Description
Single dosing on the Gemilai CRM9012
The CRM9012 is the larger machine in Gemilai’s grinder line: 64 mm flat burrs, a 350 W motor, and a body standing about 678 mm tall. The bean hopper holds 1.2 kg.
That is a genuine commercial hopper, and it changes the calculation compared with Gemilai’s smaller grinders. Where the CRM9009 carries around 120 g, the 9012 is designed to be filled and worked through across a shift.
The mismatch with weighed dosing
1.2 kg of beans committed above the burrs means one coffee at a time, staling as it waits, and a full emptying every time you want to change. If your CRM9012 is at home, in a roastery, or being used to dial in rather than to serve, none of that is what you need.
This hopper replaces it so each dose goes in weighed and alone. After grinding, pressing the silicone bellows pushes grounds out of the 64 mm chamber and chute instead of leaving them to blend into the next dose.

Fitting
This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
