FOAMED ASPHALT SYSTEM FOR MIXING BARREL DESIGNED FOR PRE-COATED CHIPS
The BearCat foaming system installed on an existing batch plant can increase your profits by reducing the amount of asphalt required to pre-coat.
Hot asphalt greatly expands when foamed to cover aggregate evenly then shrinks. The result is perfectly covered aggregate without the excess asphalt that forms clumps.
The spraybar system when mounted in your drum replaces the existing feed pipe. During foaming opperations the asphalt and water is metered by a computerized control panel installed in the control house through an externally mounted asphalt pump.
The small spread rate required for precoating chips is dificult to control with existing batch plant pumpning systems, thus the reason for the external pump. The external pump is mounted in parralell with the existing system so that returning to normal asphalt production can be a simple twist of a couple valves.
Spraybar Replaces Feed Tube
The spraybar in the drum is capable of delivering the required asphalt output for normal production.
