Operation method

♦ This set is an apparatus that can finish drying and granulating at the same time. The needed ball granule with certain size

 and ratio can be got in accordance with requirements of process to adjust pressure, flow, and size of atomizing hole.
♦ The working process of this set is as follows:the liquid of raw material is pumped in through diaphram pump. The liquid of

 raw material is atomized into tiny droplets. Then it falls down with hot air in co-current form. Most parts of powder material 

is collected through the discharge port at the bottom. The exhaust and fine powde「are separated by goingthrough the cyclone, 

and the exhaust is discharged by draft fan. The outlet of fan can also be equipped with two grades of duster. And its recovery 

ratio will be 96-98%.
♦ The tower body, pipes and separator of this set contacting with raw material are made of SUS304. There is enough layer of 

heat preservation between inner and outer case of tower body. The filled material is fine glass cotton. The tower body is also 

equipped with observation door, sight glass, lamp-house and control meters and instruments that are controlled and displayed 

through electric control panel.
♦ The heat source of this set may be steam or electric heater, with the features of convenient operation.quick start, compact 

structure clean hot air etc. Moreover, installed control and regulation device of the electric heater inside eletctric control cabinet,

 the inlet temperature can be controlled through stepless regulation. The steam, coal fuel or oil fuel can be applied to the place 

where has not electricity. It can replace electric heating partially or fully. The factory can provide different heating ways in accordance 

with the practical conditions of customer.

Features

♦ The drying speed is fast. The surface area of liquid raw material after being atomized will be increased greatly.95-98% of moisture 

can be vaporated at the moment. The time of drying needs about ten seconds to several tens of seconds. It is suitable for drying heat

 sensitive material particularly.
♦ The finished product is ball granule with uniform size. Its fluidity and solubility are good. The purity of product is high and its quality

 is good.
♦ Its scope of application is wide. According to the characteristics of raw material, it can use hot air to dry and can also use cool air to 

granulate. It has strong adaptability to raw materials.
♦ Its operation is simple and stable and its control is simple and convenient and is easy to realize automatic operation.

Scope of Application
