Cement Bulker Unloading System

Product Overview

Product Details: A Cement Bulker Unloading System is a specialized pneumatic conveying system used to unload dry bulk cement or fly ash from road tankers (bulk carriers) into storage silos. It ensures efficient, dust-free, and continuous transfer of powdery materials using compressed air. The unloading system operates on pneumatic pressure generated by a Roots blower (usually a twin-lobe type): Compressed air is generated by the blower and sent to the bulker’s pressure vessel. The air enters the bulker tank through a pipeline and aeration system, fluidizing the dry cement/fly ash inside. The fluidized material is then pushed out of the tank and into the delivery pipeline by the pressure. It is conveyed pneumatically through the pipe to the storage silo, often passing through a butterfly valve, non-return valve, and sometimes a diverter valve. This system can unload a typical 25–30 ton bulker in about 30–60 minutes, depending on the blower capacity and pipeline design. Discharge Capacity: ~30 TPH (tons per hour), depending on setup Pressure Range: 0.6 to 1.0 bar (g) Power Requirement: 15–40 HP (typical) Mounting: Stationary skid-mounted or mobile trolley-mounted Operation: Electric, diesel engine, or PTO (vehicle-powered) Unloading cement, fly ash, or other fine powders from: Cement bulkers Fly ash tankers Bulk material carriers Widely used in: Ready-mix concrete plants Cement terminals Construction sites Power plants (for fly ash) Fast and efficient unloading Dust-free and environmentally friendly Minimal manual intervention Can handle long-distance conveying (up to ~50 m) Compact and rugged design Low maintenance requirement
