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.
