Efficient Bitumen Mixing Plant

The bitumen mixing plant like an “assistant” for road construction is the essential equipment for pavement projects. The construction industry constantly forges ahead after its establishment. All around us in every direction, as far as we can see that the jumbo airports, coastal ports, parking lots and expressways are distributed to the application of bitumen mixing plant.

What is Bituminous Mixing Plant?

The bituminous mixing plant, also referred to as bitumen mixing plant or asphalt mixing plant is the plant that is used to mix asphalt mixture. The bituminous mixture is that the aggregates (sand, stone) in different particle sizes, binders (asphalt or residual oil) and fillers (mineral powder) are mixed according to specified proportion.

And it can produce asphalt mixture, modified asphalt mixture and colored asphalt mixture.

According to transportation type, the bituminous mixing plant can be categorized into three types:

Based on the mixing method:

It is divided into the

What is Asphalt Mixing?

Asphalt mixing is the process of combining the bitumen with other fillers, which can be summarized in asphalt-aggregate ratio or oil stone ratio.

Asphalt aggregate ratio refers to the percentage of asphalt to mineral aggregate mass ratio in asphalt concrete. These materials of different quality and quantity are mixed to form different structures and have different mechanical properties.

It is one of the indicators of asphalt dosage. Its dosage directly affects the pavement quality. If the asphalt aggregate ratio is high, the pavement is easy to be oily, otherwise, it will affect the strength and waterproof effect. Generally, the oil stone ratio of SMA (stone mastic asphalt) is about 5.5%~5.6%, and that of SAC (stone asphalt concrete) is about 4.5%~6.01%.

What is Bitumen Mixing Plant Used for?

The asphalt plant or bitumen mixing plant, also named asphalt concrete mixing plant is the mechanical equipment which is to produce various bituminous mixture, it is also the essential equipment for these following construction projects such as urban-rural highways, jumbo airport, costal ports, parking lots and freight yards.

Bitumen Laying Plants

Bitumen laying plants, also known as asphalt or bituminous paver, belongs to a type of road construction machine which is used for paving road pavement materials. And it is a machine that evenly paves the asphalt mixture on the road base, and performs preliminary compaction and leveling.

Bitumen Hot Mix Plant

A bitumen hot mix plant is designed to mix aggregates of different particle size and fillers (mineral powders) according to a certain proportion to produce the bituminous mixture with the effect of binder (bitumen or residual oil) at a specified temperature.

A bitumen hot mix plant has another name — asphalt mixing plant, which can produce bituminous mixture, modified bituminous mixture and colored bituminous mixture, and has been playing a significant role in these construction projects such as motorway, grade highway, urban road, airport and port.

The main raw materials of bitumen hot mix plant include bitumen, stone, fly ash, etc. It has the following characteristics: fireproofing, waterproofing and noise reduction.

Bitumen Batch Mix Plant

The bitumen batch mix plant is the equipment that the components(macadam, sand, limestone powder and asphalt) are relatively measured accurately in a certain proportion, fed in batches and mixed forcibly. The production of the bitumen batch mix plant can summarize in this way: measurement in batches–feeding in bitches–forced mix in batches–discharging in batches.

The aggregates are calculated after drying. The drying and heating of the cold aggregate and the mixing of mixture are respectively carried out in two different assembly devices (drying drum and mixer).

The drying and heating method of the cold aggregate is flame counter-current type. It is featured by high automation and preparation quality of bituminous mixture, good drying and heating effect, small residual water content of finished materials and wide application range. However, using a bitumen batch mix plant generates a large amount of dust, and the cost of the relevant dust removal equipment is very high.

Mobile Bitumen Plant

The mobile bitumen mixing plant refers to the plant which is mounted on a trailer frame and can be transferred based on the different construction sites. It is suitable for these projects such as the county-rural roads, low grade highways, road maintenance and mountainous highways.

Bitumen Plant Near me

Bitumen plant near me generally can be categorized into two types according to manufacturing technique or mixing mode.

Two Basic Types Bitumen Mixing Plant Near me

There mainly exists two basic types bitumen plant near me: continuous drum type and forced batch (or intermittent) type according to technological process (or mixing mode).

The continuous (drum) bitumen(mixing)plant near me is the plant that heating and drying of the cold aggregate and the stirring of mixture are continuously carried out in the same drum. The production process of bituminous mixture is that each component (gravel, sand, stone powder, asphalt, etc.) is continuously and dynamically measured in proportion, and continuously fed and drum drop mixed.

A batch mix bitumen plant near me refers to the plant that the production of bituminous mixture is carried out batch by batch.

Working Process of the Bitumen Plant Near me

The following paragraph is a statement or expression of the working process of the bitumen mixing plant near me.

After the central control room sends the boot command, the cold materials in the cold bin are first transported to the drum dryer through the belt conveyor. Then the aggregates dried are transported to the vibrating screen for screening via the hot material elevator, and the screened aggregates fall into each hot aggregate bin.

Next The powders and screened aggregates drop into the corresponding weighing hopper from the outlet of the respective storage bins, are measured by the electronic scale, and are dropped into the mixing tank. Last the weighed hot asphalt is also sprayed into the mixing tank.

After various mixtures are fully mixed, the mixed bituminous material is produced and it’s unloaded into the hopper car. It is unloaded into the bituminous mixture storage bin through the track, and finally the mixed material is placed on the transport vehicle through the unloading gate.
