• Supported by the AASPA Minerals global service network
1. The Warman centrifugal slurry pump, pumps the slurry from the sump to the Cavex hydrocyclone at the top of the plant. The Cavex hydrocyclone separates fine from coarse particles.
2. Finer particles are discharged at the top of the hydrocyclone which are then passed to an overflow box at the side of the hydrocyclone and is then fed to the effluent treatment via hoses and pipes.
3. Coarse particles are fed to the Enduron dewatering screen through the underflow of the hydrocyclone. The Enduron dewatering screen removes the water and residual fines from the product. The Enduron screen also features spray bars if further cleaning of the material is required.
4. Water and residual fine material are discharged through the screen media and passed into the sump.
5. Saleable sand is discharged at the front of the screen through chutes where it is stockpiled ready for sale. Linatex premium rubber is used to protect areas of high wear throughout the entire plant.
Cavex hydrocyclones
Cavex hydrocyclones use a proven design to separate material while delivering maximum efficiency, capacity and a long wear life. The laminar spiral inlet geometry of a Cavex hydrocyclone is fundamental to increasing productivity while lowering total ownership costs. By minimising flow resistance through the feed chamber, Cavex hydrocyclones can process substantially higher volumes of sand than conventional Hydrocyclones. Cavex hydrocyclones also feature a cut point perfectly suited to sand wash applications.
Enduron dewatering screens
Enduron dewatering screens are proven performers in sand washing applications. Effective in reducing moisture content in sand products, these screens also offer exceptionally high throughput per unit screening area. These linear motion screens feature a lock-bolted frame with epoxy adhesive applied between all mating surfaces, adding a layer of moisture and corrosion protection. Modular screen deck panels deliver long life and easy handling and maintenance, making it simple to replace areas of localised wear. Moulded rubber buffers are used on all four support points to isolate live frame vibrating loads. Enduron dewatering screens are lined with Linatex premium rubber and offer excellent water removal and high load capacity, while lowering total cost of ownership.
Warman WGR Gen 2 slurry pump
AASPAMinerals has specifically designed an engineered the Warman WGR pump for sand and aggregate applications. This pump offers several innovative features including improved hydraulic design, enhanced gland options and a simplified wet-end. In addition, it also delivers added features for improved safety and reduced maintenance such as a drainage plug situated on the casing (which can be pulled in cold months so that the pump does not freeze or clog when stopped).
Linatex hose and rubber lining
Linatex premium rubber is a 95% natural rubber that exhibits outstanding resilience, strength and resistance to cutting, tearing and abrasion. With over 90 years of handling aggressive materials in quarries across the globe, Linatex is still ranked as the premium wear resistant rubber for protecting processing equipment in wet or highly abrasive applications. It is the unique liquid phase compounding process that gives Linatex premium rubber its extraordinary physical properties and outstanding performance. This unique process causes minimal mechanical disturbance to the molecular structure of the finished rubber, resulting in significant cost benefits for customers. With Linatex premium rubber, there is no equivalent when it comes to wet abrasion.
