Concrete batching machine measured

Wheel Loader, the electrical control signal is issued to stop dosing instructions to the materials actually fall weighing hopper during the set value (amount in advance) and the actual value of the difference, so batching machine at work by a control instrument in the concrete block machine the actual value of the advance a stop signal, the signal after the fall of this part of the material called gap.
Namely: the actual number - set number = gap (this gap batching machine instrument can automatically correct)
