Spiral Concentrators — IMSC Group

Coal/Mica Spiral Spiral Concentrators Larger diameter units than the mineral-spiral series, these spirals are designed to take advantage of the particle shape differences. Take-off splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica.

STUDY OF THE SEPARATION FEATURES OF FINE COAL CLEANING IN ...

Kelsey Centrifugal Jig was found to be promising for the beneficiation of fine coal particles. The present study was aimed at in-depth understanding of the separation features of Kelsey Jig through detailed experimentation. Beneficiation of fine coal of size 150 x 300 μm was studied in a laboratory Kelsey Jig.

Effect of Operating Parameters on the Performance of Spiral ...

The raw sand used in experimentation contains 12.5% slimes and 11% heavy mineral concentrate, out of which 80% was in the particle size range of —250 + 106 pm. It has been observed that with increase in feed flow rate the grade of concentrate increased but as expected the recoveries decreased significantly.

Selection rules for screening operations of mineral ...

According to experts of mineral processing equipment, screening operations can be divided into the following categories: (1) Preparing for screening When screening is to provide candidate minerals of different sizes for the sorting operation, it is called preparatory screening. Such as mineral screening before gravity separation and magnetic separation. For the coal industry, all kinds […]

Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium (Wills, 2007) (Holland Batt, 1995b). Developments over the years include; improved feed box and splitter designs, trough design, wash water addition, capacity improvements, re-pulpers and product boxes (Holland Batt, 1995b).
