Description

Technical Field

[0001] The utility model relates to the technical field of forsterite preparation, in particular to a classification and purification device for preparing silica gel from forsterite. Background Art

[0002] Forsterite refers to a refractory raw material with magnesium oxide and silicon dioxide as the main components. It is a mineral that is more resistant to high temperatures among magnesia refractory materials. Forsterite belongs to the orthorhombic crystal system and is mostly in the form of short columnar particles. It is composed of three cylindrical shapes, three axial shapes and one biconical shape, or in the form of thick plates or round particles.

[0003] At present, when chemical plants use forsterite as a raw material to produce silica gel, they first need to classify and purify the forsterite. The existing forsterite is screened using a purification screening machine. During the screening process, the purification screening machine will screen the forsterite in order from large to small according to its volume. In this way, in the process of screening the forsterite with a larger volume, the forsterite with a smaller volume will also be screened out. This makes the screened forsterite not fine enough, and it needs to be screened and classified multiple times, and the process is complicated. Therefore, we propose a classification and purification device for preparing silica gel from forsterite to solve the above problems. Utility Model Content
