How to Match 890x686x73mm Screens to a VSM300 Primary Deck
Introduction: Matching an 890 x 686 x 73 mm screen to a VSM300 primary deck depends on the deck opening, frame depth, edge profile, and mesh already in service. The frame must drop into the rails, seal at the edges, and stay locked under a full mud return. The mesh decides what the screen separates. Both must be right before price or any other comparison matters. The 890x686x73mm fit on a VSM300 primary deck The three dimensions do separate jobs. The 890 mm and 686 mm define the footprint across the deck opening. The 73 mm is the frame depth that carries the screen into the deck structure. On a VSM300, the primary deck is the first screening stage, so it receives the full mud return from the flowline before any solids are removed. Screens in that position sit under the heaviest solids load. That is why the frame depth and edge must land exactly where the deck hardware expects them. A frame that is slightly too shallow will not lock down; one that is slightly too deep will not seat ag...
