Abstract: A comminution device for laboratory operation is described. More specifically, a laboratory mill, particularly a centrifugal mill, is provided that includes a milling tool arranged in a milling chamber, a housing assembly, and a milling material channel running through the housing assembly. The milling material channel opens into the milling chamber and is configured to supply, for supplying milling material to the milling chamber or to discharge milled material from the milling chamber. The milling material channel may be open to the environment and/or can be opened for successively supplying milling material to the milling chamber during the milling operation. At least one system for passively reducing noise emissions is provided and situated in the region of the milling material channel.

Abstract: A comminution device (2) for laboratory operation is presented and described, particularly a laboratory mill, especially particularly a centrifugal mill, comprising a milling tool arranged in a milling chamber (3), a housing assembly and a milling material channel (12) running through the housing assembly and opening into the milling chamber (3), for supplying milling material to the milling chamber (3) and/or for discharging milled material from the milling chamber (3), particularly wherein the milling material channel (12) is open to the environment and/or can be opened, especially particularly for successively supplying a milling material to the milling chamber (3) during the milling operation. According to the invention, at least one system for passively reducing noise emissions is situated in the region of the milling material channel (12).
