the optimal speed for belt grinders is largely dependent on a number of factors, including type of abrasive grain, grit grade, workpiece material, and more. generally speaking, a safe speed in most cases is 3,000 surface feet per minute. you can calculate surface feet per minute using the formula sfpm = rpm x .262 x tool diameter.
one of the main reasons for having variable speed is to slow the belt down when using small wheels. a fixed speed grinder will do many things well, especially if the belt is moving at 3000 surface feet per minute or more. so if you don't have a small wheel set, then go for a direct drive fixed speed setup that generates adequate belt speed
