AMOREF PTY LTD DREDGING EQUIPMENT: CHALLENGER DREDGE CD 1 IN SOUTH AFRICA

POA. A Amoref suction dredge is basically a device which is designed to suck gravel from the bottom of a river, pull it up through a hose and run it over a sluice box. In the sluice box, any gold which is present becomes trapped and the lighter materials such as sand and gravel move down and out of the sluice box and back into the river. The operator guides to the nozzle of the hose to suck the rocks and gravel which he desires to process off the river bottom. A small 5 to 15 HP engine is used to pump water which creates the suction that pulls the sand and gravel up through a hose and into the sluice box. The suction in the hose is actually created through a Venturi effect by pumping high pressure water through a jet. The fast-moving water creates the suction in the jet. This way the sand and gravel does not actually go through the pump which would quickly wear it down. There are two main types of jets currently manufactured by Amoref. These are 1) The suction nozzle where the jet is up at the nozzle point, and 2) The power jet where the jet is located up near the sluice box. In addition to pumping water, the small engine can also produces compressed air for the diver to use while underwater. In cases where the water is shallow the gold diver may simply use a snorkel. Amoref suction dredges are made to float on the surface of the water, allowing the operator the greatest level of flexibility to move from place to place and work small deposits. Flotation systems are made of rigid plastic pontoons or hypalon inflatable pontoons to reduce transport size when needed. The CD-1 is competitively priced to get your gold dredging operations going and profitable in record time and increase your recovery rates.
