FAQ
Q1: What is the difference between a vibrating feeder and a vibrating screen?
A: The core function of a vibrating feeder is uniform material conveying, with optional coarse screening; the core function of a vibrating screen is particle size classification, without feeding function. Feeders are installed below silos, while screens are installed after crushers.
Q2: How to choose between dual-motor vibrating feeder and eccentric shaft feeder (such as ZSW series)?
A: Dual-motor direct drive type has simple structure, convenient maintenance, and low energy consumption, suitable for small and medium-scale production lines; eccentric shaft + gear transmission type has greater excitation force and larger feeding size, suitable for heavy-duty mining conditions.
Q3: How to handle sticky material adhesion to trough?
A: Recommendations: ① Increase trough inclination to 15-20°; ② Add polyethylene or polyurethane anti-stick liners; ③ Configure air cannon blockage removal device; ④ Select high-frequency vibration motors (25Hz) to reduce adhesion.
Q4: How to precisely control feeder capacity?
A: Change excitation force by adjusting vibration motor eccentric block angles (100% excitation force at 0° angle, minimum at 180°), or use variable frequency controller to adjust motor speed to achieve stepless speed regulation.
Q5: How long do trough wear liners last? How to replace?
A: When processing medium-hard materials like limestone, 16Mn liners last about 2,000-3,000 hours; when processing hard rock like granite, recommend NM400 wear-resistant plates with service life up to 4,000 hours. Liners are bolt-fixed, 2 workers can complete replacement within 2 hours.
Q6: How to handle excessive equipment operating noise?
A: Standard models have noise ≤75dB(A). If exceeded, please check: ① Whether spring supports have failed; ② Whether trough collides with surrounding structures; ③ Whether motor bolts are loose. For lower noise requirements, optional soundproof covers available.
