crushing quartz with ultrasound
microstructural observations that grain crushing in sand-stone is generally characterized by extensive microcracking as cracks nucleate and propagate when pressure reaches the critical pressure P*. Therefore these newly formed cracks may induce a decrease in elastic wave velocities. Second, Zhang et al. [1990], Wong et al. [1997], and Karner et al.

Ultrasonic wave velocity and compressive strength of an early age concrete containing high volume fly ash were very low. However, it was observed that both values indirectly increase with the increase in curing time. Rocks taken from a quarry near the Antalya are crushed into desired sizes by stone crusher, so the aggregate was formed.

The use of ultrasonic cavitation for kidney stone crush. Large kidney stones can obstruct the urethra and cause severe pain or infection. Current non-invasive approach for kidney stone crush called extracorporeal shock wave lithotripsy ( ESWL) has been employed since 1980. In ESWL, multiple shock waves with various pulse repetition frequency

ESWL ( extracorporeal shock wave lithotripsy) A technique for shattering a kidney stone or gallstone with a shock wave produced outside the body. There are several methods available for producing an acoustical or ultrasonic " big bang " which can be focused from outside onto the kidney and the kidney stone. The stone breaks up after 800 to 2000

A method in which crushing of a kidney (or ureter) stone is achieved by focusing a shock wave on it from the outside. By the types of energy used, the following types of lithotripters are distinguished: Piezoelectric; Electro-hydraulic ; Electro-magnetic. Focusing the shock wave on the stone is carried out using ultrasound or under X-ray.
