As the product is transported by conveyor, vibration and motion of the belt causes fine particles to settle on the bottom. The resulting stockpile is segregated, with coarse particles settled at the toes, and fine particles in the center portion of the pile. Segregation of aggregate base can lead to rejection or costly penalties for the producer, and base material is especially susceptible to segregation because of a greater variation in particle size than that of other stockpiled products.
The formation of a continuous layered stockpile will reduce the effects of segregation and eliminate the need to re-blend the base before shipment. A radial or telescopic conveyor can be used to construct a layered stockpile. If this equipment is not available a dozer may substitute.
Using windrow stockpiler with radial telescopic stacker can help us solve this problems.
1. Minimize drop height to limit overrun (variable height conveyors).
2. Use telescoping conveyor and build in windrows.
3. Load from end of pile.
1. Build stockpile with fixed height conveyors.
2. Build stockpiles with trucks, loaders or dozers.
1. Easy pile to build.
2. Must have axle system to allow movement radially.
3. Feed point is stationary.
4. Simple way of increasing volume with the same feed point.
5. Increases live storage.
6. Most consistent product to load out.
