Environment-friendly type ore material pulverizing device

Abstract

The invention discloses an environment-friendly type ore material pulverizing device. The environment-friendly type ore material pulverizing device comprises a pulverization box and a dedusting box. A filter plate is arranged in a middle cavity of the pulverization box in a fixed and erected manner. A pulverization cavity and a lifting cavity are formed in an upper cavity of the pulverization box, and the pulverization cavity is partitioned from the lifting cavity through a partition plate. A blanking cavity is formed in a lower cavity of the pulverization box. A venturi tube mounting plate is arranged in a middle cavity of the dedusting box in a fixed and erected manner. Multiple venturi tubes are uniformly mounted on the venturi tube mounting plate. A dust filtering bag is arranged at the bottom of each venturi tube. An annular pipe is arranged in an upper cavity of the dedusting box in an erected manner. Multiple air outlet pipes are uniformly arranged on the lower surface of the annular pipe in a communicating manner. The upper portion of a cavity body of the pulverization cavity is arranged to communicate with the lower portion of a cavity of the dedusting box through a conveying pipeline. The environment-friendly type ore material pulverizing device is simple in structure, convenient to use and capable of fully pulverizing ore raw materials; and in addition, in the ore raw material pulverization process, the working environment cannot be polluted by dust, and comfort of the working environment is guaranteed.

Description

Technical field [0001] The invention relates to a crushing device, in particular to an environmentally-friendly ore material crushing device. Background technique [0002] With the continuous development of the mining industry, ore will be divided into different grades according to different parameters such as particle size and composition. In particular, particle size is an important criterion for measuring ore; too large or too small particles affect the price of ore, and slag Materials such as ore and ore are frequently used building materials in the construction process, but ordinary stone is generally larger in size and does not meet the requirements of building stone. [0003] At present, ore with too large particles needs to be crushed into smaller ore. At present, workers generally use hammers to slowly crush larger ore. This requires a lot of manpower, and there is often insufficient crushing during crushing. , And workers will inhale a lot of dust when crushing ore, whic...

[0002] With the continuous development of the mining industry, the ore from mining will be divided into different grades according to different parameters such as particle size and composition, especially the particle size is an important criterion for measuring ore; too large or too small particles will affect the price of ore, and slag , ore and other materials are frequently used building materials in the construction process, but ordinary stones are generally large in size and do not meet the requirements of building stones

[0003] At present, ore with too large particles needs to be crushed into smaller ores. At present, workers generally use hammers to slowly crush larger ores. This requires a lot of manpower, and there is often insufficient crushing during crushing. , and workers will inhale a large amount of dust when crushing ore, not only the work efficiency is low, but also seriously affect the health of workers
