Prima 83 Flat — Grind by Weight
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Grinders — where the cup is decided
Shops upgrade machines and discover the grinder was the ceiling. The Prima raises it — shop-speed throughput, tight particle spreads, and burr life measured in tonnes, tracked by the counter.
Burrs are the whole argument. Ours are cut from hardened tool steel or coated in titanium nitride, measured on an optical comparator, and matched in pairs; carriers are machined, not cast, so alignment survives shipping, seasons and years of shots. Chirp-free at zero, even after the ten-thousandth kilogram.
Design & Craft
- Machined burr carriers hold alignment through shipping and seasons
- Grind-by-weight dosing lands within a tenth of a gram
- Commissioned and re-checked for alignment after transport
- Quiet under load — low 70s dB(A) at full song
- Motor wound for torque without heat; sealed oversized bearings
- 83–98 mm flat tool-steel burrs for shop-speed espresso with tight spreads

Questions, Answered
Will it work for both espresso and filter?
Single-dose models with stepless adjustment travel the whole range comfortably. Dedicated shop grinders are happiest owning one brew method — we will advise honestly if a listing is being asked to do too much.
Does it come aligned?
Every unit is shimmed and chirp-checked before dispatch, then re-checked after transport at commissioning. Alignment is a deliverable, not a lottery.
