Particle Analysis in Mining and Minerals - HORIBA

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

Methods for Separating Mixtures | Chemistry for Non-Majors

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.

Which Grinding Wheel Should I Choose? | Norton

Nov 21, 2018· A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.

Ultimate Materials Guide - Tips for 3D Printing with ABS

ABS is known for its toughness and impact resistance, allowing you to print durable parts that will hold up to extra usage and wear. LEGO building blocks are made from this material for that same reason! ABS also has a higher glass transition temperature, which means the material can withstand much higher temperatures before it begins to deform.
