Asphalt Plant Manufacturer and Asphalt Drum Mix Plant by iupon13


									?Infrastructure is defined as the basic physical and organizational structures needed
for the operation of a nation. It includes the technical structures that support a society,
such as roads, water supply, sewers, power grids, telecommunications, etc. When we
view it functionally, infrastructure facilitates the production of goods and services.
The term also includes basic social services such as schools and hospitals.

Asphalt is considered to be the best road building material. It binds well and is also

An asphalt plant is a plant used for the manufacture of asphalt, macadam and other
forms of coated road stone, sometimes collectively known as blacktop. Asphalt plants
are of two types: drum mix plant and batch mix plants.

Asphalt Plants are primarily divided into two types: Continuous Mixing Type (Drum
Mix Plants) and Batch type asphalt plants.

Drum mix plant is a continuous mixing plant. The asphalt continuous mixing plant
system consists of a total proportional controlled cold feed system, which delivers
material on a slinger (charging) conveyor. From the other end, the asphalt and filler
proportion enters the drum simultaneously with aggregate.

The main component of asphalt drum mix plant is a parallel flow drum mixer which is
a large rotating cylinder. The main gearbox drives the drum by a half chain to a large
sprocket bolted to the outside of the drum.

As the aggregate gets inside the drum from the slinger conveyor, on the other end
bitumen and lime is introduced. The bitumen cools very fast and as a result jells up
with the fine aggregates and dust.

In the asphalt mixing continuous plant, raw aggregate is fed into the cold aggregate
feeders and specific quantity is delivered to the drum where initially drying and then
mixing with bitumen takes place. The temperature inside the drier drum is around
150-180 degree Celsius. The finished product is almost invariably discharged into a
hot store rather than directly into delivery vehicles.

Hot storage SILOS can also be used with the plant to store the mix material when
needed. Pollution control devices like the venture type dust collector device and even
bag house can be fitted with the plant.
