Stone mill for fine powdered tea



The utility model relates to a stone mill for fine powdered tea, which comprises an upper mill and a lower mill. The upper mill and the lower mill can relatively rotate and are respectively provided with mutually opposite abrasive surfaces, and a concave cavity is at least formed on the abrasive surface of the lower mill. The speed of grinding tea leaves from the center of the stone mill towards the outer periphery of the stone mill can be decelerated by the aid of the concave cavity formed between the upper mill and the lower mill, in other words, the concave cavity arranged on the lower mill has a certain buffering function for the tea leaves being grinded from the center of the stone mill towards the outer periphery of the stone mill, so that the tea leaves are grinded more finely so as to meet the requirement of manufacturing the fine powdered tea.
