Quzhou Horbon Mining Parts Co., Ltd. is one of the leading manufacturers and suppliers of vertical shaft impactor upper frame in China. With abundant experience, we are committed to providing high quality customized service and OEM service to global clients. Welcome to buy advanced vertical shaft impactor upper frame made in China here from our factory. Contact us for quotation.
What This Frame Does
On a vertical shaft impactor, the upper frame is the octagonal shell sitting above the rotor - it takes the incoming feed, houses the storage tank and feed gate, and shields the crushing chamber underneath. Bolted to it is a separate mechanism: the lifting device, which tilts the whole frame open on a hinge so technicians can reach the rotor without dismantling the machine.
Horbon builds both as a matched Vertical Shaft Impactor Upper Frame set for the VSI4000, referencing original part codes for each component.
Sourcing From Horbon
Two things separate a factory-direct order from a distributor one: traceability and turnaround.
Every part code in our tables below (3103030071, 3103030101, etc.) maps to the original numbering, so what arrives matches what's listed - no field verification needed on your end. If you don't have a part number at all, send a photo or the worn piece itself; our engineering team measures it and returns an initial 2D/3D drawing in roughly 3 days, then produces from that model.
Batches go through spectral material checks, HRC hardness testing, CMM dimensional measurement, and flaw detection before shipping, with third-party inspection arranged on request if your import process requires it. We don't hold formal certifications yet - this in-process testing is what stands in for that today.
Orders start at 5 units, so a first-time buyer can test fit and quality before committing to a container load. Branding (laser-marked logos) and export-grade packaging (fumigated crates or steel frames) are available for private-label or long-haul shipments.

Questions Buyers Usually Ask
Q: Does the upper frame fit my machine if I only know it's a VSI4000?
A: Yes - the part codes above are matched to VSI4000. If your unit is a different brand or a modified VSI4000, send a photo or part number first and we'll check before quoting.
Q: We have a broken part but no drawing - is that a problem?
A: No. Ship us the damaged piece; we rebuild it as a model and produce from that, no original drawing required.
Q: How fast do you turn around a drawing once we send the sample?
A: Around 3 days for the first version, before production even starts.
Q: What stops a bad batch from shipping?
A: Spectral testing on the raw material, hardness checks, dimensional measurement on CMM, and flaw detection - done per batch, with outside inspection available if your customs process asks for it.
Q: You don't list ISO or CE - how do we trust the quality then?
A: We're honest that we don't hold formal certifications yet. What we rely on instead is the batch-level testing above, plus free replacement if something's wrong on arrival.
Q: Can we order less than a full container to test you out first?
A: Yes, 5 pieces is the minimum - enough to check fit and finish before a larger order.
Q: Do you put our logo on the parts?
A: Yes, laser marking is available for OEM/private-label orders.
Q: How is it packed for ocean freight?
A: Fumigated wooden crates or steel frames, chosen based on part size and your route.
Q: What if something arrives wrong or defective?
A: We replace it at no cost once the issue is confirmed, and provide installation guidance alongside it.
Q: What are your shipping terms and ports?
A: FOB or CIF, loading from Shanghai or Ningbo - compatible with your own forwarder.
