Just lately, dust-collecting fan is aging, so many sealing units of sand making machine factories have different degrees of injury, and dust collecting result has fallen. But in recent years, dust amount is also developing, a lot of stone factories received punishment from environmental safety departments, and have been ordered to load the factory shed to enclose full stone production lines, for prevent dust rising in to the air or affecting the surrounding air.
Shed stone factories really are a tendency of sand making machine factory, particularly stone materials factories all-around cities. Shed aggregate plants not simply can effectively manage dust pollution, but stay clear of noise pollution, so some area governments are actively to realize the tendency. The key gear of exploration factories involves the feeding program, crushing and screening method and sand washing procedure, and also the feeder and vibrating screen are often named machine, which suggests that almost all with the mineral components are made from the comparable mining makers, along with the crushing machine is various. There are several kinds of crushing machine from the sand production line, whose efficiency characteristics and attributes are exclusive and unique from one another. So the investor must decide on the mining machines in accordance towards the diverse sensible demand.
Stone production line normally contains jaw crusher, impact crusher, belt conveyor and vibrating sieve, however the dust volume of vibrating display and counterattack impact crusher is quite serious, so installation the enclosed dust-extraction unit is important. But every one of these enclosed dust-extraction services will make loud noise, and shed plant can properly lessen noise diffusion and dust just isn't divisible to become quickly spread on the surrounding environment. Stone factories around the cities will visit the shed mode, and is in even further investigate and improvement from the configuration and style and design of shed stone production line, and strive to investigate and develop crusher tools with dedusting and noise control amenities, so as to try and do the marketing do the job of new environmental and friendly stone manufacturing line.
