Cleaning the air displaced from the silo from cement dust is a mandatory process provided for by a number of regulatory documents at the federal level, for example, “Rules for safety and industrial sanitation in the asbestos-cement products industry,” etc. It is not difficult to imagine what would have happened around concrete plants if not special cement filters were used, installed on silos, providing almost 100% air purification from cement dust. When loading a silo into the atmosphere, up to 5% of the loaded cement “flies out” along with the displaced air. This means that the contents of every 20th cement truck end up in the atmosphere.
ZZBO uses cement filters for the silos of its concrete plants Maxair-24 capacity up to 1800 cubic meters. meters per hour with a polyester filter cartridge. The built-in pneumatic cleaning system returns settled particles of cement dust back to the silo for production use. If necessary, filter cartridges can be replaced in 5 minutes.
