First，the cold aggregate, asphalt and mineral filler are weighed respectively. The batch mix plant process begins when the aggregates is placed in appropriate bins of the aggregate feeders. The aggregates are then transferred to the drying drum by means of a conveyor. Drying drum is equipped with flights internally to promote drying efficiency. Once the aggregates leave the dryer, they are transferred to vibratory screen which does the task of separation of aggregates according to the size and the aggregates are dropped into the separate hot bins.
Cold Mixing Asphalt Plant . Cold mix asphalt is a combination of mineral aggregate and emulsified or cutback asphalt with additives. Aggregates can be made with virgin materials or reclaimed asphalt pavement, also known as asphalt millings. The latter option is commonly used when trying to save money. Cold mixes can be made on site or at a central location and then transported to the site. The flexibility to create this type of asphalt off-site is particularly useful for remote roads.
