Abstract

This utility model relates to the field of crushing equipment technology and discloses an industrial solid waste crushing device, including a main body. Support legs are fixedly installed at the bottom of the main body, and a discharge port is fixedly sleeved at the center of the bottom of the main body. A secondary grinding roller is fixedly sleeved at the bottom of the inner cavity of the main body. This utility model improves the crushing effect by setting a secondary grinding roller at the bottom of the inner cavity of the main body, so that after the waste is first crushed by the primary crushing blade and auxiliary blades, it falls onto the secondary grinding roller for a second stage of crushing. This avoids the direct discharge of poorly crushed waste into the environment, which would cause subsequent processing difficulties, thus improving the practicality of the device. Simultaneously, a return pipe is set on one side of the main body, and an lifting paddle is installed inside the return pipe for lifting, thereby re-crushing the unqualified waste, improving the ease of use of the device.
