The burners of asphalt mixing plants are divided into pressure atomization, medium atomization and rotary cup atomization according to the atomization method. Pressure atomization has the characteristics of uniform atomization, simple operation, less consumables, and low cost. At present, most road construction machinery adopts this atomization type.

Medium atomization refers to premixing with fuel and then burning it to the periphery of the nozzle through 5 to 8 kilograms of compressed air or pressurized steam pressure. It is characterized by low fuel requirements, but many consumables and high costs. At present, this type of machine is rarely used in the road construction machinery industry. Rotary cup atomization is where fuel is atomized by a high-speed rotating cup and disk. Can burn poor quality oil, such as high viscosity residual oil. However, the model is expensive, the rotor plate is easy to wear, and the debugging requirements are high. At present, this type of machine is basically not used in the road construction machinery industry.

According to the machine structure, the burners of asphalt mixing plants can be divided into integral gun type and split gun type. The integrated machine gun consists of a fan motor, oil pump, chassis and other control elements. It is characterized by small size and small adjustment ratio, generally 1:2.5. High-voltage electronic ignition systems are mostly used, which have lower costs, but have higher requirements on fuel quality and environment. This type of equipment can be used for equipment with a displacement of less than 120 tons/hour and diesel fuel.

The split machine gun divides the main engine, fan, oil pump unit and control components into four independent mechanisms. It is characterized by large size, high output power, gas ignition system, large adjustment, generally 1:4~1:6, or even as high as 1:10, low noise, and low requirements for fuel quality and environment.
