CRUSHING METHOD, CRUSHING APPARATUS, AND CRUSHING SYSTEM

摘要

PROBLEM TO BE SOLVED: To enhance the efficiency of refuse treatment and reutilization by finely crushing a bulky material such as polyvinyl chloride or the like. SOLUTION: The crushing method consists of a first process wherein a material to be crushed comprising a synthetic resin is charged in a container main body 6 to be cut between fixed blades 7 and rotary blades and the finely torn material to be crushed is smashed and rubbed in the gaps between the rotary blades 8 to be softened and melted by generated heat and a second process sprinkling water over the molten material to be crushed to solidify the same and finely crushing the solidified material in the gaps between the rotary blades. A crushing apparatus is equipped with the fixed blades 7, the rotary blades 8 rotated while keeping slight gaps between the fixed and rotary blades not only to cut the material to be crushed in the gaps between the fixed and rotary blades 7, 8 but also to crush and rub the same to generate heat, a cooling water supply means sprinkling water over the material to be crushed which is smashed and rubbed to be melted by generated heat and an ammeter detecting a change in the viscosity of the material to be crushed as the change of the current of a drive motor. A dust collector and a deodorizing apparatus may be provided.
