Industrial Coal Shredder for Stoker Boiler Feed
Product Overview
Our industrial coal shredder for stoker boiler feed is engineered to turn oversized coal chunks, briquettes, and waste material into a uniform, low‑size feed that guarantees smooth combustion in stoker‑type boilers. Designed for continuous operation in high‑temperature environments, the shredder delivers consistent particle size reduction while minimizing wear and downtime. Ideal for power plants, cement factories, and large‑scale heating facilities, this machine integrates seamlessly with existing feed systems to boost thermal efficiency and reduce fuel handling costs.
How It Works
The shredder employs a twin‑shaft, high‑torque drive that pulls coal through a series of hardened steel rotor knives. Each rotor rotates at a calibrated speed to produce a target particle size of 10‑30 mm, optimal for stoker burners. An integrated vibration‑dampening frame isolates the unit from boiler vibrations, while a sealed lubrication system extends bearing life. The optional dust‑extraction port can be connected to a cyclone separator, ensuring a clean feed and a safer workplace.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a customized industrial coal shredder for stoker boiler feed?
We accept single‑unit orders for prototype or pilot projects. For volume production with standard specifications, the MOQ is typically 5 units, allowing us to optimize tooling and shipping costs.
Can the shredder be adapted to different coal types or alternative solid fuels?
Yes. The rotor knife geometry and clearance can be adjusted to handle lignite, bituminous coal, or biomass briquettes. Material‑specific wear plates are available on request.
What is the typical lead time from order confirmation to delivery?
Standard models ship within 15‑30 days. Fully customized configurations require 30‑45 days, depending on engineering revisions and tooling.
Do you provide warranty and after‑sales support?
All units come with a 12‑month comprehensive warranty covering parts and labor. Our technical team offers 24/7 remote diagnostics and on‑site assistance for critical failures.
