Description

Technical Field

[0002] Organic solid waste refers to solid organic items and materials that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned in production, life and other activities, such as crop straw. When crop straw is regularly processed, it is usually collected and fermented to process products such as organic fertilizer. However, before fermenting the straw waste, it is often necessary to crush it for better fermentation and processing. Crushing is one of the solid waste pretreatment technologies. Controlling the size and shape of the solid through crushing is conducive to the resource utilization and reduction of solid waste.

[0003] The Chinese patent (authorization announcement number: CN 215965457 U, authorization announcement date: 2022.03.08) proposes an efficient solid waste crushing device. The patent sets a compression chamber and a crushing chamber to efficiently compress and crush solid waste, operate continuously, and save time.
