The
drag conveyor is driven by an electric motor. It receives hot mix from
the discharge chute of the drum unit and conveys it to the hopper.
The hopper functions as a surge bin. It has an air-cylinder that opens
the gate to dump the hot mix into the bed of a truck.
The drag conveyor and elevated hopper are constructed as a single unit.
A detachable stand supports the hopper and drag conveyor in the upright
position.
The stand has a caged ladder and platform. The pieces can be
transported on a single flat bed trailer (not included).
The drag conveyor is built to last considerably longer than competitive
units. Moreover, it is designed so that parts are easy to replace. Just
compare its features with any other unit on the market:
- Bottom liner of 1/2-inch chromium carbide steel wear plate. (Lasts six times longer than AR plate.)
- Side liners of 1/2-inch AR-360 wear plate.
- Flame-hardened head sprocket, segmented so it can be replaced without removing the drag chain.
- High-alloy head shaft.
- Hardened four-inch, heavy-duty roller chain.
- Conveyor
discharge opening is set back from head sprocket so that the mix is
fully discharged from each flight. This eliminates carry over of
residues that can cause excess wear of the head sprocket and chain.
- Idlers
that support the chain as it returns are extra wide to minimize noise
and vibration and to increase the life of the chain and liner.
