Mastering Non-Metallic Mineral Processing: The Game-Changing Applications of Powder Surface Coating Machine

The surface treatment technology of powder modifiers includes surface modification methods, processes, surface modifiers and their formulas, surface modification equipment, etc. Among them, when the surface modification process and modifier formula are determined, the quality of the surface modifier becomes the key to powder surface modification or surface treatment. Let’s learn about the application of modifiers in non-metallic processing!

Mixing function: to achieve full mixing of powder materials;

Dispersion function: to promote uniform distribution of powder particles to avoid agglomeration;

Surface modification function: to make the surface modifier fully dissolved in the equipment and evenly dispersed on the surface of the material to form a firm bond.

Key process characteristics

Efficient dispersion: excellent dispersion ability for powders and surface modifiers to ensure uniform dispersion of materials;

Uniform action: to ensure full contact between powders and surface modifiers, and equal opportunities for action;

Flexible temperature control: the processing temperature can be accurately adjusted according to process requirements;

Energy saving and consumption reduction: low energy consumption per unit product, reducing production costs;

Green and environmental protection: effective dust prevention measures are adopted, and there is no dust pollution during the operation process;

Convenient operation: the equipment is simple to operate, stable and reliable in operation, and easy to maintain.

Structure and performance characteristics of Powder Surface Coating Machine

Structural composition

Powder Surface Coating Machine is mainly composed of thermometer, discharge port, air inlet, pipeline, main body, supply port, metering pump and supply machine, etc. Its system configuration generally includes supply device, modifier metering and adding device, main body, cyclone dust collector, bag dust collector, etc.

Working principle

The feeder supplies the modified material, which then contacts the automatically metered and continuously fed surface modifier. The mixture passes through three cylindrical modification chambers in sequence. Inside these chambers, the high – speed rotating rotor, stator, and powder material create impact, shearing, and friction, generating the heat needed for surface modification. The temperature, adjustable by rotor speed, powder flow rate, and damper size, can reach up to 150°C. Meanwhile, the rotor’s rotation loosens the powder, forming a vortex two – phase flow, enabling the surface modifier to quickly and evenly coat the powder particles.

Performance characteristics

Good dispersibility of powder and surface modifier, the modified product not only has no agglomerated particles, but also has a certain deagglomeration effect on the agglomerated particles in the raw materials; Continuous metering matching feeding and dosing (modifier) ​​powder and surface modifier action plan are equal, the powder surface is evenly embedded, and the product embedding rate is high; Low energy consumption The energy consumption of each product used for ultrafine light calcium carbonate modification is below 35KWh/t; No dust pollution, the system is closed-loop and negative pressure operation, and equipped with dust removal device; Continuous production, high degree of automation, simple operation and stable operation.

Scope of application

Applicable to continuous mass production of inorganic active fillers and pigments such as heavy calcium carbonate, light calcium carbonate, kaolin, zinc oxide, magnesium hydroxide, strong aluminum oxide, sericite, barium sulfate, white carbon black, talc, etc. It can be combined with dry grinding process, such as ultrafine grinding process, and can also be set separately for surface modification of various ultrafine powders and deagglomeration and surface modification of nano powders.

Light calcium carbonate Light calcium is widely used in plastic products, coatings, inks and other fields. In order to improve the compatibility with organic polymer materials and the dispersibility in the system in these application fields, and to improve the comprehensive performance of the filled or compounded products, it is necessary to modify the surface of light calcium. Since the surface modifier is produced continuously and has a dust collection system, it has the advantages of less material loss and less dust pollution compared with the modification of light calcium with a high-speed heating mixer.
