This customer has abundant barite reserves. Before knowing MR, they already used a Raymond mill, but it frequently broke down, causing production interruptions. MR helped the customer analyze the causes of these issues and provided reliable solutions, leading them to purchase a new barite grinding line with a capacity of 12 tons per hour.
Raw Material: Barite
Feed Size: 200mm
Output Size: 200 Mesh
Production Capacity: 12 t/h
Passing Rate: 98%
Mill Model: MGW138
Location: Latin America
Before purchasing our Raymond mill, the customer operated equipment from other brands, facing recurring issues that affected their productivity.
The pipe connecting the cyclone to the main unit of the mill kept getting punctured, causing material leakage.
Barite has a density of 4.5 g/cm³ and a Mohs hardness of 3 to 3.5. Among non-metallic minerals, it has high abrasiveness.
We reinforced the pipes with an internal lining of wear-resistant ceramic plates. This additional shielding significantly increases the service life of the ducts, withstanding the continuous impact of barite dust.
The fan frequently got clogged, stopping the airflow and production.
The project is located at 2,500 meters above sea level (masl). At high altitudes, the lower air density affects pneumatic performance.
We redesigned the ventilation system by installing a higher-capacity fan, with increased pressure and air volume. Additionally, we equipped the system with special motors for high altitude, ensuring stable operation without blockages in mountain conditions.
