What should I send for a screening or feeder parts quotation?

Send the part name and position, the equipment model as a compatible-with reference, key dimensions, quantity and delivery destination. Photos of the installed part and its mounting help when no reference is available. All brand names and model numbers are for reference only; parts are aftermarket replacements, not OEM.

How do I choose a material for screening and feeder parts?

Match the material to how the part wears: abrasion from the conveyed material, impact at the feed point, or corrosion in wet screening. State the material handled, whether screening is wet or dry, and where the old part wore, so the grade can be reviewed for that position.

How do I confirm size and fit?

Give overall dimensions, thickness, aperture or bar spacing where relevant, and the fixing method. If the part fits a specific deck or feeder section, name that section and add a photo of the mating surface.

Can you quote from a drawing or a sample?

Yes. Send the drawing with revision, or a sample with the dimensions that locate it on the machine. Modified apertures or spacings should be marked on the drawing so the change is quoted, not assumed.

What affects lead time and minimum order quantity?

Lead time depends on whether the part is a repeat item or needs new pattern, cutting or machining work, plus the agreed inspection and packing. There is no single minimum for every part; both lead time and minimum quantity are confirmed in writing per enquiry.

Screening & Feeder Parts

Overview

Feeder and screening assemblies consist of eight main categories of components that work together to ensure uniform material feeding, precise stratification, and efficient screening in industries such as mining, construction, and metallurgy. These components include the feeder body/frame, vibrator assembly, suspension assembly, drive system, feeder deck/grizzly sections, wear liners, fasteners and small parts, and various auxiliary devices. Proper selection, installation, and maintenance of each category are critical for reliable operation and long service life.

Materials

Key materials are chosen for their strength, wear resistance, and vibration performance:

Component Category	Materials	Function
Feeder Body / Frame	Carbon steel, alloy steel	Structural support; bears material load and vibration
Vibrator Assembly	Hardened steel shafts, bearings, seals	Generates controlled linear/circular/elliptical vibration
Suspension Assembly	Steel coil springs, rubber springs	Isolates vibration; limits displacement
Drive System (Belt & Hydraulic)	Rubber V-belts, steel pulleys, hydraulic motors	Transmits power to the vibrator
Feeder Deck / Grizzly Sections	High-manganese or alloy steel bars; wear liners	Feeds and stratifies material; screens oversize
Wear Components / Liners	Rubber, polyurethane (PU), ceramic inserts, UHMWPE	Protects contact surfaces from abrasion and impact
Fasteners & Small Parts	High-grade bolts, nuts, washers, pins, seals	Connects, seals, and secures assemblies
Other Components	Sensors, guards, auto-grease units	Safety, monitoring, and lubrication support

Feeding & Screening Mechanisms

Vibratory Feeding
Vibrators—either electromagnetic or mechanical with eccentric shafts—produce linear, circular, or elliptical motions that propel material along the feeder pan at adjustable amplitude and frequency.
Gravity Feeding
Inclined or apron feeders rely on gravity across a sloped surface, allowing bulk or hot materials to advance uniformly without vibration.
Grizzly Scalping
Grizzly sections, made of parallel steel bars or punched plates, remove oversized rocks and debris at the feeder inlet to protect downstream equipment.
Stratification & Screening
Screening decks—inclined, horizontal, or multi-slope—use vibration and slope to layer particles by size; fines pass through apertures while coarse particles travel over the deck.
Flow Control
Feed rate and stratification can be adjusted via variable-frequency drives on vibrators, amplitude settings, or changes in deck inclination to meet processing requirements.

Technical Glossary

Feeder Body / Frame: Welded steel structure supporting all feeder components.
Vibrator Assembly: Unit generating vibration, composed of eccentric shafts, gearbox, bearings, and housing.
Suspension Assembly: Springs or rubber elements isolating the vibrating frame from the support structure.
Drive System: Power transmission via V-belt or hydraulic motor to the vibrator assembly.
Feeder Deck / Grizzly: Panels or bar sections where material is fed and initially screened.
Liner Assembly: Wear-resistant panels protecting high-impact and high-abrasion areas.
Wear Plate: Removable panels made of rubber, PU, ceramic, or UHMWPE to shield equipment surfaces.
Lubrication System: Components such as grease fittings and auto-grease units ensuring proper oil or grease delivery.
Stroke: Peak-to-peak displacement of a vibrating component.
Stratification: The layering effect in screening where finer particles migrate downward.
Counterweight: Masses on vibrator shafts creating unbalanced centrifugal force.
Parallel Key: Keyed connection transmitting torque between shafts and pulleys.
Coupling: Device joining two shafts for power transmission.
Hydraulic Drive Unit: Vibrator drive option using a hydraulic motor and manifold.
Breather: Vent device on gear housings to prevent pressure build-up.
Lockout & Tagout: Safety procedure to prevent accidental equipment startup during maintenance.
Material Flow: Movement and path of material through feeding and screening equipment.
