Novel Counter Flow Classification System for the sustainable grading of high value industrial sands-RICHSAND

沙是地球上仅次于水的第二种最常用的自然商品。在人类的时间尺度上，它也是一种不可再生的资源。RICHSAND项目解决了开发更高效、更具成本效益和更可持续的材料回收的迫切需求，这些材料回收严格指定等级的普通砂和再生砂，以满足不断增长的人口和高附加值制造市场的需求。该项目专注于开发一种新的、大规模的创新工业设备和工艺，该设备和工艺使用流动的水，在高度可控的条件下，有效地分离和分类工业体积的沙粒尺寸。这种高价值市场的例子是我们的基本基础设施(如桥梁、住房)的建设(如水泥)、制造业(如玻璃、陶瓷)、水过滤和我们的休闲产业(高尔夫、马术、景观美化)所需的砂。牵头申请者CDEGlobal Ltd.已经完成了对这一新工艺的初步研究，现在将与主要顾问一起应对建立和测试工业规模系统的技术挑战，以确保先进的沙子分类或分类是实用、高效、安全和经济的，同时减少对环境的影响。该项目支持英国循环经济对宝贵自然资源的再利用、回收和补救，同时确保制造业的可持续供应链。

Sand is the second most used natural commodity on the planet after water. It is also a non-renewable resource over human timescale. The RICHSAND project tackles the _urgent need_ to develop a more efficient, cost effective and sustainable material recovery of tightly specified grades of general and recycled sands needed to meet the demands of growing populations and high value manufacturing markets. The project is focused on the development of a new, large scale, innovative industrial equipment and process, which uses flowing water, under highly controlled conditions, to efficiently segregate and classify the grain size of industrial volumes of sand. Examples of such high value market are sands are those needed in construction(e.g. Cement) of our basic infrastructure (e.g. bridges,housing), manufacturing (e.g. glass, ceramics) water filtration and our leisure industries (golf,equestrian,landscaping). CDEGlobal Ltd. the lead applicant has completed preliminary research on this new process and now together with key consultants will meet the technical challenges of building and testing an industrial-scale system to ensure that the advanced sorting or classification of the sand is functional, efficient, safe and economic while reducing environmental impact.This project supports the UK circular economy in the reuse, recycling and remediation of valuable natural resources while ensuring a sustainable supply chain for manufacturing industries.
