In recent years, the paper-making industry in Algeria has experienced a strong demand for innovative raw materials and environmentally friendly processing technologies. Basalt, a volcanic rock of exceptional hardness and durability, has emerged as an interesting mineral for use in paper production. When ground into fine powder (around 80 mesh), basalt can be utilized as a filler or coating material to improve the strength, whiteness, and durability of paper. To achieve such a fine and consistent powder, a reliable and efficient grinding system is essential. This is where Shanghai Zenith Machinery Co., Ltd. plays an important role.
Basalt possesses high silica and alumina content, giving it excellent chemical stability and mechanical strength. When processed into fine powder, it can act as a substitute for traditional mineral fillers like calcium carbonate or kaolin in paper production. This reduces costs and enhances the final product’s resistance to wear and moisture.
In modern paper manufacturing, the addition of mineral fillers helps to:
For these reasons, the demand for high-quality basalt powder around 80 mesh has increased in industrial paper lines across Algeria. However, grinding basalt—a hard and dense material—requires advanced processing technology, high-efficiency classifiers, and stable mechanical construction. This is why selecting the appropriate grinding mill is critical.
To produce basalt powder suitable for paper making, the targeted fineness is usually within 75–90 mesh. At this range, basalt offers a balance between surface smoothness and particle bonding in the paper pulp. Key requirements for the grinding process include:
Basalt’s Mohs hardness of about 6–7 makes it more challenging to process than softer minerals. Therefore, mills with advanced internal design, robust wear-resistant materials, and efficient classifiers are required for economic production.
Shanghai Zenith Machinery Co., Ltd. is a distinguished Chinese manufacturer in the field of ore and industrial powder grinding equipment. With decades of innovation and technology advancement, Zenith provides integrated systems that can produce powders from coarse to ultrafine grades. For basalt grinding in Algeria targeting 80 mesh, two of Zenith’s models stand out: the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill. These machines are known for their high precision, durability, and energy efficiency.
The MTW Trapezium Grinding Mill integrates advanced European technology and is ideal for medium-hard materials like basalt. It provides stable performance, high output, and precise fineness control. The air circulation and dust isolation design contribute to a clean production environment suitable for paper filler applications.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110Z | <30 | 1.6–0.045 | 3–10 | 55 | 55 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
The MTW mill is an excellent solution when consistent fineness and high throughput are required. Its trapezoidal structure and adjustable classifier make it easy to produce basalt powders in the 80-mesh range for industrial paper lines.
For customers seeking integrated grinding and drying systems, the LM Vertical Grinding Mill is a highly efficient choice. This machine combines crushing, grinding, powder classification, drying, and material transportation in a single system—making it particularly suitable for large-scale basalt grinding plants in Algeria where climate conditions and moisture control are important.
One outstanding feature of the LM Vertical Mill is its energy savings—up to 30% compared to traditional ball mills. It also offers consistent particle distribution with adjustable fineness between 170 µm to 40 µm, making 80-mesh production effortless and stable.
| 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 |
Compared to conventional mills, LM Vertical Grinding Mills reduce dust emission and noise while offering an integrated approach to process control. They are ideal for environmentally conscious paper product manufacturers in Algeria who prioritize sustainability and energy efficiency.
