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).
1-11. (canceled)
A comminuting device for laboratory operation, comprising;
The comminution device according to claim 1, further comprising at least one integrated damper formed by the housing parts of the comminution device bordering the milling material channel, the housing parts adapted for passive reduction of sound emissions by at least partial reflection of sound from cross-sectional changes in the housing parts, directional changes in the housing parts, or a combination thereof.
The comminution device according to claim 1, further comprising at least one integrated damper formed by portions of the comminution device connected to the housing assembly and bordering the milling material channel, the portions adapted for passive reduction of sound emissions by at least partial reflection of sound from cross-sectional changes in the device parts, directional changes in the device parts, or a combination thereof.
