Different machines to meet all needs
As hot aggregate leaves the dryer, it drops into a bucket elevator and is transferred to a set of vibrating screens that drops the aggregate into individual hot bins according to size. To control aggregate size distribution in the final batch mix, the operator opens various hot bins over a weigh hopper until the desired mix and weight for individual components are obtained. Recycled asphalt ...
