Disc Pelletizers (Pan Pelletizers)

If lab tests reveal that alternative agglomeration methods such as briquetting or compaction is the method of choice, FEECO can accommodate these processes as well. If agglomeration with a disc pelletizer is the method of choice, further savings can be realized with lower investment, power consumption, and maintenance costs.Read more
