Knelson Centrifuge for Lead Mining

We offer the full range of mineral processing solutions, and permanent technical support.

    The Knelson centrifugal concentrator utilizes the principles of centrifuge to enhance the gravitational force experienced by feed particles, which aids in the separation process based on particle density. The key components of the unit include: a cone shaped "concentrate" bowl, which is rotated at high speed by an electric motor and a pressurized water jacket encompasses the bowl. Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the center 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 concentrated bowl house a series of ribs, and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and the heavy mineral particles (usually of economic value) becomes trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. The Knelson centrifugal concentrator typically operates as a batch process, with lighter gangue material being continuously discharged via overflow and a heavy mineral concentrate periodically removed by flushing the bowl with water.

Centrifugal concentrator products advantages :
  1. High concentration ratio, which can reach 1000-3000 times, small concentrate productivity, generally 0.02%-0.1%, high concentrate grade, normally, 1000-20000g/t. Compared with conventional gravity dressing machine, the recovery is improved significantly.
  2. Large amount of solid mineral can be processed by single centrifugal.
  3. Without pollution or chemical agent, friendly equipment for environment.
  4. High activity rate, low power consumption ,high automation, low cost. The equipment has high running rate and low power consumption, which is easy to operate. High automatic level and easy to maintenance will cut the production cost.
  5. Short work flow procession means small investment will bring great value soon.
