Technological Advantages: Why Choose XUETAO Indoor Environmental Protection Plant?

1. Compact, Low-Height Design

Traditional asphalt mixing plants typically exceed 25 meters in height, making them difficult to install indoors. XUETAO's optimized modular structure compresses the total height of the In-House Environmental 320TPH Asphalt Mixing Plant to 18.5 meters. This allows customers to set up production lines within standard industrial buildings, complying with urban planning restrictions on building height and effectively preventing pollution spillage through the external building structure.

2. Multi-Point Smoke and Odor Control System

To address the blue smoke and odor generated during asphalt heating and unloading, XUETAO employs multi-point collection technology:

Mixing Tank Unloading Port: Equipped with a fume hood and dust collection device.

Asphalt Tank Breathing Inlet: Exhaust gases are introduced into the burner for secondary incineration via pipelines.

Indoor Ventilation: The workshop walls are equipped with an air circulation and filtration system, ensuring both indoor and outdoor air exchange and deep purification of exhaust gases.

3. High-Efficiency Noise Reduction and Dust Control Solutions

Mechanical Sound Insulation: Sound-absorbing and heat-insulating cotton is installed on the outer layer of the elevator, vibrating screen, and hot material silo to reduce the sharp noise generated by stone collisions.

Automatic Feeding System: A fully automatic grab bucket and sealed conveyor belt are used, greatly reducing secondary dust raised by the forklift when operating in the raw material area.

Emergency Spraying: A high-pressure water mist spraying device is installed on the roof of the plant, which can quickly suppress dust in case of an emergency increase in dust.

Comparison of Conventional and In-House Environmental Asphalt Mixing Plant’s advantages:

The Hangar “in-house” environmental protection asphalt plant achieve the environment requirements of city, consist with follow four system:

1.Lower elevation type asphalt plant, the top point is 15m.

2.fully enclosed workshop

3.ventilation and dust, smell remove system

3.1 ventilation circulation and dust collection device outside of the workshop (matched with workshop)

Although we have taken various environmental protection method on the asphalt plant, but there is always a very small amount of dust and smell remain internal, especially the taste will affect the work environment. It is necessary to make the air inside exchange with external constantly.

We equipped with air supply and exhaust system on the wall, so that indoor air can be circulated with new air outside. The air pumped to outside will be passed collecting and processing, thus ensure internal air environment while no polution for the external environmental pollution.

3.2 water automized spraying device(matched with workshop)

In general, there will be no dust generated in the plant, but there will be more dust when the accident occurs, it will affect the working environment inside. The problem can not be solved quickly by the conventional ventilation cycle, therefore, the device can be used as an emergency measure to quickly recover a good working environment.

At the top of the plant to install sprinkler system, the use of high pressure water pump to spray water, if the plant sudden dust increase, you can open the system, it can play the role of rapid dust removal

3.3 bitumen flue gas,dust collecting and disposal device(matched with asphalt plant)

Setting absorb flue gas and collecting dust system at the mixer discharge door;

Air-vent of bitumen tanks was connected by pipeline to burner;

Dust cover setting on the cold feed hoppers and conveyer;

3.4 Noisy remove device (matched with asphalt plant)

Hot elevator, vibration sieve, hot bin with external sound insulation and heat preservation device, can effectively reduce the friction sound of aggregate with steel.

3.5 Sulfur dioxide treatment device(matched with asphalt plant)

3.6 We put the air compressor, draught fan, filler silo and other parts that easily generated noisy and dust in a separate space inside, as far as possible to reduce the impact on the indoor environment.

4. other auxilary system

4.1 automatically loading material system

The workshop is divided into asphalt mixing plant installation area and raw material stacking area. The raw material stacking area uses an automatic feeding system, which can send the stone to the corresponding pile according to various specifications. The signal is transmitted to the computer through the material level device installed on the cold hopper during production, and the computer controls the grab bucket to send the material to the cold hopper where the stone needs to be added. Greatly reduced dust.

4.2 Track type mobile inspection trolley

Because In-House Environmental Asphalt Mixing Plant is installed indoors, there are more columns, and the crane is difficult to operate indoors, which brings great trouble to replace the parts.

According to the asphalt plant flow-type structure, centralized layout, low height characteristics, in the main equipment area design and installation of a set of track type mobile repair trolley, perfect solution to the equipment daily maintenance and repair. The device can lift all parts, no longer need crane, not only easy to use, but also save the cost of use for users.

Maintenance and Operation Support

To address the challenges of limited indoor space and the difficulty of accessing traditional cranes, XUETAO has integrated a track-mounted mobile maintenance trolley within the main structure of the In-House Environmental 320TPH Asphalt Mixing Plant. This system covers the lifting path of all core components, facilitating routine replacement of liners or motors, reducing maintenance complexity, and saving users expensive external lifting costs.

Frequently Asked Questions (FAQ)

Q: Can the output of the In-House Environmental 320TPH Asphalt Mixing Plant reach the level of the AMP4000? 

A: Yes. The design capacity of the IH·AMP320 model is comparable to the traditional AMP4000 model, but it has a higher footprint and space utilization rate, making it more suitable for industrial parks.

Q: What are the requirements for plant height for this indoor station? 

A: A net plant height of approximately 22 meters is recommended, as the highest point of XUETAO equipment is 18.5 meters, leaving space for the installation of overhead cranes, ventilation ducts, and lighting facilities. 

Q: Can the equipment support multiple fuels?

A: Yes. Our combustion system supports diesel, heavy fuel oil, and the more environmentally friendly natural gas, allowing you to choose flexibly based on local energy prices.
