1500 Mesh Calcium Carbonate Powder Coating Machine With Higher
Coated Efficiency
Four elements that influences calcium carbonate coating machine
working performance:
1. Powder fineness: modified powder in the coating machine must have a certain fineness, because powder fineness can reflect
its surface activity and functionality. The powder used in the
filler usually has a fineness of more than 325 mesh.
2. During the modification process in the coating machine, the appropriate and appropriate amount of modifiers should be
selected according to different additives on the surface of the
powder, different application directions or different requirements
of customers, and the choice of modifiers should be specific. In
addition, according to the variety, fineness and specific surface
area of the powder, a more appropriate amount of modifier should be
selected. If the dosage of the agent is too small, the powder
particles can not reach the maximum surface coating rate; if the
dosage of the agent is too large, the production cost will be
higher, and even the phenomenon of anti-coating will occur, and the
modification effect will be lower.
1.3 Dispersion and mixing of powder and modifier in the process of
powder modification, powder and modifier must be fully dispersed
and mixed, so that the modifier can maximize the coating or
activation of the mineral powder. If the powder cannot be fully
dispersed, agglomerated particles of the agent-coated powder will
appear, and the so-called "powder head" phenomenon will appear in
the product as a filler; if the modifier cannot be fully dispersed,
it will increase the dosage of the modified agent, which increases
the production cost; if the powder and the modifier are not
sufficiently dispersed and mixed, it will directly lead to a low
coating rate and activation index of the finished powder.
1.4 Modification temperature in the coating machine: the powder modification process is an endothermic process,
whether it is the physical coating of the agent on the surface of
the powder particle, or the chemical link between the active group
of the agent and the active functional group on the surface of the
powder particle, a certain amount of heat can be Promote the
efficient and rapid completion of powder surface modification.
Advantages of calcium carbonate coating machine:
Calcium carbonate powder coating machine can has the following
advantages: good dispersion of powder and modifier, better powder
modified rate, low labor intensity, higher productivity and
suitable for large-scale production. The ultrafine powder coating
machine is often installed with ultrafine powder mil for producing
coated ultrafine inorganic powder, especially for plastics,
polymer-based composite materials such as rubber, agglomerates,
painting, inks, organic fillers and pigments.
Working Principle of calcium carbonate coating machine:
There is a combination of shear, collision, air vortex and friction
in the ultrafine powder coating machine chamber, which can disperse
the powder and increase collision between powder and modifier. The
mixing time of 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 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.
