Kreisel commissions a Ceramic Rotary Feeder at PPC Hercules

Kreisel reports on the benefits of the KREISEL Ceramic Rotary Feeder ZSV-H towards the screw pumps and on the successful commissioning of a ZSV-H at PPC’s Hercules plant.

The transport of the fine bulk solids, such as cement, raw meal, fly ash or coal takes place via complicated conveying line routings pneumatically. This means that the bulk solid is transported with conveying air through a piping line system. The occurring friction between bulk solid and the piping line wall, and the vertical lift of the bulk solid in vertical extending conveying lines create a pressure loss of the conveying air. Consequently, the conveying air must be provided for the product transport conveying air with a plant-specific pressure. Against this plant pressure, the bulk solid must be fed into the air flow of the conveying line. For this purpose different feeding systems are applicable.

In the past, pressure vessel systems or screw pumps were used for this purpose. For more than half a decade now, German company KREISEL GmbH & Co. KG came up with a solution to replace these systems with a highly wear-resistant Ceramic rotary feeder type ZSV-H. The most important criterion in using the KREISEL Ceramic rotary feeder is the energy saving during plant operation and considerable wear resistance of the components.

PPC operates various pneumatic conveying systems at the Hercules plant. Two of them are used to transport cement from the grinding mill to the receiving silo. The feeding of the cement in the conveying lines was carried out by screw pumps. Repeated disturbances, capacity losses and high energy consumption gave PPC enough reasons to bring about a technical change… read more on
