The HLB-8/15/20/30 series mobile double drum asphalt concrete mixer is carefully designed and manufactured by our company in response to market demand. It is different from general drum mixers in that its unique middle reversing feeding device, middle induced draft, and double drum structure give the whole machine the outstanding advantages of drum mixers, as well as the advantages of easy measurement, accurate mixing ratio, and reliable mixing quality of traditional mixers. Years of production practice have shown that this series of products is an optional mixing equipment for asphalt road construction and maintenance.
Main structural features:
1. Using a drum as the main structure to achieve intermittent feeding and drying, with high mixing efficiency.
2. The model has a compact structure, is lightweight and flexible, has a trailer type chassis, and is very easy to move and position.
3. Widely adaptable, it can easily add mineral powder and mix asphalt mixtures with more diverse formulas.
4. By using timed and constant volume injection of asphalt, the oil stone ratio is accurate and easy to adjust and change.
5. The quality of the finished material is reliable, the temperature is stable, and the mixing is uniform, especially in the middle of the induced draft dust removal, which avoids the fatal weakness of asphalt aging in the single drum mixer.
6. The burner design is innovative, with a dual-use of kerosene and electronic automatic ignition. It burns thoroughly, is not prone to slagging, and has high thermal efficiency.
7. Touch screen display, PLC programmable centralized control, automatic, semi-automatic, manual operation.
Automatic metering and batching station
The automatic metering and batching station adopts a three bucket cumulative metering method, using a loader for matching aggregate supply operations. Electronic cumulative metering is carried out through a PLC programmable controller, with automatic compensation for differences, high metering accuracy, and small errors. The belt conveyor is equipped with a belt scraper and a deviation adjustment wheel.
Note: Our company can also design the batching station as a movable structure according to customer needs.
Drying drum and mixing drum
1. The cylinder is made of high-strength alloy structural steel Q345 (16Mn), which has the ability to resist erosion and high-temperature deformation.
2. With a special blade arrangement, the material forms a strong axial movement inside the cylinder, ensuring uniform heating and stirring of the material, thereby greatly improving the quality of the finished product.
3. The cylinder has a thrust device to prevent axial movement of the drying drum during rotation, thereby avoiding wear on the end of the supporting roller and the collision and wear of the sealing rings at both ends of the cylinder.
4. The main moving parts are connected with labyrinth seals to prevent dust from overflowing and achieve good sealing effect.
Burner
Adopting internationally renowned burners with high technological content, high flame temperature, sufficient combustion, low fuel consumption, and significant economic benefits. Suitable for various fuels, such as heavy oil, diesel, natural gas, liquefied gas, coal, etc.
Finished product warehouse
The finished product warehouse is lifted by a steel wire rope winch, which comes with a brake device and a large cylinder diameter cylinder opening the door for unloading. The capacities are 2.5 tons, 5 tons, and 9 tons respectively. The lifting bucket adopts dual stroke limit and PLC time control three-level protection, which ensures stable operation, safety and reliability.
Control room
The control room is exquisite and beautiful, providing users with a comfortable and spacious operating environment, greatly reducing adverse factors such as dust and noise. The control room is in a detachable form, equipped with split air conditioning, aluminum alloy sliding windows, and wooden floor decoration, creating a spiritual space. Operators can achieve automated centralized control of equipment operation in the control room, making it easy to operate
。
Operation cabinet
1. A brand new independently developed configuration software that achieves a user-friendly interface and human-machine dialogue function,
2. Touch screen display, PLC programmable controller centralized control, capable of fully automatic, semi-automatic, and manual operation. Simple and convenient operation, intuitive interface.
3. Unique weighing function, stone weighing adopts cumulative measurement, fast replenishment, and automatic compensation for differences.
4. Powerful query function, record and print main production data.
5. Multi directional practical process flow, convenient management of formulas and production parameters.
6. Powerful and accurate fault monitoring and alarm functions.
Coal fired (oil fired) direct heating asphalt tank
This equipment is a coal-fired (oil fired) direct heating asphalt storage and heating tank designed for road construction and maintenance units. The equipment has functions such as asphalt storage, preheating, dehydration, heating, temperature indication, and high temperature alarm. It is movable as a whole, easy to lift, maintain, and transport, and does not require the construction of a foundation for installation. It can be ignited and produced on a simple and flat site. During the heating process, the asphalt process is automatically operated under negative pressure, and the pump and pipeline are preheated by themselves. The intermediate program does not require direct manual operation. During equipment operation, only water and coal need to be added, ash and slag should be removed, and high-temperature asphalt should be pumped out.
YK-20/30/50 asphalt heating tanks have storage capacities of 20m ³, 30m ³, and 50m ³, respectively. The output of finished asphalt from a single heater is 4-5T/hour.
