Comprehensive utilisation of dedusting ash
Category: Products
Liujing Technology Group using independent property rights technology, the foundry dust ash free sintering made of functional particles, which made of free sintering ceramic granules can be used to replace stone for the production of green permeable building materials, ceramic sand and other products, and the formation of a better marketable products. For the foundry enterprises to achieve the solid waste ‘zero emission’.
Technical features and advantages
● Liujing Technology Group has a number of patented technologies and innovations in the field of dust ash utilisation, and the ‘Foundry Dust Ash Utilisation Technology’ scientific and technological achievements have been appraised as ‘leading in China’.
● Liujing Technology Group has drafted the China Foundry Association's group standard ‘Technical Guidelines for the Recycling ofSand Casting Waste (Old) Sand and Resourceful Utilisation of Dust Removal Ash’, and these technological achievements have provided strong support for the sustainable development of the enterprise.
