Automatic Discharge Gold Gravity Centrifugation/Knelson Gold Recovery Concentrators

Detail Presentation

Knelson Centrifugal Gold Concentrator is a new type of gravity concentration equipment for gold separating and other high density minerals. The centrifugal machine has many competitive advantages compared with other concentration machines which create high returns for the investors.We have fully-continuous (Knelson Continuous Variable- Discharge, CVD type) and semi-continuous(Batch type) centrifugal gold concentrators.

Since 1985, three models of centrifugal concentrator have been developed. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of0.074mm, the recovery for the natural gold is expected up to 98%. For that natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.

Main Features

1) High recovery rate: Through our test, the recovery rate for placer gold can be 98% or more, for rock gold, the recovery rate could reach 97% when the feeding size is below 7mm.
2) Easy to install: Only a small leveled place required. It's a full line machine, before starting it, we only need to connect the water pump and power.
3) Easy to adjust: There are only 2 factors that will affect the recovery result, they are water pressure and feeding size. By giving proper water pressure and feeding size, you could get the best recovery effect.
4) No pollution: This machine only consumes water and electric power, and exhaust tailing and water. Low noise, no chemical agent involved.
5) Easy to operate: After finishing the water pressure and feeding size adjust, clients only need to recover the concentrates every 2-4 hours. (Depending on the grade of the mine)
