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 [metric] 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 specialized plastic materials.

Plastics 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 plasticized in the extruder under highpressure and high temperature and modified in a physicalmixing process. The granulator at the extruder dischargecuts the plastic strand into granular form with remarkableperformance. Large granular plants operate at a feed rateof up to 40 t/h and higher.

Our Solutions PackageDay 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.

Free to poor 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 free to extremely poor flowing additives.Free to moderately flowing additives are fed with theMechaTron® Coni-Flex® single-shaft feeder.Poor flowing additives can be fed with MechaTron®

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

Advantages

High feeding accuracy – better than ±0.5%High feeding constancy – 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 designVirtually maintenance-freeLow construction heightReduced investment due to MechaTronic solutionEasy integration into the production processProcess reliability due to individual tests in our bulksolids lab

The enhancement of standard plastics (PE, PP, PA, ABS, SAN) with additives for customizedapplication of plastic materials places extreme demands on the plastic mixer/compounder andrequires high flexibility. Mixing takes place during a highly viscous melting phase, which is onlypossible with a specially matched mixing tool. The mass flow rates in the compounder liesbetween several hundred kg/h [metric] up to 10 t/h [metric].

The short-time feeding constancy is critical in the case of mega-compounders with speedsof up to 1,000 rpm. Above all, the high reliability and accuracy of the Schenck Process feedingunits ensures the required product quality.

Plastics 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 an inlet funnelHorizontally via a lateral feeder, which conveys intothe meltFibers (glass fibers, coal fibers)Other additivesLiquids (cross-linking agents, lubricants)Highly abrasive glass fibers must be directly fed intothe melt.Liquids are added directly along the compounderhousing by means of an injection needle.
