Construction Industry: drying gypsum, clay, bentonite, kaolin, limestone, sand, quartz and other materials in the construction industry.

Mineral Processing Industry: drying slag, tailings, copper ore powder, gold ore powder, iron ore powder and other mineral material in ore processing industry.

Working Principle

The material enters the cylinder from the feeding box and the feeding material is pushed backward by the spiral plate. As the dryer is placed obliquely, the material flows to the rear end under the action of gravity and rotation. On the other hand, the material lifting plate is repeatedly picked up, brought to the upper end and then continuously sown down, so that the material forms a uniform curtain in the cylinder, and fully exchanges heat with the hot air flow in the cylinder. The moisture is gradually dried and the purpose of drying is achieved.
