The paper industry in Ivory Coast, a vital sector for both domestic consumption and export, is undergoing significant modernization. A key component in enhancing paper quality, particularly for printing and writing grades, is the use of bentonite clay. Bentonite acts as an excellent retention and drainage aid, improves sheet formation, and enhances the efficiency of other wet-end chemicals. To unlock these benefits, the bentonite must be processed into a fine, consistent powder. This necessitates reliable, efficient, and precise grinding technology capable of meeting the specific demands of a growing market. For a production line targeting 20-30 tons per hour (TPH) of processed bentonite, selecting the optimal grinding mill is paramount to operational success and profitability.
Grinding bentonite for papermaking is not merely about size reduction; it’s about achieving specific physical and chemical properties. The process demands:

Operating in Ivory Coast presents unique considerations. Reliable after-sales support, equipment durability to withstand local climate conditions, and operational simplicity are as important as technical specifications. The chosen mill must offer:
After a thorough analysis of the requirements for a 20-30 TPH bentonite processing plant in Ivory Coast, Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer renowned for its achievements in ultra-fine powder grinding, offers an ideal solution. Among their comprehensive range of industrial powder grinding equipment, the LM Vertical Grinding Mill stands out as the most suitable technology for this application.
The LM Vertical Mill integrates five functions—crushing, grinding, powder selection, drying, and material conveying—into a single, compact unit. This integration is perfect for the Ivorian project, saving plant space and simplifying the process flow. Its ability to efficiently dry and grind simultaneously addresses moisture control challenges. Furthermore, its grinding mechanism, involving a rotating grinding table and rollers, produces less metal-to-metal contact than traditional ball mills, resulting in lower iron contamination—a critical factor for paper-grade bentonite.
For a 20-30 TPH bentonite grinding project, the LM190K model is highly recommended. Its parameters align perfectly with the production target and quality requirements.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 | <38 | 200 |
| LM190K | 1900 | 23-68 | 170-40 | <45 | 500 |
| LM280K | 2800 | 50-170 | 170-45 | <50 | 1250 |
The LM190K reliably operates within the 20-30 TPH range while easily achieving the required 200-325 mesh fineness (approximately 44-74 microns). Its high capacity margin also ensures the system is not overstressed, promoting longer service life and stability.

For projects with slightly different priorities or as a complementary system for other minerals, Shanghai Zenith’s MTW Trapezium Grinding Mill is another excellent option. Known for its multiple patents, compact structure, and eco-friendly design, it is a versatile workhorse. For the lower end of the 20-30 TPH range, the MTW175G model is a strong contender.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 |
| MTW175G | <40 | 1.6-0.045 (~325 mesh) | 9.5-25 | 160 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 |
The MTW175G offers a cost-effective and highly efficient solution, particularly where space is a constraint. Its curved air duct design reduces air flow resistance and increases production efficiency.
Establishing a 20-30 TPH bentonite grinding plant is a strategic investment for the paper industry in Ivory Coast. The choice of grinding technology directly impacts product quality, production cost, and plant reliability. Shanghai Zenith Machinery Co., Ltd., with its specialization in research, development, and production of industrial grinding equipment, provides not just machines, but tailored solutions. The LM190K Vertical Grinding Mill emerges as the premier recommendation for its integrated drying-grinding capability, suitable capacity, and low contamination risk. The MTW175G Trapezium Mill presents a robust alternative. By partnering with Zenith, Ivorian paper manufacturers gain access to world-class technology backed by professional support, paving the way for enhanced product quality and strengthened competitiveness in regional and global markets.
