The CSP-M Unit is an mounted unloader, which can be used for reloading directly from storage silo to bulk trucks without any need for separate distribution hoppers. The CSP Unit can be placed on dock level, which uses a screw conveyor and airslide loading system. Or the CSP Unit can be placed above the receiving bulk truck and then the trucks can be loaded by gravity loading through the loading bellows. The Continuous Suction Pump Dock Mounted unloaders handle powdery materials such as cement, alumina, fly ash, gypsum, etc. without causing any dust nuisance. The vacuum system combined with the long reach of the suction arm enables dust-free operation. All CSP-M units are available with an long and highly manoeuvrable suction arm allowing uninterrupted unloading from the hold of the ship, whether a coaster or an inland vessel. The suction arm and the vacuum system pick up all the cargo right down to the bottom of the hold, thus minimising clean-up and maximising efficiency.
