Description
Limestone Powder With Stearic Acid Surface Coating Machine
We have developped 3 types of different coating machines for fine powder surface treatment to make functional mineral and chemical materials.
- Pin mill coating system.
- Rotor mill coating system.
- Turbo mill coating system.
Coating Effect
Rotor Mill Coating
Our Rotor-Mill Coating Machine consists of three units of mixing rooms. 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.
Pin Mill Coating
Pin Mill Coating System:
The uncoated powder feeds into the system via dosing screw and heated by heating screw. The coating agent is fed into the melting tank and after melted into liquid which will be pumped into the pin mill. The heated powder and coating agent is pre-mixed in the bin by high-pressure air flow and then go into the pin mill. The powder is coated under the high-speed rotation of double pin discs. The coated powder is collected by bag filter.
Calcium Carbonate Coating:
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% to 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 like Stearic acid is predominantly used as a coating agent.
