The manual coffee grinder made of heavy block metal material has a gray three-compartment wheel, a solid and light bolt when grinding, a strong four-tooth screw to make the grinder’s rotating shaft more sturdy, and a funnel with three sharp grinding blades. The funnel holds 500 grams of roasted green coffee beans to finely grind the coffee, suitable for brewing by the Moka pots and paper filters. The drawer below is easy to pull out of the grinder when finishing the first batch of 500 grams of coffee powder. If people want to be surer when grinding coffee, they often use screws to fasten to the wooden pedestal so that grinding coffee fine becomes easier than ever.
