How do crusher machine prevent Dust? According to the characteristics of dust sources were used for dust suppression sprinkling, spraying dust cover dust and other wet dust control measures. In freezing, wet dust dryland unconditionally or after wet dust mainly the standard, you need to adopt an integrated approach to mechanical removal or mechanical removal and dust while wet and used. Mechanical removal of equipment to fit the characteristics of the mine, requiring a simple structure, are small and compact, easy migration, moisture durable. At each operation step integrated dust control measures still fail to meet requirements, the need for personal protection. (1) rock and dust. Priority to high collection efficiency of wet rock. When not have wet drilling conditions, can be dry-catching rock dust, dry dust catching drill into the rock mouth to catch the dust cover dust extraction dust or smoke in the bottom of the hole in two forms. Not a lot of water under the circumstances, can foam dust, pressed into the bottom of the hole is about foam or spray orifice, or the dusty air is introduced into the foam filter purification. (2) blasting dust. Dust the largest amount of dust production time blasting ore concentrate. The main measures are spray sprinklers and dust seal blasting. Spray sprinklers often start blasting wave sprayer, water purification and water curtain air ejector and so on. (3) shipment of dust. Ore stacked rock loader, loaders, scrapers, tub, belt conveyor and ore chute, loading and other operations are generating a lot of dust, spray watering can, sealed ventilation and other measures to prevent dust distribution. (4) broken dust and perforation dust. Quarry crusher equipment for all kinds of dust generated by the work, the device closed on the basis of wet dust can be combined with mechanical dust removal measures. Mechanical dust purification equipment using baghouse or wet scrubber. Broken underground cavern dust should use wet scrubbers, when exhaust removal system can not row back to the wind tunnel or the ground, but only when in situ emissions, exhaust subject to high efficiency filter processing. |
