Overview

Recycling plant refer to metal recycling facilities and by-product processing.

Representative metal recycling facilities are aluminum recycling facilities and iron oxide recycling facilities.

Aluminum recycling facilities are beneficial to industry and the environment.

Since aluminum recycling is more than 90% energy saving than producing new aluminum,75% of the aluminum produced

so far has been recycled and is still in use today. To recycle aluminum, coatings such as paint, plastic, and oil must be

removed from the aluminum surface. By removing the coating material, aluminum recovery can be maximized due to reduce

metal loss and it also eliminates the risk of explosion by the coating in the aluminum recycling process.

More than 90% of this coating removal process is done through the kiln. The coated aluminum is supplied to the kiln and

heated above 1000 ° C. At this time, the volatile coatings are converted to the gaseous state from the hot kiln and removed

through the exhaust system, leaving only aluminum.

Iron oxide recovery facilities are used to recycle steel scrap.

Steel scrap is recycled using an electric furnace. In this process, steel dust is generated.

Generated Steel dust is stored in a closed silo, mixed with water, coke and lime and heated at 1200 ° C in a kiln.

At this time, volatile elements and impurities vaporize and escape through the exhaust system, and most of the reduced

iron is reoxidized by injecting clean air. The oxidized iron is recovered as iron oxide after cooling through the cooler.

By-product processing refer to treatment or recycling by solidification of various by-products from the life or industry.

Sludge is a by-product from the typical wastewater treatment process and is recycled as a fertilizer on the farm after

treatment, or reused in the field as part of energy recovery.

1. The steel dust is transferred to a recycling plant in dry, wet or pellet form and stored in a silo.

2. Wet materials are preheated, dried and heated as they pass through the kiln and then chemically react at about 1200 ° C.

3. The vaporized metal oxide is treated in the exhaust gas system, the coarse particles are returned to the kiln and the fine particles are
