Defination

The bucket dredger is one of the mechanical dredgers. A bucket dredger is a stationary dredger that is equipped with a continuous chain of buckets, which are carried through a structure, the ladder

Area of application

Bucket dredgers are only used in new or maintenance dredging projects when the initial depth of the area to be dredged is too shallow for trailing suction hopper dredgers and the distances involved are too long for hydraulic transport. For environmental projects, which require the dredging of ‘in situ densities’, the bucket dredger is suitable peace of equipment. When dredging for construction materials such as sand and gravel, or for minerals such as gold and tin ores, bucket dredgers are still frequently used.

Advantages

Bucket dredgers can be used in almost every type of soil, from mud to soft rock. When rock has been fragmented by blasting, bucket dredgers are often used, because of their relative lack of sensitivity to variations in the size of the stones. It have good ability to fit different kinds of geologic structure. With the advantages of stable performance, long working life, low cost, high efficiency and little maintenance, It is suitable for sand digging from river and lake. This kind of dredger can also be used in salt mining, offshore dredging, hard riverbed exploiting and channel cleanning. The pure sand after being sieved and washed by the dredger is widely used in construction industry. It can be equipped with ore mining machinery for gold, diamond selection or iron separation. The machinery has the features of automatic work, good extraction rate and high capacity.
