Mine Boosts Trommel Efficiency with Spraying Systems Co. Self-Aligning Spray Nozzles

Problem

In gold mining operations, trommels play a key role in separating smaller, gold-bearing material from larger rocks and debris. However, one of the world’s leading gold producers — was facing reduced efficiency due to inconsistent washing and cleaning performance in their trommels. They needed a reliable spray nozzle solution to improve throughput and cleaning consistency.

Solution

To enhance performance, they partnered with Spraying Systems Co. to install two precision-engineered spray bars. One bar sprays water directly onto the ore for washing, while the second is dedicated to cleaning the trommel screen.

Each spray bar is equipped with Spraying Systems Co. self-aligning flat fan spray nozzles — ideal for heavy-duty cleaning in mining and processing environments. These nozzles feature a grooved body design that ensures accurate, repeatable alignment without requiring elastomeric seals. The interchangeable self-aligning spray tips slide easily into place, maintaining exact positioning and spray pattern after every reassembly or nozzle replacement.

This innovation keeps the original spray angle, overlap, and flow efficiency intact — ensuring long-term reliability and consistent trommel performance.

Results – Spray System

By using self-aligning spray nozzles from Spraying Systems Co., the mine achieved a major improvement in trommel cleaning consistency and ore washing effectiveness. The dedicated spray bars eliminate the risk of incorrect nozzle orientation during maintenance — once worn tips are replaced, they automatically align perfectly for precise, repeatable performance.

The result is greater operational efficiency, reduced downtime, and improved productivity across Newcrest’s gold processing operations.
