To Support the basic shortcoming of traditional rotary drying machine, the development of a novel rotary drying machine. Its characteristics are: out from the branch of the air jet is particle strong movement to ensure full contact of gas and particles, and provides good heat and mass transfer conditions. Thus, compared with the conventional rotary drying machine, drying rate was almost double the wear particles are greatly reduced. Not only lead to higher drying rate of the smaller shell size and ancillary equipment more compact. Rotary drying machine is dealing with particulate materials, one of the most commonly used drying machine.



Because of its simple design, versatility, flexibility, large capacity and handle multiple types of raw materials (crushed minerals from the multi-cutting plant) capacity. Drying gas and for rolling the bed transfer process contribution to the team of only 5% of the wet solid materials, the convection heat and mass transfer between the main areas being made on the Raising of the particles in a "floating down" period. In addition, the material is relatively small capacity, 10% - 20%. Therefore, the traditional axial flow rotary drying machine and the gas volume are usually large, medium and relatively high prices, energy. Specially designed rotary drying machine, such as hole-shaped rotary drying machine and heat - dry air flows through the rolling bed of particles, with good drying properties, but this type of drying machine is the high capital investment and maintenance costs.
