3-5 Ton Per Hour Calcium Carbonate Coating Machine with 98% Coating
Rate
Calcium carbonate coating machine is to modify and dry the surface
of calcium carbonate powder to improve the physical and chemical
properties of its surface, enhance its compatibility with the
matrix, that is, organic polymer or resin, etc. dispersibility to
improve the mechanical strength and comprehensive properties of the
calcium carbonate powder.
Features of calcium carbonate coating machine:
Calcium carbonate coating machine adopts continuous production
design, and the coating rate can be as high as 99% or more. It is
an ideal equipment for calcium carbonate surface modification.
Calcium carbonate coating machine working process:
The preheated and dehydrated calcium carbonate fine powder is
quickly heated to 100-120 ℃ in the coating machine chamber after
quantitative feeding. The modifier heated to the set temperature is
conveyed into the modification chamber by high-pressure air through
a special nozzle. Fully contact with calcium carbonate powder
particles, and then calcium carbonate powder collides with each
other in the modification chamber, so that each particle is fully
coated. Due to the phenomenon of agglomeration between the
particles during the coating process, the coated particles are
impacted by the modification hammer when passing through the
outlet, so that the agglomerated particles are fully dispersed. The
modified micro powder enters the cyclone, so that the modifier
quickly becomes a solid state as the temperature decreases,
preventing the particles from sticking together again and affecting
the modification effect.
Working principle of calcium carbonate coating machine:
The calcium carbonate coating machine completes the powder surface
treatment mainly by means of three modified cylinders, the dried
powder and the accurately metered modifier, which enter the
modification cylinder at the same time, and form a fluidized screw
with the high-speed rotation of the rotor. It is rapidly modified
to form a film by the heat generated by the high-speed running
powder collision, friction, shearing and high-speed rotating rotor.
