How does An Asphalt Plant Work

A Short Profile of an Asphalt Plant

An asphalt mixing plant, also referred to as asphalt concrete mixing plant or asphalt plant is the plant that is used to produce asphalt mixture. The asphalt mixture is that the aggregates (sand, stone) in different particle sizes, binders (asphalt or residual oil) and fillers (mineral powder) are mixed according to specified proportion. It can produce not only asphalt mixture, but also modified asphalt mixture and colored asphalt mixture.

The asphalt plant can be categorized into three types:

Based on the production technique, it is divided into:

The asphalt plant is the essential equipment of these construction projects such as motorways, classified highways, municipal service roads, jumbo airports, parking lots and coastal ports.

Working Process of An Asphalt Plant

How does an asphalt plant work or what is the working principle of an asphalt? It is explained as below:

The cold material in the cold bin is firstly transported to the dryer drum through the belt conveyor.

Secondly the dried aggregate is transported to the vibrating screen for screening by the hot material elevator, and the screened aggregate falls into each compartment of the hot material silo.

Then aggregate and powder fall into its own weighing bucket through the relative chamber door with being measured by an electronic scale. Next they are put into the mixing tank.

lastly, all mixtures are fully mixed, asphalt mixture is formed and unloaded to the hopper car. The feeding hopper car is unloaded into the mixed material storage bin through the track, and finally the mixed materials are placed on the transport vehicle through the unloading gate.
