Asphalt batch mix plant is an equipment used in construction for manufacturing asphalt which is used mainly for road and other civil construction. Asphalt is made by blending together the appropriate quantity of aggregates, stone dust, and sand. This is then heated and a proportionate quantity of bitumen is allowed to be mixed at fixed temperature and then transported to the work site.
This machine is used to prepare hot mix asphalt in batches and so it is called a batching plant. It is available in different capacities of 80 tph, 120 tph, and 160 tph.
Some of the advantages of this plant are mentioned below:
- It is available in both being stationed and semi-mobile.
- Bag filter or wet dust collectors can be used for pollution control.
- The burner is multi-fuel as it can work on LDO/ diesel, FO. The burner of natural gas is also available.
- It has a twin shaft mixer with replaceable liners and is highly resistant.
- It has a PLC control panel. They also leave you with an option for SCADA panel.
The asphalt batch mix plant is divided into two units: 1) tower unit and 2) other components.
The section of tower unit mainly comprises of the vibrating screen, mixing unit, hot bins and optional storage silo.
Other components include cold feed bins, primary scalping screen, drying drum, weigh scales, control cabin, air compressor, bitumen tanks, bag filter and fuel tanks.
Description of the few components:
Vibrating screen: It has different chambers for separation of different aggregates so that they can be weighed and exact amount can be mixed.
Hot bins: these aggregates are stored in a separate compartment for a short time. This chamber lies below the vibrating screen. They are called hot bins. They hold these aggregates until they are weighed.
Mixing unit: The mixing unit mixes the aggregates, bitumen and additives to produce quality hot asphalt mix. It is fully jacketed unit.
Storage silos: The hot mix is then stored into theses storage silos temporarily.
Cold feed bins: The aggregates are put in this cold feed bins and then into the drying drum. They are of different sizes.
Primary scalping screen: Here the oversized particles are removed before it enters the drum.
Drying drum: The drying drum has a burner which heats the aggregates and removes moisture from it.
The asphalt batch mix plant manufacturers have noticed growing enquiries and orders for the equipment. Hence they are trying to leverage the sales by providing products with competitive rates and technical attributes.
The demand for asphalt batch mix plant is showing a rising trend. The rise in the demand is because the ambitious road development programme of 50000 km of the National Highway authority of India. The department of the public works also insists on the usage of asphalt plant.
The asphalt batch mix plant manufacturers are looking forward to meet this growing demand. This is undertaken by placing the products with economical technical properties, which means they manufacture plants consuming less fuel, easily mobile and using recycled materials.
Nowadays, it is becoming mandatory in many states to make use of asphalt batch mix plant where the work exceeds a certain value. So demand in this section will be on an upswing for about 5 – 6 years.
The asphalt batch mix plant manufacturers provide well trained personnel with appropriate stock of the parts to meet its requirements on demand. They manufacture plants that have advance programme logic which makes it operator friendly. The plant can be easily installed and dismantled within two to three days.
To stay in pace with this competitive world of technology the asphalt batch mix plant manufacturers have introduced this ‘counter flow technology’ which is a completely unique development that efficient, highly productive and eco- friendly.
Above all this with the growing demand the asphalt batch mix plant manufacturers are facing the problem of late delivery of the product. This is due to the production capacity limitations and gaps in backward integration on materials and production sourcing part.
As the asphalt batch mix plant manufacturers are on their way, introducing advanced technologies based on the requirements, these advancements need to be incorporated in the usage of RAP (recycled asphalt pavement material). As it is in an early stage, there are positive signs stating that the usage may increase as developers are looking to lower the cost and bring asphalt batching.
