Modifying Marble Limestone Turbo Mill Surface Coating System With CE ISO Certification

 Modifying Marble Limestone Surface Coating Machine

With CE, ISO Certification 

Our continuous powder surface coating systems are designed on the base of German know how, and can be used for coating of various powders like calcium carbonate (GCC, PCC), kaolin, talc, mica, graphite, barium sulfate, white carbon black, carbon black, magnesium hydrate, zinc oxide, aluminum oxide, and is suitable for a variety of solid/liquid coating agents, like aluminate coupling agent, titanate coupling agent, silane coupling agent and stearic acid.

We have developed 3 different continuous surface treatment systems/ coating systems on the base of successful experience of Hosokawa Alpine and Omya Group, pin mill coating machine, turbo mill coating machine, rotor mill coating machine.

High-speed rotation creates great vortex flow inside these special-shaped rooms. Powder and coating agent are mixed in the high-speed gas-solid vortex flows. Coating machine with both surface coating and particle dispersing functions is suitable for various powders with different fineness, and has a unique coating effect for the materials with small apparent specific gravity and high volume to weight ratio.

Automatic temperature control system ensures stable high temperature for coating agent melting into liquid and mixing with uncoated powder. Heating and cooling of powder and coating agent are completed in one machine, which does not need independent cooling system.

High utilization ratio of coating agent, high powder-coated rate, high activation grade, low energy consumption, and very few agglomerates in final coated product. The whole system is operated under negative pressure, no dust emission, and low labor intensity.

Surface-treated limestone powder - generally called “coated limestone powder” - is used as a filler in

the production of PVC as well as other plastics. Limestone or ground calcium carbonate (GCC) with a

fineness of d97: 45micron to 5micron as well as precipitated calcium carbonate (PCC) of d50 < 0.1

micron are mainly used.

The most important target with this process is a uniform and complete distribution of the coating agent

in the limestone powder. The proportion of coating agent is only 0.4- 1.4% by weight for GCC and up to

5% weight for PCC. And in order to uniformly supply this small quantity to the large amount of limestone,

the coating agent is melted and then mixed with the limestone powder. Natural or synthethic max (eg.

Stearic acid) is predominantly used as a coating agent.

We have developed 3 different continuous surface treatment systems/ coating systems on the base

of successful experience of Hosokawa Alpine and Omya Group, pin mill coating machine, turbo mill

coating machine, rotor mill coating machine.
