What is a hot mix asphalt storage silo?

A hot mix silo is an insulated steel silo, usually with a heated discharge cone, that stores finished asphalt between the mixer and the trucks. A skip hoist or slat conveyor carries the mix to the top of the silo, and gates at the bottom load trucks quickly. Silos can be built beside the plant or directly under the mixing tower.

Why add storage silos?

Without storage, the plant must stop whenever no truck is waiting, and each stop and restart wastes fuel. NAPA notes that more than three starts and stops per shift can raise fuel use by 20 to 35%. Silos let the plant run at a steady rate, hold several mix types at once and meet peaks in demand.

How long can asphalt be stored in a silo?

It depends on the mix, the silo insulation and heating, and the specification. Well insulated silos with heated cones keep standard mixes workable for several hours, and longer storage is possible with suitable mixes and checks on temperature and drain-down.

FAQ

Questions buyers ask

What is a hot mix storage silo used for?

It stores finished asphalt so the plant can keep producing while trucks are not at the loading point, and lets trucks load quickly.

How long can hot mix asphalt stay in a silo?

Several hours for standard mixes in insulated silos with heated cones; longer with suitable mixes and temperature checks. The specification for your project sets the limit.

Do silos save fuel?

Yes, indirectly. They reduce plant stops and starts, which NAPA links to 20 to 35% higher fuel use when there are more than three per shift.

Can several mix types be stored at once?

Yes, with several silos or a multi-compartment silo and a distribution chute.
