RELEVANT TECHNICAL ASPECTS
4®
� Manufacturing Steps
Relevant Technical Aspects
5®
� PolyolefinsPolyethylene (PE)
�Polypropylene (PP)
Relevant Technical Aspects
6®
� Some major pre-compounding Bulk MaterialProperties:– Particle Size including lumps, if any (Sieve Analysis)– Abrasiveness– Angles of internal/external friction– Angle of repose– Specific Density– Bulk Density: loose/vibrated– Cohesiveness– Increased temperature– Moisture Content– Flowability– Hardness
MEASURING-
INSTRUMENTS
Relevant Technical Aspects
7®
� Shipping from storage silos at upstream plant bymeans of:
– Bulk Shipping�Road Trucks/Road Containers�Trains�Ships
– 20-25 kg Bags– Big bags (Super Bags)– IBC Containers– Octabins– Bottles– Rolls
Relevant Technical Aspects
8®
� Any handling����Varying product properties
� Any transportation/shipping� Varying product properties� Least damage: by belt conveyor
� Large distance transportation of bulk products� Product degradation� Product attrition� Product segregation
Relevant Technical Aspects
9®
Examples of Segregation
� Filling/Emptying of silo’s– 3 Main Types:
1. Centered free fall filling
EMPTYINGFILLING
Same effect in case of excentric filling
•Heavier particles drop•down via the angle ofrepose
•Due to filling effects,•the larger particles will•pass the silo outlet first
10®
Examples of Segregation
� Filling/Emptying of silo’s– 3 Main Types (cont’d):
2. Lateral filling by means of a Pneumatic ConveyingSystem
EMPTYINGFILLINGHeavier particles willland at largerdistances from inlet
Segregationduring emptying
11®
Examples of Segregation
� Filling/Emptying of silo’s– 3 Main Types (cont’d):
3. Centric filling by means of a Pneumatic ConveyingSystem
EMPTYINGFILLING
Larger heavier particlesmainly get to the centreof the silo
Segregation duringemptying
12®
Examples of Segregation
� Consequences of segregation– (Re-)blending required– Flow problems in downstream process– Poor Final Product Quality
� Inhomogeneous sections– Excessive dust emission
� Dedusting (Filtration) Equipment Cost� Health/Environmental problems� Explosion Hazards

SYNERGY For SUCCESS IN RUSSIA
14®
� Your major interest– Low (T)otal (I)nvestment (C)ost�high profit/attractive consumer price�higher consumption�better sales figures
�Smart Project Execution saves:– Execution Time
– Total Investment Cost
Synergy ForSuccess in Russia
15®
� Your new (revamp-) projectMUST include:
– Optimal Process Selection
– Optimal split-up of project�Optimal Package Units
Synergy ForSuccess in Russia
Definition of Package Unit:
Integrated system consisting of more than one equipment part, and supplied by one Vendor only
16®
� Your new (revamp-) projectmay include:
– Bulk Material Handling– Compounding– Film/Sheet making– Pipe making– Casting applications– Blow molding applications– Fiber spinning etc....
– Logistics/Distribution
Synergy ForSuccess in Russia
17®
� Your new (revamp-) project (cont’d)– Why re-invent the wheel?
– Nowadays major Vendors have considerableDownstream Project Engineering Capacity and implementtheir expertise as routine actions for certain parts of projects� Easier integration of equipment and packages
from other Vendors
Synergy ForSuccess in Russia
18®
� Optimal Execution by all partiesinvolved:
– You, as producer– The licencor, if any– Engineering Company– Smart Package Vendors– Subcontractors
Synergy Forsuccess in Russia
19®
� Relation smart execution – sound engineering– Do not just hobby and try– Despite of calculations, always test:
Bulk Material Product/Compound Properties are crucial and mostlynot constant
– Good System (Interface) Definition by yourself, and/or by an Engineering Company
Synergy ForSuccess in Russia
20®
� Relation smart execution – sound engineering– Do not only pay attention to the Purchase Price of Package Units
and Equipment– Verify that your Vendor has well equipped Test Facilities– Your requirement seldom involve off-the-shelf design– Local Service a MUST– Use weigh factors prior to selecting the right Supplier
