New Delivery for Iron Ore Cone Crusher For Secondary Crushing - Gold Gravity Knelson Centrifugal Concentrator Separator – Ascend

Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines utilizes the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density.The key components of the unit are a cone shaped “concentrate” bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl.Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above.The feed slurry contacts the base plate of the vessel and due to its rotation, is thrust outward. The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove.

Working Principle

In operation, material is fed as a slurry of minerals and water into a rotating bowl that includes special fluidized grooves or riffles to capture the heavies. Fluidized water/back wash water/recoil water is introduced through the multiple fluidization holes in the inner cone to keep the bed with heavy minerals. Fluidized water/back wash water/recoil water plays an important role during the separation.

Specification

Product Advantages

1)High recovery rate: Through our test, the recovery rate for placer gold can be 80% or more, for rock rein gold, the recovery rate could reach 70% when the feeding size is below 0.074mm.

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)
