What types of used filter centrifuges are available?

What types of second-hand filter centrifuges are there? 1. Vibrating discharge centrifuge: The semi- conical angle of the drum wall is less than the friction angle between the filter cake and the filter mesh. In addition to rotation, the drum also performs an axial reciprocating motion at a frequency of 25 to 37 times per second. Under the combined action of centrifugal force and vibration force, the filter cake moves from the small end to the large end of the drum filter mesh surface while dewatering, and is discharged from the drum. This centrifuge operates continuously, has a high processing capacity, and is suitable for separating easily filterable suspensions with solid particles larger than 0.3 millimeters, such as coal particle dewatering, etc.

2. The swinging bucket centrifuge features a conical drum with an angle (0°-6°) between the drum's axis and the main shaft, rotating simultaneously around its own axis and the main shaft. The semi-meridian angle of the drum wall is less than the friction angle between the filter cake and the filter mesh. Under the influence of centrifugal force and the precession inertia force, the filter cake moves towards the larger end of the drum and is discharged. This centrifuge operates continuously, has a high processing capacity, and consumes less power, making it suitable for dewatering coarse-grained materials such as salt and synthetic resins.

3. Overhung Centrifuge: A vertical centrifuge with the drum suspended below the long main shaft. The main shaft's fulcrum is far from the drum, allowing the drum to automatically center during operation for smooth performance. The drum diameter ranges from 800 to 1350 millimeters and operates intermittently. The filtrate is discharged from the bottom of the drum, typically through gravity discharge, where the filter cake is expelled from the drum under its own weight when the drum speed is reduced or stopped, resulting in minimal particle breakage. Manual discharge or using a scraper mechanism with a scraper for discharge is also possible.
