Limestone screening device

Abstract

The invention discloses a limestone screening device. According to the technical scheme, the limestone screening device is characterized by comprising a discharging cylinder, a first material conveying pipe, a dust conveying pipe and a feeding device, wherein the first material conveying pipe is arranged in the mode of leaning on the ground, the end, with the larger height, of the first material conveying pipe is connected with the discharging cylinder, the end, with the smaller height, of the first material conveying pipe is located above the feeding device, the dust conveying pipe is mountedon the side, facing the ground, of the first material conveying pipe, a plurality of filter holes are formed in the side wall, facing the ground, of the first material conveying pipe, the plurality of filter holes are uniformly distributed on the corresponding side wall of the first material conveying pipe, and a dust collecting tank is arranged below the end, close to the ground, of the dust conveying pipe. Most of powder enters the dust conveying pipe through the filter holes, then is collected through the dust conveying pipe and is sent into the dust collecting tank, so that the limestonepowder can be recycled, and the flying dust phenomenon of limestone in the subsequent crushing process is reduced; and the dust conveying pipe is obliquely arranged along with the first material conveying pipe, so that the occupied area in the horizontal direction is reduced.

Description

technical field [0001] The invention relates to the technical field of limestone processing equipment, in particular to a limestone screening device. Background technique [0002] In modern industry, limestone is the main raw material for making cement, lime, and calcium carbide, and its annual consumption is huge. At present, the battle of my country's cement enterprises for the market can also be said to be a battle for limestone resources, so many enterprises will take advantage of limestone resources as one of the measures to realize their own development strategies. On the other hand, these enterprises set out to study how to reduce the waste of limestone in the process of processing, so as to improve the utilization rate of resources. [0003] Limestone will produce powder due to collision during the mining and transportation process, and these powders are transported to the limestone processing site together with the limestone raw material for processing. Limestone ...

AI Technical Summary

Problems solved by technology

[0003] Limestone will produce powder due to collision during the mining and transportation process, and these powders are transported to the limestone processing site together with the limestone raw material for processing. Limestone raw materials will be turned over, resulting in limestone powder dust phenomenon, which not only pollutes the production environment, but also causes waste of limestone resources
