Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two. The main differences that make up the majority of the cost differences is the drive configurations. Since the Double Roll Crusher is V-belt driven, lower motor horsepower can be used due to the flywheel design.
