Abstract: The present invention relates to an impact crushing apparatus that mills grain between a milling cylinder and a screen. Each of a plurality of blades mounted along the circumference of the milling cylinder comprises a columnar body with a square cross section, cutting tools disposed on all ridges of the columnar body, and mounting parts formed at the top and bottom of the columnar body. Each blade is attached to the milling cylinder in such a way that any one of the four directions of the blade can be selected by rotating the blade around the central axis of the columnar body.

Abstract: A break roll machine wherein a timing belt of a differential transmission mechanism can be removed easily and wherein the removal of a roll pack module from a machine frame and the installation of the new pre-assembled roll pack module can be performed easily in a short time is disclosed. A cutout portion is provided to one of a paired tension arms so that the one tension arm is rotatable around a pivot point at an upper portion of the tension arm. As a rotary shaft of an idler pulley is released from the tension arm through the cutout portion, the timing belt can be removed easily. An air cylinder is rotated freely by a first and a second linkage member. An operator can easily access to a bolt located behind the air cylinder only by inclining the air cylinder at any desired direction.

Abstract: A cereal separation apparatus includes a frame and a size grading device mounted at an upper portion of the frame for grading particles according to a size of the particles. An oscillating specific gravity grading device is mounted at a lower portion of the frame. An air flow-producing device produces an air flow for effecting the specific gravity grading. A feed passage feeds the particles, selected by the size grading device, from the size grading device to the specific gravity grading device. The size grading device comprises a perforated, hollow cylinder for grading the particles according to particle size. The cylinder is supported on the frame for rotation about an axis of the cylinder. The specific gravity grading device is supported on the frame through oscillation support portions. The apparatus further comprises a rotation drive device for rotating the hollow cylinder and an oscillation drive device for oscillating the specific gravity grading device.
