Morocco is an important barite producer in Africa, with mining areas mainly concentrated in the Djurdjura region of the Middle Atlas Mountains. The raw ore has high BaSO4 content, good whiteness, and low iron content, making it a high-quality raw material for producing coating-grade ultra-fine powder. However, Morocco's local processing capacity is weak, with most mining enterprises only engaged in raw ore mining and simple crushing and screening. High-value-added coating-grade and plastic-grade ultra-fine powder is almost entirely imported from China, Spain, and Italy, resulting in huge foreign exchange expenditure.
With the rapid development of Morocco's construction industry and automotive manufacturing industry, the demand for high-quality barite fillers from local coating, paint, and plastic industries has been increasing year by year. A large local mining group decided to extend its industrial chain and invest in building a coating-grade ultra-fine barite powder deep processing production line. After technical and economic comparison of various process routes including ball mill, jet mill, and ring-roller mill, it finally selected the ultra-fine ring-roller mill process with moderate investment, low energy consumption, and narrow finished product particle size distribution, building a 60,000 TPY coating-grade barite powder production line, aiming to replace imports, meet local demand, and export to the European market.
Based on the characteristics of Morocco's barite with high whiteness and low iron content, as well as the strict requirements of coating-grade products for whiteness, fineness, and oil absorption, the core equipment is configured as follows:
Single-cylinder hydraulic cone crusher, for medium-fine crushing of medium-high hardness barite ore, crushing 0-35mm raw ore to 5-10mm, with good product particle shape and low iron pollution, conducive to ensuring finished product whiteness.
Combination of bucket elevator and enclosed belt conveyor, fully enclosed conveying throughout, no material spillage, no dust overflow, adapted to outdoor and open factory production environments.
Multi-roller ring-roller mill structure, high grinding efficiency, fine finished product particle size, can stably produce 400-800 mesh ultra-fine powder, up to 1250 mesh. Grinding rollers and rings adopt special wear-resistant alloy, with low iron precipitation, ensuring finished product whiteness.
Supports stepless precise adjustment of fineness from 80 to 400 mesh, thorough separation of coarse and fine powder, ensuring 400-800 mesh drilling-grade powder batch uniformity and pass rate up to standard.
Negative pressure dust collection design, dust collection rate up to 99.9%, dust-free and pollution-free workshop, meeting local environmental production regulations, achieving green production.
Finished product storage bin caches materials, paired with fully automatic valve port packaging machine, automatic weighing, sealing, and packaging, adapted to large-volume storage and sea freight export needs.
Integrated fully automatic control system, one-key start-stop, automatic fault warning, overload protection, simple operation, adapted to overseas personnel operating habits, one person can monitor the entire production line.
The project adopts an industry-proven fully dry closed-circuit grinding process, requiring no water throughout, zero wastewater discharge, no secondary pollution, with simple process, strong stability, and low operation and maintenance costs, very suitable for overseas mining area production scenarios. The specific process is as follows:
Barite ore mined in the Djurdjura mining area is fed into the HPT hydraulic cone crusher by loader, crushed into uniform small pieces of material, meeting the grinding mill feed standard.
Qualified materials are sent into the grinding main unit grinding chamber through enclosed elevator and conveyor, and ground into powder under high-pressure rolling by grinding rollers and rings.
The ground powder enters the high-precision classifier with the airflow. Qualified 400-800 mesh powder enters the powder collector, while unqualified coarse powder automatically falls back to the grinding chamber for secondary grinding, zero material waste.
Trace dust generated during production is uniformly collected into the bag dust collector, clean air is discharged up to standard, and recovered dust can be reused, green and environmentally friendly.
Qualified coating-grade barite powder enters the finished product bin for caching, and is packaged and warehoused by the fully automatic packaging machine, ready for direct local supply or sea freight export.
Customized equipment solution based on Morocco's barite ore quality, climate, and factory working conditions, wear-resistant and durable, strong adaptability, perfectly adapted to the extensive production environment of overseas mining areas, with extremely low equipment failure rate.
Finished product specific gravity, fineness, and purity fully meet international oilfield drilling fluid material specifications, can replace imported powder, successfully opening the West African overseas oilfield market.
Annual output of 80,000 tons stable capacity, 24-hour continuous production, capacity increased by more than 60% compared to traditional equipment, greatly improving enterprise supply capacity and market competitiveness.
Fully enclosed production + efficient dust collection system, no dust, no wastewater, low noise, meeting local environmental policies, enabling long-term compliant production.
Fully automatic intelligent operation, no need for professional technicians, one person can monitor, adapted to the current situation of overseas labor shortage and weak technical capabilities.
Fineness can be freely adjusted, in addition to drilling-grade powder, can also produce coating and filler grade barite powder, multi-category operation, broadening profit channels.
Yes. The complete line is specially engineered for natural barite ore with varying impurity levels and hardness. The jaw crusher, Raymond mill host, and high-precision classifier work together to process barite from different mining regions, delivering consistent 200-325 mesh drilling-grade powder with stable specific gravity and purity.
200-325 mesh is the internationally accepted fineness range for oil and gas drilling fluid weighting agents. It ensures proper suspension, rheology, and wellbore stability. The line supports stepless adjustment from 80 to 400 mesh, allowing customers to switch between drilling-grade, coating-grade, and filler-grade products for diversified revenue.
Absolutely. The fully dry closed-circuit process requires no water and produces zero wastewater, making it ideal for high-temperature, water-scarce regions in Africa. The equipment is designed for continuous outdoor operation under harsh climatic conditions with stable performance year-round.
The line features a simple structure, few wearing parts, and extended service life thanks to high-chromium alloy rollers and rings. Routine maintenance only requires basic cleaning, lubrication, and wear-part inspection. The manufacturer provides remote technical guidance and overseas after-sales support to resolve issues quickly.
Yes. Every project is tailored to the customer's site dimensions, investment budget, and capacity requirements. The equipment configuration and plant layout are optimized to fit small to large factory areas, ensuring maximum space utilization and ROI for overseas mining operations.
Yes. The finished powder meets API and international oilfield specifications for specific gravity, fineness, and purity.
