Asphalt Batch Plant First Time Start UP

-

When the equipment arrives to the job site in a dismantled condition it becomes very important to install each component properly and take a dry trial run of them prior to the actual mix run. Below are some important points to note for the first time start-up of Atlas asphalt batch plant. Atlas does support its customers with on site support for installation, operation and maintenance of the equipment. All the points are usually checked and taken care of by our technicians physically as they are present at the site. Due to COVID-19 we are unable to send our technicians to many job sites and hence this guide comes handy. Things to Note Before Starting the Asphalt Batch Mix Plant

- All moving parts have to be greased before starting the plant.

- Oil to be filled in all the components before starting the plant. - All feeder belts have to be set and aligned before starting the plant.

- After the first empty run, all nuts and bolts of the plant have to be tightened.

- The first 5-6 batches of plants operation have to dry batch.

After that, tighten the vibrating screen nut bolts and mixer arms and tips and liner tighten and weld the same. When viewed from the burner side,

- Drum should rotate clockwise.

- Opposite to the drum drive gear box there is an idler sprocket. Its shaft has to be daily greased.

- Dryer drum ring and sprocket has to be oiled and greased daily. - Check the position of the burner blower motor rotation.

- Vibrating screen motors should be rotating in the opposite directions.

- One motor should rotate in clockwise and the other motor in anticlockwise direction.

- The Elevator side motor should rotate clockwise and the other motor anticlockwise.

- Aggregate weighing hopper and hot bin gate cylinders open to open the gates.

- Mixer paddle arms rotation from gear side should be in such a way that the right shaft is rotating clockwise and left shaft is anticlockwise.

- Check only one motor (shaft) at a time. When viewed from the motor side should be rotating anti-clockwise,

 - Exhauster impeller.

- Check oil level in air compressor before starting the plant.

- Remove air from the compressor at the end of each day's operation. - Remove water from the compressor's tank each morning.

- Bag filters has to be heated for 20-30 mins before starting of operation daily.

- During this time run the bag filter exhausted, drum and burner blower on at very low temperature (flame).

- Before shutting down the plant run the dryer empty for 30 mins (without any material).

- During this time the burner blower, bag filter cleaning mechanism, bag filter bottom screw, exhausted should be on.

- When the plant is shut down all the components should be empty including the hot bins.

- Last batch from the mixer has to be dry batch without bitumen, without binder so that the mixer is cleaned.

- The plant will not be running to its maximum capacity for the first few days. Only after the initial few days of operation, it is advisable to increase the batch size.

The Way An Asphalt Batch Mix Plant Functions

Mixing different sizes and grades of aggregates in asphalt mix plants produces asphalt material. These aggregates are mixed with the appropriate amount of liquid bitumen, and heated together to create hot asphalt mixture. Asphalt is a mix of bitumen and pulverized stones that is used for making pavements. There are a few factors that determine the characteristics and quality of an asphalt mix. These factors include the amount of aggregate used and the type or recycled pavement. How does hot mix asphalt get made? Once the aggregates have dried, they are heated to coat them with bitumen. You can dry the aggregate by rolling it in a dryer drum. To evaporate dampness and generate heat, the dryer drum is heated to below. The aggregate remains in the top half of drum. The interior contains several types of flight that heat the drum. The mixing chamber is where the aggregates are covered with bitumen.

Hot mix asphalt is made by an asphalt mixing plant. HMA stands for hot mix asphalt. This hot mix asphalt is widely used in road construction. A specific recipe is used to make hot mix asphalt. It is composed of various types of aggregates, bitumen and filler material. There are many sizes of aggregates. Here are some hot mix plants examples: Batch type – It produces hot asphalt mixture in small batches. Drum/continuous type: This is HMA in continuous process. These asphalt mixers can be used to make hot mix asphalt. HMA is possible, even though the process is quite unique. HMA is produced in batches rather than by continuous (drum) plants. High quality end products can be produced by batch plants, which are more reliable and advanced. They are also more expensive to buy and maintain. Drum plants are easier to set up and less expensive to maintain.
