摘要： PROBLEM TO BE SOLVED: To provide a soil classifier with a simple structure and an enhanced classification efficiency. SOLUTION: Soil is subjected to vibration screening with a vibrating grid 3 and then transported by a conveyor 4. While being conveyed by the conveyor 4, the soil is agitated with an agitation device 5. The agitated soil is transferred to a classification conveyor 7 and transported at a high speed. At a gate 8 installed at the transportation end, the soil is subjected to soil selection of specified particle sizes to be classified. The soil is classified into soil with a specified particle size or larger and soil with a specified particle size or smaller. Thus, the soil classifier can be given a simple structure, is easily installable on the site, can classify charged soil through a plurality of steps, has a construction capable of performing aeration, and is excellent in efficiency.

摘要： PROBLEM TO BE SOLVED: To provide an impact type crusher which can control adhesion of particulates, etc. to any part of the outer peripheral surface and clearances of the rotor shaft because of its construction allowing an air flow to reach the outer peripheral surface of the rotor shaft, i.e. the deepest part of clearance between the end surface of the rotor and side wall of the casing.
SOLUTION: A through hole 40 for the shaft is formed in the side wall 12 of the casing opposing the end surface 20 of the rotor, and the rotor shaft 21 is inserted through the through hole and held. A void S1 is formed between the inner periphery of the through hole and the outer periphery of the rotor shaft by making the inside diameter of the through hole larger than the outside diameter of the rotor shaft. Air is sucked externally into the clearance through the void as the inside of the casing becomes negative-pressure owing to high-speed rotation of the rotor, and the sucked air is made to flow toward the outer periphery of the rotor.
