Features:

1. Control system: It adopts the latest generation of human-machine interface control and can be configured with a video industrial monitoring system to monitor the operating status of the equipment in real-time. The components are selected from internationally renowned control components to provide reliable quality assurance. The plant is simple to operate, stable and reliable, and technologically advanced. Full computer Chinese dynamic process interface, full-screen display, real-time monitoring, and alarm; operation starts according to the process, highly automated. The management system can integrate the resource advantages of the mixing plant, optimize and control each link of the production process, increase productivity, and reduce the consumption of energy (electricity, fuel) and other raw materials.

2. Mixing system: adopting European twin-shaft paddle mixing technology to realize large-circulation and three-dimensional mixing, so that the mixture can be uniformly stirred in a short time; wear-resistant blades and liners are made of chromium-molybdenum alloy wear-resistant cast iron; high-speed synchronization is adopted Organization, effectively reducing equipment maintenance links.

3. Weighing system: Asphalt weighing adopts coarse weighing and precise weighing technology, which has higher weighing accuracy; advanced full-computer automatic drop compensation function to ensure more accurate control of the metering system.

4. Combustion drying system: multiple options such as fuel oil, gas, fuel, etc. The drying drum is driven by an internationally well-known reducer, and it runs easily and freely; the material extraction blades are optimized for design, and the heat utilization rate is high; the outside of the drum is provided with an insulation layer to reduce heat loss; the drum discharge port is equipped with a temperature measurement device.

5. Cold aggregate supply system: The aggregate feeder adopts a 3+3 module combination form. Six-stage equipped with speed reducer frequency conversion speed regulation; the entrance of the bin is equipped with a screen and the size of the material door is adjustable. Two sand bins are equipped with silo wall vibrators to prevent material blocking.

6. Vibrating screen system: The international advanced five-layer vibrating screen is driven by dual motors and the excitation force is automatically coupled; the vibrating screen has a bypass bin structure that is more convenient to use and has the ability to efficiently and reliably respond to different types of ingredients.

7. Dust removal system: adopts two-stage dust removal design with one-stage gravity dust removal and two-stage bag filter; selected waterproof and oil-repellent Nomex knitted felt; adopts automatic wind pressure adjustment control system to ensure dust removal quality and environmental protection standards; There is an insulation layer on the outside of the bag filter to avoid condensation on the bag and reduce operating and maintenance costs.
