HLB Series Mobile Drum Mix Asphalt Plant

The HLB series mobile drum mix asphalt plant is basically of four types: HLB-8, HLB-15, HLB-20, and HLB-30, which derive their name from their particular production capacity. The equipment is well designed and manufactured in response to the market demand. It differs from traditional ones in that its drum can rotate in the reversed direction to push the concrete towards the discharge chute. This drum mixer is also known for its dual drum configuration and a unique bag-house which is fitted in the middle of the plant.

Conventional drum mixers have multiple advantages such as ease of measuring, accurate batching ratio, and reliable mixing quality. This series of asphalt plant combines those said advantages of traditional mixer with the salient features of newly emerging ones. It brings to the market a proved design for use in the construction and maintenance of asphalt road.

Structures and Features
1. The mixer puts the cylindrical drum as its main structure. Material feeding and drying are done at proper intervals, which ensures high mixing efficiency.
2. The light, compact asphalt plant is also highly flexible. The trailer chassis can be easily and conveniently transferred to the job site.
3. The plant is highly versatile. By adding different pulverized minerals, it can mix a variety of asphalt recipes.
4. Bitumen is fed into the batching container at a specific time and volume to assure an accurate bitumen-oil ratio, facilitating ratio adjustment.
5. The plant features stable mixing temperature and uniform blending. The unique bag-house avoids the weakness of single drum mixer where the bitumen is susceptible to ageing.
6. Touch screen allows straightforward control. The PLC system allows for automatic, semi-automatic, and manual operations.
7. The novel burner design can both use coal and oil as fuel. Ignition is done electronically and automatically. Complete combustion can be guaranteed for high heat efficiency. No slag should be formed inside the batcher.

Automatic Batcher

The asphalt plant is quipped with one weighing hopper which can measure the combined weight of materials from the three material hoppers. A loader will supply required aggregates to each hopper.
Feed level can be measured and adjusted via the PLC system which can compensate for raw material shortage. This process features high measuring accuracy with little error rate. The belt conveyor is equipped with scraper and tracking adjustment roller.

Note: As the above picture indicates, our automatic batcher is also available in the mobile type if required by the customer.

Drum Dryer and Drum Mixer
1. The cylindrical drum is made from Q345 high-strength alloy steel, which is impervious to washing and high temperature without deformation. The cylinder has advanced structure whose manufacturing process is nationally unique.
2. The paddles are arranged in a spiral manner, which enables the material to move about violently in the axial direction. This process ensures an even heating over the material, and greatly improves the quality of finished products.
3. Thanks to the thrust-bearing, the cylinder is prevented from axial movement during rotation, which avoids the wear of the support roller and the seal ring at either end of the cylinder.
4. Labyrinth seals are applied to the joints between two main moving parts to prevent dust leakage and insure the joint a secure seal.

Burner
The burner is of international famous brands. It produces high-temperature flames for sufficient burning with low fuel consumption, which saves operation cost. A wide array of fuels can be applied to the burner, including heavy oil, diesel oil, natural gas, liquefied gas, and coal.

Finished Product Bin
The finished product bin is lifted up by the winch via steel wire rope. The winch is also fitted with a brake device. To dump the material, the large-diameter cylinder will open.
Available at volumes of 2.5 ton, 5 ton, and 9 ton, the bin is also fitted with a lifting bucket controlled by the dual travel limit switch and PLC time control. Stable in operation, the bucket is reliable to use.

Control Room
The spacious, beautifully designed control room provides a comfortable operating environment for users who want to work in a dustless, quiet cabin. The detachable cabin room is equipped with split unit air conditioner, aluminum alloy slide window, and wooden floor. While sitting in the room, operators can monitor and control all the running facilities with ease and convenience.

Operating Cabinet
1. The supervisory control and data acquisition software creates a user-friendly human-machine interface. 2. Touch screen allows production data to be presented on the visual display. PLC system provides automatic, semi-automatic, and manual operation modes. 3. Unique weighing functionality makes automatic, fast compensation for material shortage a possibility. 4. Main production data are recorded and printed for ease of search. 5. The mixing recipes and production parameters are conveniently managed to allow for diversified, practical processing procedures. 6. Machine fault monitoring and alarming system is responsive and accurate.

Fast Heating Type Asphalt Storage Tank

The fast heating type asphalt storage tank provides a solution for road construction and maintenance unit. Diversified functions are available, including asphalt storage, pre-heating, dehydration, heating, and temperature indication, and high temperature alarming. The whole equipment set can be moved, lifted, repaired, and transferred conveniently. Its installation does not require the construction of foundation. Simply laying it on the flattened ground, you can then ignite the equipment for work. Asphalt heating process is done automatically under negative pressure. Pumps and pipes are independently pre-heated. All those procedures do not require manual operation. Adding water and coal as well as removing slag is all that is needed to pump hot asphalt.
YK-20, YK-30, and YK-50 have a corresponding storage capacity of 20m³, 30m³, and 50m³. One set of heating equipment can accomplish production of 4 to 5 tones of asphalt per hour.
