Every post on this site ends with the same line: send us your drawings. Plenty of people stop there because they are not sure what counts as a drawing, whether what they have is good enough, or what comes back. This is the checklist our engineers work from when a conveyor layout drawing request arrives. Every layout decision, from belt width to incline to discharge arrangement, rests on one of these inputs; a missing input means a conservative guess that adds cost or an optimistic one that adds risk.
The Seven Things a Layout Depends On
The material, on its worst day: what the conveyor carries (cake, screenings, grit, lime-stabilized or dried product) and its wettest, stickiest, most abrasive case, with the dewatering method and any seasonal swings. Operator description beats nothing; a sample analysis beats both.
Throughput and schedule: peak tons per hour, not daily average, and whether the plant runs 24/7 or one shift. Continuous duty points toward the Model-H; planned expansion changes the sizing.
The route: where material enters (discharge lip height of the press or centrifuge), where it must end up (hopper top, trailer, storage pad), and what sits between: distances, rise, ceiling heights, openings, columns, tanks, pipe racks. The Pathwinder conveyor turns through a 6-foot radius and climbs at 45 degrees, so it can wrap around obstacles, but only if the engineer knows where they are.
Discharge requirements: one fixed point, or filling a trailer end to end, switching bays, feeding storage and loadout, rotating between dumpsters. Multiple destinations point toward a Flight Distribution conveyor; a discharge that moves within an arc without structural changes points toward a Flex-End Discharge. Deciding late means redesign.
Environment: indoor or outdoor, H2S exposure, washdown chemicals, freezing winters, odor control enclosure, electrical area classification. These set the materials of construction before the drawing starts, not after the bid.
Controls: local start/stop or sequenced with dewatering through SCADA, interlocks, any monitoring wanted. Serpentix designs controls with the mechanical system, so P&IDs or a control narrative help early.
Constraints that are not on any drawing: outage windows, whether an existing conveyor must keep running during install, funding source (federal money brings BABA requirements), crane access and the largest piece that fits through the door, seismic requirements, and where the maintenance crew wants platforms. Hendersonville is the example: a new Model-H had to integrate with a Serpentix conveyor installed in 1999, and that shaped the whole design.
What Drawings Help Most
In order: a plan view with pickup and discharge marked, a section showing floor and ceiling heights, equipment submittals for the dewatering units and anything at the discharge, and photos of the route. CAD is welcome, not required. A marked-up PDF of an old as-built or a dimensioned hand sketch has started many successful projects. What stalls a project is sending nothing because the drawings seemed too rough.
What Comes Back
The free engineering review is a working session. Serpentix engineers review the package, usually come back with questions, then produce a proposed layout showing route, incline, discharge arrangement, and preliminary equipment selection, with your regional representative in the loop throughout. Consulting engineers writing bid documents should put the same seven items in the spec as design data so every bidder designs to the same problem; our engineers will review a draft specification the same way.
Nobody has every item on day one. Gather what you have, note what you do not know, and submit your drawings for a free engineering review. A partial package with honest gaps beats a complete one built on guesses. Prefer to start in person? Find your regional representative.
