Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a granulation equipment for saline-alkali land improvement materials based on oil shale. Background Technology

[0002] Oil shale is rich in organic matter and minerals. After processing, it can be used as a soil conditioner or fertilizer, which can significantly improve the physical and chemical properties of soil, enhance its fertilizer retention capacity, and promote the accumulation of root and leaf biomass. Oil shale is suitable for the improvement of saline-alkali land, especially for mild to moderate saline-alkali land. In order to facilitate uniform spreading in practical applications, oil shale needs to be processed into granules using granulation equipment.

[0003] Currently, in the use of existing oil shale modified material granulation equipment, most of the components are fixed and connected by bolts. When it is necessary to replace the granulation orifice plate according to different granulation size requirements, tools must be used to disassemble each bolt one by one in order to remove and replace the granulation orifice plate located inside, which is cumbersome and time-consuming.
