Project Experience
Selected Mineral Powder Processing Cases
Real project experience helps us understand how different drilling minerals behave in industrial grinding systems.
LM Vertical Roller Mill
30 TPH Bentonite Grinding Plant — Indonesia
This bentonite grinding project uses an LM22-2K Vertical Mill for continuous industrial powder production. The published project configuration delivers 30 tph of bentonite at 150–200 mesh.
The case is listed in Liming Heavy Industry's bentonite grinding portfolio. Final equipment selection for a new project should be based on actual material properties and product requirements.
MTW European Grinding Mill
Barite Powder Production Project — China
This barite project uses the MTW European Trapezium Grinding Mill as the core grinding equipment. The process integrates crushing, grinding, classification and conveying in a closed-loop configuration for controlled barite powder production.
The project experience demonstrates MTW's application in barite powder processing. Product specifications should be confirmed according to the intended drilling-fluid application.

Drilling Mineral Powder Processing FAQ
What minerals are commonly processed for oil and gas drilling?
Barite is the primary mineral associated with drilling-fluid weighting. Bentonite is widely used in drilling-fluid systems, while calcium carbonate and other minerals may be selected for specific formulation requirements.
What grinding mill is suitable for barite processing?
The suitable mill depends on the required capacity, feed size, target fineness, material properties and plant configuration. Liming Heavy Industry can evaluate the project and recommend an LM or MTW-based solution.
Can the LM Vertical Roller Mill process drilling minerals?
Yes. The LM Vertical Roller Mill can be configured for industrial processing of suitable non-metallic minerals such as barite, limestone and calcium carbonate, subject to material and process requirements.
Can the MTW European Grinding Mill process barite and calcium carbonate?
Yes. MTW is designed for efficient processing of many non-metallic minerals and can be considered for barite, calcium carbonate and related mineral powder applications.
Can bentonite be included in a mineral powder processing project?
Bentonite can be processed in suitable grinding systems, but its moisture, clay characteristics, feed condition and required product properties should be evaluated before final equipment selection.
What determines the required powder fineness?
The target particle-size distribution depends on the drilling-fluid formulation, application, product specification and downstream use. The grinding and classification system should therefore be designed around the customer's actual product requirement.
Can the plant include crushing, grinding, classification and dust collection?
Yes. A complete configuration can combine material preparation, grinding, classification, dust collection, conveying, storage and packing according to the project scope.
How do I choose between LM and MTW?
LM is generally positioned for larger-scale industrial production and integrated process layouts, while MTW provides a flexible option for efficient mineral powder production. The final choice should be based on capacity, material properties, fineness and plant requirements.
