Modeling Based On Controlling Style：

Select intermittent type or continuous type by manufacturing technological flow . The first type usually use hopper or liquid container  ; the other one usually use belt scale or underweight style .

Selection of Specification Based on Production Output:

Hopper's weighting range is determined by size of mixer . Advice is to use two or three scales to solve the great disparity among many different materials .

Select Scale's Feeding Instrument ( Feeder ) and Relief Instrument ( Scale Gate ) according to the Status of Materials. 

Status of common materials are Powder , Grain , Sheet , Thread , Liquid or Starch . All these are different in Fluidity and Viscosity , thus it is necessary and much better to select corresponding Feeder ( belt feeder , screw conveyer / stranded conveyer , throttle gate , valve feeder , vibration styles ) and Reliefer ( wide-gate , draw-gate , inverse-gate , curve-gate , belt , stranded , vibration , valve styles ) according to materials status .

Design of Storage and Hopper  

Design of storage and hopper must be reasonable corresponding to materials with different fluidities . Some even need protecting devices . Only good design of storage and hopper can pledge the auto producing process , otherwise , materials often block up the machine and make it work in correctly . In that case , unsuitable design will increase troubles of self-dropping machine and reduce producing efficiency . Suggest users considering about this kind of design before they build up their manufactories , or it will effect on the whole project.

About Auto - Control Modeling

There are some types of auto-control batcher scales :(1)Single Board Computer Instrument：Simple and reliable , but not good at the unity of date .(2)Industrial Computer Controller.Use industrial controller to collect and process date . Nice man-machine interface and good feature of data statistics are good for on-line operation , specifically it has require high condition of fieldwork . In details , it requires good electric power , little dust , steady temperature in a certain range , high quality operators .(3)PLC Touching StyleFit for specialized batching system . It has friendly man-machine interface , convenient design procedure of parameter , high reliability . Except low ability of statistics , it still can interact with other machines .Fit for specialized burden system . It has friendly man-machine interface , convenient design procedure of parameter , high reliability . Except low ability of statistics , it still can interact with other machines .

Structure of Scale Body

There are two usual styles of scale body : The typical one is multi-sensor structure ( use three sensors ) . The structure is simple but difficult to judge faults . The other one use one sensor and specialized Force Transducer , thus force from any part of the scale hopper can be transfered to the same sensor . This style requires good machining , which only special design and manufactory can achieve . But to user , it is convenient to adjust and easy to replace worn parts .
