An asphalt plant is referred to as a plant utilized for manufacturing asphalt, macadam, and additional forms of coated roadstone, sometimes jointly known as blacktop or asphalt concrete. The main purpose of an Asphalt plant is to merge aggregates, asphalt, and additional additives in necessary proportion according to the job mix formula and at high temperature to create a uniform hot mix paving mixture. The hot mix asphalt is helpful for the construction of the road. 

There are commonly two types of Asphalt plants:

 

  • Batch Mix Plant (Discontinuous type):

Here, the heating and drying plant of aggregates takes place in the rotary drum and heated aggregates are calculated and weighed in hot bins for proportioning before merging in the different pugmill kinds to create one batch.

 

  • Drum Mix Plant. (Continuous type)

On the other hand, here the heating, drying, and blending combined with the binder takes in the similar drum were in the feeding of aggregates and binders. The output of the hot mix asphalt is permanent. They promise higher rates of production and are simple to operate. As compared to batch-type plants, it is a cheap and cost-effective choice. Despite the kind of Asphalt Mixing Plant, the prime role is the same to create the quality hot mix asphalt to be used during the construction of the road. 

 

The essential elements of Asphalt Drum Mix Plants are Multiple Cold Aggregate Feeder Bins, Rotary Drum, Burner, Single Deck Scalping Screen, Slinger Conveyor, Load out Conveyor, Asphalt Tank, Wet Scrubber, Mineral Filler Unit, Fuel Service Tank, and Control Panel with Insulated Control Cabin. According to the choice of the customers, the plants can be portable or stand at the place. 

 

Continuous mixing plants

Counterflow asphalt mixing plant and asphalt drum mix plant are two special kinds of plants that are grouped as continuous mixing plants. Both kinds of plants produce hot mix asphalt in a regular procedure. Batch mix plants are available to create hot mix asphalt in batch. The final product is to find hot mix asphalt but the development of batching plants and constant plants is completely different from each other. The difference in the procedure is what makes the quality of hot mix asphalt special in different kinds of plants. 

 

Asphalt drum mix plant process 

The process begins with the feeding of cold aggregates direct into feed bins. The tools are commonly equipped with three or more feeders and aggregates are loaded into diverse bins according to the needs of the sizes. It can be completed as different sized aggregates can be graded according to the needs. Each bin is offered with divided adaptable gates for controlling the material flow. There is a long conveyor belt below the bins that takes the collectives to the scalping monitor.

 

The charging conveyor plays a significant role in the asphalt plant procedure as it does not just change the cold aggregates from below the drum screen but also does the weighing of the aggregates. The conveyor is prepared with a load cell that endlessly weighs the aggregates and sends a sign to the control panel.

 

The drying and mixing drum is accountable for two operations: first drying and then mixing. This drum is endlessly rotating and in the rotation course, aggregates are changed from one end to the other. The aggregates are handled to heat by the burner flame to decrease the content of the moisture in the aggregates.

The next walk-in driveway cleaning is to close the asphalt driveway with an appropriate sealer. For finding the best results it is sensible to apply two thin coats of a sealer despite the single thick coat. Begin from one end of the driveway and vocation your way to the other end. Begin applying the first coat of sealer in one way and then oppositely apply the second coat. To apply the sealer on the border of the driveway it is improved to use a paintbrush.

 

Asphalt Plants in India are available for the companies who are looking for them. Pollution control devices play a significant role in the process. They assist to remove the harmful gases that may have run away from the environment. The collector of the primary dust is a dry dust collector. It works in sync with a secondary dust collector which can be a bag filter or a scrubber of wet dust.

 

Conclusion:

No matter how tough and challenging the job may be, if you select the appropriate kind of equipment from the right manufacturer you will be astonished by the results that you selected machine delivers.
