1. PORTABLE HOPPERS

RD portable hoppers and bins are available with or without variable-incline belt feed conveyors and variable-rate vibratory pan feeders and are designed to handle a variety of bulk materials in mining, construction, demolition, aggregate, and concrete recycling applications. Feed hoppers handle materials at rates of 300 to 1000 tons per hour and can be used for everything from loading trucks, barges, and rail cars to feeding crushers and screen plants. Typically, bins and hoppers are mounted on a wide flange beam chassis with truck axles, air brakes, and signal lights for highway towing RD engineers will customize designs to meet individual customer needs.

2. STATIONARY HOPPERS AND BINS

RD will custom-design and build surge, storage, and blending bins or complete feed systems for virtually all kinds of bulk materials, such as: sand/gravel, aggregates, coal, coke, and slag. They can be designed from scratch or to meet your specifications for new or existing facilities and can be furnished with a variety of vibratory and belt feeders, or clam gate outlets. Typical applications are quarries, power plants, and steel mills. In quarries, surge bins are often used to temporarily store materials coming from the primary crusher and feed them at the proper rate into secondary and tertiary crushers. In other applications, the bins are used for longer-term, cumulative storage and as feed hoppers for railroad cars, trucks, boats, and barges. RD can integrate load cells into bins for weighing and batching systems.
