Description

Technical Field

[0001] The utility model belongs to the technical field of bouncing screens, and in particular relates to a bouncing screen lifting device. Background Art

[0002] The bouncing screen is an advanced garbage sorting equipment. It drives the screen box to produce bouncing motion through a vibration motor, achieving efficient and accurate grading and screening of materials. Compared with traditional screening equipment, the bouncing screen has the advantages of high efficiency, low noise, low energy consumption, and easy maintenance. It is widely used in the screening of various solid wastes and contributes to garbage classification and recycling.
