The dry (cooling) of the wedge shaped hollow blade is an indirect heating/cooling machine, conducting is the main heat transfer way. The wedge shaped hollow blade and a hollow shaft have a special structure.  In the process of drying / cooling of the filter cake, powder, granular material,  the wedge blade rotate correspondingly, materials in the wedge-shaped blade shaft produce extrusion and relaxation effect, the blade of self-cleaning function makes containing The wet material is continuously updated, and the heat transfer to the material directly through the blade surface and the jacket.
Characteristic:
1、Compact structure, large heat transfer area, can be as much as 200m²;
2、The wedge shaped blade has a unique self cleaning function, and the heat transfer efficiency is higher;
3、To change the hollow blade shaft according to the operating parameters of drying materials require;
4、Heat transfer medium can be steam, heat conduction oil or cooling water, dehydration capacity 10~30t/hr;
5、Intermittent operation can also be continuous operation can be used in normal temperature operation can also

      be micro negative pressure
Applicable: Cool alkali, nano scale calcium carbonate, barium sulfate, flocculant, silica, zirconia, titanium dioxide, dye intermediates, calcium phosphate, Medical intermediates, medical vitamins, catalysts, carbide slag, sludge drying and other products of the dry / cooling operation
