WPM ZD-18S

Equipment notes

The ZD-18S is an electric grinder from the Chinese coffee-equipment brand WPM (Welhome), a commercial-oriented model built around 64mm flat steel burrs. With a portafilter holder, an LCD touch panel and one- and two-cup dosing timers, it targets both cafe counters and home espresso setups. Coarseness is set through multiple steps. The 64mm flat burrs have a geometry that raises particle uniformity and helps with heat and throughput. Fines are comparatively controlled, reducing channeling and supporting stable extraction in espresso. Grinding straight into the portafilter and an anti-static chute add practical convenience, and its range is centered on espresso. It suits cafes and home baristas who pull espresso frequently and heavy users who value even grinding and dosing convenience.
