We have great pleasure in providing you with our technical data for a fully self contained tracked mounted screening plant:

                - Extec Robotrac

The main components from a screening perspective are:

• Remote control tipping grid hydraulically operated; wide main conveyor to allow free flow of material to high frequency, scalping and screening arrangement with quick mesh change mechanism. Fully tracked and self-propelling allows total mobility via standard excavator tracks and speedy set through unique design.
• The frame of the unit is specially designed to meet the high demands of screening operations. The track size is 891 with the tracks being driven by two hydromatic hydraulic piston motors.
• The whole unit is powered by a diesel engine primarily a Deutz BFM2012 4 Cylinder 100.4 hp water-cooled.
• A unique feature of the Robotrac is that in comes as standard with many features that are additional extras for many machines. Thus the Robotrac comes complete with:
       - Remote control tipping grid
       - full remote control
       - Vibrating grid
       - stepped grizzly
       - spring loaded scraper
• Screening occurs after oversize material has been rejected by the hopper grid and material has been fed from the grid onto the main conveyor. Three main variables affect the screening capacity:
       - material feeding
       - grid angle
       - screen meshes
• Material feed rate is regulated by the feed control which is situated within the hydraulic control panel. The maximum feed rate may be achieved when the optimum grid angle has been determined.
