Asphalt Drum Mix Plant

Asphalt Drum Mix Plant

Infrastructure can be defined as the basic physical and organizational structures needed for the operation of a nation. The term typically refers to the technical structures that support a society, such as roads, water supply, sewers, power grids, telecommunications, etc. Viewed functionally, infrastructure facilitates the production of goods and services; for example, roads enable the transport of raw materials to a factory, and also for the distribution of finished products to markets. The term may also include basic social services such as schools and hospitals.

Infrastructure is the mirror of a nation. When we talk about building a nation, we need to have better communication and that each part should be connected to the entire nation. For this the entire structure of infrastructure has to be developed and each part has to be well connected.

Each nation has to be fast developing its infrastructure to meet the needs of future and to be well connected; roads have to be well developed. Asphalt is considered to be the best road building material. It binds well and is also durable.

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. Road building demands the combination of a number of aggregates, sand and a filler (such as stone dust), in the correct proportions, heated, and finally coated with a binder, usually bitumen based or, in some cases, tar.

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

In the 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 venturi type dust collector device and even bag house can be fitted with the plant.

The main advantages of this plant are:

Continuous mixing type plants are cheaper to own. Drum type asphalt plants are easier and faster to erect and install. Drum mix plants are low on maintenance. Asphalt drum mix plants are low on transport costs. Asphalt mixing plants are accurate with only +/- 2% variations. Drum type asphalt plants takes less space to fit.
