摘要： PROBLEM TO BE SOLVED: To provide a water jet type reaction apparatus having high reaction efficiency, improved maintenance and excellent performance. SOLUTION: A reaction vessel 18 of this apparatus ejects a specimen water as underwater jets 8 accompanied by cavitation from an upper nozzle 1 of a V-shaped downward reaction tube 20. The jets 8 collide against a bottom 21 and the collided jets 22 ascend in a riser 19 from which the jets are discharged. When the high-velocity jets 8 collide against each other in the bottom, the air bubbles in the water are excited like chains by the impact and the cavitation is promoted. When a collision plate is disposed at the bottom, the collision impact is more improved. A large amount of the air bubbles join therewith as well and are released from a relief valve. The jets are separated after the reaction and during the progression of the reaction and the disturbance of the cavitation reaction is prevented by the cushion effect of the generated air bubbles. The maintenance of the V-shaped reactor may be easily carried out simply by withdrawing the nozzle section.

SOLUTION: In the pulverizing device which is provided with a pulverizing ring 1 freely rotatably supported and pulverizing rollers 2 for pulverizing a matter to be pulverized 18 between the pulverizing ring 1 and the rollers, layer thickness of the matter to be pulverized 18 present between the pulverizing roller 2 and the pulverizing ring 1 is measured by a displacement gauge 20 provided at the pulverizing roller 2. Generation of abnormal vibration is foreseen by layer thickness or layer thickness change of the matter to be pulverized by output signals of the displacement gauge 20 and the abnormal vibration is avoided by changing at least one among roller pressurizing force added between the pulverizing roller and the pulverizing ring and rotation number of the pulverizing ring. In the pulverizing device in which the pulverizing rollers 2 are supported so as to perform pendulum motion in a radical direction of the pulverizing ring 1, pendulum displacement of the pulverizing roller is measured by the displacement gauge 20 and the generation of abnormal vibration can be foreseen by the pendulum displacement measured by the displacement gauge 20.
