Mechanical Fusion Machine Modification Process

It adopts a batch operation mode, which is suitable for the modification scenarios of additives such as silanes that require high temperature and long reaction time.

This equipment adopts a batch operation mode, making it particularly suitable for the modification scenarios of calcium carbonate powder with additives such as silanes that require high temperature and long reaction time. It is equipped with built-in heating and timing devices to precisely control the temperature and reaction duration of calcium carbonate modification. The inner lining can be made of optional ceramic materials to achieve zero metal contamination of calcium carbonate powder. It drives the full mixing and integration of calcium carbonate materials and modifiers through mechanical force, enhancing the coating modification effect.

How it works

Both horizontal and vertical compounders adopt a cylindrical cavity structure with top feeding and bottom discharging, which are specially designed for the modification of calcium carbonate powder. The horizontal compounder is equipped with dispersing blades arranged at alternating angles. During high-speed rotation, it can quickly break up calcium carbonate materials, making them fully dispersed and spheroidized under the action of repeated alternating stress and extrusion force. Meanwhile, it generates heat through intense friction to efficiently complete surface coating modification. The vertical compounder uses the centrifugal force of the rotating drum to throw calcium carbonate materials toward the drum wall. Under the strong extrusion between the drum inner wall and the arc-shaped pressure knife, the surface temperature of material particles rises rapidly and mechanical force is obtained, so as to achieve uniform and stable modification effect and meet the processing requirements of different calcium carbonate powders.

Performance and features

Temperature and Time Controllable

Equipped with professional heating and timing functions, the modification temperature and reaction time can be precisely adjusted. It can flexibly meet the modification reaction requirements of different calcium carbonate powders such as precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC), ensuring a stable and controllable modification process.

Wide Application Range

It can achieve ideal activation and modification effects for various inorganic mineral powders through mechanical fusion. It is especially suitable for calcium carbonate powders of different mesh sizes and types, fully improving their surface activity to satisfy diverse processing needs.

Adequate Coating

Relying on the coordination of uniform feeding and quantitative feeding of modifiers, combined with the strong mixing effect of mechanical fusion, it enables full contact between modifiers and calcium carbonate particles, ensuring each powder particle is adequately coated and improving product consistency.

Thorough Reaction

Through the system’s precise control of temperature and time, coupled with the auxiliary enhancement of mechanical force, it provides optimal conditions for the modification reaction of calcium carbonate powder, ensuring the coating reaction between modifiers and powder particles proceeds fully and enhancing the performance of the finished powder.

Binder-Free Surface Coating, Streamlined Process with Controllable Purity

It can achieve uniform surface coating of calcium carbonate particles with different particle sizes without adding any binders. While simplifying the production process, it avoids the introduction of external impurities, ensures the purity of calcium carbonate powder, and improves the stability and reliability of modification processing.
