Welhome ZD15 12 Electric Grinder: Cone Burr Specs & Color Guide

If you've just unboxed a Welhome ZD15 12 electric grinder—or are eyeing one—you might be staring at a mix of white, red, and wine-red parts with no clear idea which is which. New users often wonder which colored components match which internal part: is the white piece the top burr? What does the wine-red bit do? Understanding these distinctions helps with assembly, troubleshooting, and replacement.

The Welhome ZD15 12 electric grinder uses three colored parts: white for the upper burr, red for the lower burr, and wine-red for the upper and lower burr blades (also called the cutting edges or knife plates). These color codes make it easier to identify each component during assembly or replacement.

What Is the Welhome ZD15 12 Electric Grinder?

The Welhome ZD15 12 is a small-footprint, electric cone burr grinder commonly used in home and light commercial settings. Though details on its motor power, RPM, or grind range are not specified in the source, its defining visual feature for identification and part-matching purposes is the use of three colored components: white, red, and wine-red.

Color Coding of Grinder Parts

The grinder’s parts follow a simple and practical color-coding system:

• White: Represents the upper burr (the static or fixed burr cone).
• Red: Represents the lower burr (the rotating or driven burr cone).
• Wine-red: Represents the upper and lower burr blades, also known as the knife plates or cutting discs.

These colors help users correctly identify and orient each part during assembly, maintenance, or when ordering replacements.

Why Color Coding Matters for Users

For home baristas or small shop owners, misidentifying grinder parts can lead to incorrect assembly, uneven grinding, or premature wear. The distinct color coding on the Welhome ZD15 12—white, red, and wine-red—ensures that each component can be quickly matched to its role: the white upper burr, the red lower burr, and the wine-red burr blades. This visual guide simplifies setup, reduces errors, and aids in troubleshooting or ordering the correct spare parts.

Which part is the upper burr on the Welhome ZD15 12?

The upper burr is the white-colored part. It remains fixed in place during grinding and works in tandem with the rotating lower burr to crush coffee beans.
