As industrial activities in Southeast Asia continue to expand, Laos has become an emerging market for high-grade mineral processing and drilling fluid solutions. One application that has drawn significant attention is the use of marble grinding mills in the production of drilling mud additives. In oil and gas drilling operations, marble-derived calcium carbonate provides essential rheological properties and enhances wellbore stability. To achieve optimal fineness and consistent quality, it is essential to select a grinding system that combines efficiency, precision, and durability.
Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of ore grinding equipment in China, offers advanced systems tailored for this purpose. With decades of expertise in ultra-fine powder processing, Zenith’s machines are engineered to handle a wide range of raw materials and deliver superior output for industrial applications, including the production of drilling-grade marble powder in the range of 10–20 tph.

Drilling mud, or drilling fluid, plays a critical role in oil and gas exploration. Among its multiple functions—cooling the drill bit, carrying cuttings to the surface, and maintaining hydrostatic pressure—its performance is often enhanced by additives such as calcium carbonate. Finely ground marble, essentially pure CaCO₃, provides excellent bridging and sealing properties in permeable formations, helping to prevent fluid loss and minimize formation damage.
Producing marble powder for drilling applications requires precise control over particle size distribution. Particles typically range between 5 to 150 microns, depending on drilling conditions. To achieve such fine control, advanced milling technologies—such as vertical and trapezium grinding mills—are used. These mills ensure the desired consistency while maintaining low energy consumption and operational stability.
The implementation of a marble grinding mill project in Laos, targeting 10–20 tons per hour, represents a strategic investment in the local mining and oilfield industries. The availability of high-purity marble deposits in central and southern Laos makes it an ideal opportunity to produce drilling mud additives locally rather than importing them. However, key challenges include selecting appropriate grinding equipment that can process variable feed sizes and hardness while meeting strict product quality and environmental standards.

Shanghai Zenith Machinery Co., Ltd. provides a comprehensive line of grinding equipment designed for diverse industrial applications. For this particular project, two recommended choices stand out for 10–20 tph marble powder production—the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill. These models are well proven in powder processing for minerals like limestone, marble, dolomite, and barite, which are commonly used as drilling fluid materials.
The MTW Trapezium Grinding Mill is renowned for its durability, high efficiency, and precision classification. It incorporates advanced European technology to achieve smooth operation and stable particle size control. The integrated design, featuring bevel gear drive and thin oil lubrication, ensures long life and low maintenance. For marble grinding in Laos, MTW138Z or MTW175G models provide an ideal combination of capacity and energy efficiency.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
The MTW series is particularly advantageous in energy-saving performance and operational ease. The adjustable grinding rollers and classifier system make it possible to achieve target fineness between 45–38 microns, perfectly suited for drilling mud filler materials.
As an alternative, the LM Vertical Grinding Mill offers an integrated solution with functions of crushing, drying, grinding, and classification in one unit. This vertical configuration provides a compact plant layout, which is beneficial for limited-space installations in Laos. Its high drying capacity suits local marble materials that may contain moisture due to tropical humidity.
| 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 |
LM Vertical Grinding Mills are also known for their low vibration, reduced noise, and clean production process, which complies with international environmental standards. When configured with automatic control and dust collection systems, they provide an efficient and safe solution for continuous marble processing in industrial environments.

For drilling mud producers in Laos, adopting Zenith’s milling technology results in multiple operational benefits:
In trial operation projects across Southeast Asia, including similar installations in Vietnam and Thailand, Zenith’s marble grinding systems have consistently achieved D97 values below 45 microns with stable throughput. When applied to the Laos 10–20 tph drilling mud facility, the resulting marble powder will exhibit high purity and optimal rheological performance when dispersed in drilling fluids. Enhanced wellbore integrity and lower fluid loss translate into improved efficiency and reduced operational costs for drilling contractors.
Shanghai Zenith Machinery Co., Ltd., with years of extensive experience in grinding technology and comprehensive customer support, provides solutions that go beyond equipment supply. From project engineering, installation, and commissioning to operator training, Zenith ensures smooth project delivery and reliable long-term performance.
Its global footprint, including projects across Asia, Africa, and the Middle East, reinforces its reputation as a trusted partner in industrial powder processing.
