Product Details
Energy Saving 3-10T/H Small Three Cylinder Rotary Sand Caco3 Clay
Drum Dryer Machine
Brief Introduction of Three Cylinder Rotary Sand Dryers:
MG Three-cylinder Rotary Dryer is composed of three concentric
cylinders with different diameters. The special three-cylinder
structure makes the inner cylinder and the middle cylinder
surrounded by the outer cylinder to form an own thermal insulation
system. The heat emitted from the surface of the inner cylinder and
the middle cylinder is involved in the heat exchange of the
materials in the outer cylinder, and the outer cylinder is at the
low temperature end of the hot gas flow, so the heat dissipation
area and heat loss of the cylinder are significantly reduced.
Energy-saving three-cylinder dryer can make full use of waste heat,
reduce heat loss, increase the heat exchange area.

Application of Three Cylinder Rotary Sand Dryers:
MG dryer is mainly used for drying river sand, yellow sand, silica
sand, limestone, quartz sand, mechanism sand and various
specifications of sand, slag, coal ash, clay and so on.
Damp and sticky material: Coal slime, sewage sludge, bentonite,
Kaolin etc.
Corrosive material: Distillers ‘grains, Fertilizer, animal dung,
slag etc.
Biomass material: Sawdust, wood chips etc.
