Main Components of a Filter Press
To separate solids from liquids quickly and effectively, a filter press machine has a number of important parts that work together. Longone thinks about how long each part will last, how stable it will be under pressure, and how easy it will be to fix when it breaks.
Key Components Include：
- Frame: Provides structural strength and supports all operating parts.
- Filter Plates: Form the filtration chambers and determine cake thickness and efficiency.
- Filter Cloths: Essential for capturing solids and ensuring smooth filtration flow.
- Hydraulic System: Applies closing force to seal plates and maintain operating pressure.
- Piping & Manifold: Controls slurry feeding, filtrate discharge, and drainage paths.
