Vortex mill coating machine is composed of frame, body, stator, rotor, filling hopper, bearing seat and motor. The vortex mill coating machine has the features of high rotational speed, long service life, convenient maintenance and high crushing efficiency.

Heavy calcium carbonate is a kind of energy-saving, green and environmental protection mineral material. Due to its special physical and chemical properties, as well as its low price and wide sources, it has become one of the main modified powders of vortex mill coating machine.

Common modified materials: The vortex mill powder coating machine has good surface modification effect on heavy calcium carbonate, light calcium carbonate, kaolin, talc, wollastonite, quartz powder, mica, titanium dioxide, zinc oxide, alumina, magnesium hydroxide, barium sulfate, illite, chlorite, tremolite and other ultrafine powders.

Wide applications: The finished coated powder from the vortex mill coating production line is widely used in the paper, plastic, rubber, paint and coating, adhesive and sealant and building materials industries.

application of vortex mill coating machine

Why do you use the vortex mill coating machine?

  • Vortex mill coating machine adopts the principle of high speed vortex mixer impact stirring, which can atomize the modifier and coat the surface of the ultra-fine powder. This will reduce the amount of modifier and achieve the purpose of powder modification.
  • The powder surface coating machine is equipped with ultra-fine classifier system to guarantee the modification rate of 99% and stable product quality.
  • For the same coating rate, the vortex mill coating machine uses less stearic acid consumption than the three-roller coating machine.
  • This machine is easy to install and maintain, and can be cleaned by opening the top cover.
  • The whole process is fully sealed, and there is no risk of leakage and pollution from dust transport.
  • The material of the core rotor of the vortex mill powder modification machine adopts German technology, and the line speed can reach 115m/s, which has the characteristics of high quality and high wear-resistance.
  • The vortex mill coating machine is capable of continuous operation, resulting in stable production.

Working principle of vortex mill powder coating machine

The mineral powder is fed from the top of the modifier, pre-crushed by the upper cover of the rotor and then thrown into the main machine. The material enters the comminution zone between the stator and the rotor. The conical crushing area creates ventilation conditions between the rotor and stator.

Under the combined effect of centrifugal force and suction, the right amount of material impacts the edge of the blade at high speed and there is a fierce collision between the material and the material. Through this repeated impact, collision, the material can achieve the purpose of ultrafine grinding.

Features of coated calcium carbonate powder

Coated calcium carbonate, also known as active calcium carbonate, is the main finished product of the vortex mill coating machine. So what are the characteristics of the coated calcium carbonate powder?

The appearance of coated calcium carbonate is white powder, which is non-toxic, tasteless, non-irritating, non-flammable, non-explosive, low refractive index, easy to color, insoluble in water, and stable in the air.

wide usage of coated calcium carbonate

The modified calcium carbonate has better lubricity, fluidity and organic properties than before modification. Modified calcium carbonate has the features of good gloss, uniform dispersion, and large filling capacity.

Coated calcium carbonate powder has strong intermolecular affinity with rubber and plastic, and the filling amount is 2-5 times that of ordinary calcium carbonate.

Coated calcium carbonate has superb metal stripping and remarkable lubricating effect, and also improves the surface brightness, anti-wear and anti-impact strength of products.
