ABSTRACT:
A storage silo system and an asphalt plant having the storage silo system, each including a silo bin, an input monitor arrangement for dynamically monitoring the mass of a flowable dry material being introduced into the silo bin, and an out monitor arrangement for dynamically monitoring the mass of the material being dispensed from the silo bin. The system includes a control unit which, in conjunction with the input and output monitor arrangements, dynamically monitors and controls the mass of the material contained in the silo bin. The input and output monitor arrangements each include a gravimetric weigh device having an enclosed, flexible wall belt scales and a clean-out auger for removing material that has fallen from the belt within the enclosure. The system may include an input bypass arrangement for adding additional portions of the material to the bin and an output bypass arrangement for removing additional portions of the material from the bin. An asphalt plant having the storage silo system is enabled to compensate for differences between rate of generation of mineral fill "dust" and demand rate for the "dust" for producing asphalt products.
