Definitions

  • a stopper portion 102 is formed on the outer periphery of one end side of the support portion 101 of the housing 100, and an annular groove portion fitted to the stopper portion 102 is formed on the inner periphery of the one end side of the roller 110. 113 is formed. Further, an annular groove portion 103 to which the holding plate 120 is attached is formed on the outer periphery of the other end side of the support portion 101 of the housing 100, and an annular groove portion to which the holding plate 120 is attached to the inner periphery of the other end side of the roller 110. 114 is formed.
  • the solid material pulverized by the pulverizing roller 10 becomes a pulverized material, and is lifted while being dried by the primary air sent into the housing 11 from the inlet port 24 by driving the primary blower.
  • the raised pulverized material is classified by the rotary separator 26, the coarse powder falls and is returned to the pulverization table 13 again to be pulverized again.
  • the fine-grained powder passes through the rotary separator 26 and rides on the airflow. And discharged from the outlet port 27. Further, spillage such as gravel and metal pieces mixed in the solid matter is dropped outward from the outer peripheral portion by the centrifugal force of the crushing table 13, and is discharged by the foreign matter discharge pipe 28.
  • a stopper portion 102 is formed on the outer periphery of one end side of the support portion 101 of the housing 100, and an annular groove portion fitted to the stopper portion 102 is formed on the inner periphery of the one end side of the roller 110. 113 is formed.
  • An annular groove 103 to which the holding plate 120 is attached is formed on the outer periphery of the support portion 101 of the housing 100, and an annular groove that fits with the stopper portion 102 is formed on the inner periphery of the other end of the roller 110. 114 is formed.
  • the holding plate 120 is a plate formed in an annular shape, and the annular groove 103 on the other end side of the housing 100 and the annular portion on the other end side of the roller 110 in a state where the roller 110 is fitted on the outer periphery of the support portion 101 of the housing 100. It is attached to the groove 114 and fastened to the housing 100 by a large number of bolts 121.
  • the crushing roller 10 of this embodiment is characterized by the shape and size of the tab hole 204A of the housing 100 and the shape of the tab 230A, as shown in FIGS. 1A and 1B.
  • 1A and 1B are cross-sectional views of the housing 100 and the tab holes 204A and 115 of the roller 110 that are broken at the center in the circumferential direction (center in the rotation direction) and showing half of the tab holes 204A and 115. The half is formed in a symmetrical shape.
  • 1A shows a state in which the tab 230A and the shim 132 are mounted
  • FIG. 1B shows a state in which the tab 230A and the shim 132 are removed.
  • the tab 230A is also formed to be large in the radial direction in accordance with the shape of the tab hole 204A, and faces the rotation direction surface 230a of the tab 230A that faces the rotation direction surface 204a of the tab hole 204A and the bottom surface 204c of the tab hole 204A.
  • the bottom surface 230c of the tab 230A is also formed in accordance with the shape of the tab hole 204A.
  • the tab hole 115 of the roller 110 is not particularly changed.
  • rotation direction surface 204a of the tab hole 204A and the rotation direction surface 230a of the tab 230A are expanded as compared with the case where the base portion of the rotation direction surface 204a of the tab hole 204A is aligned with the base portion of the stopper portion 102 in the radial direction.
  • the rotational force transmitted to the rotational direction surfaces 204a and 230a is dispersed by the expansion of the contact area, and from this point, stress concentration is alleviated.
  • the line L2 where the fastening stress due to the presser plate 120 at the base of the stopper 102 is concentrated and the line L1 where the stress due to the grinding load received by the roller body 110 at the base of the tab hole 204A of the roller housing 100 is concentrated are shifted. Therefore, stress concentration is reduced.
  • the rotational direction surface 204a of the tab hole 204A is expanded, the rotational direction force transmitted by the rotational direction surfaces 204a and 230a is dispersed, and the stress concentration is alleviated. Furthermore, since the boundary portion between the rotation direction surface 204a of the tab hole 204A and the bottom surface 204c of the tab hole 204A is connected to the smooth curved surface 205, stress concentration is reduced.
