of separating the powder from the crushed stone after crushing of the limestone. According to the technical scheme, the calcining device capable of separating the powder from the crushed stone after crushing of the limestone comprises a bottom plate assembly, a crushing unit, a powder separating unit, a calcining unit and a control screen. The bottom plate assembly is connected with the crushing unit. According to the device, large blocky limestone is crushed, the crushed limestone is conveyed to a designated position, and due to the fact that more powder is generated after crushing, in order to guarantee the later product quality, the powder generated after crushing is separated from broken stone, the powder is collected, then the broken stone is fed into a furnace in batches for calcination, and powder removal is accelerated to reach the temperature required by the calcining furnace, so that resource waste is reduced, and the later product quality is improved.

Description

technical field [0001] The invention relates to the field of lime, in particular to a calcining device for separating powder and crushed stone after crushing limestone. Background technique [0002] Limestone, referred to as limestone, is a carbonate rock with calcite as the main component, sometimes containing dolomite, clay minerals and detrital minerals, with colors such as gray, gray white, gray black, yellow, light red, brown red, etc., and the hardness is generally different. It is large and has a violent chemical reaction with dilute hydrochloric acid. It is classified as a sedimentary rock according to its origin. Limestone is widely used. It is an indispensable raw material in various sectors of the national economy and people's lives. It is the main raw material for burning lime and cement. and fluxes for steelmaking. [0003] At present, in the prior art, in the process of calcining limestone to make quicklime, the limestone is directly crushed, and after being c...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the current situation, in the prior art, in the process of calcining limestone to make quicklime, the limestone is directly crushed, and after the crushing, it is directly sent to the calciner, and after being heated to a certain temperature, quicklime is made. This method, Because limestone is easy to produce powder after crushing, and if the powder is not removed, it is easy to cause the temperature in the calciner to reach the required temperature, resulting in waste of resources, and direct calcination, resulting in incomplete heating of limestone, which in turn affects the quality of later products. Disadvantages, technical problems: provide a calcining device for separating powder and crushed stone after crushing limestone
