Horizontal and vertical peeler centrifuges are the most versatile and reliable machines if it is about mechanical separation processes. The task for one or the other machine type is the same – but there are important parameters that have an impact on the decision for either the vertical or the horizontal peeler centrifuge.
Important criteria for the selection of a horizontal or a vertical peeler centrifuge can be divided into three categories: installation, process, economy.
Talking about the installation it is important to know whether it will be a brand new installation or a replacement of existing equipment. If just a replacement is planned, normally the process connections (feed pipe, wash pipe, filtrate pipe as well as the solids discharge mechanism) can be kept more or less “as is”. If a change of machine type from vertical to horizontal or vice versa shall be done, all connections to and from the machine need to be modified and replaced as well. This will have an impact on the project costs for both engineering and installation.
All process connections for the vertical peeler centrifuge are installed on the top cover, whereas the process connections for the horizontal peeler centrifuge are located at the front door. Due to the top cover opening, the vertical peeler centrifuge requires a larger room height, the horizontal peeler centrifuge has a larger foot print. The installation costs for the horizontal peeler centrifuge are lower in terms of solids discharge, because the solids discharge can be done on the same floor level as where the machine is installed. The bottom discharge of the vertical centrifuge is mainly effected at the level below the machine.
