Small mill having a rotor inclined relative to the axis of the feed chute

摘要

A small mill is essentially composed of a feed chute (1) discharging onto a rotor (2) equipped with milling and/or cutting hammers (3) interworking with a milling housing (4) that is equipped with screening walls (5), a crusher element (6) that can be provided upstream from the rotor (2), above the feed chute (1) and at a distance from the latter. The mill is characterized in that the axis of the rotor (2) is inclined relative to the axis of the feed chute (1) by forming an acute angle with the latter. This mill can be applied more particularly in the field of processing materials of any origin, especially by shredding with crushers, hammer mills, or the like.

主权项

1. A small mill, comprising:
a milling housing (4) with screening walls (5); a rotor (2) equipped with at least one of the group consisting of milling hammers and cutting hammers (3) interworking with said milling housing (4), the rotor having an axis; a feed chute (1) comprised of a bottom part with an upper portion and a lower portion, the bottom part defining a longitudinal median axis (L) of the feed chute, the feed chute (1) configured for receiving material at the upper portion, the material moving in a discharging direction down the bottom part towards the lower portion and discharging onto said rotor (2), wherein the axis of the rotor (2) is inclined, at an acute angle (α), relative to the longitudinal median axis of bottom part of the feed chute (1); and a milling and shredding chamber defined by a beveled space (BS) located vertically between the rotor (2) and an upper surface of the lower portion of the bottom part of the feed chute (1), wherein the rotor (2) extends, in vertical registration, at least partly over the lower portion of the bottom part of the feed chute (1), and the milling and shredding chamber is of progressively decreasing dimension in the discharging direction in correspondence with a cross-section of said beveled space decreasing in the discharging direction.
