What is the best speed for a belt sander?
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 .
How do I choose a sanding belt?
Choosing the Right Sanding Belt Grit The heavier the job, the coarser the sanding belt you’ll need. 40 to 60 grit is best suited for the heaviest work. When you’re performing tasks such as smoothing surfaces or removing minor blemishes, you’re better off using sandpaper with 80 to 120 grit.

A conveyor speed, or in this case the linear belt speed, can be calculated using the formula pi/2*D*RPM/60. In this formula, D is diameter and RPM is the rotations per minute of the conveyor. The value is then divided by 60 to convert the speed into distance per second.
How do I determine my belt speed?
Calculate the belt velocity by multiplying the circumference of the pulley by the speed of the pulley. For example, the drive pulley has a circumference of (Pi)(D2). This equals 2(Pi). The speed of the pulley is 1,800 rpm.
