Spray Dryer Series

The working process of the unit is that the feed liquid is fed through the diaphragm pump under high pressure to spray mist droplets, and then flows down in parallel with hot air. Most of the powder particles are collected by the discharge port at the bottom of the tower. The waste gas and its fine powder are separated by the cyclone separator. The waste gas is discharged by the exhaust fan. The powder is collected by the pollination cylinder located at the lower end of the cyclone separator.

YPG series pressure spray (cooling) dryer

Centrifugal spray dryers are divided into open type and closed type. They are mainly used in the drying production of battery materials, positive and negative electrode materials and sodium ion materials. They adopt high-speed centrifugal spray atomization technology (linear speed can reach 250 m/s) which is in line with the most advanced international technology. While realizing continuous drying production, they can obtain micro-spherical particles with uniform particle size, compact structure and good fluidity. To a large extent, high-speed centrifugal atomization technology, it can effectively improve or increase the packing density of the positive electrode material lithium iron phosphate, so that the monomer particles can reach 3 ~ 5μm and the moisture content of the finished product is 0.5%. The magnetic filtration technology is applied to effectively avoid the incorporation of iron ion impurities in the production process, so as to achieve the purpose of material purity and maintain the conductivity of the positive electrode material. The recycling of waste heat gas can achieve the production purpose of energy saving and emission reduction, and conform to the energy saving and emission reduction and low-carbon production mode advocated by the state.
