AI Technical Summary
The drive mechanism of traditional asphalt raw material screening equipment is prone to rapid wear and high noise.
The oscillating mechanism and drive mechanism drive the screening seat to oscillate regularly. The screening seat and its screen plate oscillate continuously according to the set trajectory, reducing equipment wear and noise.
The design of the oscillating mechanism and drive mechanism reduces equipment wear and noise, and improves screening efficiency and equipment life.
