C6X Jaw Crusher is new equipment used for crushing hard or abrasiveness stones. It is possess of detachable frame without welding structure, double wedge adjusting device, elastic limit damping device and integrated motor seat, which will make C6X Series Jaw Crusher popular in the market.
HPT Series High-Efficiency Hydraulic Cone Crusher combines crushing stroke with crushing chamber perfectly, which makes capacity improved and efficiency increased. Besides, hydraulic lubrication control system helps bearing of hydraulic cone crusher get double protection.
Based on more than 30 years of experiences, VSI6X Series Vertical Shaft Impact Crusher carrying many patents amazes the market greatly. This machine is possess of four openings impeller, special sealing structure and sealed cartridge bearing structure, which makes production convenient and efficient.
A, Stone engaged within a basket. B, Stone removed with a wire basket. During stone extraction, withdrawing with a fully opened basket (trawling) is less effective, as the loose basket wires tend to cut across the sphincterotomy rather than along the axis of Stone Fragmentation and Extraction SpringerLink,14.2 Strategies of Stone Fragmentation and Extraction. There are two main strategies available: The first consists in vaporizing the stone, washing the debris out Grande G. et al., : Dilation assisted stone extraction ,Dilationassisted stone extraction (DASE) is the combination of two techniques: EPLBD and submaximal EST.

A critical step to obtaining successful stone extraction is to provide an adequate opening for the stones that are to be removed by endoscopic sphincterotomy alone, endoscopic papillary balloon dilation (EPBD) alone, or a combination of both. In more than 90% of cases, conventional treatment is based on endoscopic sphincterotomy (EST) withDilation assisted stone extraction for complex biliary ,Europe PMC is an archive of life sciences journal literature.Foods Free FullText Rapid SolidLiquid Dynamic ,Traditionally, solidliquid extractions are performed using organic and/or inorganic liquids and their mixtures as extractant solvents in contact with an insoluble solid matrix (e.g., the Soxhlet method) or using sequential atmospheric pressure systems that require long procedures, such as maceration or percolation. The objective of this
Soxhlet extraction is a simple and effective method. It has been used for a wide range of samples like soils, sediments, and animal and plant tissues. A wide variety of solvents like dichloromethane (DCM), pure or mixed with acetone or hexane, and acetone–hexane mixtures can be used. The use of nonpolar solvents only is not recommended.Microwave assisted extraction of phytochemicals an ,extract and a particular metaboilite by microwave assisted extraction method was higher with increased power levels of microwaves from 30150 W, it was further reported that extraction efficiency was improved for short duration of irradiation by setting higher power levels (Shu et al., 2003; Desai et al., 2010).

The principle behind solvent extraction is extremely basic. The goal is to use a liquid ( solvent) to dissolve ( solvate) a target molecule or group of compounds ( solute) and to wash them out of the solid plant material. The solvent is then separated from the solute in order to concentrate the solute. This separation is usually achieved byPrinciples and methods of extraction unacademy,The most used methods of extraction are maceration, reflux extraction, and percolation, which frequently use organic or natural solvents and are in the requirement of large quantities of solvents and take much time in extraction. The natural methods of extractions have a variety of modern and more organic methods, such as pressurized Stone Fragmentation and Extraction SpringerLink,14.2 Strategies of Stone Fragmentation and Extraction. There are two main strategies available: The first consists in vaporizing the stone, washing the debris out through the Amplatz sheath, or aspirating the sand with the ultrasonic probe or with a combined device (like CyberWand or Swiss LithoClast Master).
About this book. Natural products are sought after by the food, pharmaceutical and cosmetics industries, and research continues into their potential for new applications. Extraction of natural products in an economic and environmentallyfriendly way is of high importance to all industries involved.

It can capture and withdraw stones. The balloon catheter can capture small stones by obstructing the bile duct lumen after distention. That cannot prevent the moving of small stones to be impacted in the corner pocket at the lower end of the cystic bile duct during stone extraction.
