Ethiopia’s mining sector is rapidly expanding, with quartz deposits playing a vital role in the production of metallurgy flux. Metallurgical flux, typically composed of high-purity quartz (SiO₂ ≥ 98%), is essential in smelting processes to lower melting points and remove impurities. For Ethiopian mining and mineral processing companies, selecting the right grinding mill for quartz to achieve the required fineness (typically 0.1–0.5 mm) is crucial. This article provides a comprehensive technical guide to grinding equipment that delivers stable, efficient processing of quartz for flux applications at a capacity of 1–3 tons per hour (TPH), focusing on solutions from Shanghai Zenith Machinery Co., Ltd., a renowned manufacturer of ore grinding equipment in China.
Quartz used as a metallurgical flux must be ground to a consistent particle size to ensure uniform reaction in furnaces. The typical feed size from primary crushers ranges from 10–30 mm, and the target product is often 0.5–2 mm (coarse) or 0.1–0.5 mm (fine). In Ethiopia, many small to medium-scale plants operate with throughputs of 1-3 tph, demanding robust, energy-efficient, and low-maintenance mills. Key factors include moisture content (below 5%), abrasiveness due to high silica content (Mohs hardness 7), and the need for continuous operation.
Based on extensive experience in the field of ultra-fine powder grinding, Shanghai Zenith Machinery offers two highly suitable models for this capacity range: the MTW Trapezium Grinding Mill and the MTM Medium-Speed Grinding Mill. Both are engineered to handle hard, abrasive materials like quartz while maintaining low operating costs.
The MTW series is a premium grinding mill with multiple patents, recognized for its compact structure, long service life, and eco-friendly design. It is particularly effective for quartz grinding due to its trapezium-shaped grinding rollers and ring, which increase grinding efficiency and reduce vibration. The MTW110 model, with a capacity range of 3–9 t/h, can be accurately tuned to operate at the lower end of its band (1–3 t/h) by adjusting classifier speed and feed rate, making it an ideal choice for Ethiopian flux production lines.
| Parameter | Value |
|---|---|
| Max. Feed Size | <30 mm |
| Final Product Size | 1.6 – 0.045 mm (can be adjusted to 0.5-2 mm for flux) |
| Capacity | 3 – 9 t/h (optimized to 1-3 t/h at reduced classifier speed) |
| Main Motor Power | 55 kW |
| Fan Motor Power | 55 kW |
| Overall Dimension (L×W×H) | 7.5×5.0×5.5 m |
The MTM series adopts world-leading powder processing technology and is an ideal substitute for traditional Raymond mills. The MTM100 model features a robust design with multiple grinding rings (4 rolls) and is engineered for high-efficiency processing of medium-hard minerals like quartz. Its capacity range of 3–8 t/h allows flexible operation at 1-3 tph by controlling the feed rate and speed; moreover, its low power consumption (main motor only 37 kW) makes it a cost-effective solution for budget-conscious Ethiopian operators.
| Parameter | Value |
|---|---|
| Ring Roll Number | 4 pcs |
| Max. Feed Size | <25 mm |
| Output Capacity | 3 – 8 t/h (adjustable to 1-3 t/h) |
| Main Unit Motor Power | 37 kW |
| Final Product Fineness | 1.6 – 0.045 mm |
| Weight (approx.) | 15 t |
When choosing between MTW110 and MTM100 for a 1-3 tph quartz metallurgy flux line, consider these factors:
For operators seeking a slightly more robust, long-life solution, the MTW110 is recommended. For those prioritizing lower initial investment and energy costs, the MTM100 is an excellent choice. Both models can achieve the required flux fineness (0.5–1.5 mm) with classifier adjustment.
Ethiopian quartz often contains impurities like iron oxide, which can discolor the flux. Both the MTW and MTM mills allow for dry grinding with optional magnetic separation before or after the mill. Additionally, the dry process eliminates water usage – a critical advantage in arid regions. The mills also incorporate advanced dust collection systems (bag filters) to meet environmental standards.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China, with decades of experience in the field of ultra-fine powder grinding. Our mills are designed for extreme durability and efficiency. We provide complete after-sales support including installation, training, and spare parts supply. Many customers in Africa, including Ethiopia, have successfully deployed our MTW and MTM series for limestone, gypsum, and quartz processing. Our engineers can also customize the mill configuration to match local power conditions (e.g., 50 Hz, 380 V) and altitude adjustments.
For Ethiopian companies requiring a quartz grinding mill for metallurgy flux at 1-3 tph, the MTW Trapezium Grinding Mill (MTW110) and the MTM Medium-Speed Grinding Mill (MTM100) represent the most reliable and cost-effective options. Their proven track record with abrasive materials, flexible capacity adjustment, and low operating costs make them the preferred choice for building a sustainable flux production line.
