Brief Introduction
The major structure of the machine follows about Knudsen Bowl from Australian mining company. The machine is primarily applied for washing and separating placer gold at a size of minus 4mm and is capable of recovering natural gold grains at sizes of over 15 um. In operation, inner hole of the center is blocked using plug with its drainage and collection at a regular basis. It can be operated intermittently or continuously, with the ore feeding and water adding simultaneously. The rotation direction is anti-clock at a speed of 70-110 r/pm. Ratio between solid and liquid for slurry is 1/4-2/3. The machine can be operated by power individually and multi-machines also can be operational in a combined.
The washing bowl is made of glass fiber, which is better coefficient of friction in water can get better gold deposition. The capacity is 0.5-1.5t/h per set, the rotation speed is 70-110rpm, high recovery ratio, simple structure, long used wear-resistant, can be continuous or discontinuous operation, single or multi machines assembly.
