Different sizes of aggregates stockpiling and feeding into bins.
Screening of aggregates. In continuous type the aggregates are screened to remove over size. While in batch type the aggregates are screened to separate them into different compartments.
Drying and heating of aggregates.
Melting storage and transfer of bitumen
Storage and transfer of filler material.
Bitumen, aggregates and filler material are weighed in batch type
plants. Where in continuous type
plants they are added and controlled by a variable frequency drive.
Discharge of hot mix asphalt into truck or a storage silo.
Control panel is common for both the types. It controls the activities of the
