Abstract

The invention relates to a multistage crusher for mining use. The multistage crusher comprises a shell, a feed hopper, an outlet hopper and a rack. The feed hopper is arranged at the upper end of the shell. The outlet hopper and the rack are disposed at the lower end of the shell. A first coarse crushing roll and a second coarse crushing roll which are parallel to each other are arranged inside the shell. Several coarse crushing teeth which are engaged with each other are arranged on the periphery of the first and second coarse crushing rolls. A first fine crushing roll and a second fine crushing roll which are parallel to each other are arranged below the first coarse crushing roll and the second coarse crushing roll inside the shell. Several fine crushing teeth which are engaged with each other are arranged on the periphery of the first fine crushing roll and the second crushing roll. In addition, teeth number of the fine crushing teeth is greater than teeth number of the coarse crushing teeth. A partition plate is arranged inside the shell, and a ventilation channel is formed between the partition plate and a sidewall of the shell. The outside of the shell is provided with an exhaust fan which matches the ventilation channel. Besides, an output end of the exhaust fan is connected to a dedusting box through a pipeline.

Description

technical field [0001] The invention relates to crushing processing equipment, in particular to a mining multistage crusher. Background technique [0002] Crusher is suitable for metallurgy, mining, chemical industry, cement and other industrial sectors. Every year, a large amount of raw materials and reused waste need to be processed by crusher. For example, in a concentrator, in order to separate the useful minerals in the ore, it is necessary to use a crusher to crush the raw ore to the particle size required by the grinding process. It is necessary to use crushing machinery to crush the raw materials to the particle size required by the next step. [0003] In the process of pulverizing materials, the existing crushers fly dust, causing certain pollution to the working environment and affecting the health of the staff. At present, the processing of minerals by crushers is extensive, and some precious minerals cannot be finely crushed. Contents of the invention [000...
