Algeria’s industrial sector, particularly rubber manufacturing, is witnessing significant growth. A key component in enhancing rubber product properties such as tensile strength, abrasion resistance, and dimensional stability is the use of high-quality mineral fillers. Expanded perlite, when ground to a precise fineness, serves as an excellent, cost-effective filler. The challenge lies in processing raw perlite into a consistent, ultra-fine powder, specifically targeting the industry-standard 200 mesh (approximately 74 microns). This demands robust, efficient, and precise grinding technology.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore grinding equipment, has made great achievements in the field of ultra-fine powder grinding. Specializing in the research, development, and production of industrial powder grinding equipment, Zenith offers tailored solutions for mineral processing challenges like perlite grinding for rubber filler applications.
Perlite possesses unique characteristics that present specific challenges for milling. Its abrasive nature can cause rapid wear on grinding components. Furthermore, achieving a uniform 200-mesh product without over-grinding—which can compromise the particle structure and performance in rubber—requires mills with precise classification systems. Energy efficiency and low maintenance are also critical for cost-effective operations in Algeria.
For the specific application of producing 200-mesh perlite powder for rubber filler, two of Zenith’s product lines stand out due to their efficiency, precision, and reliability.
The Zenith XZM Ultrafine Grinding Mill is engineered for producing superfine powders from soft to medium-hard materials. Its integrated dynamic classifier ensures precise particle size control, making it ideal for achieving the tight 200-mesh specification. The mill’s design minimizes over-grinding and is highly effective for low-moisture materials like calcined perlite.
| 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 |
The XZM series, particularly the XZM221 model, is perfectly suited for medium-scale production in Algeria. Its ability to reliably produce powder in the 200-2500 mesh range covers the target fineness with room for future product diversification.
For larger-scale operations requiring high throughput of 200-mesh perlite, the Zenith MTW Trapezium Grinding Mill is the optimal choice. Known for its multiple patents, compact structure, and curved shovel blade design that increases feeding capacity, the MTW mill offers exceptional stability and long service life—a crucial factor when processing abrasive materials.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 (approx. 10-325 mesh) | 6-17 | 90 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
The MTW175G model provides an excellent balance between high capacity (up to 25 t/h) and the ability to fine-tune output down to 200 mesh (0.074mm). Its advanced internal separator ensures product consistency, making it a robust backbone for major rubber filler production lines.
Implementing Zenith grinding mills translates into tangible benefits:
The successful production of 200-mesh perlite filler is pivotal for Algeria’s rubber industry to manufacture competitive, high-quality products. Shanghai Zenith Machinery Co., Ltd., with its deep expertise and proven product portfolio—from the precise XZM Ultrafine Mill to the high-capacity MTW Trapezium Mill—provides the technological foundation for this success. By choosing Zenith’s reliable and efficient grinding solutions, Algerian enterprises can achieve superior product quality, operational efficiency, and sustainable growth in the global market.
