What discharge moisture content can I expect from the TS dewatering screen?

Discharge surface moisture depends on feed gradation, feed rate relative to the model’s rated capacity, and screen aperture. For washed sand and aggregate (0.15 mm and coarser) operated within the rated capacity range, typical discharge moisture is 12–18%. For very fine material (sub-0.15 mm), moisture content tends toward the upper end of this range or […]

Which screen media type is best for my application?

For dry aggregate classification (limestone, granite, basalt) at apertures above 10 mm in normal operating conditions, welded wire panels offer accurate aperture and good open area. For wet screening, fine apertures (below 10 mm), or feeds with high clay content where blinding is a persistent problem, polyurethane panels are the standard recommendation – their flexibility prevents […]

Why is Q345R steel specified instead of the Q235 used by many competitors?

Q235 is a general structural steel with a yield strength of 235 MPa and relatively low notch toughness. Under the high-cycle fatigue loading of a vibrating screen (typically 800–900 vibrations per minute, 24 hours per day), Q235 side plates are prone to progressive crack propagation from weld toes and bolt holes – the dominant failure mode […]

What is the difference between 2YK and 3YK models – when should I choose three decks?

The 2YK prefix denotes a two-deck (two-layer) screen producing three fractions (oversize, mid-size, and undersize); 3YK denotes a three-deck screen producing four fractions. Choose three decks when the process requires simultaneous separation at three cut points – for example, producing 0–5 mm, 5–20 mm, 20–40 mm, and +40 mm fractions from a single machine. Two decks […]

Can the SP series handle wet or sticky materials?

Yes, with appropriate installation angle and trough lining. For materials with moisture content above 8–10% or with cohesive properties (fine limestone, moist coal, clay-bearing ore), specify a downward installation slope of 5–10° and a smooth-surface trough lining – either polished stainless steel or polyurethane – to minimize adhesion. For extremely cohesive materials above 15% moisture, combine the […]

How is the feed rate adjusted on an SP vibrating feeder?

Feed rate is adjusted by changing the vibration amplitude via the excitation mass setting on the vibration motors. Most SP motor configurations allow the eccentric mass position to be adjusted in discrete steps at the motor end, increasing or decreasing the resultant force and therefore the trough amplitude. For continuous variable control – required in automatic […]

What installation angle is recommended for the SP series?

For batching, proportioning, and automatic-control applications, horizontal installation (0°) is recommended to ensure uniform, gravity-independent feed rate and to prevent uncontrolled material flow when the motors are stopped. For general continuous feeding applications where a slight gravity assist is acceptable, a downward slope of up to 5–8° increases conveying velocity and is preferred for dry, […]

How often do the exciter bearings require lubrication?

The exciter shaft bearings are grease-lubricated via external nipples and require re-greasing every 200–300 operating hours under normal conditions – more frequently in high-dust or high-temperature environments. We recommend using a lithium-complex grease with an NLGI Grade 2–3 rating and an operating temperature range above 120°C. Full bearing replacement intervals depend on load and duty but […]

Can the installation slope be set to zero for a flat-floor installation?

Yes. The ZSW series is rated for installation slopes of 0° to 5° (downward toward discharge). A 0° slope is suitable for most standard installations where the primary crusher is at grade. A slight positive slope (2–5°) increases the conveying velocity and is preferred for high-moisture, sticky feeds that resist gravity-assisted movement on a flat […]
