Iron ore dressing plant
Handling abrasive fluids can be tough for many industries, especially in mining. Traditional valves, like stainless steel and iron cast valves, often wear out quickly, leading to high maintenance costs. In this case our Ramén Ball Sector Valve KSG proved that soft natural rubber in certain cases is much more resistant than steel.
Challenge
Previous valve technologies, such as pinch valves, failed to meet the demands of the harsh mining environment.
Solution
A Ramén KSG rubber-lined Ball Sector Valve was installed to improve performance.
Result
After two years, the valve remained was still in very good condition, demonstrating its durability and replacing other technologies.
Application: Throttling control of water to magnetic separator where iron is separated from granite in iron ore dressing plants
Flow: 90 m3/h with 12-15 g solids/liter
Inlet pressure: 2 bar
Pressure drop: 2 bar
Background
At one of Sweden’s largest iron mines, the operations demanded robust and reliable valve solutions due to the harsh conditions involved in handling abrasive materials.
Challenge
The mine previously experienced issues with valve technologies like pinch valves, which struggled to maintain performance and durability under the severe service conditions.
Measures and results
A Ramén KSG rubber lined Ball Sector Valve was installed. Two years later the valve was taken out of service. The rubber was beginning to come loose from the sector but the valve was still in very good condition. This established the KSG valve design as the preferred valve technology in severe services and replaced other valve technologies such as pinch valves.
