Mine material crushing system of dust remover for perforation, drilling, blasting, loading and crushing process have dust treatment in mining opencast mining or underground mining emissions, serious pollution of working environment and atmospheric environment. No dustproof measures in dry drilling operation, the dust concentration per meter. Up to hundreds or thousands of milligrams. No dust control measures, dust concentration per meter. Up to thousands of mg.
The comprehensive dust control technology of mining dust removal is mainly to spray and dust. According to the characteristics of the dust source, the wet dust control measures such as spraying dust suppression, spraying dust, covering dust and other wet methods were adopted. In the freezing and water shortage area, when the water is not required to be used in wet dust or dust, it is necessary to adopt the comprehensive method of mechanical or mechanical dust removal and wet dust collection. Mechanical dust removal equipment to be suitable for mine characteristics, the requirements of simple structure, compact size, easy to transport, moisture and durable. In the operation process of the comprehensive dust control measures are still not up to the requirements, the need to take personal protection.
Feed 1, mine raw material crushing system for dust collector of raw material ore, ore, limestone, dolomite, bauxite, coal and other crusher crusher or port, discharging port, the upper vibrating screen and belt conveyor transfer points and other parts of a closed device is arranged or the dust collecting cover, feeding at the transfer point should be established double layer sealed cover. The dust covered with airtight cover equipment, or make a dust collecting chamber, the uniform formation of vacuum cover, avoid dust escaping or open suction hood form suction trap air, dust will be exposed in the narrow area of control within the scope of the articles by trapping dust airflow pumped out by the dust collector. Purified by the exhaust tube (or stack) into the atmosphere.
2, blending slot discharge machine and slot dosing station should take measures to dust. The dust tank unloader can be generated by moving air ventilation slots or vehicle type dust collector, or a large volume sealed cover. Double layer sealed cover is suitable for the dust to be produced by the quantitative discharging device in the groove. The separate dry type dust collection system should be set up in the process of mixing and mixing the mixing tank.
3, coal crushing and conveying dust removal system should take anti explosion measures. Filter bag filter bag filter, filter material should have anti-static function; system and equipment should be static grounding, and set the venting device. An insulation or heating measures should be taken.
Exhaust dedusting system 4, raw material yard including crushing, sieving and dust removal system, limestone crushing, sieving and dust removal system, aluminum ore crushing and crushing coal dust removal system, dust removal system. For the production of dust concentration, dust and similar equipment working system of the same dust, as far as possible the use of centralized dedusting system, the management is convenient, such as limestone crushing, sieving and dust removal system up to dozens of dust in a big system. Small dispersion system can be used. A variety of dust removal system in the use of dry efficient bag filter
