Irony sundries in broken material.In the present invention, first help roll 35, the second help roll 36 and third help roll 37 are in isosceles
Triangle-Profile is mounted on first help roll 35, second help roll 36 and the third help roll 37 broken
Hammer, the roller diameter of first help roll 35 are greater than the roller diameter of second help roll 36 and the third help roll 37, and described the
Two help rolls 36 are identical with the roller diameter of the third help roll 37.First help roll 35, second help roll 36 and institute
Can first bulk particle harder in material be smashed by stating third help roll 37, on the one hand be can be avoided bulk particle and be directly entered
The broken roller unit 20；On the other hand it is able to carry out and is tentatively crushed, can effectively refine crushed particles, improve material
Crushing effect.In the present invention, it is made of first help roll 35, second help roll 36 and the third help roll 37
The isosceles triangle is positive isosceles triangle, and the roller diameter of first help roll 35 is set greater than second help roll
36 and the third help roll 37 roller diameter, can enable the maximum of first help roll 35 being located at the top of isosceles triangle
The broken material of limit will be located at the roller diameter of second help roll 36 and the third help roll 37 of isosceles triangle bottom
The roller diameter for being set smaller than first help roll 35 is in order to ensure there is enough spaces to accommodate above first housing 21
Material avoids material from blocking.
The embodiment is to be illustrated the present invention, and is not intended to limit the present invention.Anyone skilled in the art
Without departing from the spirit and scope of the present invention, it modifies to the embodiment, therefore rights protection model of the invention
It encloses, should be as listed in the claims of the present invention.
