Roller GrinderIFAIowa Farm Automation

The key difference between a roller-grinder and a roller-mill is that a roller-grinder has the ability to run each roll in a set at a different speed. This differential between the speed of the rolls creates a grinding action that is desirable for many applications. Roller-Grinder Features Heavy-duty construction.
