Metals & Foundry

The steel industry includes a wide range of processes that handle sand and silica sand for casting of metals, additives such as coke, and waste products such as EAF dust in baghouses and electrostatic precipitators (ESP) dust applications.

Our first conveying systems in the US were installed in foundries—highly dusty environments handling abrasive materials. It was a perfect match; our completely enclosed technology conveys abrasive sand and silica sand at very low velocities, controlling dust, reducing pipe wear, and lowering maintenance and energy costs.  Foundries remain our largest group of customers, with many systems operating reliably for over 30 years. The adaptability of our designs also makes retrofitting an efficient solution for existing operations, requiring minimal layout modifications.

A cornerstone of this success is our Sandpump®, a dense phase pneumatic system designed specifically for sand handling in foundries and metal casting applications. Its low-profile design and top-side discharge allow for easy integration into existing systems, making it particularly well-suited for retrofit projects and packaged casting operations. Operating at very low velocities, the Sandpump® minimizes wear and maintenance while ensuring consistent and reliable sand transfer. Thousands of Sandpump® systems are installed worldwide, demonstrating their proven performance in demanding foundry environments.

Separately, our Macawber Ashveyors® are widely used in the US steel industry to convey EAF dust and other dense bulk materials. Ashveyors® are dense phase systems engineered to handle high bulk density dusts without wear, making them ideal for smelt processes, baghouses, and dust collection systems. Many steel producers have standardized on Ashveyors® for their smelter operations due to their reliability and low maintenance requirements.

Our experience also includes dust handling systems for baghouses, electrostatic precipitators, carbon injection systems, and injection systems handling lead concentrate. Together, Sandpump® and Ashveyor® technologies provide tailored solutions for conveying abrasive or challenging materials throughout metals and foundry operations, helping provide a safe, breathable environment with reduced silica airborne hazards.
