Like most natural products, Potash in its raw form needs to be processed for it’s end use. To improve product handling, reduce dust, and create a consistent product size potash is compacted from a fine particle into a more easily handled granular form.

Compaction works on the principle that when put under extreme pressure potash will adhere to itself.

Feed particle size distribution is critical to the success of a compaction granulation circuit. Varied particle size distribution is ideal for the compaction process. When potash is pressed together air is removed and smaller particles will fill in the voids between larger ones. If the particle size distribution is too coarse the material will not move through the compactor well. If the particle size distribution is too fine the material will cause deaeration problems.

Potash compaction requires a feeding mechanism designed to create the desired product characteristics. A consistent pressure across the entire roll face width is needed to produce a granulated product.

March has extensive experience in potash mining and processing which includes all engineering aspects of Granular Potash Compactors. Do you have engineering questions that we can piece together and get the project moving?
