◊ After screening the aggregates, they are stored in hot material bins. The stored aggregates are later proportioned to produce the bituminous mixture.
◊ The finest material is separated first into a bin by a vibrating screen; oversize material is caught by a scalping screen and discharged from the tower. Other material sizes are separated by vibrating screens and stored in the remaining bins.
◊ The control system then proportions the hot aggregates from the bins into the weigh box which is mounted on a set of scales.
◊ These dry aggregates are discharged into the pugmill and the hot bitumen, which has been weighed and stored in a weigh bucket, is sprayed into the pugmill after a few seconds of dry mixing.
