Abstract

Sand is the principal moulding material in the foundry as it is using for all types of castings. This paper an idea of testing tensile strength of sand which is using for castings in foundries with the help of load cell. Thi s system defines the sand whether it is good or bad for castings. We cannot check tensile strength of each grain of sand so; we form brick of that sand and then check tensile strength of that sand brick. Sand brick is placed in between load cell and DC mot or. DC motor continuously applies force on that brick till it breaks and at other side simultaneously load cell converts that force into electrical signal and analog ? to - digital converter converts that into digital and it displays on LED. Force at which po int brick breaks motor automatically stops that is the maximum tensile strength of that sand.
