Recycling Technology, Materials, and Processes
As the world’s leading manufacturer of screening machines, we offer the best screening results for your processing of steel mill slag, municipal solid waste incineration ash—such as grate ash and fluidized bed ash—and much more…
SPALECK screening machines and conveying systems play an indispensable role in the processing of slag from steel mills and waste-to-energy plants. We not only enable you to efficiently recover metals—both ferrous and non-ferrous—but also to precisely separate the wide variety of other components and raw materials, ensuring smooth recycling and reintroduction into the economic cycle. With over 150 years of experience in mechanical engineering, SPALECK is your reliable partner for efficient slag processing—benefit from our expertise and put your trust in quality!
The composition of grate ash and fluidized-bed ash from waste-to-energy plants—often referred to as waste-to-energy slag—can vary significantly depending on the type of waste incinerated. One of the goals of processing is to recover valuable non-ferrous metals.
Depending on the raw materials used during steel production, steel mill slag has different properties regarding to raw material recovery in slag processing. For this reason, we develop the screening machines optimally tailored to your application!
SPALECK Conveyor and Separation Technology plays a key role in the optimal recycling of non-ferrous metals by ensuring a uniform feed to downstream sorting equipment and the precise separation of MV slag and metals.
The SPALECK ActiveFEED provides optimized and consistent slag feeding for recycling lines, with maximum ease of use and automatic regulation to ensure consistent performance, with a capacity of 3–25 m³.
SPALECK finger screens and bar screens are designed for efficient coarse screening and pre-separation of slag, with maximum output, minimal wear, and clog-free operation.
With the SPALECK recycling screen, you’ll achieve the best results in the classification of slag and municipal solid waste (MSW) ash, thanks to optimal screening quality, performance, and reliability.
The SPALECK tensioned-shaft screen is designed for the cost-effective fine screening of materials that are difficult to screen, sticky, and moist—such as slag and municipal solid waste ash—with mesh sizes ranging from 1 mm to approximately 50 mm.
The high-performance SPALECK 3D Combi, featuring a 3D upper deck and a tension-shaft lower deck, combines unmatched efficiency and cost-effectiveness with optimal screening results—producing up to 5 screen fractions—in your slag processing operations.
The ActiveCLEAN vibrating conveyor trough actively prevents damp material flows, such as grate ash, from sticking and caking, thereby completely eliminating downtime and the need for cleaning.
Every year, we conduct hundreds of material tests with our customers at the SPALECK TestCenter. The goal: Optimal classification and material feed to ensure the best performance of the downstream sorting equipment.
We’d be happy to advise you on your free trial day at the SPALECK TestCenter. Our goal: To find the best solution for your recyclable materials.
Due to the high moisture content of the slag and bottom ash, caking and sticking occur in the processing procedure. This requires a great deal of cleaning work and repeatedly leads to production downtimes. With SPALECK ActiveCLEAN, you can avoid these downtimes and maximize your system availability.
