Who we are, how we inspect every machine, and what our buyers say.

About Yangtian Machinery

A Chinese exporter you buy from directly

Yangtian Machinery is based in China (Yunnan) Pilot Free Trade Zone — China's mining-machinery hub. We sell directly: every machine on this site is our own stock, bought in, torn down, inspected and refurbished by our own engineers in our own workshop. Each unit carries a full source and service record — no rebuilt wrecks, no accident machines.

Overseas buyers can visit our Yunnan FTZ yard, join a live video inspection, or appoint SGS / BV for a pre-shipment inspection. We handle export packing, container loading, customs and sea freight, and keep supplying wear parts and remote after-sales support after delivery.

Inspection Standard

Inspection standard

Each equipment type has different weak points. Pick a type to see what our own engineers must check before a unit is cleared for export, and the pass marks.

Crushing equipment — inspection points

Crushers hide damage well: chamber cracks, main-shaft wear and swapped liners. We measure each item and record it in the report.

Chamber & frameDye-penetrant check — no cracks, no repair welds

Liners & blow barsRemaining thickness measured and photographed

Main shaft & bearingsRunout and clearance measured; no-load test run, listen for noise

Hydraulics / lubricationStable pressure, no leaks, oil sampled

Motor & controlsInsulation resistance measured, full-load current recorded

Hour meter & recordsService history and wear-part replacements verified

Liner life left≥ 50%Below this line the grade drops

Main shaft runout≤ 0.05 mmOver the limit — not cleared for export

No-load test run≥ 30 minAny abnormal noise — sent back for re-check

Buyer Stories

What overseas buyers say

Sample testimonials below — replace with real overseas customer feedback before launch.

★★★★★

“The jaw crusher arrived by sea in good order — liner wear matched the inspection report exactly. Buying direct from the factory saved us over $28,000 versus new, with no loss in output.”

DDmitri K.Kazakhstan · 300 t/h aggregate plant

★★★★★

“We confirmed the mobile plant on a live video test run with material before paying the deposit. At our site it was producing within half a day of commissioning.”

AAndi P.Indonesia · Construction waste project

★★★★★

“Four months in, the ball mill's main bearing started making a noise. Their engineers diagnosed it by video the same day and air-freighted the warranty part. That is what gives you confidence.”
