Description
Technical Field
[0001] The utility model belongs to the technical field of barite crushing production, and in particular relates to an energy-saving and environment-friendly dust collecting device for barite crushing. Background Art
[0002] Barite is the most common mineral of barium. It is composed of barium sulfate and is produced in low-temperature hydrothermal veins, such as quartz-barite veins, fluorite-barite veins, etc. It often coexists with galena, sphalerite, chalcopyrite, cinnabar, etc. The barite deposits produced in Hunan, Guangxi, Qinghai, and Jiangxi in my country are mostly huge hydrothermal monomineral veins. Barite can also be produced in sedimentary rocks and appear in the form of nodules. It is mostly found in sedimentary manganese deposits and shallow sea muddy and sandy sedimentary rocks. In the residual clay cover layer of weathered residual deposits, it often forms nodules and blocks. During production, large pieces of barite need to be crushed and ground, so a barite crushing device is needed. However, the current barite crushing device will have a lot of dust overflow during processing and discharging, which has a bad impact on the environment and the health of the workers.
