In a loss-in-weight batching system, the bulk bag discharger and often the entire conveyor/feeder is mounted on a scale.
An advantage to loss-in-weight batching is that multiple ingredients can be simultaneously discharged into the process, reducing batch creation time.
Also, the complexity of the batching routine required will affect the associated software and hardware requirements.
If your process requires batching accuracy better than [+ or -] 1 lb.
The pelletizing must guarantee a grain hardness which enables it to surpass stresses from conveying and batching, but must allow for compounding and easy dispersion in the batch.
Batching - use of fluidized air-slides and specially designed weighing heads allows for fast, clean and precise batching.
All these devices are applied in order to guarantee the repeatability of all batching operations independently of climatic and environmental conditions.
It also provides for transfer to dally tanks and from these to the batching systems, one for each mixer, and to the eventual feeding tanks of the mixers dust stop rings.
