After the potash has been pelletized, the "green" pellets must be brought down to the moisture level required for the end product. It is here that an industrial drying system must be employed. A dryer such as a rotary dryer, specifically designed around material and process requirements, will achieve the best results.
Hot air blown from a fan speeds the vaporization of moisture within the wet sand. Dryers receive the hot air as it's blown into their interior to remove the moisture. The fan adjusts airflow, transporting materials within and from the sand dryer. The moving air also dissipates any waste gases from the drying process.
Posted on December 7th, 2023 by hpprocess. Rotary dryers are used to remove moisture from bulk materials through heating. This is done either directly or indirectly with heated air and/or gasses. They can consist of several drums (also called shells) or a single drum, with multi-drum rotary dryers enabling equipment to produce greater throughput in the same size space.

Historical Origins Of Potash Production. The first industrial chemical patented in the United States in 1790 was potash.Potash is a compound made of potassium, which is an essential element for the human diet.Its name actually derives from the Dutch word "potaschen," meaning pot ashes, as it was initially extracted from the ash of native hardwood trees.
Rotary dryers are the most common dryer type used, although fluid bed dryers are also used. Typical rotary feldspar dryers are fired with No. 2 oil or natural gas, operate at about 230E C (450E F), and have a retention time of 10 to 15 minutes. Magnetic separation is used as a backup process to remove any iron minerals present. Following
