Transportable Site Silo

A combined cement silo and water replenishment station to enable Armcon Mobile Mixers to be refilled quickly, reducing off road time. The design contains several features that ensure that the operatives achieve quick turnaround times.

The hopper has a capacity of 40 tonnes of cement (density 1.2), and is loaded under pressure from bulk road tankers. A blow-up pinch valve prevents damage from overloading during delivery. Audible and visual high and low level alarms are provided. A pulsed aeration system aids free flow of cement to the silo auger.

A ladder gives access to the top of silo and the swing down bridge that facilitates access over the lorry hatches. Both areas are guarded by hand railings and security chains. Sited within this area is a reverse jet air filter system that prevents leakage of cement dust to atmosphere during loading and operation, a pressure relief valve and an access man hole.

An inclined auger transfers the cement from the horizontal silo auger to the flexible outlet that fits into the mixers cement hopper access lid. A hand held control unit provides independent control over both cement augers and the water pump from the access bridge. External lighting can be provided for night-time operation.

The 4,500 litre glass reinforced fibre water tank and 300 litre/minute pump, connects to the mixer via a quick release hose coupler to replenish the on-board water tank.

The silo is designed to fall outside of planning regulations, and can be sited at any convenient point providing vehicle access, electricity and water.
