Blue smoke systems collect hydro-carbon vapors at mix transfer points.

Load out tunnels capture unwanted vapors.

Fiberbed mist collectors help meet stringent environmental compliances.

Optional weigh batchers can be used on silos without truck scales.

Optional Blue Smoke Packages

Blue smoke (hydro-carbon vapor) is generated at mix transfer points. Blue smoke is actually a haze of petroleum droplets suspended in the air. The blue smoke collection system prevents the vapor from escaping when asphalt is transferred from the mixer to the storage silo. The blue smoke system captures the vapor and uses a fan to transport it back to the drum where it is incinerated by the burner flame. The result is extremely effective. Virtually no blue smoke escapes into the air during silo filling.

Load-out tunnels and fiberbed mist collectors can also be supplied for installations where environmental compliance is a priority.

Low Profile, Electronic Scales

The LPSII truck scale is a totally electronic scale with a low profile. It only needs small foundation pads at each load cell. Weigh sections have checkered-steel deck plates. The scale is wired in conduit. When a silo is used without a truck scale, Astec can provide an optional weigh batcher.

Control All Silo Functions

Motor starts and stops, filling operations and manual loadout are handled from one central location in the control house. The operator also monitors current draws, bin indicators and cone heating information from here. Choose either the latest, state-of-the-art TCII controls utilizing a computer screen, keyboard and mouse, or the traditional analog control panels.

Silo Diameter and Capacity

Astec silos are available in either a 12 ft. or 14 ft. diameter of the following capacities:

Capacities are based on 120 lbs/cu.ft. for mix (0.5 metric tons / cu. meter).
