Product introduction

Gold dredger, also known as gold dredger, is a water combined plant integrating mining and beneficiation operations. It is a placer gold mining equipment. It includes excavation system, beneficiation and water supply system, waste ore and tailings disposal system, deck machinery, hull, power support, power and other basic systems.

Classification of gold dredgers

In terms of beneficiation process, gold dredgers are divided into fixed chute, belt chute, drum chute, self unloading fixed chute, water jacket centrifuge and circular jig. In terms of mining capacity, gold dredgers are divided into 15 l, 25 L, 40 L, 50 L, 100 L, 150 l, 200 L, 250 L and 300 L.
