A flat belt without braces and carriers offers higher precision of measurement than a troughed belt. The flow rate of the belt conveyor is the product of the belt load (kg/m) and the belt speed (m/s). The speed of belt is measured by high-precision rotary encoders. These have a typical nominal frequency of 500 to 1000 pulses/rotation.

How Belt Feeders Work. A belt feeder consists of a hopper positioned directly over a belt conveyor. The belt conveyor "pulls" material out from under the hopper, while an adjustable vertical strike-off plate controls the height of material allowed to advance as the belt moves forward, or in other words, the material profile on the belt.
Loss-in-weight feeders consist of a hopper with a dosing unit, typically a screw or vibrating unit, all placed on load cells monitoring the material output of the hopper during dosing. Dosing is measured in kilograms per hour and the controller adjusts the speed of the dosing unit to match the setpoint, ensuring consistent product flow.
