8 inch sand dredger is widely used to recover materials from great depths and can also extract sand from below a clay overburden which is also called jet sand suction dredger. 8 inch sand dredger is equipped with high pressure water pump and powerful sand suction pump. The water pump can produce high pressure high speed water jet to impact the bottom of sand layer and splashing the mixed sand around the suction head, and the sand suction pump conveys the sand to the destination through the discharge pipe.

Our Ghana customer wanted to order a 8 inch sand dredger to suck the fine sand from a small river. There were no big stones or gravels in the river. The dredging depth was around 5-10 meters, and they required 100 m ³ sand per hour, the discharge distance was 500-800 meters. According to these data, we chose a dredge machinery specification for customer. We recommended OCEAN PUMP 200 PNS -30 high efficiency wear resistant marine sand pump to be equipped into the river sand extraction dredger, the sand pump was driven by Yuchai 162 KW diesel engine. As the dredging depth was not very deep, we chose manual hoist instead of electric winch to lift the sand suction rubber hose in front of the river sand extraction dredger. The high pressure water pump and anchor winch were both driven by diesel engine. With this way, the whole river dredging system no need to use the generator set, it was not only retains the use of function, but also saved the customer’s costs.

In the process of communicating with customers, we understood that the customer had the ability to weld the dredge machinery body by himself. So we can only provide the main pontoon, he would weld the side pontoons by himself. In the main pontoon, we connected the sand dredging pump with diesel engine, water pump with diesel engine, and other accessories. At the same time, we provided the side pontoons drawings to customer, and then he welded the side pontoons in the local place. With this way, customer saved processing costs and transportation costs.
For sand discharge pipe and sand dredger floater, customer needed 8 inch HDPE pipes, it would need 3 pairs floaters every 10 meters pipes, 500 meters pipes needed 150 pairs floaters. As customer had some old oil drums around his worksite, so he used the oil drums instead of floaters.
Since we had already connected the main components of the river sand extraction dredger, the rest of the work was very simple. We tested the sand slurry pump dredger before shipment and took videos to show customer how to install and operator it. After the dredger arrived the worksite, the customer connected their welded side pontoons to our main pontoon perfectly.
