Self-Erect Surge Silo

Overview

The NTEP Certified Astec Self-Erecting Surge Silo offers asphalt mix producers exceptional capabilities and advantages not found elsewhere. An optional oil-sealed gate and grease-sealed batcher provide industry-leading storage in a portable silo. A steeper cone angle helps achieve optimal mass material flow. The entire column of mix evenly flows through the cone thanks to the steeper angle of the cone. There is no mix buildup on silo walls and mass flow loadout minimizes mix segregation in the cone. The silo and drag share a common chassis and are erected together using hydraulic cylinders.

Applications

Asphalt Mixing

A thermal mixing process is required to turn aggregates and liquid AC into an asphalt pavement mix for road construction. This makes an asphalt mixing plant necessary for road construction. The complete line of Astec asphalt mixing plants, and its range of capacities and features, gives you the choices and flexibility to create your optimum solution.

Features

NTEP Certified

The silo weighing system utilizing load cells is NTEP Certified to ensure accurate ticketing at load-out.
True Portable Storage Capability

An optional oil-sealed gate and an enclosed silo top equipped with a grease seal prevent oxygen penetration to allow longer-term storage. The oil-seal gate and grease seal batcher in conjunction with insulation provide true overnight storage capabilities. An optional electric heat blanket on the cone and gate is available for this fully-insulated silo. 1/4” AR liners above and below the cone joint enhance longevity. Silo and batcher are both equipped with a set of level-indicating bindicators.
Self-Erecting Surge Silo Drag

The 36” drag includes liners for durability. Optional electric heat helps ensure flawless operation at start-up and a bottom drop out chute accommodates bypassing when needed. For enhanced safety and maintenance ease optional stairs can be mounted to the drag conveyor. Remove grease points for greaseable bearings on drag are easily accessible.
Easy Set-Up

A single set of multi-stage cylinders lifts the drag and silo into operating position simultaneously without the need of a crane. Large landing pads accommodate set-up on compacted dirt. Once in operating position, the truck drive provides a full 12 feet of clearance.
Steeper Cone Angle

A steeper cone angle helps achieve optimal mass material flow. The entire column of mix evenly flows through the cone thanks to the steeper angle of the cone. There is no mix buildup on silo walls, and mass flow loadout minimizes mix segregation. Mass flow occurs when mix flows out across the entire silo cross-section and that only happens with a steeper cone angle.
