1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your sand and gravel pit’s profitability? For professional producers, key challenges directly impact the bottom line. Inefficient material classification leads to product outside spec, forcing costly reprocessing or degrading saleable yield. Frequent screen media replacement and associated downtime for changes halt your entire processing line. Inconsistent feed rates and blinding from highmoisture material reduce effective screening capacity, creating bottlenecks. The constant vibration and abrasive wear on machine components result in premature failures and high maintenance labor costs.

How do you increase throughput of inspec material while controlling the total cost of ownership? What if your primary screening solution could deliver greater availability, adapt to variable feed conditions, and extend component life? The answer lies in selecting a highperformance vibrating screen engineered for the demands of modern aggregate production.

2. PRODUCT OVERVIEW: HEAVYDUTY VIBRATING SCREEN

This heavyduty vibrating screen is a linear motion screening machine designed for highcapacity sizing and scalping of sand, gravel, crushed stone, and recycled aggregates. It serves as the critical primary separation point in your plant’s workflow.

Operational Workflow:
1. Feed: Raw, unsized feed material is delivered via conveyor onto the screen’s robust feed box.
2. Separation: The dualvibrator mechanism generates a linear throwing motion, conveying material along the deck while stratifying it. Smaller particles pass through the screen media apertures; oversize material travels to the discharge end.
3. Discharge: Correctly sized product (undersize) collects in a hopper beneath the deck, while oversize is discharged for further crushing or stockpiling.

Application Scope: Ideal for primary sizing (scalping) ahead of crushers, final product sizing (e.g., separating sand from gravel), and drainandrinse applications. It is suited for stationary plants and large portable setups.

Limitations: Not designed for fine separation below 3mm (typically handled by washing screens or cyclones) or for sticky, claybound material without specialized screen media solutions.
