Slag Recycling Application

Slag is a partially vitreous by-product of the process of smelting ore to separate the metal fraction from the unwanted fraction. In nature, the ores of metals such as iron, copper, lead, nickel and other metals are found in impure states, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed. Slag can be recycled for producing aggregate, concrete, cement and ballast for many construction applications.

Foundry Slag Recycling Operation

Industrial solid waste recycling has been a crucial practice to the natural resource protection, in the cost and environmental impact reduction. As result of that, the foundry slag recycling as raw material in pavement, concrete and cement are already common practices, where the noblest use of this material depends on the existence of adequate characteristics to the proposed use.

The industrial waste produced by aluminum, steel, and iron foundries result in spent foundry sands. Foundries require new sand for casting molds, and the foundry slag can be recycled several times while maintaining its effectiveness. However, mechanical abrasion and heat will render the sand unusable over time, and a certain percentage of the total sand is continuously removed from production and replaced with new sand. The spent or unusable foundry sand is typically disposed of at a landfill.

Slag Recycling Plant

The slag recycling plant is equipped with hydraulical control system, which can immediately retract on entry of non-crushables (such as tramp metal) into the crusher. The hydraulic control system offers a further big advantage in that the gap setting between the blow bars and impact aprons (which determines the overall product granulometry) can even be re-adjusted whilst the machine is in operation. In contrast to the previous models, the latest machine is equipped with a new labour-saving blow bar retention system, so that blow bar changing becomes even quicker and more simple.
