Asphalt Plant for Road Construction Industry
The purpose of an Asphalt Plant is to blend aggregates, asphalt and other additives in required proportion as per job mix formula and at elevated temperature to produce a homogeneous hot mix paving mixture. This hot mix asphalt is used for Road Construction . There are basically two types (based on design) of Plants (1) Batch Mix Plant (Discontinuous type) and (2) Drum Mix Plant. (Continuous type) In Batch type Plant, drying and heating of aggregates take place in rotary drum and heated aggregates are weighed & screened-in hot bins for proportioning prior to blending with a binder in separate pugmill type mixer to make up one batch. In Drum type Plant the heating, drying and blending of aggregates with the binder takes in the same drum wherein the feeding of aggregates & binders and output of hot mix asphalt is continuous. This type of plant gives a higher production rate and is easy & simple to operate. They are cheaper compared to the batch type plants. Regard...
