Grasan portable hoppers and bins are available with our without variable-incline belt feed conveyors and variable-rate vibratory pan feeders. Hoppers and bins are designed to handle a variety of bulk materials in construction, demolition, aggregate and concrete recycling and mining applications. Feed hoppers handle materials at rates of 300 to 1,000 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. Grasan engineers will customize designs to meet individual customer needs.
