Portable cement silos allow the flexibility of temporarily increasing on-site cement storage with very low installation costs.  Portable silos vs. stationary cement silos have a lower center of gravity and cost less.  Cement screws or pneumatic transfer systems can be used to efficiently transfer cement into the concrete batch plant.  Cement silo’s range in size from 25 ton to 150-ton cement storage capacity.  Portable cement silos can also be relocated to another batch plant site as market trends move from one market to the next.  Cement silos are designed to store all different types of cement, fly ash, and slag.  Cement guppy’s or pigs allow additional secondary storage to be added to a concrete batch plant increasing cement storage up to 5X capacity.  Pigs can be installed in series utilizing the same transfer blower.  Pigs can also be fed while simultaneously re-filling the concrete batch plant silo’s.
