Description

Technical Field

[0001] The utility model relates to the technical field of crushing and grinding devices, in particular to a forsterite impact crushing and grinding device. Background Art

[0002] Forsterite is a refractory raw material with magnesium oxide and silicon dioxide as its main components. It belongs to ultramafic plutonic rock. Forsterite is not only an important refractory material, but also has a wide range of applications in ceramics and other engineering fields. Before forsterite is used, it needs to be crushed and ground to facilitate subsequent processing and use.

[0003] When the existing forsterite is crushed, it is usually combined with a crushing mechanism to crush the forsterite, and then the crushed forsterite is transported to a grinding device for grinding. The process is relatively cumbersome and requires secondary transportation of the forsterite, which wastes time and affects work efficiency. It is impossible to crush and grind at the same time. Therefore, a forsterite impact crushing and grinding device is proposed to solve the above problems. Utility Model Content

[0010] In order to achieve flexible control of the movement of the shielding plate;

[0011] As a further improvement of the above technical solution: a protective cover is fixedly connected to the upper end surface of the guide block, and the protective cover is slidably connected to the hydraulic telescopic column.

[0017] As a further improvement of the above technical solution: two symmetrical material guide plates are fixedly connected to the grinding box, and the material guide plates are located above the grinding roller.

[0018] The beneficial effects of this improvement are: by using the guide plate, the falling forsterite can be guided to the center of the two grinding rollers, which facilitates comprehensive grinding of the forsterite and prevents the forsterite from falling from both sides of the grinding box and affecting the grinding effect;
