Refers to a variety of materials were in the same weighing bucket were successively measured by the measuring instrument to set each type of material value of the order with meter, Concrete mixing plants the same scales, said first pound of beans in the said half a catty of rice the same.
Divide
Dosing time, 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 material reaches 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)
Tare (zero)
Any measuring instruments are based on ready mix concrete plant the initial reference point measurement, the reference point can be temporal scales when the zero-value point, it can be empty scale time zero data points (such as the hopper a residual material or accumulated measured the former type of material the actual value), this non-zero data points can be controlled via the instrument manually or automatically considered next measured zero (initial reference point)
