Asphalt Plants

Asphalt PlantsAn asphalt mixture plant is an assembly of mechanical and electronic equipments where aggregates, recycled materials or other additives are blended, heated, dried and mixed with binder to produce asphalt mixture meeting specified requirements. The plant may be stationary or portable. There are numerous types of plants, including batch plants, continuous mix plants, parallel-flow drum plants, counter flow drum plants, and double barrel drum plants to name a few. In general, however, the majority of plants may be categorized as either a batch plant or a drum mix plant.

 

The purpose of the burner inside the drum mixer is to provide the heat necessary to heat and dry the aggregates used in the final mix. The burners provide this heat by burning oil, gas, or pulverized coal. In all cases, the fuel feed and air blower are required to be balanced to ensure that the proper proportions of fuel and air are being introduced into the burner for efficient combustion. Lack of balance may lead to incomplete burning of the fuel, which, especially in the case of fuel oil or diesel fuel, may leave an oily coating on the aggregate particles. Our burners can regulate fuel feed and air flow for complete combustion to correct such imbalances.
