Anatomy of a mini bitumen sprayer.

-

They are the ones which help spray bitumen on the road before the actual laying takes place. The spraying is controlled which does not allow wastage of bitumen. Mini bitumen sprayer is one such equipment which is one of the most useful for road construction projects. To understand the usefulness of this equipment we need to understand the basic working of a truck mounted sprayer. Spraying is fixed by a truck mounted sprayer as it is fitted with a spray bar of fixed length. This spray bar is also fold able which means you can adjust the spraying width to cover maximum width of the road in at a single flow. But the variable width of the road does not always allow to get best spraying width. It is also uneconomical to allow the sprayer to run over the same surface again just to complete spraying in the remaining part. Related: See details of truck mounted bitumen pressure distributor.

Here comes the small bitumen sprayer for spraying of bitumen on the sides of the road. Essentially this equipment comes with a hand spray flexible pipe which will help you to spray bitumen on the sides of the road where the bigger sprayer can not reach. This is a very small and mini machine built on its own chassis and is self tow able. The anatomy of mini tar sprayer is explained in the image below.

The important components are as:

- Storage tank: Storage tank is insulated by glass wool to retain heat and keep the bitumen hot for a long time. Its size can be customized.

- Burner: Singe pressure diesel burner is simple yet effective and does its job perfectly.

- Engine: This 6.5 HP diesel engine does it job neatly. It powers the bitumen transfer pump and the air compressor.

- Bitumen pump and air compressor: Pump will effectively transfer the bitumen and air compressor can also be used for cleaning of the road.

- Spaying system: Hand spray pipe is provided for effective spraying of the bitumen.

- Cleaning system: Cleaning of the pipe lines is possible by the use of air and diesel.

- Chain block: An optional chain block mechanism can be provided so as to facilitate the lifting of drums and filling of the same easily.

- Towing hook: Simple towing hook which allows towing by any suitable vehicle.

Conclusion: This sprayer with hand spray bar can not be substituted with the truck mounted sprayers. The functionality and duty of this equipment differs from the one mounted on the truck. Yes this is a very inexpensive machine to maintain and own and is very useful for jobs that require finishing. The role of bitumen sprayers can not be neglected. They are the ones which help spray bitumen on the road before the actual laying takes place. The spraying is controlled which does not allow wastage of bitumen. Spraying is fixed by a truck mounted sprayer as it is fitted with a spray bar of fixed length. It is also uneconomical to allow the sprayer to run over the same surface again just to complete spraying in the remaining part. Check what is asphalt plant?  and how does asphalt plant work ? Here.

Asphalt Drum Mix Plant Operation And Components

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.

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.

An asphalt mixing plant is a key piece of equipment for road construction companies. Each asphalt batch plant has many functions. They are more complicated than drum-type asphalt batch mix plant operations. This article will highlight the basics of asphalt batch mix plant operation. The four major functions that are required to operate any asphalt batching plant are: Heating and drying the aggregates. Weighing aggregates, bitumen, and binder materials. Mix the bitumen, binder and aggregates. Hot mix asphalt is discharged. Types of asphalt plants The mixing plants can be classified as drum mix or batch mix. Asphalt Batch plants: These plants make hot mix asphalt in batches. Drum mix asphalt plant: This type of plant produces hot mix asphalt in continuous production. These plants are often called counter flow and drum mix plants. This is more than just a difference in production. Each equipment also produces different types of hot mix asphalt. This equipment can also be modified to produ
