Crushing processing system of limestone for calcining in lime kiln

Abstract

A crushing processing system of limestone for calcination of a lime kiln comprises a feeding device, a first crushing device, a second crushing device, a first screening device, a second screening device and a third screening device, the feeding device is connected with the first crushing device, the first screening device is located between the first crushing device and the second crushing device, and the third screening device is located between the first crushing device and the second crushing device. And the second screening equipment is positioned between the second crushing equipment and the third screening equipment. The comprehensive utilization effect of resources is fully considered, and multi-product comprehensive layout and crushing and grinding joint production are adopted, so that the produced limestone is moderate in particle size, uniform in particle and full in particle shape, and the quality of the lime in the later period is facilitated.

Description

technical field [0001] The invention relates to the technical field of lime kiln calcination technology, in particular to a limestone crushing and processing system for lime kiln calcination. Background technique [0002] Lime (quick lime) is widely used in metallurgy, construction, chemical industry, environment, agriculture and other fields. The production process of lime is essentially the process of thermal decomposition of calcium carbonate. At present, the technology of limestone calcination to produce active lime in my country is mainly rotary kiln and shaft kiln. In practical application, the limestone used for calcining in lime kiln is generally mined outside or piggybacked by the crushing line that produces building aggregates. There is no special process or equipment to serve raw materials for lime kiln. Limestone required for lime kiln firing The particle size requirement is 40-80mm; the limestone particle size required for burning lime in the rotary kiln is 20-...

AI Technical Summary

Problems solved by technology

[0006] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a limestone crushing and processing system for calcining limestone in a lime kiln, which solves the problem of poor particle shape, uneven particle size, fine particles and powder in traditional lime kilns. Too much, leading to the technical problems of raw lime burning, too little and waste of resources, improving the quality of lime calcination and the utilization rate of ore and resource development and utilization
