When stones are quite large (more than 2 cm) or in a location that does not allow effective lithotripsy, a technique called percutaneous stone removal may be used. In this method, the surgeon makes a small incision in the back and creates a tunnel directly into the kidney. A tube is inserted and the stone is removed through this tube.

Bond Work Index

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test …

Crushing work index Calculation

The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushing test.

What is Compressive Stress?

When a solid body is stretched by applying two equal forces normal to the cross-sectional area, the resistive force developed per unit area is known as tensile stress; When a solid body is compressed, restoring force is developed due to an externally applied force. That restoring force per unit cross-sectional area is known as compressive stress.
