The CD85 is used primarily for the anchoring of dowel bars as those used in the construction of highways and airport runways and taxiways. It is also used for the bonding of highway pavement markers. The CD85 is ideal for anchoring because a shot-sizing feature enables the operator to select and repeat an ideal resin dosage, Once set, the precise dosage is repeated time after time.
Two bulk hoppers, transfer pumps, and the metering assembly are all located in one cabinet. A Flow Management Kit adds the Remote Trigger Assembly and the Twin Shut-off Valve for a simple remote controlled delivery of metered and mixed epoxy resin. Using plastic disposable mixers, clean-up is nothing more than removing the disposable mixer from the Twin Shut-off valve and disposing of it.
No cleanup is required when using twin dispense hoses because the resin components are not joined until within the disposable mixer. Simply remove and discard the disposable static mixer at the end of the day.
When installing a new nozzle, grease the threads of the mixer mounting nut to prevent resin from bonding to the threads. This will assure easy removal of the nut.
Fill Mode
The resin components enter the Lily epoxy dispenser under pressure from transfer pumps or pressurized tanks. Under this pressure, the separate components flow through open inlet ball valves and into the metering cylinders. As the metering cylinders fill, the resin forces the metering pistons to extend until they reach the main air cylinder end cap. As the pistons bear against the end cap, urethane pads on the piston ends seal off the flow of air venting from the “Fill Sensor” bleed holes. Once both holes are sealed, an air signal is sent that allows the dispense cycle to begin.
Dispense Mode
The air signal from the “Fill Sensor” circuit energizes the COCO Module to close the inlet ball valves, open the outlet ball valves, and pressurize the main air cylinder. The main air cylinder pushes against the metering pistons, pressing them back into their respective cylinders causing the resin to exit the metering cylinders and flow out through the outlet ball valves. The two resin components merge at the static mixer. Once the dispenser stroke is completed, the COCO Module closes the outlet ball valves, opens the inlet ball valves and the main air cylinder returns to the “fill” position.
