Processing Incineration Bottom Ash (IBA) from Waste-to-Energy (WtE) plants presents unique challenges. Unlike standard ores, IBA contains a high percentage of moisture, highly abrasive materials (glass, ceramics), and agglomerated (fused) clumps that trap valuable non-ferrous and ferrous metals.

Our IBA Specialized Crusher Series is engineered specifically for solid waste resource recycling. By effectively breaking down slag conglomerates from 0-200mm down to your desired uniform size, our crushers expose trapped metals, directly boosting the recovery rates of downstream magnetic and eddy current separators.

Core Equipment in Our IBA Crushing Line

We offer three distinct crushing solutions to match the specific moisture content and material composition of your municipal solid waste (MSW) slag.

1. Heavy-Duty Hammer Crusher (For Primary Bottom Ash Sizing)

Ideal for primary sizing of dry to semi-dry bottom ash. It uses high-impact force to break apart brittle slag, glass, and concrete structures.

Highly Abrasive Resistant: Equipped with newly developed alloy-cast hammerheads designed specifically to withstand the severe abrasion of MSW bottom ash.
Easy Maintenance: The top-cover access design allows for rapid replacement of worn hammers, minimizing plant downtime.
Adjustable Output: Independently adjust the discharge grate (coarse, medium, fine) to ensure uniform sizing, optimizing the feed for subsequent Trommel Screens.

2. Specialized Metal Crusher (For Ferrous & Scrap Liberation)

Specially calibrated for zones with high scrap metal concentrations, ensuring effective liberation of metals from slag.

Scrap Metal Processing: Effortlessly crushes through 0-200mm metal-heavy feed, breaking the bonds between fused slag and scrap iron.
Enclosed Environmental Design: Optimized sealing structure effectively controls the noise and dust typically generated during intense metal crushing.

3. Twin-Shaft Shredder (For Wet, Sticky, and Agglomerated IBA)

The ultimate solution for high-moisture, sticky bottom ash that clogs traditional crushers.

High-Torque Shear Crushing: Utilizes mutual shearing, tearing, and squeezing at low speeds and high torque. Perfect for viscous and dirty materials.
Anti-Clogging Three-Box Structure: The innovative upper and lower toothed knife design actively prevents wet ash build-up, ensuring continuous, stable operation.
Fine Granularity Output: Capable of reducing bulky slag down to a fine 20mm, the ideal input size for maximizing aluminum and copper extraction in Eddy Current Separators.

Frequently Asked Questions (FAQ)

Q: How do your crushers handle wet and sticky bottom ash without clogging?

A: For high-moisture IBA, we strongly recommend our Twin-Shaft Shredder. Its low-speed, high-torque shearing action, combined with a specialized knife design, actively cleans the shafts during operation, preventing the agglomeration and clogging common in traditional impact crushers.

Q: What is the ideal discharge size for recovering non-ferrous metals?

A: To maximize aluminum and copper recovery using an Eddy Current Separator, the IBA should ideally be crushed to a uniform size of 0-20mm or 20-40mm. Our crushers feature adjustable discharge settings to precisely match these downstream requirements.

Q: How often do the wear parts need replacing when processing abrasive MSW slag?

A: Incineration bottom ash contains high levels of abrasive glass and ceramics. To combat this, our crushers utilize high-chromium cast alloys and one-piece casting techniques. While replacement frequency depends on your exact daily tonnage, our easy-access housing reduces maintenance time by up to 40% when replacements are needed.
