Coating Machine with Higher Coated Rate for Calcium Carbonate
Powder
In different industries, ultrafine calcium carbonate powder is
always used as raw material to improve the final product property
and save production cost. In order to make full use of the
ultrafine calcium carbonate powder with higher powder surface area,
coating machine is always used to prevent the calcium carbonate powder from being
agglomerated. To solve reunion and improve dispersion and fluidity
properties, it is very efficient to use powder modification method.
In this way, it can increase the repulsion between powder
particles, reduce the gravity between the powder particles, make it
easy to disperse, and improve the application performance of the
calcium carbonate powder.
Components of Calcium Carbonate Coating Machine
This equipment consists of 1. powder feeding device 2. modifier
metering device 3. Spraying device 4. coating chamber 5. pneumatic
system 6. pulse-jet collector 7. electric control cabinet
Coating machine can bring the following advantages for calcium carbonate powder:
good dispersion of calcium carbonate powder and modifier, better
modified rate, low labor intensity, higher productivity and
suitable for large-scale production. The coating machine is often
installed with ultrafine calcium carbonate powder mill for
producing coated ultrafine calcium carbonate powder, especially for
plastics, polymer-based composite materials such as rubber,
agglomerates, painting, inks, organic fillers and pigments.
The working principle of the coating machine for calcium carbonate
powder:
There is a combination of shear, collision, air vortex and friction
in the coating machine chamber, which can disperse the calcium carbonate powder and
increase collision between calcium carbonate powder and modifier.
The mixing time of calcium carbonate powder and modifier can be
increased by the air vortex. And the temperature can be kept at a
suitable degree with the help of collision between calcium
carbonate powder and modifier. Advanced artificial intelligence
technology is used to adjust all process parameters and
modifier&powder feeding-rate. This can help to achieve the
absorption of modifier to powder surface and stabilize the modified
powder quality.
Special features of ultrafine powder coating machine:
No-stop feeding and powder modification; better dispersing
function; higher modification rate, same force for powder and
modification; modification time and temperature can be adjusted;
lower power consumption; automatic control for easy operation; no
powder pollution and environment-friendly; higher output,
325-6000mesh modification.
