It is possible to change the speed of a conveyor by changing the sprocket size.
If the sprocket is part of a sprocket and chain reduction, we recommend only changing the size of the larger sprocket. Using a sprocket with more teeth will slow the conveyor down and add more torque at the belt (easier for the motor to pull). Using a sprocket with fewer teeth will speed the conveyor up and reduce the torque at the belt (harder for the motor to pull) If you are speeding your conveyor up it is possible to push outside of the power of your motor and cause the overload to trip or the belt to fail to turn. Call our main line if you need further assistance.
If the sprocket is a drive sprocket on a roller chain conveyor, then make sure you are changing both the left and the right-hand side to the same size to ensure the belt pulls correctly. Sizing up will cause a higher belt speed, but increase the load at the motor. Sizing down will cause a lower belt speed but decrease the load at the motor allowing for larger loads on the belt. Caution, sometimes the sprockets are already the smallest size recommended for that
