Sand dredger is the powerful sand dredging equipment which is widely used to recover materials from great depths and can also extract sand below a clay overburden in river, pond or lake. Sand dredger is equipped with high pressure water pump and powerful sand suction pump. The water pump in the sand dredger can produce high pressure and high speed water, the powerful water impact the bottom of sand layer and splashing the mixed sand around the suction head. Then the sand suction pump conveys the sand to the destination through the discharge pipe.
Brunei customer found us through google search, he added our international trade salesperson’s wechat. He inquired us about sand dredger machine in May, 2016. After asking about the actual working condition, we recommended him 8 inch small sand dredger and 14 inch jet suction dredger. He would use the dredge machines in the sea to suck fine sand, the work site was near the city. The sand suction depth was less than 8m.
We confirmed the detailed specification of the sand dredger with customer then waited for his government mining permission. In August, the customer told us that he got the government permission, and he wanted to use L/C (letter of credit) for payment. All transaction details were finished smoothly.
