Description

[0001]
[Industrial application fields]
The present invention is an invention relating to a cereal chamber of a horizontal grinding type pulverizer.
[0002]
[Prior art]
Conventionally, the grinding roll is surrounded by a descreening screen to form a cereal chamber, and one side of the cereal chamber is continuously connected to the cereal cerealing room, and the other side is provided with a crocodile outlet. In the horizontal grinding type rice milling machine, a grinding mill is formed by combining a plurality of grinding milling pieces, and an annular resistor perpendicular to the grinding roll is fixed to divide the milling room. No. 6-134325. In addition, axially mounted the angle adjustable resistance claw inwardly in a portion connecting the arcuate dividing sugar screen, although ventilation rice apparatus for controlling the wave resistance of the rice grains are described in JP-A-62-11555 In the former, only the wear of the grinding roll is taken into account, and if this wears, the removal screen replaces the flap of the wafer with a higher one to correct the gap between the grinding roll and the flap. Therefore, it takes a labor and time for replacement to correct the interval, and several types of replacement parts must be prepared. In the latter, a resistance claw that enables rotation adjustment is installed in a single-structured cereal chamber, and the rice grain density is made uniform while receiving the assistance of ventilation. It is the structure which produces the stagnation of a grain for every grain room.
