The Novel Rotary Drying Machine

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

Because of its simple design, versatility, flexibility, large capacity and handling 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 dryer and the gas volume is usually large, medium and relatively high prices, energy. Specially designed rotary dryer, such as hole-shaped rotary dryer and heat - dry air flows through the rolling bed of particles, with good drying properties, but this type of dryer is the high capital investment and maintenance costs.
