Product introduction
This unit is a device that can complete drying and granulation at the same time. The pressure, flow and orifice size of the feed pump can be adjusted according to the process requirements,
get the required spherical particles in a certain proportion of size.
Working principle
The working process of the unit is that the feed liquid is injected through the high pressure of the diaphragm pump to spray out the atomized liquid droplets, and then flows down in parallel with the hot air. Most of the powder particles are collected by the discharge port at the bottom of the tower. The waste gas and its tiny powder are separated by the cyclone separator. The exhaust gas is discharged by the exhaust fan. The powder is collected by the pollinator at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of more than 96-98%.
Performance characteristics
◎ The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% - 98% of the water can be evaporated instantly. The drying time is only ten to ten seconds, especially suitable for the drying of heat-sensitive materials.
◎ All products are spherical particles with uniform particle size, good fluidity, good solubility, high purity and good quality.
◎ It can be used in a wide range. According to the characteristics of materials, it can be dried with hot air or granulated with cold air, which has strong adaptability to materials.
◎ Simple and stable operation, convenient control, and easy to realize automatic operation.
