In 1976, Benjamin Virgil (Byron) Knelson changed the face of the gravity concentration industry to what mining professionals know it as today. This was the year the the first Knelson Concentrator was tested and Knelson Concentrators, now owned by FL, has pioneered and led gravity concentration technology ever since.
The gravity concentrator uses minimum energy to separate minerals based on differences in gravity. It means the gravity concentration system's downstream processing will be more accurate and efficient.
