Typical Applications & Industries
This machine is the first line of defense in your crushing plant. It is widely used in:
- Mining & Quarrying: Feeding large, sharp run-of-mine (ROM) rocks into the Primary Crusher (Jaw/Gyratory).
- Cement Plants: Transporting high-temperature hot clinker from the kiln.
- Metallurgy: Handling heavy iron ore or copper ore with high bulk density.
- Construction Waste: Moving concrete slabs and rebar without jamming.
Capacity & Series Classification
We classify our feeders based on impact resistance:
- Light-Duty (GBZ Series): For material density < 1200kg/m³, block size < 160mm. Ideal for chemical or small aggregate plants.
- Medium-Duty (GBL Series): For density < 2400kg/m³, block size < 400mm. Common in general mining.
- Heavy-Duty (GBZ Series): For density > 2400kg/m³, block size > 1000mm. Built for the toughest primary crushing stations.
- Throughput: Ranging from 50 t/h up to 2000 t/h.

Structure Design & Material Selection
- The Pans (Plates): Made of High Manganese Steel (Mn13). These plates work-harden under impact, meaning they get tougher the more rocks hit them.
- The Chain: We use standard Excavator Track Chains (Crawler Chains). They are maintenance-free, incredibly durable, and parts are easy to source globally.
- The Drive: Equipped with a frequency converter (VFD) to adjust feeding speed precisely based on crusher load.
Structure Design & Material Selection
- Belt Feeder: Good for sand, soil, and small stones. Cheap but fragile.
- Apron Feeder: Essential for sharp rocks (which slice belts), heavy boulders (which crush idlers), and hot materials (which melt rubber).
- Vibrating Feeder: Good for screening, but cannot handle wet/sticky material (it sticks to the pan). Apron feeders force sticky material forward.
Customization Options
- Inclination: Can be installed horizontally or at an angle up to 25 degrees to save pit depth.
- Hopper Design: We design the feed hopper with wear liners to match your truck dumping height.
- Spillage Control: Optional dribble belt underneath to collect fine particles that fall between plates.
Installation & Maintenance
- Modular Design: The head, tail, and intermediate sections are bolted, making it easy to ship in containers and assemble on-site.
- Easy Chain Tensioning: Features a screw take-up device at the tail to keep the chain tight and prevent skipping.
FAQ
Q: Can it handle sticky clay or wet ore?
A: Yes. Unlike vibrating feeders that lose efficiency with wet mud, the Apron Feeder provides positive displacement-it physically pushes the mud forward with strong traction.
Q: How long do the plates last?
A: With proper maintenance, our Manganese Steel plates typically last 3-5 years even in harsh mining conditions.
