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 plant and gives us report of
the important parameters.
