what impacts the energy efficiency of conveyor systems?

As you can imagine, the greater the load and length, the more energy is required. A recent study showed that the belt conveyor is responsible for about 90% of the system's total energy consumption in a process with a variable material flow rate. In comparison, the system's motor accounts for just about 10%. It is, however, essential to consider ...
