So, the capacity of the conveyor in 5 minute is ((50*5)/25) * 2. ie, 20 nos. So the capacity of this particular conveyor is 20 parts in 5 minutes or it will move 1 part in 15 Seconds. Hence the formula for the conveyor capacity is,((conveyor speed * time)/(length of part)) * no of parts along width of conveyor.
The first step in sizing a screw conveyor is to determine the diameter. The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are ...
