Australia is one of the world’s largest producers of drilling equipment and raw materials for energy exploration. In industries such as oil and gas, mining, and geotechnical engineering, drilling mud plays an essential role in cooling and lubricating the drill bit, stabilizing boreholes, and carrying rock cuttings to the surface. One of the critical raw materials in high-performance drilling muds is basalt powder. To produce basalt powders with the precise particle size distribution required for efficient drilling performance, high-quality grinding mills with reliable capacity are indispensable.
Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of industrial grinding equipment, has established itself as a trusted partner in the field of mineral processing. With decades of experience in powder engineering and advanced mechanical design, Zenith offers a comprehensive range of grinding systems tailored for different applications, from coarse to ultrafine powders. This article focuses on the selection, design, and implementation of basalt grinding mills suitable for drilling mud production at a capacity of 20–30 tons per hour (TPH) in Australia.
Basalt, an igneous rock formed from rapid cooling of lava, is known for its high strength, hardness, and chemical stability. When finely ground, basalt can be added to drilling fluids to improve their rheological properties, increase the density, and reduce filtration losses. Fine basalt particles enhance the plugging effect in porous formations, thus improving drilling efficiency and wellbore stability.
For these applications, achieving a uniform particle size distribution (typically 45–100 microns) is crucial. This requirement calls for energy-efficient and precise grinding equipment, capable of processing hard minerals continuously within a fineness control range suitable for drilling applications.
Basalt presents particular grinding challenges due to its high hardness (5–6 on the Mohs scale) and abrasive nature. In addition, Australian mining operations often require high throughput under strict environmental standards, emphasizing energy efficiency, dust control, and automation.
Given that the target production capacity is 20–30 TPH, the right selection of grinding mill is essential to balance between performance, energy consumption, and maintenance costs. Shanghai Zenith provides multiple solutions such as the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill, both of which are proven choices for basalt processing.
The MTW Trapezium Grinding Mill is a modernized grinding solution suitable for medium-hard materials like basalt. It integrates advanced European technology and is renowned for its efficient powder production, low operating costs, and environmentally friendly design. For basalt grinding applications demanding a 20–30 TPH output, models such as MTW175G or MTW215G are highly recommended.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
| MTW215G | <50 | 1.6–0.045 | 15–45 | 280 | 315 |
These models can efficiently meet the 20–30 TPH requirement for basalt powder production, offering consistent output quality suitable for drilling mud applications. The trapezium structure ensures high grinding efficiency with lower vibration and noise, improving the workplace environment. Moreover, MTW mills adopt a unique curved blade design that ensures even material flow and enhanced grinding performance.
For projects prioritizing integrated operations (crushing, grinding, drying, and classification), the LM Vertical Grinding Mill provides a more compact and energy-efficient option. This type of mill is ideal for both primary grinding and fine powder production, and it performs exceptionally well when moisture control is needed — an important advantage for drilling mud materials that may require drying stages before packaging or mixing.
| 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 |
The LM190K model offers an ideal throughput range for basalt grinding in drilling mud production. It allows precise control of fineness, improves grinding uniformity, and reduces operational downtimes with its integrated design. The vertical configuration minimizes footprint and power consumption, making it highly suitable for regional Australian processing facilities where energy savings are crucial.
For a production line targeting 20–30 TPH, the typical system layout may include:
Zenith’s engineering team provides turnkey design and on-site installation supervision to ensure optimal integration of all these components. This ensures that the production system achieves stable performance, consistent output, and easy maintenance, even under challenging Australian working environments.
The following are the major advantages of adopting Zenith basalt grinding mills for drilling mud production:
In Western Australia, a customer from an offshore exploration company deployed an MTW215G-based grinding system from Shanghai Zenith Machinery. Operating for over two years with an average output of 27 TPH, the system produces basalt powders used directly in the formulation of heavy drilling muds. The improved density control reduced drilling fluid loss by 18%, while the advanced automated control system decreased manpower requirements by 20%.
This real-world case highlights not only Zenith’s product reliability but also its ability to adapt designs according to the specific needs of the mining and energy industries.
For Australian companies involved in drilling operations, the efficiency and reliability of basalt powder production equipment directly impact drilling performance and cost control. Shanghai Zenith Machinery Co., Ltd. offers complete, field-proven grinding solutions that meet the demanding standards of 20–30 TPH basalt grinding for drilling mud. From the sophisticated MTW Trapezium Grinding Mill to the reliable LM Vertical Grinding Mill, each system demonstrates Zenith’s commitment to product innovation, energy optimization, and customer success.
As the demand for high-quality drilling materials continues to grow, partnering with a world-class equipment supplier like Zenith ensures continuous productivity, lower carbon footprints, and excellent return on investment.
