Cement Storage & Cement Transfer Systems

With cement storage needs increasing as cement shortages and production volumes increase, Concrete Producers need a stable supply of raw materials to ensure production rates. RexCon supplies complete cement storage and cement transfer systems to pneumatically transfer cementitious material (cement, flyash, slag, etc.) from a storage silo to an active or main plant silo.

Horizontal Pigs

Easy to transport and load, the horizontal cement storage tank provides extra storage and job-site portability. Not only are they more mobile than cement silos, they have a much higher carrying capacity; 4,000 cubic feet/1,000 bbls. Maximum capacity and portability make Pigs ideal for high volume jobs. Designed to be empty while transported on the road, the single compartment storage tank offers ultimate versatility for your material storage needs. Optional integrated blower packages and installed power panels and wiring provide immediate plug and use capability upon delivery.

Verticle Pigs

Vertical pigs offer bulk cement storage as well, but with a smaller footprint. The vertical pig storage capacity is much more customizable and sizes range from 450 bbls to 1200 bbls.

Cement Transfer Systems

Cement transfer systems typically include a complete backup silo with dust collector, a silo discharge flange, emergency jam gate, rotary vane feeder, discharge adaptor, high pressure air blower, high and low bin level indicators, and control panel. An existing plant air (approx. 30 cfm) and electrical power source is expected to complete the operation of the system, with dry, regulated compressed air assumed to plumb to the vane feeder at approximately 10-15 psi above the pneumatic blower. All pieces of the RexCon-supplied system are appropriately sized to ensure longevity and trouble-free operation.

Typically connected to a plant’s existing 4” or 5” cement fill pipe, the system operates automatically to fill the main silo on absence of a low bin level light on the main batch plant silo. When a high level signal is received from the main silo, the vane feeder shuts off and the cement line is allowed to pneumatically blow until the fill line is purged. The control panel typically includes starters and timers for the rotary vane feeder, high pressure blower, and optional high pressure air compressor (for the vane feeder) and low pressure aeration blower (for the backup silo aeration pads). Manual operation is also built into the control panel.

In principle, the backup silo should be as close to the main silo as possible to increase the rate of transfer, the fill line on the silo and the blower size as large as possible. A single blower can operate multiple storage silos with minimal human intervention, with typical transfer rates in the 12-35 tph range (higher tph is optional but rarely achieved). The entire properly sized system reduces the need for timing cement deliveries as well as decreased congestion and operational costs at the plant.
