1. The trough plates utilize double-arc plates to effectively prevent material leakage.
2. The traction chain utilizes a separate load-bearing and traction structure, improving the apron feeder's ability to withstand impact loads.
3. The tail pulley is equipped with a disc spring to mitigate chain impact loads, extending the chain's service life.
4. The chain apron feeder consists of five parts: the head drive unit, tail pulley assembly, tensioning unit, chain plates, and frame.
5. The tail has shock-absorbing sleepers and a special shock-absorbing roller in the middle, improving the load-bearing conditions when large materials impact the rollers and trough plates on both sides, thereby increasing the life of the operating components.
6. The specially reinforced head housing is split and positioned downward, ensuring it can be lifted to the left and right without interfering with the crusher rotor.
7. The head sprocket has 13-15 teeth, with odd and even teeth driven separately for increased service life.
8. The head sprocket is cut into three segments, allowing for teeth replacement without removing the chain plates for easy maintenance.
9. Transmission types include open, planetary, and suspended.
