Washing and淘Gold Mining Equipment

The application of washing and淘gold equipment in gold selection in New Zealand: The washing mine cylinder screen further enhances the fragmentation and sieving process, reinforcing both mechanical and hydraulic actions, extending the material's residence time within the sieve, and increasing the effective sieving area by over 25%. Further research is required on the sieve's annular retaining ring, spiral crushing teeth, and longitudinal lifting plate, etc., tailored to the nature of the ore sand to enhance the fragmentation effect. When used in conjunction with chutes and centrifuges, it achieves a better gold selection outcome.

Centrifugation utilizes the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation rate of particles in the liquid, separating materials with different sedimentation coefficients and buoyancy densities. Therefore, it is necessary to use the centrifuge to produce a strong centrifugal force to force these particles to overcome diffusion and initiate sedimentation. It is suitable for the recovery of free gold from sand gold, lode gold ore, and polymetallic ore, replacing mercury board operations. It can also be used for the concentration of gold-rich sands obtained from gravity concentration tables and gold recovery ships.
