Lean phase conveying systems are used for decades for the transport of bulk materials. Is a minimal product attrition or the bulk density of importance, Gericke uses dense current phase systems. Dense phase means, that the loading of the piping with the material to be transported, is higher compared with a lean phase conveying system. In order to reach this, the product is brought not by means of a rotary valve, but by means of a pressure vessel, into the piping. Advantages of this technology are: high loading (small need of conveying gas), small conveying speed, which leads to reduced product destruction and thus controlled bulk density, deep conveying speed, small cleaning expenditure of the pressure vessels and automatic operation. For high conveying capacities and very gentle transportation, Gericke has developed its double-sender technology. The pressure vessels are alternatingly filled and emptied. A particular control algorithm prevents the occurrence of undesired product acceleration at the end of an emptying cycle.
