CLIRIK offers a comprehensive range of fly ash grinding systems. Our technology is designed to optimize your production efficiency, significantly reduce specific energy consumption, and meet the most stringent manufacturing requirements for various fly ash-based products.
Material Introduction
Fly ash consists primarily of glassy, spherical particles formed when the mineral impurities in coal fuse during combustion and then cool rapidly. Chemically, it is composed mainly of silica (SiO2), alumina (Al2O3), and iron oxide (Fe2O3). Based on its calcium content, it is categorized into Class F (low calcium) and Class C (high calcium).
The most defining industrial trait of fly ash is its “ball-bearing” effect, where its perfectly spherical micro-beads improve the fluidity and workability of concrete mixes. Physically, it has a Mohs hardness of 5–6 in its glassy phase and features a low bulk density. Its pozzolanic activity allows it to react with calcium hydroxide in cement to form additional strengthening compounds. Once processed into ultra-fine powder, fly ash significantly enhances the density and impermeability of materials. Its performance is defined by its fineness and loss on ignition (LOI), which are critical for ensuring the long-term durability and chemical resistance of advanced composite structures.

Industrial Applications
1
200 – 400 Mesh (D97: 75-38μm): Standard Concrete & Infrastructure
Applications :
Primarily used as a supplementary cementitious material for Ready-Mix Concrete, road foundations, and mass concrete projects like dams.
Advantages :
It reduces the heat of hydration, preventing thermal cracking in large structures. It also improves the long-term strength and pumpability of the concrete mix.
2
800 – 1250 Mesh (D97: 18-10μm): High-Strength Mortar & Grouting
Applications :
Essential for High-Performance Mortars, specialized grouting materials, and high-strength precast concrete components.
Advantages :
At this fineness, the “filler effect” becomes more pronounced, creating a denser micro-structure that significantly increases the resistance to sulfate attack and chloride penetration.
3
1500 – 2500 Mesh (D97: 10-5μm): Polymer Fillers & Rubber Compounds
Applications :
Used as a functional filler in Plastic Composites, rubber floor mats, and automotive sound-deadening materials.
Advantages :
The increased surface area and spherical shape allow for high loading levels with minimal impact on resin viscosity. It enhances the dimensional stability and surface finish of the final polymer products.
4
3000 Mesh + (D97: ≤5μm): Specialized Coatings & High-End Plastics
Applications :
Specialized functional material for Anti-Corrosion Coatings, powder coatings, and precision engineering plastic components.
Advantages :
The ultra-fine particle size ensures perfect dispersion and a nanometer-level finish. In coatings, it creates a dense barrier layer that protects against chemical erosion and improves the scratch resistance of the surface.
