S5X Series Vibrating Screen

S5X features circular‑motion trajectory. Screen box moves in quasi‑circular orbit to throw material upward‑forward for high screening efficiency for medium‑coarse aggregate. Linear screen performs reciprocating straight‑line motion and suits sand dewatering. Circular‑motion units deliver stronger excitation force and higher impact resistance for lump feed directly from crusher. Linear screens are preferred for dewatering after sand washing. S5X is not designed for heavy‑sludge dewatering and mainly serves dry or semi‑dry classification in crushing processes.

Excessive drop height from crusher causes violent material impact, accelerating mesh cracking and local fatigue damage of screen box. One‑sided impact leads to uneven material distribution, reduces screening efficiency and raises noise level. Install buffer chutes and baffle plates to absorb impact energy and spread material evenly across full deck width. Lower feeding height if possible. Avoid vertical heavy lump impact directly onto mesh surface to reduce shock‑related failures and extend service life of mesh and screen box.

S5X circular vibrating screen can be equipped with 1‑4 screen decks; deck quantity determines number of finished fractions. Single deck is for simple pre‑screening to remove large impurities. Two decks produce three material fractions. Three decks output four aggregate products. Four‑deck configuration realizes multi‑fraction fine classification. Upper decks adopt large apertures to retain lumps; lower decks use small apertures for fine‑aggregate separation. Select deck number according to product requirements. More decks increase overall height, requiring matched layout for chutes, hoppers and conveyors.

Poor efficiency and over‑size contaminants in finished goods are firstly checked against torn screen meshes. Then verify deck inclination and amplitude setting. High feed moisture and clay clog apertures and weaken sifting capacity. Biased feeding concentrating material on partial deck area also degrades classification performance. Adjust feed deflector for even material distribution, clean plugged apertures, replace damaged mesh, and re‑calibrate inclination and excitation counter‑weight to restore screening performance.

Smooth no‑load vibration but abnormal shaking under load is mostly caused by uneven material load. Biased feeding creates unbalanced load; partial mesh plugging leads to local material accumulation. Individual spring stiffness decay also produces force imbalance under material weight. Loosened or displaced vibrator eccentric blocks break excitation balance under working load. Shut down and inspect material distribution, mesh clogging, spring condition and eccentric‑block locking before resuming material‑feeding production.

Deck inclination angle of S5X screen is adjusted by modifying height of support spring seats, typical operating range 12‑20°. Larger angle accelerates material travelling speed and raises throughput yet shortens retention time and reduces classification accuracy. Smaller angle slows material flow for better sifting performance and higher precision at cost of lower hourly capacity. For closed‑circuit crushing, balance throughput and screening efficiency. Do not maximize angle blindly. Optimize setting according to particle size and feed moisture.
