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.
