The use and amount of recycled powder are limited by the road construction technical specifications. Except for a part of the use, the rest of the recycled powder Discard. Throw away. There are mainly two ways to deal with the recycled powder in the existing asphalt concrete mixing plants in China. One is to send the mineral dust collected by the dust removal system directly into the humidifier, discharge it into the pool after humidification, and load it with a forklift. This treatment method is more environmentally friendly, but all the recycled powder is thrown away, causing some waste. The other is to transport the mineral dust collected by the dust removal system to the storage tank through pipeline blowing.
