Waste Slag Resource Utilization Processing Line
Designed for municipal solid waste (MSW) incineration bottom ash recycling, the production line efficiently recovers ferrous and non-ferrous metals while producing high-quality recycled aggregates for eco-friendly construction materials, maximizing resource recovery and minimizing landfill disposal.
Waste Slag Resource Utilization Processing Line
With the rapid growth of the Municipal Solid Waste (MSW) Waste-to-Energy (WTE) industry, Incineration Bottom Ash (IBA) has become one of the major solid by-products generated during the waste incineration process. Bottom ash typically accounts for 10%–30% of the total waste incinerated and mainly consists of slag, glass, ceramics, sand, stones, metals, and small amounts of unburned organic matter.
Bottom ash contains valuable recyclable metals such as iron, copper, aluminum, and stainless steel, while its non-metallic fraction possesses excellent physical properties that make it an ideal raw material for producing environmentally friendly construction materials. Through advanced recycling and separation technologies, bottom ash can be effectively processed to achieve waste reduction, harmless treatment, and resource recovery, significantly reducing landfill disposal, improving resource utilization, and promoting the development of a circular economy.
Runding Intelligent specializes in complete Waste Slag Recycling Solutions, providing one-stop turnkey EPC services covering process design, equipment manufacturing, installation, commissioning, technical support, and operation services. We help Waste-to-Energy plants maximize resource recovery, improve operational efficiency, and create greater environmental and economic value.

The equipment remains logically online to customer application systems even when disconnected from the network. Users can read historical operating status offline and preset device parameters, which will be automatically executed once the network re-establishes connection.2. Remote Equipment Control & Operation
The remote communication function of runding intelligent gateway collects PLC data to monitoring terminals (PC, iPad, etc.). The client tool installed on monitoring terminals builds a dedicated secure channel connecting to runding intelligent gateway. Users can rapidly filter and convert equipment data according to self-defined business rules and execute localized operations on the collected data.

Scraper Conveyor
It is widely used in electronics, machinery, food, printing, tobacco, plastic and other industries for assembly, inspection, packaging and material transfer. It also acts as an ideal high-efficiency continuous conveying machine for furnace slag treatment production lines.
Equipment Overview
Identical to the general introduction above: The scraper conveyor is a universal transport machine for assembly, testing, packaging and logistics across multiple industries, and it is also a perfect continuous conveying solution for furnace slag processing systems.
Working Principle
The closed-loop chain is driven by head driving shaft and tail passive shaft with guide rails and pressure plates installed in the middle. Power drives the head shaft to pull the chain-mounted scrapers forward, which push materials on the base plate toward the discharge outlet to complete continuous conveying.
