Abstract

Mechanical filtration of solid/liquid phases using Pusher centrifuge has been a prevalent operation in industry. The purpose of the current study is the functional and structural analysis of the two-stage Pusher centrifuge dynamic performance. In this regard, modal, particle behavior scatter, and transient state Dynamic analysis have been considered. The results have revealed a safety margin of 40% for resonance plausibility for the entire set and inner basket subset due to the internal linear and rotary forces. In addition, based on the results of the transient dynamics analysis, the stability of particle behavior has been about 5.5 s or 68% of the particle feeding time, the maximum displacement at the critical point of the inner basket subset was 1.3 mm, and the critical stress on it was about 70 MPa. In overall, it has been recommended to keep the rotational speed as it is (36.68 rad/s), together with the same feed rate as specified (0.56 kg/s).
