A comminuting device of biological material includes a casing that contains fixed cutting elements and movable cutting elements cooperating with each other to grind biological material, a collecting chamber for ground biological material, and a partition wall adjacent to the collecting chamber. The fixed and movable cutting elements are above the partition wall together with the biological material to be ground. The collecting chamber is below the partition wall. The fixed cutting elements are in the form of elongated corners that extend radially. The movable cutting elements are in the form of elongated corners that extend radially. The partition wall is provided with wall portions. Calibrated holes are provided for the passage of biological material ground by the fixed cutting elements and the movable cutting elements. The collecting chamber is in connection with the outside of the casing through at least a channel.

A mill including a mill body including a feeding pipe and a discharging pipe; a motor; and a vessel including a feeding port, a discharging port, and a supporting base. The vessel is disposed outside the mill body, and a sealing space is formed between the vessel and the mill body. The feeding port is disposed on the outer wall of the upper part of the vessel and is in a seal-tight connection with the feeding pipe of the mill body through a soft feeding joint, and the discharging port is disposed on the outer wall of the lower part of the vessel and is in seal-tight connection with the discharging pipe of the mill body through a soft discharging joint. The supporting base is disposed at the bottom of the vessel, and the mill body is installed on the supporting base via a cushion pad.

A vertical and horizontal mills and discs therefor for grinding particles to submicron size. The mills include two overlapping vertical barrels. Each barrel has a shaft and a plurality of circular discs attached to the shaft disposed in each barrel for grinding materials to submicron size. The discs have an open mesh design provided by overlapping rectangular blades. Each blade has at least two opposing walls orthogonal to a plane defined by the disc. Each disc on one shaft overlaps a disc on the other shaft by from 30 to 45% of the diameter of the discs. An inlet is provided for feeding material to be ground by the mill to the overlapped portion of the discs. An outlet is disposed at an end of the mill opposite the inlet for removing ground material from the mill.
