QLBY Series Mobile Asphalt Mixing Plant


QLBY Series Mobile Asphalt Mixing Plant, just as its name implies, it is a kind of construction machine to produce the asphalt mixture. But the key is that this machine can move easily and without the limitation of the construction sites. Because its stock bin and mixing drum are equipped with tires. It is usually used to mix asphalt mixture, modified asphalt mixture and colored asphalt mixture for the requirement of highway construction, grade highway construction, city road construction, port construction and airport construction, etc. And according to the installation, there are mobile type and stationary type. But in detail, mobile type also can be divided into two sorts of different mobile asphalt plants. One is double drum type and another is compulsory type. In addition, there are countless mobile asphalt plant manufacturers in the market now, so it is difficult to find a proper machine, and this article aims to introduce some relevant information about mobile hot mix plant to you from six aspects of the definition, purpose, classification, components, working principle, characteristic, and hope it will bring you enormous harvest during the selection of mobile asphalt batch mixing plant.

1. Cold aggregate supply system. Cold aggregate usually is break stone;

2. Tilted belt feeding conveyor. It is used to lift the cold aggregates to the drying system;

3. Drying drum. In the drying drum, the cold aggregates will be heated and dried;

4. Burning system. It exists in the drying drum and is to heat and dry the cold aggregates;

5. Hot aggregate elevator. It is a lifting system used to lift the hot aggregates to the next system;

6. Vibrating screen. The hot aggregates are sent to the vibrating screen through the hot aggregate elevator. And vibrating screen begins to screen the aggregates according to different diameters of the aggregates;

7. Storage warehouse. It is applied to store the proportioned hot aggregates;

8. Filler supply system. It is to store the mineral powder, such as sand;

9. Dust collecting system. In the process of heating and drying the cold aggregates, there will be some dusts produced, so this part is to do dust removal and send the dusts to the recycling powder storehouse;

10. Asphalt supply system. Offer the asphalt;

11. Mixing tower;

12. Pneumatic control system;

13. Electric control system. Control the whole working process;

14. Finished product storage bin. It is used to store the asphalt mixture.


Characteristics and advantages of QLBY mobile asphalt mixing plant

1. Modular design makes it more rapid and convenient to move;

2. Special design in mixing blades, with the special driving force, the operation of the mixing drum is more reliable and effective;

3. We adopt imported vibration motor to drive the vibrating griddle, which improves the efficiency and reduces the fault of rate;

4. Cloth-sack-type dust removal is in the oven-dried condition, it is equipped on the top of the mixing drum, which reduces the heat loss and saves the space and fuel;

5. The bottom structure of the stock bin is opposite, which reduces land occupation, cancels the lifting space of small lanes of finished materials and reduces the fault of rate;

6. Aggregate lifting adopts double row plate, which prolongs the service life of the elevator and enhances the stability of the function;

7. Adopt dual machine of fully automatic control computer or manual control with the automatic fault diagnosis procedure. The operation is safe and easy.

1) Characteristics of double drummobile asphalt plant

1. Unit design of batch-type drying drum and mixing drum, which saves a lot of investment costs;

2. Drying the materials when the drum rotates clockwise, and discharge the materials when the drum rotates anticlockwise. And the whole structure is compact and simple and is easy to operate;

3. Intensive PLC control, touch screen operation, can switch freely between the automatic operation and manual operation;

4. Mobile chassis structure makes the installation and transportation  more speedily and convenient;

5. Dual-purpose burner with oil or coal, you can choose any one of these two fuels for your project.

2) Characteristics of compulsoryasphalt mixing plant mobile

1. Unit design of batch-type drying drum and horizontal twin shaft mixing drum, which can mix the materials thoroughly and the finished product will have better quality;

2. Accurate weighing and stable quality;

3. Similarly with the double drum mobile asphalt batching plant, drying the materials when the drum rotates clockwise, and discharge the materials when the drum rotates anticlockwise. Moreover, the whole structure is compact and simple;

4. Intensive PLC control, touch screen operation, can achieve free switch between automatic control and manual control;

5. Mobile type chassis makes the transportation and installation convenient and fast, burner can be supplied with coal or oil, it all depends the selection of the customers.


Working principle of mobile asphalt plant

The working principle consists of three steps. And the asphalt mixture is made of cold aggregate, mineral powder and asphalt. So after finished the arrangement of these three materials, discharge them into the mixing drum and begin to produce the asphalt mixture. The following is detailed working process.

1. Break stones through the tilted belt feeding conveyor are sent to the drying drum from the cold aggregate supply system, and then the materials will be heated and dried by the burning system, then the hot aggregate will be lifted through the hot aggregate elevator to the screening system, and the hot aggregates will be screened according to the diameters of the aggregates. Next, send the aggregates to the hot aggregate stock bin, and the aggregates enter into the aggregate weighing system, after the weighing, discharge the proportioned aggregates into the mixing drum;

2. In the process of heating and drying in the drying drum, there will be some dusts produced, and the dusts enter into the dust collecting system and after the dust removal, enter into the recycling powder storehouse. The mineral powder enters into the mineral powder stock bin. Then, combine the sand in the recycling powder storehouse with the sand in the mineral powder stock bin, discharge these two powders into the powder weighing system and after the weighing, discharge them into the mixing drum;

3. Asphalt will be pumped into the asphalt tank through the asphalt pump, moreover, asphalt tank has a heating and insulated effect on the asphalt. And then send the asphalt to the asphalt weighing system and after the weighing process, discharge the asphalt into the mixing drum.

After these three preparatory processes above, begin to mix according to the designated time and after the mixing, discharge the asphalt mixture into the finished product storage bin. And then discharge them into the heated bitument tanker. There are too numerous mobile asphalt mixing plant suppliers to mention one by one, while our company has devoted ourselves to innovate our mobile asphalt plant for sale and learn form the other good factories for years, and we make up our mind to export our mobile asphalt mixing plant China to all over the world. And we will never stop doing this!

Finally, our company has many types mobile asphalt mixing plants for sale, stationary asphalt mixing plant, drum asphalt mixing plant, etc, and we sincerely welcome you to contact us and get the detailed information.
