There are two types of asphalt mixing plants: batch-type continuous plant and drum-type continuous plant. The latter is more famous because of the wide range of features that it provides to construction companies. It mixes asphalt, dry warm aggregate, and padding to produce coated road stones.
If you are looking to buy a drum mixing asphalt plant for your construction company, here are some of the features that it should have:
• Half chain drive that offers trouble-free operation and less vibration.
• An SS sheet drying drum covering and 1260o C resistant coated cerawool that provides maximum heat retention.
• Long-lasting and robust body.
• Burner with different types of fuel options.
• Wet and dry dust collector to reduce the amount of water and air pollution.
• Fully covered bitumen tanks that offer maximum heat retention.
• Maintenance-free design.
• Advanced PLC control panel.
Parts of a drum mixing asphalt plant
Some of the parts that a drum hot mix asphalt plant contains are as follows:
1. Cold feed bins – These bins collect all the aggregates that need to go into the drying drum. Each bin has adjustable gates that allow different ingredients to flow easily.
2. Single deck vibrating screen – This screen separates various oversized aggregates and prevents them from going into the drying drum.
3. Weighing conveyor – The weighing conveyor is responsible for transferring the aggregates into the drum from the cold feed bins. This conveyor has aggregates that pass through a belt before reaching the drum.
4. Drying and mixing drum – The rotating drum contains flights that dry up the aggregates and ensure that they mix with the bitumen properly.
5. Fuel tank – The fuel tank houses the drum burner and supplies fuel whenever required.
6. Asphalt storage tank – Most drum mixing plants have multiple storage tanks that collect hot aggregates and supply them to the drum whenever required.
7. Filler silo – The filler silo contains binding material that the bitumen mixing plant adds to the mixture slowly.
8. Pollution control devices – As already mentioned, there are two types of pollution control devices: one that collects dry dust and one that collects wet dust. The dry dust collector traps heavy particles from the drum, while the wet dust collector sucks finer dust particles that may escape from the dry dust collector.
9. Load out conveyor – A load out conveyor collects hot asphalt mix and sends it to the storage silo or small hopper where it can wait until the delivery trucks arrive.
10. Control panel – The control panel is the main hub of the plant. It contains different buttons that allow you to control the movement of the parts in the machine. From changing the quantity of ingredients to increasing or decreasing the output of asphalt, the control panel is responsible for everything. Therefore, hire a well-trained technician who knows how to operate a drum mixing asphalt plant. Get more elaborated details here: https://aimixasphaltplant.com/small-portable-asphalt-mixing-plant/.
Buying a drum mixing amp aspal is profitable for construction companies as they don’t need to buy readymade asphalt from other sources. This means you save a lot of money in the long run if you know how to run the machine.
