Heating system of asphalt concrete mixing plant

The heating system of asphalt concrete mixing plant functions to dry and heat up aggregates to help them mix successively with asphalt. The aggregates first move in the drying cylinder and get evenly heated to achieve drying. Then the aggregates continue to be heated, the temperature is detected by the infrared thermometer, the regulator processes the detection results, and the fuel supply and wind of the burner are adjusted by the servo motor to achieve the lowest fuel consumption and the best heating effect.

The drying and heating system of an asphalt mixing plant mainly includes a drying drum and a combustion device. The drying drum is a device for drying and heating cold and wet aggregates. The liner of the drying cylinder of our company is welded by HARDOX (www.ssab.com) imported Swedish steel on the fully automatic welding platform of the drying cylinder, and the welding surface is smooth and even. The combustion device is mainly a burner. Its function is to provide a heat source for the drying cylinder and cold and wet aggregates. Therefore, in addition to choosing the right fuel, it is also necessary to choose a suitable burner for the asphalt mixing plant. The combination of the burner and the drying drum can make the cold and wet aggregate complete the three steps of preheating, dehydration and drying, and heating and heating in a limited time, and meet the technical requirements. This not only requires the aggregate to be evenly distributed in the drum, but also requires sufficient running time for it. The company's heat treatment equipment fully meets this requirement. Heat treatment equipment such as resistance furnace and high frequency furnace heat the gears, the stirring shaft of the stirring tank, and the steel parts to increase its performance, make it more wear-resistant and durable, and increase the service life. In addition, in order to ensure the heating effect of the asphalt mixing plant, in addition to the reasonable selection of the above-mentioned two devices, certain heat preservation measures need to be taken.

The heating system of asphalt concrete mixing plant includes a light/heavy oil dual-purpose mechanical atomizing burner (optional), an automatic flameout protection device, valves and fuel pipes, burner platform and guardrail ladder, light oil tank and pipeline (optional), light oil tank (optional), heavy oil tank (optional), gas burner and automatic flameout protection device. The price of the system depends on the devices you need. Welcome to contact us for a price!
