A limestone screening device

Abstract

The invention discloses a limestone screening device. The key points of its technical scheme are: it includes a lower material barrel, a first material conveying pipe, a dust conveying pipe and a material feeding device. The high end of the pipe is connected to the lower material barrel, the low end of the first feeding pipe is above the feeding device, the dust delivery pipe is installed on the side of the feeding pipe facing the ground, and the first feeding pipe faces the ground A plurality of filter holes are opened on the side wall of the first feeding pipe, and the plurality of filter holes are evenly distributed on the corresponding side wall of the first feeding pipe, and a dust collecting groove is arranged under the end of the dust sending pipe close to the ground. Most of the powder enters the dust delivery pipe through the filter holes, and then is collected by the dust delivery pipe and sent to the dust collection tank, so that the limestone powder can be recycled and the dust phenomenon of the limestone in the subsequent crushing process is alleviated. ; The dust delivery pipe is arranged obliquely together with the first material conveying pipe to reduce the land occupation in the horizontal direction.

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
