Graphene rotary furnace is mainly composed of rotary furnace body, lifting plate, transmission device and electrical control part.

The rotary furnace is made of high-quality resistance wire, the cylinder is heated up and down, the furnace body is a rectangular furnace shell, which is composed of refractory materials and heating elements, the furnace tank is made of stainless steel 310S material, the furnace tank is supported on several pairs of supporting wheels, and has an inclination of 3% - 6%. The furnace tank is driven to rotate slowly by the reducer through gears. On the one hand, the material flows to the back end under the action of gravity and rotation; on the other hand, the material is repeatedly picked up by the plate, carried to the upper end, and then continuously spread, so that the material forms a uniform curtain in the cylinder, and fully exchanges heat with the hot air flow on the inner wall of the cylinder. As the material is repeatedly spread, the moisture content is gradually dried, so as to achieve the purpose of drying. The rotary furnace is equipped with interlock protection device, which can prevent faults and accidents caused by misoperation; it has high mechanization, high production efficiency, no pollution and good environmental protection benefits.
