Melted materials are pumped into the feed tube by high pressure pump, and achieve high pressure (adjustable), enters into the rotating chamber in tangentially. The materials liquid gains rotary force in the rotating chamber. In terms of the conservation law of spin angular momentum, rotating speed is in inverse proportion to the radius of the whirlpool; so the closer the liquid approaches to the axis, the greater the rotation speed will increase and the smaller the static pressure will be. Consequently, it forms a gust of air pressure in middle of the atomizer which is equivalent to the air cyclone of atmospheric pressure, and the liquid becomes the circular film revolved by the air core. Meanwhile, by means of hydrostatic pressure being converted into kinetic energy of liquid film, the liquid is sprayed out from the pressure nozzle in high speed. The liquid film stretches, attenuates and divided into small droplets finally.
The ambient air enters into air condenser, and heat exchanged to set temperature inside the condenser , then flows through the hot air distributor, and enters into the tower. The fine mist (the size of the mist can be adjusted) contacts with the cooling air and is solidified instantly, and cooled continuously in the process when it drops down. The cooled materials will be discharge from the congealing tower and the cyclone, and the air will be exhausted by the exhaust fan.
1.Material temperature: the material temperature influences the working capacity of the equipment. We normally consider the temperature between the melted material feeding temperature and melting point, or solidification temperature. The capacity is lower when the feeding temperature is higher. When the melted material temperature is too high (such as the temperature is more than 50 ° C higher than melting point or solidification temperature), it is suggest to cool the product before feeding, so to fully utilize the capacity of the equipment.
2.Property of the material. The solidification properties of different products are always different. The main properties that influences the congealing processes are melting point (or softening point), density, heat transfer factor, crystallization property, and viscosity (or surface tension) etc. The viscosity and surface tension mainly influence the quality of pellets, and others influence the cooling and solidifying speed, so to influence the capacity. Generally speaking, The higher melting point and density, the bigger heat transfer factor, the smaller latent heat, the bigger capacity, and vice versa.
