SLHB-15 Type Double Drum Asphalt Concrete Mixing Plant
(1) Detailed Technical Description
The complete set of SLHB-15 mobile asphalt concrete mixing equipment developed by our factory includes: mineral material elevator, combustion furnace assembly, drying drum assembly, mixing drum assembly, hot asphalt metering and conveying device, stone powder metering and conveying device, finished product silo, primary tubular dust removal device, trailer chassis, traveling device, electrical control cabinet and other main components. The main machine adopts a trailer structure form in which the drying drum, mixing drum and intermediate material conveying device are integrated. The whole machine occupies a small area, has a short installation period for relocation and positioning, a wide range of fuel applicability, and features simple operation, convenient maintenance, stable and reliable performance, good quality of finished products, high technical content, and high levels of automation and standardization. It is particularly suitable for the construction and maintenance of high-grade asphalt pavement.
The specific performance characteristics of the SLHB-15 model are as follows:
1. The main unit can be towed and moved as a whole, and it is simple and convenient to install and position.
2. The support feet are adjusted hydraulically, which makes installation and adjustment effortless, time-saving, stable and reliable.
3. The components of the drying drum are made of 16Mn steel with a thickness of 16mm.
4. A first-stage cyclone dust collector is adopted, which has a relatively good dust removal effect.
5. The hot asphalt metering and conveying device adopts asphalt pumps for conveying and liquid level relays for metering, ensuring accurate oil-to-stone ratio.
6. The key components of the electrical control cabinet are all made of internationally renowned brand elements, including:
（1）.Buttons, contactors, motor starters, molded case circuit breakers, terminal blocks: Siemens;
（2）PLC programmable controller, programmable display, time relay: Mitsubishi.
7. The motor adopts a well-known domestic brand: Xiamen Motor.
8. The combustion furnace is a dual-purpose type for both coal and oil, equipped with an electronic automatic ignition device. The applicable fuel range includes diesel, heavy oil, residual oil and other combustible oils. The flame size can be directly adjusted in the control room to control the discharge temperature of the finished material, meeting different construction requirements. It has high thermal energy and low fuel consumption.
9. This equipment effectively overcomes the inherent defects of domestic straight-tube continuous stirring equipment, including:
⑴ Stone powder is prone to scattering.
⑵ Asphalt is prone to aging.
⑶ The continuous measurement accuracy of mineral materials and asphalt is difficult to guarantee;
⑷ The temperature of the mineral materials is not stable enough, etc.
