1.1 Principle. Crushing is used to very quickly produce a fine powder from a bulk material or fine particle using mechanical crushing. This technique is essentially used to investigate ceramics, minerals, and mixed–composite materials. Materials must be brittle or made brittle and of a high hardness to average hardness.

Abstract. The double kissing crush (DK crush) is the most studied two-stent coronary bifurcation stenting strategy. While published data support its use, DK crush can be challenging to perform. In this review we provide a detailed step-by-step description and troubleshooting for each stage of the DK crush technique.

In classic crush, the SB stent is deployed first, with deliberate proximal protrusion 4 to 5 mm into the MV (Figure 1A).The technique was soon refined to include kissing balloon inflation (KBI) (Figure 1B), which resulted in lower rates of restenosis (9).The CACTUS (Coronary Bifurcations: Application of the Crushing Technique Using …

Paralleling Technique (Disadvantages) When comparing the paralleling and bisecting angle techniques, the paralleling technique is: 1. Less comfortable. Because the film is usually more upright when using the paralleling technique, it impinges more on the palate or floor of the mouth, thus making it more uncomfortable.

5. TECHNIQUES • The bristles are placed at a 45 angle to the gingiva and moved in small circular motions. • Strokes are repeated around 20 times,3 teeth at a time. • On the lingual aspect of the anterior …

Fast tracking vs Crashing: Nature of application. Fast-tracking is the first step in schedule compression and involves planning parallel execution or overlapping of activities to shorten project timelines, whereas crashing involves the addition of resources to the project to complete twice as much as the planned work in the same amount of time.

• Convenience of handling the ore and its transportation. • Preparation of feed material for different ore processing techniques ( Eg:- granular material for gravity separation, fine particles for froth flotation etc.) . Difference between crushing and grinding- Crushing ( dry) - Size reduction occurs preferentially on large fragments.

S. This document discusses methods and techniques for ashing samples to determine their mineral content. It describes: 1) Dry ashing, which uses high temperatures in a muffle furnace to burn off organic matter, leaving mineral residues. Most minerals are converted to oxides, sulfates, or silicates. 2) Wet ashing, which uses acids and oxidizing ...

4. 2. Definition of in-pit crushing and conveying (IPCC) system A continuous processing system that includes the shovel, crusher, spreader and all appropriate conveyors that reduces rock of mine (ROM) to a conveyable size. In fact, IPCC is the use of fully mobile, semi-mobile or fixed in-pit crushers coupled with conveyors and spreaders …

INTRODUCTION. Bifurcation lesions account for 15–20% of all percutaneous coronary interventions (PCIs). 1) Coronary bifurcation stenting is still complex and associated with a high risk of stent thrombosis and restenosis even in this era of drug-eluting stent (DES). 2),3) Provisional approach (1-stent technique) has been proved to …

3 Techniques for Efficient Concrete Curing. Many factors affect the rate at which water evaporates from freshly placed concrete. This includes air temperature, humidity, concrete temperature, and wind speed. As a result, there are many techniques to help concrete retain moisture at early ages. These methods can:

• Material is fed between the plates and is reduced by crushing and shear • Mills with different patterns of grooves, corrugations on the plates perform a variety of operations • Overfeeding – lowers grinders performance – Increases heat generation during milling • Disks are 20-137 cm in dia and operated at 350 to 700 rpm
