Heavy Duty Apron Feeder
Our Heavy Duty Apron Feeder uses frame, drive unit, main shaft unit, chain, chain plate, tail tension device and supporting rollers. Supporting roller body and shaft use 40Cr forged steel with HRC50-55 surface hardness and hardened depth not less than 3 mm.
Product Introduction
Heavy Duty Apron Feeder are widely used in mining, metallurgy, building materials, coal and other industrial areas. They are applicable to short-distance transportation of large lump materials, commonly installed at large concentrators to deliver stock from storage bins to primary crushing equipment in continuous, uniform and adjustable feeding mode. The machine also realizes short-distance material conveying. Especially when fitted under hoppers, the feed plate bears heavy direct load from bulk material pressure. It works well for both coarse and fine-grained materials and withstands harsh working conditions. It features strong adaptability against fluctuations in material granularity, component makeup, temperature, viscosity, as well as frost, rain, snow and frozen feedstock. It can be mounted horizontally or at an inclined angle.

Components
1. The Heavy Duty Apron Feeder frame carries the feeding load and supports the drive and tail tension areas.
2. Drive unit and main shaft unit transfer power to the chain and chain plate.
3. Chain and chain plate carry bulk material from the bin discharge area to the next equipment.
4. Tail tension device keeps the chain running with proper tension.
5. Supporting rollers carry the moving chain plate under heavy-load service conditions.
Product Advantages
The feed plate can bear direct pressure from bulk material when the feeder is installed under a hopper.
01
The machine supports continuous, uniform and adjustable feeding before primary crushing equipment.
02
Supporting roller body and shaft are made from 40Cr forged steel, with HRC50-55 surface hardness and hardened depth not less than 3 mm.
03
Four-piece chrome-plated floating oil seals are used, and the assemblies undergo underwater pressure tightness test to block dust and silt ingress.
04
Oil bath lubrication is pre-filled before delivery, so periodic manual grease replenishment is not required during normal use.
05
Main Applications
1. The Heavy Duty Apron Feeder is used below storage bins and before primary crushers in concentrators.
2. It is used for short-distance transportation of large lump materials and heavy bulk feed.
3. It is suitable for mining, metallurgy, building materials, coal and similar industrial feeding sections.
FAQ
Q: Can it handle both coarse and fine-grained material?
A: Yes. The reference description states that it works for coarse material and fine-grained material.
Q: Can it be installed at an incline?
A: Yes. It can be mounted horizontally or at an inclined angle.
Q: What is the supporting roller material?
A: The supporting roller body and main shaft are forged from 40Cr steel.
Q: Why is the Heavy Duty Apron Feeder suitable under a hopper?
A: The feed plate bears direct pressure from bulk material, so the structure is suited to heavy-load feeding below storage bins.
