Algeria is a country with abundant geological resources. Basalt, formed from volcanic activity, is found in many regions of the country and remains largely underutilized. In recent years, the Algerian plastics industry has grown rapidly, creating new demand for high-quality mineral fillers. A basalt grinding mill for plastic filler in Algeria at 1000 mesh represents a promising business opportunity. Converting local basalt into superfine powder can replace imported fillers, create local jobs, and add value to domestic minerals.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China, with deep expertise in ultra-fine powder grinding. Our product portfolio includes MTW trapezium mills, ball mills, MTM medium-speed mills, Raymond mills, LM vertical mills, LUM ultrafine vertical mills, XZM ultrafine grinding mills, and hammer mills. Among them, the XZM ultrafine grinding mill is especially suitable for producing 1000-mesh basalt powder for use as a plastic filler.
Mineral fillers are widely used in plastic products to reduce cost and to modify physical properties. Common fillers include calcium carbonate, talc, kaolin, and barium sulfate. Basalt powder is less common but offers several advantages. Basalt has high hardness, high compressive strength, good thermal stability, and low water absorption. When ground to a fine particle size, it can improve the rigidity, heat resistance, and wear resistance of plastic composites.
Basalt powder is especially interesting for applications such as automotive parts, electrical enclosures, pipes, and packaging. It can be blended into polypropylene, polyethylene, PVC, and nylon. The dark color of basalt must be considered, but in black or dark-colored plastic products it is perfectly acceptable. With a fineness of 1000 mesh, basalt powder disperses evenly in the polymer melt and can reduce the shrinkage of molded parts.
Mesh size is a measure of particle fineness. A 1000-mesh powder means that the particles can pass through a sieve with 1000 openings per linear inch. The nominal particle size is approximately 13 microns. For plastic filler applications, such a fine particle size helps to achieve good surface finish and consistent mechanical properties. Coarse particles may cause stress concentration and reduce impact strength. Therefore, the grinding mill must be able to produce a stable and narrow particle size distribution at a high throughput.
Reaching 1000 mesh from raw basalt is not trivial. The process requires efficient crushing, fine grinding, accurate classification, and effective dust collection. A mill that can achieve this fineness while maintaining reasonable energy consumption will give a producer a strong competitive edge.
Basalt is one of the harder rocks used in powder processing. Its Mohs hardness ranges from 5.5 to 7.0. This means that grinding tools are subject to severe abrasion. Additionally, basalt can contain silica-rich minerals that further increase wear. To make the project profitable, the grinding mill must feature wear-resistant materials, a robust structure, and low maintenance requirements.
Another challenge is moisture. For dry ultra-fine grinding, the raw material moisture should be below 6%. In Algeria, dry basalt is usually available, but storage and handling should avoid undesired hydration. The grinding system must also have a powerful air classifier. For 1000-mesh powder, the classifier must be precise enough to reject oversized particles and prevent product contamination.
For a plant aiming at 1000-mesh basalt powder, the XZM Ultrafine Grinding Mill is the most straightforward choice. The XZM mill is a well-proven machine for superfine powder production in the range of 325-2500 mesh. It is widely used in the production of mineral powder, including calcium carbonate, barite, and bentonite. With structural improvements and proper configuration, it can also be used for basalt.
The mill operates on the principle of medium-speed grinding. Raw material is fed into the grinding chamber and crushed between the grinding roller and grinding ring. A high-efficiency classifier adjusts the fineness. The whole system is under negative pressure, which ensures clean operation. The moisture content in the feed should be below 6% to avoid clogging.
Zenith offers two main models in the XZM series: XZM221 and XZM268. The following table shows their core specifications.
| 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 |
For a medium-capacity plant in Algeria, the XZM221 can produce roughly 500-4500 kg/h depending on the hardness of the basalt and the target fineness. For large-scale production, the XZM268 offers substantially higher throughput.
The production process includes several stages. First, raw basalt is crushed by a jaw crusher or impact crusher to a size below 20 mm. Second, the crushed material is transported by a bucket elevator to a storage bin. Third, a vibrating feeder delivers the material at a controlled rate into the XZM mill. Inside the mill, the basalt is ground to the desired fineness. The airflow carries the ground powder to the classifier. Oversized particles are returned to the grinding chamber. Qualified fine powder enters the cyclone collector and bag filter. Finally, the product is packed.
Zenith can supply all the auxiliary equipment, including crushers, feeders, conveyors, and dust collectors. This turnkey approach makes it easier for investors in Algeria to start a complete basalt powder production line.
In addition to the XZM series, Zenith offers the LUM Ultrafine Vertical Mill. This machine integrates grinding, drying, classifying, and conveying. It has a smaller footprint and can handle larger feed sizes. The LUM series is also capable of producing powder with D97 in the range of 5-30 micrometres, which corresponds to approximately 300-2500 mesh. Therefore, it is a good alternative when the project requires high capacity and low energy consumption.
For basalt with a feed size of up to 20-30 mm, the LUM mill can simplify the upstream crushing process. Its intelligent control system makes operation stable and maintenance easy. The final powder quality is consistent, which is essential for the plastic filler industry.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220-250 | 1.6-11.5 | 5-30 |
| LUM1632 | 280-315 | 2.0-13.5 | 5-30 |
| LUM1836 | 355-400 | 2.3-15 | 5-30 |
When choosing between XZM and LUM, the decision depends on raw material conditions, capacity targets, and available floor space. Zenith can provide a free process evaluation for basalt mining companies and filler producers in Algeria.
