The YEH-80L is developed to meet the demands of specialty coffee grinding, built around a large-burr platform, stable spindle, efficient maintenance, and low-retention workflow. The combines an 80mm burr system, a 1500W brushless FOC motor and 300–2000 RPM control for espresso and filter workflows that demand repeatability.
Key Features:
80mm flat burrs without locking you into one profile
The YEH-80L is designed as a flexible 80mm platform. Its supplied LeBrew 80 Core magnetic blind burr supports a clarity-led starting profile, while compatibility with selected SSP and LeBrew burrs lets experienced users tune the grinder around espresso, filter or roast style. Confirm fit before installing any third-party burr.
Variable speed with stable torque
The 1500W brushless FOC motor provides a 300–2000 RPM range. Lower and higher speeds can change workflow and cup presentation, giving you another controlled variable after burr choice, dose and grind setting.
Low-retention single-dose workflow
A compact path and magnetic blind-burr configuration are designed to reduce places where grounds can collect. With specified retention of 0.1g or less, the grinder suits users who change coffees often or want dose-to-dose consistency.

FAQ
What grind settings should I start with?
For espresso with the stock burr, start at dial position 3 and a motor speed of 1000–1500 RPM. For pour over, try 10–11.5 at 200–700 RPM. Light roasts need finer settings; dark roasts need coarser. On first power-on, set the dial to position 30 (not 0) to avoid burr contact.
Can the YEH-80L grind for espresso and pour-over?
Yes. Its stepless adjustment and variable-speed motor support espresso and filter grinding. Your burr choice will strongly influence the final cup profile.
How often should I clean the grinder?
A full deep clean is recommended every 15 days. Unplug first, detach the powder spout and hopper, unscrew the 4 top bolts with the included hex key, and lift the upper section to expose the burrs. Clean with the included brush or a small vacuum. Wipe mating surfaces before reassembling.
Will my grind setting change after cleaning or a burr swap?
No. The patented internal leveling mechanism and independent spindle are designed so that disassembly for cleaning or burr replacement does not affect grind calibration. Your dial position stays accurate after reassembly.
Is the YEH-80L compatible with 110V / 120V power?
The YEH-80L is rated for 220V / 50–60Hz. North American customers will need a step-up voltage transformer. Please verify your local power requirements before ordering.
Precautions for Scale Adjustment
This machine is manufactured with the 0 mark set as the tool setting position. Do not tighten the scale beyond 0 before turning on the machine, as this may cause wear on the tool disc and affect accuracy.
When adjusting the scale, it is recommended to first set the speed to the lowest setting while the machine is powered on, and then make fine adjustments to the scale. Scale adjustments should follow the principle of "from large to small". For example, if the target scale is 3, you can first back down to 4, and then slowly back down to 3 to obtain a more stable and accurate positioning.
Who should choose the YEH-80L instead of the YEH-83C?
Choose the YEH-80L for flat-burr separation and burr-platform flexibility. Choose the 83C if you prioritize conical-burr body, sweetness and a more integrated espresso profile.
Safety Warning
The equipment has undergone precision testing and blade leveling before leaving the factory. Do not loosen the leveling screws yourself. If disassembly or adjustment is required, please contact after-sales personnel first.
Before disassembling any equipment part, the power must be turned off. It is strictly forbidden to disassemble any equipment part while the machine is powered on, especially critical components such as the bean inlet and powder outlet.
Do not grind anything other than coffee beans. Do not insert fingers or foreign objects into the grinding or powder outlet areas while the equipment is running.
If abnormal noise, odor, or overheating occurs, immediately stop the machine, disconnect the power, and contact after-sales service.
