Why do belt sanders use more energy than disc sanders? Read on to learn more. 

We’ve staked our claim to fame on our incredibly low operating costs, and in all of our cost of operation worksheets we discuss how much more expensive wide belt grinding machines are to run when compared to a Loewer DiscMaster.  It’s worth understanding how the machinery works and why conventional machinery uses so much more electricity.

There are three primary factors that contribute to energy consumption; Mechanical friction from moving parts like chains, rollers, wheels, bearings and belts; friction between the abrasive belt and the part surface; and heat generated through the manipulation of the belt (which can be significant in some instances).  Larger machines with more bearing surfaces and heavier parts create more mechanical friction.
