Aggregates are the most mined materials in the world, and high throughput is vital to stay competitive. We are the preferred partner for aggregates operations all over the world, offering equipment for feeding, crushing, screening, washing, dewatering and thermal processing.
More than a century of experience across mining and adjacent industries, transformed into value for aggregates customers.
From primary crushing to final dewatering — covering the key processing stages of your aggregates operation.
Wash plants, sand plants and frac sand operations — each with specific process requirements that our equipment is designed to meet.
Spare parts, field service, upgrades and digital monitoring — keeping your operation running at peak efficiency.
We focus on mined aggregates such as sand, gravel and stone. Whether your operation is dry, wet or a combination, we have equipment and expertise to match.
In aggregates operations focused on sand and gravel, washing or wet processing is required to obtain the highest level of output quality.
As with our dry processing products, we utilise achievements from other industries to provide premium solutions in the wet stage. Proven solutions in this area include slurry pumps, hydrocyclones, knife gate valves, filters and filter presses, screens, attrition scrubbers, clarifiers and thickeners.
Water recovery and responsible discharge are increasingly critical in wash plant operations. Our thickeners and clarifiers support both product quality and environmental compliance.
In an aggregate plant, cyclones are most commonly used to recover saleable sand from a waste stream. Recovering sand from the classifier or sand screw overflow stream can add a significant amount of otherwise wasted material to the product.
In a typical sand recovery system, the sand screw overflow reports to a sump. A pump feeds the overflow to an elastomer-lined cyclone. The cyclone underflow contains the sand — it can be returned to the sand screw about three-quarters of the way up the screw, or stacked as a fine sand product. The cyclone overflow typically reports to the waste pond
Specialty sand, including frac, production requires tighter tolerances than standard aggregate processing. API specifications govern particle size distribution, crush resistance and turbidity — all of which depend on precise classification, thorough washing and effective drying.
The process typically involves scrubbing (to remove silica coatings), precise wet classification, dewatering and thermal drying to achieve the moisture content required for transport and use. Each stage demands equipment that can maintain consistency at high throughput.
Dry processing makes up the core of all aggregates operations. In operations focused on sand and gravel, washing or wet processing is added to obtain the highest level of output quality. FLS equipment covers feeding through to final dewatering and drying.
Feeders control the rate and flow of raw material into the crushing circuit, protecting downstream equipment and ensuring consistent throughput.
