High-Quality Gold Gravity Knelson Centrifugal Concentrator Separator Manufacturers, Suppliers

Knelson gold centrifugal concentrator is a kind of efficient gold dressing apparatus, especially for recovery of fine gold. It is also called gold centrifuge,  featured by utilizing the principle of gravity acceleration. The key part of the machine is a cone shaped concentrate bowl, rotating at a high speed by an electric motor and a pressurized water jacket.

Product Description

Working principle

The machine utilizes the principles of centrifuge to enhance the gravitational force to separate minerals based on particles density. Once operated, the lighter material flows upward over the grooves and heavier mineral particles become trapped within them. With pressurized water injecting along the perimeter of each groove to maintain a fluidized state of particles, heavy mineral particles can be concentrated in an efficient way at last.

Frequently Asked Questions

Q: How does the machine separate minerals?
It utilizes the principles of a centrifuge to enhance the gravitational force, which effectively separates minerals based on the density of the particles.
Q: What is the role of pressurized water in this concentrator?
Pressurized water is injected along the perimeter of each groove to maintain a fluidized state of the particles. This allows heavy mineral particles to be concentrated efficiently.
Q: What are the capacity differences between the STL-30 and STL-100 models?
The STL-30 is a smaller model with a capacity of 3-5 t/h, whereas the heavy-duty STL-100 model can handle capacities ranging from 80-100 t/h.
Q: What is the power requirement for the different models?
Power requirements scale with capacity: the STL-30 requires 3 kw, the STL-60 requires 7.5 kw, the STL-80 requires 11 kw, and the STL-100 requires 18.5 kw.
Q: What is the recommended slurry density and feed size range?
All models operate within a slurry density range of 0-50%. The feed size range starts at 0-4 mm for the STL-30 model and goes up to 0-6 mm for the STL-80 and STL-100 models.
Q: What water pressure is required to operate the machine?
The required water pressure varies from 0.05 Mpa for the STL-30 model up to 0.2 Mpa for the STL-100 model.
