Description

Technical Field

[0001] The utility model belongs to the technical field of mullite crushing, in particular to a mullite crushing device with a dust reduction function. Background Art

[0002] Mullite is a high-quality refractory raw material. This relatively rare mineral is formed when aluminum silicates are heated at high temperatures. Natural mullite crystals are slender, needle-shaped and arranged in radial clusters. Mullite ore is used to produce high-temperature refractory materials.

[0003] A Chinese patent discloses a raw material pulverizing device for mullite brick production (CN213286951U). The device comprises a pulverizing box with a feed hopper fixedly connected to its top. Two symmetrically arranged pulverizing plates are rotatably connected to the inner sidewall of the pulverizing box. Two first rotating shafts extend through the inner sidewall of the pulverizing box and are rotatably connected thereto. First cams are sleeved onto the outer sides of the first rotating shafts, and the two first cams respectively contact the two pulverizing plates. The present invention utilizes the interaction between the pulverizing box, the pulverizing plates, the first rotating shaft, the first cams, a drive mechanism, and a pulverizing mechanism. The drive mechanism drives the first cams to rotate, which in turn drives the two pulverizing plates to rotate. The two pulverizing plates cooperate to initially pulverize the raw material, improving pulverization efficiency. Subsequent pulverization efficiency is further enhanced by the pulverizing mechanism, effectively improving mullite brick production efficiency. Current pulverizing devices generate a large amount of dust when pulverizing mullite. This dust floats in the air, polluting the air and causing harm to the operator. Therefore, a mullite pulverizing device with dust reduction function is provided. Utility Model Content
