The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Maximize production capabilities with an advanced short-term silo system.
Engineered for maximum performance and manufactured for years of reliable service, the Astec silo system is built to provide high efficiency at a low cost. These silos are made to withstand today’s high production requirements and are stacked with features not found on competitive equipment.
System capacities from 100-ton single silos to 3,000-ton multiple silo systems. Custom arrangements can be configured for your requirements.
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.
A horizontal traverse conveyor transfers asphalt mix from a drag conveyor or bucket elevator to additional silos. The traverse conveyor is equipped with motors and coupled to in-line, heavy-duty reducers.
The transfer conveyor features a strong, all welded, U-box frame that eliminates cracking potential and improves the structural integrity. The heavy-duty chain arrangement includes reinforced flights. High-chrome blend liners protect the floors and side walls from wear. A heated floor with insulated heat covers helps prevent material build-up during start-up and assists in keeping the floor clean. Includes return-run idlers and adjustable take-up assemblies.
Bolt-On Divert Gate
The transfer conveyor includes an exclusive bolt-on divert gate assembly with liners. No more welding gates to shafts inside of the transfer body. The divert gate is easily replaced by simply unbolting the divert gate from the transfer conveyor. This allows replacing the highest wear area on the transfer conveyor without welding or torching and without having to also take the transfer down to the ground. The divert gates are lined with wear resistant plates for added life and have an access door for clean out.
Mix Level Indicators
Each silo has low level and high level indicator rods that extend through the top deck. The design eliminates weak points and allows service of the rods from the deck.
The low and high level indicators measure mix level and communicate that information to the control house. The high level indicator signal prevents overfilling the silo. The low level indicator prevents running the silo completely empty so that when you load from the batcher you are loading onto material rather than the cone.
Batcher with Built-in Splitter
The batcher features a built-in splitter to protect the leading edge of the gate and minimize maintenance. The splitter divides the flow of material as it drops to help reduce segregation.
