Aggregate is one of the main components of concrete. It mainly plays the role of skeleton and reduces the volume change caused by shrinkage and swelling of cementitious materials during the setting and hardening process. It also serves as a cheap filler for cementitious materials. There are natural aggregates and artificial aggregates. The former include crushed stone, pebbles, pumice, natural sand, etc.; the latter include coal slag, slag, ceramsite, expanded perlite, etc. Aggregate drying is useful to ensure the performance of concrete, improve the quality of mortar, prevent caking and deterioration, and facilitate transportation.

  Aggregate drying requires an aggregate dryer, the most common of which is a drum dryer, which consists of a drying drum, a heat source device, a conveying device, a screener, etc. After the aggregate enters the drying drum from the feed end, the aggregate continues to roll and move forward in the drum as the drum rotates slowly. In this process, the aggregate is fully in contact with the hot air flow introduced from the heat source device, and the hot air flow transfers heat to the aggregate, causing the moisture in the aggregate to evaporate, thereby achieving the purpose of drying.
