1. Introduction
The modification of calcium carbonate (CaCO₃) is a critical process in industries of plastics, rubber, coatings and paper, etc. In these fields, particle size, surface properties and dispersion of powders are essential for optimizing product performance. As a manufacturer of pin mill for many years, pin-mill produced by Qingdao Epic Powder Machinery Co., Ltd excels in the performance of modified calcium carbonate. In this article, we will focus on the advantages of pin mill in calcium carbonate modification.
2. Advantages of pin mill in calcium carbonate modification
Pin mill operates through high-speed impact and shearing force generated by rotating pins and stator. This enables ultra-fine grinding and surface activation of particles. For calcium carbonate, this mechanism meets the requirements of smooth discharge and high production capacity. This is the key reason why pin mill is used for calcium carbonate modification.
Smooth discharging
- The polar groups on the surface of calcium carbonate particles modified by pin mill are covered by organic groups, which weakens the interaction between the particles, and makes it easier to disperse evenly in matrix such as resin. This helps improve the fluidity of the particles and ensures smooth discharge.
Production capacity increasing
- Pin- mill is a commonly used ultra-fine powder processing equipment. It is mainly used for ultra-fine grinding and surface modification of materials. It can realize the integrated operation of grinding and modifying, thereby shortening the production cycle and reducing labor and energy costs.
In addition, the pin-mill modification can be used in both laboratory and small batch production as well as large-scale continuous production. Moreover, the modification rate of up to 99%, higher than other modifying equipment.
3. Market potential
Calcium carbonate modified by pin-mill has a wide range of application, e.g: plastics, coatings, and rubber, it can significantly improve the quality and performance of the products. As the demand for high-performance calcium carbonate in various industries continues to increase, the market demand for pin- mill will continue to expand, and the market potential is huge.
