Zenith's sand making machinery has a good reputation around the world. Meanwhile, with the reduction of natural sand resources, quarry owners are eager to find efficient mining machines to produce high grade sand. Here we focus on one of project cases in UAE, taking the sand making plant for example. Of course, we can also help our customers design and install the entire set of sand production line.Today, the construction market has a large demand for better aggregate shape.
For the water shortage area of sand manufacturers, in the production process, water demand will undoubtedly give the entire production line with a lot of trouble. Especially for some of the gravel plant, concrete mixing stations and other industries, because of the sand washing equipment is relatively backward mechanism, the finished sand often need to the washing operation, so as to meet the sand industry standard. For some manufacturers, the lack of water resources makes them have to invest a lot of money to solve the problem of their own water use.

However, a proactive policy of public engagement was initially not followed in the case of the LAMP Kuantan site. Indeed, with RE sites, the importance of public engagement has now become more acute because the wider public has started to associate RE with nuclear residues following greater Malaysian activism and their alliances with European and Japanese anti-nuclear groups. Some lessons regarding how to approach public engagement in this particularly polarized context can be learned from the Republic of Korea.
