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.
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 |
