With its automatic active torque control (ATC) for CF decanter centrifuges, GEA makes production processes more reliable under stick-slip conditions. GEA’s ATC solution features on-the-fly, automated correction of the differential speed by means of active torque control to ensure an optimal working point while avoiding stick-slip. This ensures maximum solid yield, minimum energy costs for thermal drying and significantly lower risk of system damage due to stick-slip.
ATC reliably detects the occurrence of the stick-slip effect and makes the necessary adjustment.
A perennial problem for decanter operators is finding the optimal working point to maximise dry substance yield while still avoiding stick-slip. Adding to the challenge is the fact that – like for products such as starch or casein – the optimal working point often approaches conditions where stick-slip can occur. GEA’s ATC solution adds intelligence to the decanter system so it can make the necessary adjustments on the fly for an optimal working point with optimal safety and efficiency. GEA offers its ATC automated monitoring and control system in new CF decanter series machines, as well as the option of retrofitting existing CF decanters with ATC.
