Sand Screening And Washing Machine

Abstract

In recent years the foundry industry has been showing an increased interest in Screening and washing of sands. Deposits of sand and gravel, the unconsolidated granular materials resulting from the natural disintegration of rock or stone, are generally found in near-surface alluvial deposits and in subterranean and subaqueous beds. Sand and gravel are siliceous and calcareous products of the weathering of rocks and unconsolidated or poorly consolidated materials. Grain shape, screen analysis, chemical characteristics, as well as thermal characteristics, must be uniform to get uniform properties in today's sand mixes. We are in a process of developing a concept which has the capability to bring revolution in the field of construction in most developing nations of the world. We present here our concept of "sand screening and washing”. This project is a combination of basic principles called as screening and washing which is being used for many centuries in the field of construction all around the world.
