Bead-mill internal architecture / RFQ evidence
Disc and peg describe internal grinding-system concepts, not a universal performance ranking. “Pin” may also appear in supplier vocabulary, but the proposal must define the term and identify the exact named system, chamber context and trial configuration before two quotations are compared.
Keep the comparison specific
The grinding system is one part of a complete bead-mill proposal. Compare it without allowing the name to absorb the separate media, separator, pass-mode or flow decisions.
Disc, peg and pin vocabulary may not identify identical geometry across suppliers. Request the supplier's own description, named configuration and controlled drawing or data reference instead of assuming equivalence from the label.
Keep grinding media, media retention, single-pass or recirculation, product hold-up, temperature control, cleaning and wear as separate review rows connected to the exact candidate machine.
Preserve the formulation, pre-dispersion, rheology, endpoint method, process route and recorded machine state. A result from another system, chamber or supplier is not automatically transferable.
Grinding-system review route
Use the same buyer-controlled product and acceptance basis, while requiring each supplier to keep its configuration and exclusions visible through the trial and release record.
Identify the controlled formulation, feed preparation, rheology state, process route, target and measurement method that every candidate must address.
Ask for the supplier's exact architecture description, configuration reference, connected chamber context, product path and stated scope boundaries.
Use an approved plan to record samples, endpoint progression, product condition, temperature behavior, contamination or wear observations, cleaning and deviations.
Have the responsible suppliers confirm the selected system together with its separate media, separator, operating route and production-transfer evidence, then control later changes.
Disc-versus-peg RFQ checklist
These fields organize evidence for a supplier comparison. They do not prescribe a disc, peg or pin design, an operating value or a JINPIONEER configuration.
Open the process briefFormulation reference, solids, carrier, pre-dispersion method, incoming particle or agglomerate state, rheology, temperature sensitivity and restricted contamination.
Required product change, endpoint value or observation, sampling basis, preparation, measurement method, repeats and disposition rule.
Supplier's exact disc, peg, pin or other terminology; named configuration; controlled drawing or data reference; revision; internal working description; and explicit exclusions.
Candidate mill and chamber context, product path, cooling and sealing interfaces, available instrumentation, guarding and supplier-approved operating boundary.
Grinding-media proposal, separator proposal, pass or recirculation route, effective hold-up or flow basis, cleaning route and the responsible approver for each row.
Approved machine state, material and media identities, samples, endpoint progression, product-temperature record, observed flow condition, deviations and stop criteria.
Contamination observations, wear inspection, product recovery, residue locations, dismantling boundary, cleaning verification, service access and changeover release.
Supplier confirmations, open items, accepted configuration and trial revision, production-transfer owner, replacement identity and triggers for renewed review.
Draft source record / Pending technical review
The Wet Grinding overview ties system selection to product properties; Alpha maps disk and peg systems to a named modular platform; LabStar maps Zeta, Discus and Neos to specific chamber designs; the DeltaVita 1 white paper uses pin-system terminology for named Zeta and Neos comparisons. Use that vocabulary to request exact drawings and trial identity.
Buyer decision FAQ
No. The cited OEM pages show that different named grinding systems exist and are selected in product and machine context. They do not establish a universal performance ranking. Compare the exact proposed configurations with the same representative material and acceptance basis.
Do not assume that they are interchangeable across suppliers. Ask each supplier to define its terminology and attach the name to a controlled architecture description, drawing or data reference for the exact candidate machine.
No. Media material and size, media-retention mechanism, operating route, hold-up or flow basis, temperature control, cleaning and wear need separate review and supplier confirmation, even though they interact with the complete mill configuration.
Not automatically. Keep the formulation, feed state, rheology, grinding system, chamber, media, separator, operating route, temperature history, sampling and measurement method attached to the result. Review differences and run a representative trial before production release.
Include the controlled feed, endpoint and method; each supplier's exact grinding-system identity and revision; complete mill context; separate media, separator and operating-route proposals; representative trial record; wear, recovery and cleaning observations; supplier confirmations; open items; and change-control triggers.
