Flat Belt Conveyor Calculations

When it comes to setting up a flat belt conveyor, the devil is in the details—or in this case, the calculations. Getting these right ensures your conveyor not only fits perfectly into your workflow but also operates efficiently. The basic calculations for a flat belt conveyor system revolve around determining the conveyor length, belt speed, and load per foot.

Suppose you need to design a conveyor system to transport boxes in a packaging facility. Each box weighs 50 kg, and the goal is to transport 400 boxes per hour. The conveyor should span a distance of 50 meters between the centers of two pulleys.

Step 1: Calculate Belt Speed

First, you need to determine the speed at which the belt should move to handle the required number of boxes per hour.

Let’s calculate the belt speed required to meet the throughput:

  • Throughput requirement: 400 boxes/hour
  • Conveyor length: 50 meters

Assuming it takes about 30 seconds for each box to travel from the loading point to the unloading point, the speed of the conveyor belt can be calculated as follows:

  • Time to cover 50 meters = 30 seconds (0.5 minutes)
  • Belt speed (V) = Distance / Time = 50 meters / 0.5 minutes = 100 meters/minute

Step 2: Load Per Foot Calculation

Next, you need to estimate the load per foot to determine if the conveyor design is adequate for the weight it needs to carry.

  • Weight per box: 50 kg
  • Total weight handled per minute: (400 boxes/hour) * (50 kg/box) / 60 minutes = 333.33 kg/minute

To find the load per meter (since the system is metric):

  • Total weight per minute = 333.33 kg/minute
  • Conveyor length = 50 meters
  • Load per meter = 333.33 kg/minute / 50 meters = 6.67 kg/meter

Step 3: Check Belt Load Capacity

Finally, ensure that the conveyor belt you select can handle at least 6.67 kg per meter. If the maximum capacity per meter of the belt is higher than this value, your conveyor is feasible; if not, you need a stronger belt or additional design changes.
