シングル・トッグル・ジョウ・クラッシャの破砕荷重に関する2, 3の考察

抄録

In this paper, we, the present authors, will describe the experimental and theoritical studies of the crushing mechanism of a single toggle jaw crusher.
In this research, the following results were obtained;
(1) In crushing with the crusher, the crushing load is influenced by the component of velocity of the movable jaw face that gives the compressive load.
(2) If the diameter of each spherical test piece is constant, the component of velocity is decided by the angle of a nip and the number of revolutions per unit time made by the crusher.On the other hand, about the theoritical studies, we will describe the internal stress of the lump of rock loaded by jaw crusher.
And this research were made as to the following problems;
(1) The stress from the elastic learning point of view on the supposition that the sphere is a disk of two dimensions.
(2) The direction and the position of the breaking line.
(3) The stress on the center of the breaking line.
In order to confirm these analyses, the method of photoelasticity was adopted in the experiment
