The YEH-80L is an 80mm flat burr single-dose coffee grinder designed for specialty coffee enthusiasts who want greater control over burr selection, grind consistency, and brewing style. It combines an 80mm burr platform, a 1500W brushless FOC motor, and 300–2000 RPM control for espresso and filter workflows that demand repeatability.
Key Features:
80mm Flat Burr Platform
Compatible with a range of 80mm flat burrs, including blind and through-hole designs. Users can select different burr geometries based on espresso, filter, roast level, and preferred flavor profile.
Low-Retention Single-Dose Workflow
The YEH-80L is designed around individual weighed doses with ≤0.1g retention, helping reduce carryover when changing coffees or recipes.
1500W Brushless FOC Motor
A 1500W brushless motor with FOC provides stable torque and speed control for the demands of a large 80mm burr platform.
Precision Independent Spindle
The independent spindle and angular-contact bearing structure are designed for micron-level alignment and stable burr positioning.
Quick-Access Maintenance
The upper assembly can be removed for routine burr cleaning and maintenance while the internal alignment structure helps preserve calibration after reassembly.
Espresso & Filter Flexibility
Use the YEH-80L for espresso, pour-over, and filter grinding by pairing the grinder with the appropriate burr profile and grind setting.

Why Choose an 80mm Flat Burr Grinder?
An 80mm flat burr grinder offers a large-burr platform for users who want more flexibility in burr geometry without immediately moving to a 98mm or 120mm grinder. The YEH-80L supports compatible 80mm blind and through-hole burr designs for espresso, filter, and pour-over grinding.
Combined with a low-retention single-dose workflow, precision adjustment, and a rigid spindle system, the YEH-80L is designed for coffee enthusiasts who want greater control over grind settings, burr selection, and brewing style.

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.
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 suitable 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.
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.
