Pressure Pressure atomizer spray drying can be done at the same time a granulator and granulating drying apparatus, the material can be adjusted according to process requirements of the pressure pump, the size of the flow orifice of the desired size by a certain proportion of spherical particles. It uses pressure diaphragm pump with the help of the atomized solution or slurry material into small droplets, and then fall with a hot air flow, most particles collected from the bottom discharge opening, gas and tiny powder through cyclone separation, the significant increase in surface area, by heat exchange with the hot air sufficiently to rapid drying (over 10 seconds to tens of seconds), or fine particles obtained product equipment. Its source device using steam heating or electric heaters, with easy operation, start fast, compact, hot air are clean and so on. Also in the electrical control cabinet is equipped with an electric heater control adjustment means, the inlet temperature is not adjustable. For lack of electricity can be steam heating or coal, fue stove, etc., partially or completely replace the electric heating devices.
