Glass industrial waste refractory recycling technology

The European glass industry uses more than 100,000 tons a year for masonry kilns, which have a useful life of 5 to 8 years. The demolition of these kilns will generate thousands of tons of abandoned refractory materials, most of which will be sent to CETs or proprietary dumps.



To help users reduce the amount of waste refractory materials sent to landfills, the company is working with glass companies and kiln dismantling companies to establish standards for waste acceptance and to develop new products made from recycled materials.

At present, 30% to 35% of the silica bricks removed after the end of kiln service can be reused to make two other types of silica bricks, including siliceous wedges and light insulation Silica brick. The first European facility to comprehensively recycle spent refractory refractories specialized in the disposal of waste refractories from the glass industry, steel industrial furnaces, incinerators and chemical industries with a recovery of 90%.

Glass company will melt the wall of the kiln pool to cut the whole, re-use the effective part of the pool wall has been successful, and the ZAS brick surface with the glass removed after the use of quenching the brick crack, crushing, grinding, After screening different size fractions of aggregate and fine powder, used to produce cheap high-performance castable and iron ditch material.
