Belt weighing scales are selected when an accurate weighing of product flow of all kind of bulk material is requested.
The weight of a belt section acts directly to a load cell by means of a weighing brigde. Analogue to the weight the load cell transfers a measuring signal to the build-in electronic analysis device for evaluating the data. The flow rate as integral of the feeding rate is determined by the associated belt length. The encoder is driven by a friction wheel which is moved from the bypassing bulk or via a joint coupling driven by the tail pully of the conveyer.
Execution as single-roller or multi-roller
Several standard- and statistic functions
Belt width: 400 - 2.000 mm
Capacity: 25 - 4.000 t/h
Single-roller belt weighing scale at belt speed: < 2,5 m/s
Multiple-roller belt weighing scale at belt speed: > 2,5 m/s
Accuracy of measurement:*): 0,5 %
*) the JÖST® installation instructions must be observed
Guaranteed accurate and continuous measurement of bulk material
The evaluation device can be combined with all programmable logic controllers (PLC)
