LIAD is proud to introduce PelletSave - a gravimetric central blending and feeding system Liad Weighing and Control Systems Ltd.
By means of a uniquely designed central mechanical dosing structure, combined with innovative control software, PelletSave is able to prepare the required weighed batch and to convey it separately to each of the plant's processing machine, according to each specific job requirement.
PelletSave Advantages:
• Significant saving in initial installation costs when compared to local dosing systems
• Up to 12 ingredients in each mixture and up to 50 processing machines (extruders, injection molding or extrusion blow molding machines)
• A complete solution for all procession machines, big and small, with one operation method for all
• High dosing accuracy and good blending while less expensive and more convenient for operation
• Sophisticated software controls the formulation, mixture preparation and designation
• No need for manual interference (opening/closing valves, changing hoses, cleaning residues of previous mixture etc.) when switching to new job with different mixture composite
• Easy and reliable central data collection for total consumed and wasted materials for each processing machine and specific job
• Mechanically simple and robust, with few moving parts compared to conventional systems
General Configuration:
The system is composed of the following sub-systems:
1. Raw material intermediate hoppers (bins) – one for each anticipated ingredient. These bins are automatically fed from raw material storage silos via a vacuum conveying system and loaders.
2. Central weighing, blending and feeding unit – prepares the required mixed batch for each specific machine and job.
3. Designation unit and mixed material buffer bins – a conveyor conveys the prepared mixture from the mixing chamber into the required buffer bins, one for each processing machine (injection or extrusion), from which the mixture is conveyed to the machine itself via a vacuum conveying system and loaders (supplied either by the customer or LIAD).
4. Central controller – controls the complete system operation, as well as collecting the data concerning the consumed materials and jobs.
