Crushing and classifying equipment for limestone processing

Abstract

The crushing and classifying equipment for limestone processing comprises a crushing device body, a feeding port is fixedly installed at the upper end of the crushing device body, a classifying box is fixedly installed at the lower end of the crushing device body, and a first screening plate is movably connected to the inner side of the classifying box; by arranging a cam mechanism, a first material screening plate, a second material screening plate and a third material screening plate, after stone is crushed, a servo motor in the cam mechanism works to drive a cam body to rotate, the cam body rotates and rolls with a round wheel, and a reset spring and a reset plate are matched with each other; the first material screening plate and the second material screening plate are driven to vibrate left and right, stones with different sizes are screened out through the first material screening holes, the second material screening holes and the third material screening holes, the stones can be classified and screened conveniently, the subsequent secondary stone classification step is avoided, and the screening efficiency is improved. And the production and processing efficiency of collecting and using the stone is greatly improved.

Description

technical field [0001] The invention relates to the field of limestone processing, in particular to a crushing and classifying equipment for limestone processing. Background technique [0002] Limestone, referred to as limestone, is a carbonate rock mainly composed of calcite. Sometimes it contains dolomite, clay minerals and detrital minerals. It has gray, off-white, gray-black, yellow, light red, brown-red and other colors. It is generally not hard and has a violent chemical reaction with dilute hydrochloric acid. Limestone is an important industrial raw material in metallurgy, building materials, chemical industry, light industry, construction, agriculture and other special industrial sectors. With the development of the steel and cement industries, the importance of limestone is bound to increase further. [0003] Limestone needs to be crushed when it is in use. The equipment in the prior art cannot classify the broken limestone particles when crushing limestone. When ...

AI Technical Summary

Problems solved by technology

[0003] Limestone needs to be crushed when it is in use. The equipment in the prior art cannot classify the broken limestone particles when crushing limestone. When in use, it needs to be classified again, which delays work efficiency. A large amount of dust will be generated when it is broken, which seriously affects the surrounding air sanitation
