ROTARY DRUM DRYERS & COOLERS. As a wet process, pelletizing typically requires a drying step. This is frequently carried out in a rotary dryer, a high-capacity dryer that utilizes a cascading motion to dry pellets, while also rounding and polishing them as they tumble through the drum.In some cases, a rotary cooler may follow the dryer to cool material prior to packaging or storage.
