Whether plastic bags or plastic molding for cars – plastics today varye.g. with respect to strength and durability. This difference is achievedin plastics granulation plants based on common plastics, such as PEor PP, and supplementing them with additives.

The MULTICOR® S masters the basic components and MechaTron®

the additives. Schenck Process equipment has the highest performance(>40 t/h) with the highest feeding accuracy.

An end product, such as plastic bags, is thus produced from an inter-mediate product. Or a product that is modified in additional processingsteps for even more specialised plastic materials.

Plastic GranulationFrom basic plastic materials to raw materialsfor successful end products – perfectly fed

The proven DISOCONT® measuring and controlelectronics permit easy integration in the productionprocess.

The powder is plasticised in the extruder under highpressure at high temperatures and modified in a physicalmixing process. The granulator at the extruder dischargecuts the plastic strand into granular form with remarkableperformance. Large granulation systems operate at a feedrate of more than 40 t/h.

Our scope of supplyDay bins for the basic plastic material and various additivesFillers and feeders from the storage containers intothe weighfeedersWeighfeeders for the variousproductsTransfer device from the weighfeeders into the extruder

With MULTICOR® feeding systems, basic plastic powders(e.g., PE, PP) and additives (carbon black, titanium dioxide,etc.) are fed into the extruder directly or via a continuousmixer by means of the MechaTron® loss-in-weight feeders.

Freely to poorly flowing additives, perfectly fedAdditives are fed with the MechaTron® or theMULTIGRAV® loss-in-weight feeders. Integral part ofthe MechaTron® system are the weigher configurationsfor feeding freely to poorly flowing additives.Freely to moderately flowing additives are fed with theMechaTron® Coni-Flex® single-shaft feeder.Poorly flowing additives can be fed with MechaTron®

Coni-Steel® double-shaft feeders.Liquids are fed with special liquid feeders.Simple, freely flowing products can be directly addedvia slide valves or butterfly valves.Poorly flowing additives can be added by means of fillingdevices, such as filling screws, vibratory trays, or agitators.

Advantages

High feed accuracy – better than ±0.5%High feed consistency – better than ±0.5%Feeding of various additives with a single weighfeedersystemEnclosed system – plant operation suitable for inertgas blanket (inert gas N2)Optional dust-proof or gas-explosion-proof design (ATEX)Virtually maintenance-freeLow installion heightLow cost due to MechaTronic solutionEasy integration into the production processProcess reliability due to individual tests in ourTestCenter

The enhancement of standard plastics (PE, PP, PA, ABS, SAN) with additives for customisedapplication of plastic materials places high demands on the plastic mixer/compounder andrequires high flexibility. Mixing takes place during a highly viscous melting phase and is onlypossible with a special mixing tool. The throughput volume in the compounder is betweenseveral hundred kg/h and 10 t/h.

The short-time feed consistency is critical for mega-compounders with speeds of up to 1,000 rpm.Above all, the high reliability and accuracy of the Schenck Process feeding systems ensure therequired product quality.

Plastic CompoundingFeeding with a system: highly accurate, highly constant –ready for each change of product

Material may be fed into the compounder invarious ways:

Vertically by means of a feed hopperHorizontally via a lateral feeder, which conveys intothe meltFibres (glass fibres, coal fibres)Other additivesLiquids (cross-linking agents, lubricants)Highly abrasive glass fibres must be directly fed intothe melt.Liquids are added directly on the compounder housingby means of injection.
