Equipment for PET bottling
Koch-Technik will be exhibiting equipment for PET bottling with the volumetric dosing unit KEM and the patented gravimetric dosing and weighing system with mixer Graviko (GK 250).
KEM: Chamber volume dosing (Kochpatent) with ± 0.15% accuracy for pellets, powder & ground materials: Each chamber of the dosing roll is filled evenly before it is discharged. The constant speed guarantees a high dosing accuracy. Benefits & features are the 5 dosing rollers for shot weights from 2 g to 10,000 g, an easier role replacement and a high dosing accuracy. Koch dosing unit types Kö (granules), Pu (powder) and Ma (ground materials) are stated to dose with high recipe accuracy. A large selection of pre-mixers with agitators guarantees a homogeneous premix. The modular dosing and mixing units for injection moulding, blow moulding and extrusion are designed to be adaptable and exchangeable with relevant Koch system conveyors. Benefits & features are an up to 500 kg/h machine throughput, a basic body made of GAL / So-HB 100 or V2A stainless steel and dosing via chamber volume.
Patented gravimetric dosing and weighing system with mixer
The patented Graviko system dispenses plastic materials reliably and with the highest repeatable accuracy using precision slides. One can choose from Graviko units with throughputs of 80, 250, 600, 800, 1,000, 1,500 and 2,000 kg/h. The system allows the user to easily dose & weigh, check, modify and evaluate the material in a single operation. The controller recognises external interference during weighing and compensates for it. A horizontal agitator ensures optimum pre-mixing. Benefits & features are a dosing using precision slides; Precise dosing & weighing, checking, correcting and evaluating – in one operation; interferences are immediately recognised and compensated; easy material change through sliding and swivelling features.
