Overview
The CGOLDENWALL DF-20 is a 1500W electric hammer mill built for pulverizing dry, oil-free herbs, spices, grains and other crude-fiber material at up to 44 pounds per hour. Interchangeable mesh screens set the grind from coarse meal to fine flour, and a 2840 rpm copper motor with a hard alloy steel hammer handles continuous batch feeding.
This is a commercial-grade mill, not a countertop spice grinder: it is sized for herbal shops, small mills and bulk kitchens grinding pounds of material at a time, not teaspoons. Material must be added slowly and in small batches to avoid jamming the crushing chamber, and it is built for dry, oil-free ingredients, so oily seeds or nuts are not a good match.
- 44 lb/hr rated capacity
- 2840 rpm copper motor, 1500W
- Coarse and fine mesh screens included
- 1-year warranty
Who it's for
Buyers running a small herbal, spice or grain milling operation who need to process pounds of dry material per hour rather than home cooks looking for a spice grinder. Not suited to anyone wanting to mill oily or sticky ingredients, since the machine is built for dry, crude-fiber material.

Strengths and trade-offs
Drawn from this product's published specifications.
- Interchangeable mesh screens for coarse meal or fine flour
- Continuous feeding lets you keep grinding without stopping
- Hard alloy steel hammer and copper motor built for repeat use
- 1-year warranty with lifetime technical support
- Only rated for dry, oil-free, non-sticky material
- Feeding too fast or in large amounts can jam or overload the motor
- Only 3 reviews on record, too few to judge long-term reliability
Performance notes
Output depends on which mesh screen is fitted: a fine mesh produces flour-grade powder from dry herbs, while a coarser mesh handles both dry and slightly oily material and yields a meal instead of a powder. The continuous-feed design lets material be poured in while the mill runs, but the manufacturer cautions that feeding must be slow and in small amounts, since dumping material in quickly can jam the crushing chamber and overload the motor.
