Flow control for mineral processing and demanding slurry applications

Flow control for mineral processing and demanding slurry applications

Abrasive conditions in mineral processing require high performance and reliable process equipment. In Valmet’s Flowrox pinch valves and hose pumps, only wear-resistant rubber hoses come into contact with slurry, which guarantees long service intervals and easy maintenance. We have decades of experience in demanding slurry applications and have developed unique products that often outperform the standard products on the market.

Reliability

High performance

Durability

The performance of the process depends on the reliability of its components. What may at first seem like a low-cost flow control device can quickly result in high maintenance costs and plant downtime. In addition to the abrasive nature of mining slurry, plastic and metal wire waste that may occur in mineral processing can cause equipment clogging and poor process reliability. The full-bore feature of Flowrox pinch valves and positive displacement hose pumps ensures trouble-free operation, even in the most demanding and sometimes surprising conditions.

Applications

Valmet’s Flowrox pinch valves are market leaders in flotation cell level control and tower press filter applications, where continuous valve compressions have proven their superior performance.

Flowrox LPP-T hose pumps offer the longest hose life and pump service intervals in continuous operation compared to conventional hose pumps. Regular maintenance mainly includes the replacement of hoses, which is quick and simple in LPP-T hose pumps thanks to the patented hose connection. Wear is effectively limited to the elastomer sleeve or hose inside the pinch valves and hose pumps.

The design and development of Valmet’s innovative high-quality slurry valves and pumps have been based on decades of experience and close cooperation with our customers in mineral processing. Valmet’s flow control products and global service organization in more than 40 countries guarantee the reliability and performance of mining processes.

Flowrox™ flow control products have been very successful in various applications:

Flotation level control

Thickener underflow

High pressure filtration

Analyzer sample transfer

Storage tanks

Process pipelines
