Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
Dense phase vacuum conveying systems use high capacity vacuum pumps up to 99% vacuum to convey materials from a feed hopper or silo to a receiving vessel or vacuum hopper where the air and product are separated by a filter When the vessel is full the vacuum is isolated and the conveyed product is discharged into the destination silo The product is conveyed through the
