5, the effect of distributing device 9 is that liquid material or adhesive are added in solid material.Facts have proved, if adhesive is directly injected to solid material, adhesive can be combined with solid material rapidly and be formed the larger bulky grain of water capacity under capillary effect, has a strong impact on and granulates and drying effect.If by the mode of the atomization adhesive of annotating, have the problem of two aspects: the one, high viscosity liquid material (as more than 1.25 Chinese medical concrete of proportion) is difficult to atomization, the 2nd, both allowed to atomization, the lower adhesive of spray also can be at solid material surface shape face liquid film, and then contraction is formed into bulky grain rapidly.The distributing device 9 that the utility model is designed, adhesive is passed through to High Rotation Speed, from cloth tray slit with film-form or vaporific throwing away, and distributing device 9 slits are embedded in material, like this, the material throwing away has little time to shrink and agglomeratingly can mix with solid material around rapidly, forms the very solidliquid mixture of homogeneous, has greatly improved mixed effect.

6, the three-decker of sieve plate 10 design, has gathered the rigidity of orifice plate and the small-bore advantage of screen cloth.As independent use screen cloth, himself is softer, is difficult to keep integral rigidity and flatness, easily causes damage simultaneously when scraper; Use separately orifice plate, cannot make less aperture again.Both combinations, have guaranteed flatness and ventilation effect, can not leak powder to turning barrel 5 cavity of resorptions simultaneously.

7, utilize said structure, the common rotation of turning barrel 5, doctor assemblies 20, rotor assembly, distributing device 9, makes material tumble mixed in turning barrel 5 working chambers.Thereby traditional fluidized drying is the hot blast by Wind Volume, make material realize and mixing and functions/drying in a kind of suspend fluidized state, therefore have the problem that hot blast air quantity is large, energy consumption is large, dust is large, equipment volume is large.The utility model equipment is in dry run, and breeze fan 23 hot blast that send passes through gap between particle packing thing and upwards flows, and material does not need suspend fluidized, the state in a kind of " micro-boiling " on surface only, thereby air quantity is little, energy consumption is low, dust is little.In addition, do not need the auxiliary process media such as Boiler Steam, compressed air; Meanwhile, turning barrel 5 structures of rotation, make vacuum discharging become possibility.
