Between the ship arriving and the first saleable ton, there are four things that decide the schedule: foundations, packing discipline, installation quality and commissioning discipline. We support all four — and we promise guidance and acceptance testing, not plant management.
Installation starts in the factory, not on your site. Foundation and general-arrangement drawings are issued ahead of shipment so your civil works can run in parallel with manufacture rather than after it — the single largest schedule saving available on an overseas project.
Our engineers attend site to guide installation and supervise commissioning through to acceptance at rated capacity. How much attendance you need depends on your team and your site — some clients ask us to supervise the whole mechanical erection, others only want us present for alignment, belt tracking, electrical interlocks and the trial run. Both are workable; we agree the scope before you place the order so it is priced honestly.
Commissioning itself is a sequence, not an event: no-load rotation checks, lubrication system proving, interlock testing, dry run, load-up in stages, then trial run at rated capacity with product-size verification. We do not declare a line commissioned on the strength of one good hour.
| Step | What is checked | Who signs it off |
|---|---|---|
| Foundation acceptance | Anchor positions, level and grout condition against the foundation drawing | Client's civil contractor and our engineer |
| Mechanical erection & alignment | Crusher alignment, drive coupling, conveyor and screen installation, chute clearances | Our engineer with client's installation team |
| Lubrication & hydraulic proving | Oil levels, flows, pressures, temperature interlocks and alarm set points | Our engineer |
| Electrical & interlock testing | Motor rotation, starting sequence, emergency stops, interlocks between machines | Client's electrical contractor and our engineer |
| Dry run (no load) | Rotation, vibration, belt tracking, screen amplitude, control responses | Our engineer and client's maintenance lead |
| Load-up in stages | Feed rate increase with monitoring of power draw, temperatures and product samples | Our engineer |
| Trial run at rated capacity | Sustained throughput and product gradation against the agreed specification | Both parties — the acceptance record |
| Operator & maintenance training | Operating procedure, wear inspection routine, planned maintenance schedule, safe isolation | Our engineer, with attendance recorded |
Acceptance criteria are agreed in writing before commissioning starts, based on the capacity and product sizes in the configuration sheet. A criterion agreed afterwards is an argument; a criterion agreed beforehand is a contract.
The most common cause of a stalled installation. Which is why we issue foundation drawings before shipment — the civil works are the client's scope, and they need the data early.
An unstamped customs document holds the whole shipment. We supply the documentation set and assist through clearance, and we advise on inland leg transport to remote sites — the leg that most often exceeds expectation.
A 40-foot container of marked parts with a matching installation drawing is a one-week erection. An unmarked load is three. This is a packing discipline, and it is designed in.
If nobody wrote down what "working" means before the trial run, no result will be accepted. We agree capacity and product-size criteria in writing at configuration stage.
Tell us the destination port, your site conditions and how much of the erection your own team will handle. We will scope the attendance, issue the drawings early and give you a realistic site schedule.
