TRODAT Parts & Services has been designing and building dredging equipment for more than a century. It was the first to convert the dredging wheel into a highly efficient tool for dredging a wide range of materials. 

Thoroughly tested 

Excellent cutting properties, a constant dredging output in both directions of swing, and the almost complete 

absence of blockage ensure high production. Optimum mixture density, low spillage and low sensitivity to debris such as rocks and tree stumps significantly contribute to efficiency. The dredging wheel may be seen as the most thoroughly tested and developed tool of its type, and the best for meeting the growing demands of the dredging and alluvial mining industries. It is capable of achieving a mixture concentration of 70 per cent

Features 

• upward and downward cutting models available 

• accurate selective dredging at flat bottom profile 

• constant feed rate to mining treatment plants 

• built-in root cutter. 

Benefits 

• larger debris cannot enter the wheel 

• reduced risk of large clay ball formation 

• high mixture density 

• high production and low spillage 

• equal production in both directions of swing 

Cutting edges and replaceable teeth 

Bucket wheel dredgers of various inches  can be used for different soil types, from peat and clay to sand and soft rock. The buckets can be fitted with either smooth cutting edges or replaceable teeth of the pick point, chisel point or flared point variety.These replaceable teeth are the same as those used on cutter heads. Standard dredging wheels are available in a power range from 20 to 1,000kW and outputs of up to 10,000 tonnes/h. 

Minimal blockages 

Bucket wheel dredgers of various inches  essentially consists of a hub and a ring connected by bottomless buckets which excavate the soil. The scraper of the suction mouth penetrates into the bottomless buckets, and guides the mixture flow towards the suction opening, which is in direct contact with the 

buckets. The scraper completely prevents clogging of the buckets. 

As the buckets, suction mouth and scraper are oriented in the same plane, the mixture flow is very smooth. 

Designed for purpose 

Depending on the power required, the drive mechanism can consist of one single hydraulic motor mounted in a steel housing or can be a gearbox with several hydraulic drives. For special purposes electric drives .For special purposes electric drives may also be used. The gearboxes used on the dredging wheels are designed specifically for the purpose since they are required to transfer all loads from the wheel (with bearings on one side only) to the ladder. The gearbox and the bearings are designed for optimal lifetime.The special sealing arrangement protects the power train from wear and damage caused by the ingress of soil.Dredging wheels are supplied as complete units, including drive and ladder adapter. They can be used on standard and customised wheel dredgers, or as replacements for cutter or wheel installations on existing dredgers.

Note

Calculated output curves only indicate pumping capacity, based on the maximum .available power on the pump shaft and free-flowing material. In actual practice, properties may vary from free-flowing, easily excavated to compacted,hard-to-excavate material. When used for estimation actual outputs, the nature of the material to be dredged and local job conditions must be considered.Please consult TRODAT for dredging conditions outside these curves.

Need For Reply

We will design and integrate reasonable schemes according to the needs of different customers and combined with on-site working conditions to achieve the most cost-effective equipment configuration to the greatest extent. So there are some questions needed to be mentioned as follows: 

a. How many tons per hour for the dredging capacity ? 

b. How many meters for the dredging depth? 

c. What is the percentage/ratio of sand of sand and stone ? 

d. What is the granularity of gold (gold particle size) ?

e. Do you need a generator set? If yes, which brand? 

Of course, We have been in the dredging business for More than 15 years , established itself not only as an efficient production facility, but also as a dedicated dredging knowledge center which our customers can rely on.
