The Belt-Way ROLL-R Scale was specially designed for use on portable equipment such as rock crushers and screeners. The ROLL-R scale is extremely easy to install and gives the user the option to eliminate a dedicated conveyor for the belt scale. Crushers and screeners are very diverse, so Belt-Way designed the ROLL-R scale to be very flexible. It can be installed in between two idlers or be used in place of an existing idler, and there are three options that will fit almost any width conveyor. Please contact Belt-Way to confirm the ROLL-R is best suited for your application.
