【発明の名称】旋動式破砕機の出口隙間検出方法
Document Type and Number:
Japanese Patent JP3061246
Kind Code:
B2
Abstract:
An angle theta formed between a horizontal line passing through the contact point P and a slant surface of a mantle based on an empirical rule corresponding to the vertical distance L ranging from the reference line S to the contact point P of the mantle continued to vary due to abrasion is inputted in advance into an angle inputting and outputting device, the angle theta corresponding to the vertical distance L detected by a distance sensing device in reference to an angle inputted value is selected and at the same time the selected angle is inputted into the distance calculating device, a product of a distance difference DELTA L between the contact point P of the concave and the contact point P of the mantle and a cosine value of the angle theta is calculated by the distance calculating device, resulting in that an inputting operation for the angle theta can be eliminated, so that a stop time of the cone crusher is reduced and an operating efficiency of the cone crusher is improved.
