Our Sink Float Tank is used to separate different materials based on their different specific weights. This is accomplished by feeding mixed materials into the tank, which is filled water. There are paddle rollers for pressing the materials down into water, mixing the materials fully with water and also moving this mix forward at a slow speed. Then, the floating materials …

The ability to sink or float is dependent upon the density of an object and it is the way the molecules are packed in an object that creates the opportunity to float or sink. Gravity plays a major role in whether an object will sink or float. Molecules make up everything and if the molecules are tightly packed together in an object, the density will be greater. These are …
