Algeria’s livestock industry has been expanding rapidly over the past decade, driven by rising domestic consumption of meat, dairy, and poultry products. To maintain animal health and productivity, farmers and feed manufacturers are increasingly turning to natural mineral supplements. Among these, basalt – a volcanic rock rich in essential trace elements such as iron, magnesium, calcium, silicon, and potassium – has gained significant attention as an animal feed additive. Ground basalt powder provides a slow-release source of minerals that improve bone density, enzyme function, and overall immune response in animals. The typical fineness required for feed applications is 150 mesh (approximately 100 microns), which ensures optimal mixing homogeneity and digestibility. This article explores the technical considerations for selecting a basalt grinding mill for this specific application in Algeria, and recommends industry-leading solutions from Shanghai Zenith Machinery Co., Ltd., a premier Chinese manufacturer of ore grinding equipment with extensive experience in ultra-fine powder processing.
The particle size of mineral feed additives directly influences their bioavailability and efficacy. For basalt, 150 mesh (<100 µm) strikes an ideal balance between surface area and flowability. Finer particles (<50 µm) may cause dusting issues and over-exposure, while coarser particles (>200 µm) reduce absorption rates. At 150 mesh, the basalt powder can be easily blended with other feed components without segregation, and the minerals are gradually released in the digestive tract. In Algeria, where feed mills often operate under varying humidity conditions, a consistent 150-mesh product also ensures stable production and shelf life. Therefore, investing in a reliable grinding system that can achieve this specification with high throughput and low energy consumption is critical for both cost-effectiveness and product quality.

Selecting the right grinding equipment for basalt in Algeria involves several considerations:
Shanghai Zenith’s portfolio includes several mills that meet these demands, with the MTW Trapezium Grinding Mill and MTM Medium-Speed Grinding Mill being particularly well-suited for basalt grinding at 150 mesh.
The MTW series is a patented trapezium mill that combines crushing, grinding, and classification in one compact system. Its unique trapezium-shaped rollers and ring create a multi-stage grinding effect, which is highly efficient for hard materials like basalt. The mill is equipped with an advanced classifier that provides precise particle size control, ensuring that 150 mesh (0.1 mm) is achieved consistently. Key advantages for the Algerian animal feed industry include:
For a typical Algerian operation targeting 5-10 t/h of basalt powder at 150 mesh, the MTW110Z or MTW138Z models are ideal choices. Below is the technical specification table for the MTW series with emphasis on models suitable for this application.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6-0.045 | 3-9 | 55 | 55 |
| MTW110Z | <30 | 1.6-0.045 | 3-10 | 55 | 55 |
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 | 315 |
Note: “Final Size” range includes 0.045 mm (325 mesh), so adjusting the classifier easily yields 150 mesh (0.1 mm). The ‘Z’ models feature an upgraded main shaft and gearbox for enhanced durability.

The MTM medium-speed mill is another excellent candidate, especially for operations with moderate capacity and budget constraints. It is designed as a direct upgrade to traditional Raymond mills, offering higher efficiency and a smaller footprint. The grinding principle involves three rollers pressing against a ring, with a built-in classifier ensuring uniform product fineness. For basalt at 150 mesh, the MTM series delivers stable performance with the following benefits:
The MTM100 and MTM130 models are particularly recommended for small to medium basalt feed additive lines in Algeria. Their technical parameters are listed below.
| Model | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Motor Power (kW) |
|---|---|---|---|---|
| MTM100 | 4 | <25 | 3-8 | 37 |
| MTM130 | 5 | <30 | 6-11 | 75 |
| MTM160 | 6 | <35 | 9-22 | 132 |
For example, an Algerian customer producing 6-8 t/h of 150 mesh basalt powder would find the MTM130 an optimal match, with a main motor of only 75 kW and a compact footprint that fits into existing feed mill layouts.
Both the MTW and MTM mills are technically capable of producing 150 mesh basalt, but the choice depends on specific project requirements. The MTW series generally offers higher capacity ranges and more advanced dust control, making it suitable for larger continuous operations. The MTM series, on the other hand, is more economical for smaller throughputs and simpler installations. In Algeria, where many feed mills are expanding from traditional lines, the MTM130 provides a low-risk, proven solution. However, for new large-scale factories aiming to export basalt-based feed additives, the MTW138Z or MTW175G would deliver higher efficiency and lower operating cost per ton. Both mills are backed by Shanghai Zenith’s global service network, with spare parts available through regional distributors in Algeria and neighboring countries.
Algeria’s climate varies from Mediterranean coast to Saharan desert, and site conditions can affect mill performance. For coastal installations, corrosion resistance of mill components is important – Shanghai Zenith uses high-grade steel and optional anti-corrosion coatings. In inland desert areas, dust ingress into bearings must be prevented; both MTW and MTM have sealed bearing arrangements and centralized lubrication systems. Additionally, the availability of electricity in remote areas may influence motor selection – the MTW series offers optional soft-start and frequency converters to handle voltage fluctuations. Maintenance staff should be trained on wear part replacement intervals; for basalt, grinding rollers and rings typically need replacement every 6-12 months depending on throughput. Shanghai Zenith provides comprehensive manuals and after-sales support to ensure long-term reliability.
Basalt grinding for animal feed additives at 150 mesh represents a growing niche in Algeria’s agricultural sector. By choosing a high-performance mill from a proven manufacturer, feed producers can achieve consistent product quality, reduce energy costs, and enhance animal nutrition. Shanghai Zenith Machinery Co., Ltd. offers two outstanding solutions – the MTW Trapezium Grinding Mill and the MTM Medium-Speed Grinding Mill – both capable of meeting 150 mesh specifications with excellent efficiency. The company’s decades of experience in ore grinding, combined with its commitment to innovation and customer support, make it the ideal partner for Algerian enterprises venturing into mineral feed additives.
