The Kenyan industrial sector has witnessed significant growth in recent years, particularly in the rubber manufacturing industry. One critical component in rubber production is the use of mineral fillers to enhance product properties and reduce manufacturing costs. Basalt, a common volcanic rock found abundantly in Kenya, has emerged as an excellent filler material for rubber compounds. This article explores the technical requirements and optimal solutions for grinding basalt to 80 mesh specifications for rubber filler applications in Kenya.
Basalt possesses several characteristics that make it ideal for rubber filler applications. Its hardness, chemical stability, and abundance in Kenya make it a cost-effective alternative to traditional fillers. When ground to 80 mesh (approximately 180 microns), basalt particles provide excellent reinforcement to rubber compounds, improving tensile strength, tear resistance, and durability while maintaining flexibility.
The 80 mesh specification is particularly crucial for rubber filler applications. Finer particles ensure better dispersion within the rubber matrix, leading to improved mechanical properties and surface finish. Coarser particles, on the other hand, may compromise the integrity of the final rubber product.

Grinding basalt to precisely 80 mesh presents several technical challenges that require specialized equipment:
After extensive research and field testing, Shanghai Zenith Machinery Co., Ltd. has identified the most suitable grinding solutions for basalt processing in Kenya. Our expertise in industrial powder grinding equipment positions us uniquely to address the specific requirements of the Kenyan rubber industry.
For basalt grinding applications targeting 80 mesh output, the MTW Trapezium Grinding Mill stands out as the optimal solution. This advanced grinding mill incorporates multiple patented technologies that make it particularly suitable for processing hard materials like basalt while maintaining precise particle size control.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Suitable for 80 Mesh Output |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6-0.045 | 3-9 | 55 | Yes |
| MTW110Z | <30 | 1.6-0.045 | 3-10 | 55 | Yes |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | Yes |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | Yes |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 | Yes |
The MTW series excels in basalt processing due to its curved surface shovel, which increases material feeding capacity by 30-40% compared to traditional straight shovels. The bevel gear overall transmission ensures smooth operation and precise control over the final particle size, crucial for achieving the consistent 80 mesh output required for rubber filler applications.

For operations requiring flexibility in production or potential future expansion into finer powder applications, the XZM Ultrafine Grinding Mill presents an excellent alternative. While capable of producing much finer powders (up to 2500 mesh), it can be precisely calibrated to maintain consistent 80 mesh output for basalt rubber filler.
| Model | Working Diameter (mm) | Max Feed Size (mm) | Final Size (mesh) | Output (kg/h) | Main Motor Power (kW) |
|---|---|---|---|---|---|
| XZM221 | Φ800 | ≤20 | 325-2500 | 500-4500 | 75 |
| XZM268 | Φ1680 | ≤20 | 325-2500 | 5000-25000 | 315 |
