ore crushing unit

Abstract

The invention relates to an ore crushing machine unit, which comprises a jaw type crushing machine (1), a hammer type crushing machine (2), a sealing cabin (3) and a material collecting cabin (4), wherein the jaw type crushing machine (1) is arranged above the hammer type crushing machine (2); the hammer type crushing machine (2) is arranged on the top of the sealing cabin (3); the material collecting cabin (4) is arranged in the sealing cabin (3); an air suction hole is formed in the sealing cabin (3) in a direction along the tangential line of the column surface. The ore crushing machine unit has the advantages that an inside dust removal mode is adopted by the machine unit; the dust explosion problem can be effectively avoided; environment is protected; the safety is high.

Description

technical field [0001] The invention relates to an ore crushing unit, which is mainly used for crushing alloy ores. It belongs to the technical field of mechanical equipment. Background technique [0002] At present, the technology and equipment of domestic alloy production have reached the world's advanced level, but the process equipment and production process of alloy powder preparation are very backward, which not only pollutes the environment, but also causes huge economic losses to enterprises due to dust explosion accidents, so How to prevent dust explosion has become the primary issue in this industry. [0003] Existing enterprises use open-air or semi-open-air methods to solve the problem of dust explosions, discharge dust into the air, and use air to dilute the concentration of dust to avoid dust explosions, but this method will cause environmental pollution; and Some enterprises use nitrogen protection to solve the problem of dust explosion, but the cost of this...

Problems solved by technology

[0002] At present, the technology and equipment of domestic alloy production have reached the world's advanced level, but the process equipment and production process of alloy powder preparation are very backward, which not only pollutes the environment, but also causes huge economic losses to enterprises due to dust explosion accidents, so How to eliminate dust explosion has become the primary problem in this industry

[0003] Existing enterprises use open-air or semi-open-air methods to solve the problem of dust explosions, discharge dust into the air, and use air to dilute the concentration of dust to avoid dust explosions, but this method will cause environmental pollution; and Some enterprises use nitrogen protection to solve the problem of dust explosion, but the cost of this method is huge, and the maintenance cost is high; some enterprises adopt the method of external dust removal, that is, install dust removal devices above the crusher or above the discharge port , but the dust removal effect of this method is poor, and it cannot fundamentally solve the problems of dust explosion and environmental pollution
