What Is Asphalt Batching Plant?


What is asphalt batching plant? Asphalt batching plant refers to the whole large set of equipment used for manufacturing asphalt mixture. It mixes various aggregates (sand and stones), bond (high temperature liquid asphalt or residual oil) and mineral powder in proportion to form asphalt mixture.

Compared with continuous asphalt mixing plant, asphalt batching plant mixes materials batch by batch in the mixer instead of continuous yielding methods.

With higher precision of measurement, higher level of automation and higher quality of production, it is widely praised by investors.

What Are The Main Components of Batch Asphalt Plant

As the picture shows, batch asphalt plant consists of multiple function components. Following the working process, they will be briefly introduced as below.

hot mix plant

Cold Feed Unit >>

This functional unit is mainly used to collect cold aggregate as particle size and types. Including cold aggregate bins and cold aggregate batching machine.

Usually, asphalt paving construction requires 3 kinds of stone, so the standard configuration is 4 bins. The number of the aggregate bins is depended on the rated output capacity of the asphalt plant as following table:

Rated Produce Capacity(T/h)Number of bins

The size and number of aggregate bin can be customized, which will affect the specifications of the two belt conveying machine, and the feeder specifications of the cold hopper feeding port ( belt width, motor reducer power size, etc.)

The filter sieve can screen out the large aggregate.

The aggregate batching machine with weighing system is installed under each bin.

Belt Conveyor >>

The two machines are both composed of motors, reducer rollers, roller tensioning machines, etc.
By them, cold aggregate is conveyed to the dryer drum.

Belt conveyor includes cold aggregate flat belt machine and tilted belt machine.

Drying And Heating System >>

The drying cylinder consists of motor, reducer, feeding box, unloading box and so on. The drying drum is continuous drum type with stirring blade device.

It is consisted of two parts: drying cylinder (drying) and burner (heating).

There are two types of heating method: down-flow heating and counter-flow heating.

The size of the drying cylinder is related to the standard asphalt station configuration, but also can be customized.

For the work efficiency of the asphalt mixing station, it is suggested that customers choose plants according to the standard configuration.

The burner system can be divided into fuel-oil type, coal type and gas type. The three types vary in price, depending on the availability of locally sourced fuel.

Fuel tanks can be shared with thermal oil furnaces or used independently.

It usually consumes 7 kg of fuel oil, 8 cubic meters of natural gas and 12-15 kg of coal to produce 1 ton of asphalt mixture.

In addition to the three types of burners mentioned above, there is also an burner that can be more flexibly adapted to the field fuel situation of both oil and gas.

The First Dust Collection >>

The first dust collection system is based on the heating and drying system. Generally, gravity collection method is adopted here.

Bucket Elevator >>

The dried aggregate is sent to the next process by the bucket elevator.

Hot aggregate lifting system is mainly composed of motor, check mechanism, temperature sensor, tensioner, tensioner lead screw, lifting hopper and plate chain.

According to the output of the whole machine, the 40T/h mixer is equipped with 40T hoist.

Mixing Floor System >>

Mixing floor system is mainly composed of vibrating screen system, thermal silo, metering system, mixing system and so on.

1. Vibrating Screen System

The hot aggregate is transported to the top of the mixing building by the elevator, and enters the vibrating screen process, which is the first process of aggregate into the whole mixing building. Vibrating screen system is mainly composed of vibration motor, screen and machine shell. The mesh aperture size can be selected by the customer.

Vibration motor is divided into two types: single shaft and double shaft.

2. Hot bin hoppers

After screening, the aggregate is stored in different hoppers of the hot bin. The hot bin is equipped with material position display, which can detect the amount of material. The cylinder doors are automatically controlled by an electrical control system to match the precise ratio of ingredients. The capacity of hot bin can be customized. And a layer of hot bin can be added if the capacity is large.

3. Weighing system

The measurement system is the key link to complete the accurate mixing. In general, the measurement accuracy of domestic equipment is ±1% (stone) and ±0.5% (asphalt and powder).

While the aggregate is loaded into the measurement system, powder and asphalt goes into their own measurement system separately. Aggregate measurement, powder measurement and asphalt measurement are all static measurement.

Powder metering includes the weight of new powder and dust removal system recovered powder. The proportion of recycled powder shall not exceed 20% of the whole powder composition.

About the mix ratio, the proportion of asphalt and powder is basically unchanged. The proportion of same particle size stone is different according to the asphalt pavement construction specifications and construction mix ratio to determine the proportion of each component.

4. Mixing system

Mixing system is mainly composed of mixing cylinder, mixing host system, cylinder door automatic control system, asphalt spraying device and so on. There are two forms of asphalt spraying, self-weight and pressure spraying.

Note that once the system is selected, the speed of the mixer is not adjustable.

5. Dust removal system

Dust removal system leads dust by induced draft fan, and dust will be collected and sent to the dust recovery system, by which dust can be reused as powder.

There are many dust removal methods, bag dust removal, water dust removal, volute dust removal, cyclone dust removal, gravity dust removal, etc.

Powder Supplying System >>

Powder supply system is composed of powder silo body, arch breaking device, screw conveyor and so on.

Bitumen Supplying System >>

The main principle of the asphalt heating system is to heat the heat conduction oil through the burner of the heat conduction oil furnace, and transfer the heat to the asphalt in the asphalt tank through the heat conduction oil pipeline in the middle of the asphalt tank, so as to achieve the final purpose of heating the asphalt.

The burner of thermal oil furnace is divided into three kinds: oil, gas and coal. Asphalt tank is divided into vertical and horizontal kinds. In order to transport thermal oil to each part of the oil pipeline, circulating pumping system is adopted to keep the thermal oil circulating in the pipeline. The circulating pumping system is controlled by a special electrical control system. The fuel is stored in fuel tanks.

Electrical Control System >>

Control system is the center of the whole asphalt mixing station, all the actions are completed by the computer controller through the pre-designed program, automatic control.

How Does Asphalt Batching Plant Work?

All kinds of aggregates after transporting, drying, heating, screening, measuring are fed into the agitator.
Another kind of raw material, mineral powder, after measurement, is also sent into the agitator, through the screw conveyor.

The third kind of raw material asphalt is heated into liquid and kept at 180-220℃. After accurate measurement, it is also pumped into the agitator.

Agitator uniformly mixes all kinds of raw materials to ensure fully contact fusion and finally form the asphalt concrete mixture.
