Ball Mill Procurement from China
Grinding Mill Specification & Inspection
A grinding mill is a long-lead machine where shell, liners, trunnions and girth gear all have to be right. The drive concept — gearbox, girth gear or gearless — should be settled before the mill is ordered, not after.
We help overseas buyers specify, evaluate and purchase ball mills from vetted Chinese manufacturers, and we supply the complete mill drive package separately.
What we do for you
Technical specification
We turn your process requirement into a written technical specification that manufacturers can be compared against — capacity, materials, duty, standards and inspection requirements.
Supplier shortlisting
We shortlist qualified manufacturers for each project and compare their proposals against your capacity, material and site conditions, so the recommendation follows your actual duty.
Factory audit
We assess production capacity, welding and machining capability, quality systems and export experience before a manufacturer is recommended.
Quality control and inspection
We review drawings and material certificates during manufacture, and carry out dimensional checks and pre-shipment inspection before anything leaves the factory.
Commercial and contract support
We support specification of payment terms, delivery milestones, inspection and acceptance conditions and documentation, so the contract reflects what was actually agreed.
Logistics coordination
We coordinate packing, marking, shipment and export documentation, including disassembly planning and packing lists for oversized assemblies.
How the process works
- 1
You send the process requirement, site conditions and the budget range.
- 2
We prepare a written technical specification and confirm it with you.
- 3
We shortlist qualified manufacturers and compare their proposals on the same basis.
- 4
We audit the shortlisted manufacturers, clarify technical and commercial points with them, and present the results for your decision.
- 5
We monitor manufacture, review drawings and certificates, and witness testing.
- 6
We carry out pre-shipment inspection and coordinate packing, shipment and documentation.
What to tell us when you enquire
This is the information we need to write a specification and compare manufacturers on the same basis. Partial data is fine — we will tell you what is missing.
Specification and site data
| Mill size | internal diameter and length in m, single or two-compartment |
|---|---|
| Capacity | throughput in tph, and the required product fineness |
| Material | Bond work index in kWh/t, feed size, moisture, temperature |
| Mill speed | operating speed in rpm, and as a percentage of critical speed |
| Drive concept | gearbox, girth gear, or gearless mill drive — we will advise |
| Liners and media | liner material and profile, ball charge in t, whether included |
| Circuit | open or closed circuit, and the classifier arrangement |
| Site conditions | ambient temperature, altitude, power supply and voltage |
Key components we also supply
The drive and control package can be supplied with the machine or separately. Supplying both keeps the mechanical and electrical interface consistent, and means the spares are available from the same place.

Looking for a machine that is not listed here?
These are the machines clients ask us for most, not the limit of what we handle. If you are procuring any other type of industrial equipment from China, send us the specification, the drawings, or a photo of the nameplate. We shortlist qualified manufacturers, review the technical proposals, audit the works, inspect before shipment and coordinate export delivery.

Frequently asked questions
Should the drive concept be decided before the mill is ordered?
Yes. Whether the mill uses a gearbox, an open girth gear set or a gearless drive affects the shell design, the foundation and the spares strategy, so it should be settled early.
Do you supply the mill drive separately from the mill?
Yes. We supply the medium-voltage motor, mill gearbox or girth gear, drive and inching drive as a package, whether or not the mill itself is bought through us.
Do you only supply the eight brands shown on your homepage?
No. We source and supply spare units and parts for most international and Chinese industrial brands, not only the eight brands shown on this site.
I do not know the exact model number. Can you still quote?
Yes. Send us a photo of the nameplate and we will identify the exact unit before preparing the quotation for the original part.
Do you supply genuine original manufacturer parts?
Yes. We supply genuine original manufacturer parts. Send us a photo of the nameplate and we can identify the exact unit before quoting, so you do not need to look up a model number.
Do you provide installation guidance, commissioning and after-sales support?
Yes. We provide installation guidance, commissioning support and after-sales support, remotely or on site depending on your project.
What is the delivery time?
Lead time depends on the product and configuration. We confirm the delivery schedule together with the quotation, so you have a firm date before you order.
Which export documents and certificates can you provide?
We can provide applicable CE and ISO documentation, certificates of origin, packing lists and test reports according to the requirements of your destination country.
What payment terms and incoterms do you work with?
We accept T/T and L/C payment, and quote FOB, CIF or EXW terms to suit your project.
Tell us the requirement and we will shortlist qualified manufacturers
We select manufacturers based on your requirements. We prepare the technical specification, compare qualified manufacturers on a consistent basis, and inspect before anything ships.
