Eco-Friendly Asphalt Mixing Plant, LBE Series
No finished asphalt storage bin, simple and easy set-up, less land
LBE series asphalt mixing plant is an integrated asphalt plant designed with no finished product bin, its optimized structure contributes in producing asphalt in an environmentally friendly manner. This series asphalt mixing plant is available in two structure types, i.e. modular semi enclosed structure and fully enclosed structure, to meet specific needs of our customers.
The design of a modular and semi-enclosed structure helps prevent the spread of dust and loose particles to other work areas, and ergonomic sliding door enables operation easier. Dust control measures are adopted at cold feed bins, conveyor belt under bins and truck loading area, ensuring that the asphalt mixing plants meet the environmental compliance requirements.
With a fully enclosed structure built in containers, the asphalt mixing plant provides superior look and easy installation. The completely closed construction paired with dust collection system efficiently prevents dust and fumes from escaping, offering outstanding environmental performance.
- Energy Saving
- All parts exposed to the atmosphere are covered with insulation layer to reduce heat losses;
- Electric heating method is used as alternative to conventional thermal oil heating for asphalt storage;
- Energy efficient motor reducer greatly reduces energy consumption;
- Foamed asphalt warm-mixing function makes production process more energy efficient;
- Dust Control & Deodorization
- Independently developed gas burner can meet the customer's requirement of clean-burning fuels;
- The flue gas will be transported to the burner for secondary combustion, thus preventing the asphalt flue gas from entering the atmosphere;
- Vent condensers are installed at vents of heavy oil and asphalt storage tanks to reduce blue smoke emissions. Optical oxygen catalytic and activated carbon adsorption can also be used for solving the problem of emissions.
- Cold feed system is fitted with pulse jet baghouse dust collector through ducting to remove dust generated during loading and conveying process;
- Reclaimed filler silo is fitted with wet mixing unit to reduce dust emissions;
- Foamed asphalt warm-mixing function efficiently reduce the smoke generated during the production process;
- Atomized mist unit can be configured to efficiently suppress asphalt dust at the site;
- Noise Reduction
- Induced draft fan features blower sound enclosure, anti-vibration pads and duct silencer to reduce noise emission;
- Burner is equipped with high-efficiency silencer and sound enclosure to effectively control noise;
- Bucket elevator, vibrating screen and other equipment generating noise are all covered with aluminum-silicate wool insulated steel panel, providing optimal energy efficiency and noise reduction;
