small river sand pump dredger

Many alluvial gold is under river, so a good mining dredge is very important for river gold mining. After decades experince, we designed and produce 3 type dredge for alluvial gold mining. They are Pump Dredge, Chain Bucket Dredger, and Cutter Suction Dredger.

1. Pump Dredge.

Although the bucekt dredger is the best choice for alluvial gold mining. But it's too big and expensive for new investor. For new player, smaller dredge is best choice. It can help miner use the lowest investment to get the highest repay.

There is many pump dredge, but the principle is same. It all use a Submerged Slurry Pump. The follow is principle picture.

Submerged Pump

The pump is the key parts for pump dredger. For some small dredge, is only a pump and float. So how to choose the pump is the most important thing. We use Stir-Impeller Submerged Slurry Pump.

This pump has a stir-impeller at the bottom. The impeller can stir sand, forming slurry. This design can improve the effects amazingly.

We have  multiplicate pump for clients to choice. 

 When the pump is selected, we produce dredge based on clients' requirment. For example, the following is a simple small dredge.

This dredge has a windlass, which can control the pump up and down. The pump and windlass is controled by a panel box. Simple design, low investment, but not low effect.

When clients has bigger plan, we also produce dredge accordingly.

This is a bigger dredege. It has two extra big stir-impeller. The suction is much better and the capacity is much bigger.

Except professional pump, operating room and boat body, it also has screw propeller on the back. It's self-propelled.
