Concrete batching plant working principle and standards of control

Concrete batching plant working principle:
Concrete batching plant can be divided four parts:sand feeding,powder feeding,water and additive feeding,transmission mixing,storage. the concrete mixer control systems on, into the operator interface and machine dialogue system initialization process, including the recipe number, concrete grade slump, producers amount.
Weighing, measurement of the positions of various ingredients bucket detection output of material empty or material full signal, prompted the operator to determine whether to start stirring control program start sand, stone belt motor weighing hopper fed; open fly ash, cement tank, butterfly valve, start spiral machine motor transport pulverized co alto to open metering Dou doors gray cement to the weighing hopper; open the control valve of the water storage and admixtures pool water and additives into the weighing hopper. metering to meet the set requirements, stirred mixed ingredients into the concrete mixer started to set the time to open the mixer door, and concrete mixer truck had then expected.
Concrete batching plants standards of control;
1.Each of the cylinders, control valves and motors concrete mixing stations stirring processes required to run each of the cylinders, control valves and motor control must be accurate, stable and reliable;
2.Control system with automatic or manual mode, and the relationship between independent constraints;
3.Alarm system has a good anti-interference ability and perfect self-protection;
4.Communication with the computer, you can display system status, fault alarm.
