How do spiral concentrators work?
Slurry is pumped to the upper part of the spiral, which is usually 33 to 38 cm from the floor. From there, it enters a feed distributor, which evenly distributes the feed to each spiral concentrator. Gravity, along with the specific design and shape of the spiral, are the key to making it work.
