High Speed Centrifugal Spray Dryer
Electric Heating Graphene Carbon Powder Centrifugal Spray Dryer
Introduction
Description
The spray drying is the widest used technology in the liquid
shaping technology and in the drying industry. It is most suitable
for producing powder, particle, or block solid products from
materials of solution, emulsion, soliquoid and pumpable paste
states. Therefore, when the particle size and distribution of the
final products, their residual water contents, the stocking density
and the particle shape meet the precision standards, the spray
drying is one of the most desired technologies.

Feature
1, High speed of drying. After the spraying of he material liquid,
the surface area of the material will be increased greatly. In the
hot-air flow, 95%-98% of water can be evaporated at a moment. The
time of completing the drying needs only several seconds.
2, It is especially suitable for drying the heat sensitive
materials. It’s final products own the good uniformity, mobility,
dissolving capacity. And the final products are high in purity and
good in quality.
3, The production procedure is simple and the operational control
is easy. The liquid with the moisture contents 40-60%(for special
materials, the contents may reach 90%) can be dried into power or
particle products once a time. After the drying, there is no need
for smashing of sorting, so as to reduce the operation procedures
in the production and enchance the purity. The product particle
diamenters, looseness and water contents can be adjusted through
changing the operation condition in a certain scope. It is very
convenient to carry out the control and management.
Application
