Asphalt mixing plant

The Asphalt Mixing Plant with the production capacity from 40t/h to 400t/h is the ideal equipment for construction and maintenance of high-ways. It introduces the German and Italian technology advanced designed and well manufactured. The plant is modular construction and easy to transport, install and dismantle. Its main parts adopt well-known brands components. The mixer has a fast speed and short mixing time. The rated working cycle is 45s. The filling rate is no more than 60% making asphalt, aggregate and powder well stirred. Its mixing plate and blade use wear-resistant ally cast iron and its mixing shaft adopts ally cast steel. The measuring device use OMRON weighing module which equipped with high precision and reliability resistance type strain sensors. It can adapt to any environment. In addition, the aggregate, powder and asphalt are measured separately to guarantee the precision and accuracy. The control system using Siemens programming controller can carry on the automatic and manual control for the charging, weighing, mixing, discharging and so on. The dust collecting system adopts the combination of gravity dust collection and water dust collection or the combination of gravity dust collection and bag dust collection. Dust emission is less than 50 mg/Nm3 with no pollution to the environment.

Cold Aggregate Batching System
1. Modularized structure, reasonable layout and it is convenient to dismantle and replace.
2. Under each cold aggregate bin there is a belt feeder adopts frequency convertor and the reducer motor, which is compact and low rate of fault. By changing the rotate speed of the feeding belt conveyer and the size of the gate, the sand stone can be changed; there is material lacking alarming device at the discharging port.
3. The vibrator on the wall of the sand stone bins to ensure the normal working.
4. The large volume hopper with a wide port is convenient to charge. On the top of each bin there are insulation net which prevent large size aggregate entering.
5. All the conveyers adopt circular belt without joint, so it runs smoothly with low noise and long service life.
6. Add primary sieving device, a vibration screen is settled at the entry of the feeding conveyer to prevent the stone with large diameter entering the dry drum, and this largely decrease the scrap.
7. The collecting conveyer and feeding conveyer are driven by electronic drum, which is simple structure and low repair rate.
The batching system consists of batchers, collecting conveyer and feeding

bag dust gather

1. This system equipped with primary gravity dust-catcher and all the aggregate grain collected is conveyed to the hot aggregate elevator for recycling use.

2. The secondary dust collecting system is high-pressure impulsive sack dust catcher with isolated chambers. The material of the sack is the felt of American NOMAX, its guarantees long working under rated high temperature, it has long life-span and good ventilation. Its object is the powder whose diameter I under 75μm. The efficiency of sack dust-catcher can reach more than 99.5%,preceding to the environment protection standard of our nation.

3. The collected powder is into the recycle bin through a three-blade fan and pipelines. When there is no necessity to recycle, the collected powder is discharged by screw conveyer.

4. The three-dimensional dust-catcher, the heat-preservation structure of the upper and lower tank body avoid the agglomeration and leakage of the powder, its outer shell is wrapped by colorful steel, so it is sightly to look.

the drying drum

1. The drying drum systemis the key component of the whole set, the capacity directly influences the productivity; the temperature of the dried aggregate directly influences the temperature of the final product; Drying efficiency directly influences the consumption of the fuel, thereby the reasonable structure is very important. We fully absorbed the abroad advanced technology of mixing and got satisfying effect and realized the anticipated object.
2. The drying drum is droved by frictional wheels, which is droved by four synchronous motors. It can run smoothly with low noise, this avoids the large impulse, sound noise caused by large gear and chain driving manner.
3. The structure of drying drum is drum-type; the gradient angle is 5°. It is fixed in a lower trestle set to have a lower bar center to run smoothly.
4. The flinches of the drying drum lays reasonable and improved the v thermal efficiency. The fitches joint with drum by bolts which make it easy to change the fray one. And avoid the transmutation and Exfoliated caused by jointing.
5. The mineral wool heat preserving added in the outside decreased the loss of heat, thus decreased the consumption of the fuel and increased the drying productivity, The wrapper in the outside use stainless steel, so it is sightly to look.
6. The discharging manner is scraper sideway discharge from the bottom, the port is low, so the output is even and smooth.

The Weighing System of Hot Aggregate Bitumen and Powder

1. Aggregate weighing, the four doors of the hot aggregate hopper is controlled by twin-routine drum. When working it is fully open and then close 2/3, finally completely closed. That realized the cursory discharge first and the discharge precisely, this is helpful to the stability of the compensation and efficiently promotes the weighing precision of the aggregate.

2. Powder weighing: Equipped with broken arch pneumatic devices, it works smooth fast; Special screw conveyor make the powder rapidly into the mixer, uniform and effectively ensure the quality of the final product; it uses pneumatic Butterfly to control the stuff-giving and uses screw conveyer to transport stuff, the ration door designed like a herringbone and let the stuff leaks fast.

3. The asphalt pump, which adopts up-magnetic ejection, and distinguishingly designed pipelines ensuring the stability of the asphalt flux, so keeps the stability of the impulsion compensation, thus promotes the weighing precision. The heat-preservation of the asphalt weighing barrel introduced special heat-conducting oil heater, this is not only efficient but also avoid the influence of the heat-conducting oil.

4. Among the three weighing manner, the asphalt weighing adopts two-point checking, while the aggregate and powder weighing adopt three-point checking. The sensors introduced American Media which belongs to high-precise, sensitive resistance strain sensors. Its structure is like cut girder, fully sealed, so it can adapt all the bad conditions and keep its precision and reliability.
