New Condition Chain sand dredging devices made up of bucket for Export

Description:

It is to fix mud(sand) dredging devices made up of bucket bridge,bucket chain and mud bucket on the center notching part of the bow or stern. When dredging,put the lower end of the bucket bridge into some depth of the water, making the mud(sand) bucket touch the soil(sand).

Driven by the guide pulley on the upper end of the bucket bridge, the bucket chain operates continuously. It can dredge the mud(sand) by the mud bucket on the bucket chain. The dredged mud and sand are transported to the top of the bucket tower. After changed direction by guide pulley, the mud and sand in the bucket are put into mud well from the mud bucket under gravity of themselves. The mud and sand are discharged out of the ship board by the chute.

Short Introduction

1 mining dredger consists of mining system , sifting system and separating system . Used for mining and separating heavy particles ,like alluvial gold, wolfram , Stannum , etc .

2 Requirement : The content of sticky clay , big gravels and stones should be less than 30% and the stone size should be smaller than 100mm .

3 According to requirement , can equip Nomal sluice , Pulsating , jigging sluice , STL Centrifugal Concentrator , etc . If the deposit contain magnetic sand , can also equip magnetic separator .

4 Dredging depth and capacity can be customized . Recovery rate higher than 90% .
