solids Pneumatic Conveying SystemsHistoryIn 1970 H.J. Linder’s German patent DE-PS 2-122858 described a complete procedure for pneumatical plug conveyingfor the first time. It features an impulse valve which forms plugs and a secondary feed line with so called relay stationsto maintain the plugs and continue their transport without dispersing them.The innovative and key characteristics were and still are virtually infinite conveying methods and capacitiesno blockage at slow speeds and large loading (µ kg material/kg air, gas)slow, gentle conveying from approximately 0,5 m/secalmost nonwearing - even for extremely firm and abrasive bulk cargo e.g. silicon carbide or grinding materialhardly any grain destruction and minimal abrasion of supersensitive products e.g. spray granulateno decomposition with mixtures and processed masseslow energy costs due to an efficient use of the pressure energyreliable operating procedures even with damp, cohesive, sticky or poorly flowing bulk goodsFor about 40 years the solids solutions group has planned and built over 1000 systems based on this patent forthousands of different products in all European countries, the USA, Japan and India.TopicalityToday the solids solutions group offers nine well-engineered and tested systems using components assembled bythe company for the pressure- and vacuum-conveying.With 45 engineers and technicians as well as highly trained staff in assembly, installation and service we areobjectively able to offer the most advantageous system for every product and every task.solids Pneumatic Conveying Systems – The most advantegous system for every product and every taskFlow modeDescriptionsolids Fly PneuDilute phaseconveying classic dilutephase conveying systemfor suction- or pressureconveying.

solids Pneumatic Conveying SystemsAnalysis of bulk solidsFirst and foremost, an analysis of the bulk goods to be conveyed is required in order to choose the appropriateprocedures/systems and componentsGeldart divides the bulk cargos according to their fluidization behaviour and air retention into the groupsA, B, C, D, providing a rough classification of the conveying characteristicsABCDfine-grained powder with low density, easily fluidised with good air retentionmedium granulation with medium density, some fluidisation properties with poor air retentionfine powders with higher density, cohesive, poor fluidisation properties with poor air retentionlarger granulation with higher density, no fluidisation properties, no air retentionJenike describes the flowability of the bulk goods using the yield function FFC, providing a rough classification ofdischarge behaviour from tanks. His classification is:FreeflowFlowCohesiveVery cohesiveNon flow, hardening10 FFC 4 FFC 102 FFC 41 FFC 2FFC 1The conveying characteristics and the discharge behaviour from tanks are both relevant for the planning ofpneumatical plug conveying, and therefore must be included in the evaluation.Additionally the nature of the task and the specific requirements such as the maintenance of the productcharacteristics, granulation, volume, bulk weight, no contamination etc., have to be considered.Flow chartsProductexampleDescriptionGroup acc. toGeldartlime stone,cement, lime,PVCeasiliy fluidised,Group A: finegood air retention and / orlightweightsolids Fly Pneufluidised 10 FFC solids Fluid PneuViz. free flowingnot fluidised 2 FFC 4 solids Vacu Fillviz. cohesivesand, bottomash,granulatessome fluidisationproperties withpoor air retention4 FFC 10viz. flowingGroup B:granularitymiddle and / orheavysystem-technik GmbHLechwiesenstr. 21, 86899 Landsberg / LechTel. 0049 (0)8191-3359-0 / Fax 0049 (0)8191-3359-22info@solids-systems.de www.solids.deGroup acc. toJenikesolids conveyingsystemssolids Fly Pneusolids Step Pneusolids Vacu Densesolids Vacu Dense
