The standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50-pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.

Get Price### Motion of a box in a conveyor belt - Physics Stack Exchange

The conveyor belt rollers being pulled along by the belt interact with the belt via static friction as their outer surfaces move at the same speed as the belt. This static friction will not change since the rollers are the load. Only a pulley driving the belt (via a motor) will experience an increase in torque, and thus interaction friction, as the box is dropped onto the belt.
