Modern Quarrying Q1 2023

Global demand for aggregates and mining materials is on the rise with the industry facing an expected growth of nearly 4,2 billion tons over the next 15 years. That’s a lot of material, which means producers need efficient equipment to meet spec and turn a meaningful profit. By Duncan High, Haver & Boecker Niagara Processing Equipment Technology Manager THE ROAD LESS TRAVELLED CAN OFFER GREATER SCREENING PRODUCTIVITY

CRUSHING AND SCREENING

KEY TAKEAWAYS

Every ton of material must go over at least one vibrating screen, so ensuring the equipment’s efficiency is critical to an operation’s success.

Vibrating screens that are engineered with a double eccentric shaft assembly create a constant stroke to maintain g-force during material surging.

E very ton of material must go over at least one vibrating screen, so ensuring the equipment’s efficiency is critical to an operation’s success. The good news is that there are technologies available today that can help increase or improve screening productivity. Integrating cutting edge systems like eccentric screening technology, state of-the-art screen media and diagnostic tools can prevent blinding, pegging, carry-over Duncan High is the Processing Equipment Technology Manager at Haver & Boecker Niagara.

By incorporating impact testing into an operation’s regular maintenance routine, producers can ensure optimum screening performance and equipment reliability.

The development of the double eccentric screen and other screening technology provides operations with innovative and cost-effective ways to increase their profits and efficiency.
