Powder metallurgy
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powdersPM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs Powder metallurgy is also used to make unique materials impossible to get from melting or ....

Nanoparticle production
Nanoparticles are materials that are confined to the nanoscale in all three dimensions Engineered nanoparticles play an important role in nanotechnology The specific properties of nanoparticles is defined by particle size, chemical composition, crystallinity and shape During production these can be controlled by temperature, pH-value, concentration, chemical composition, surface ....

Gas Production from Hydrate
Even a small fraction of fine particles can have a significant effect on gas production from hydrate-bearing sediments and sediment stability Experiments were conducted to investigate the role of fine particles on gas production using a soil chamber that allows for the application of an effective stress to the sediment This chamber was instrumented to monitor shear-wave velocity, temperature ....

Removing solids from water
Filters cannot handle the volume of solids that can be handled by sedimentation and desanders, but they are the only practical method for separating very fine particles (< 10 μm) By properly choosing the filter element, filters can remove fine solids in the 05- to 50-μm range and are used as a ,...

Granulation
Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular materialIt is applied in several technological processes in the chemical and pharmaceutical industri Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 02 and 40 mm depending on their subsequent use...

Fine Particle
Colloidal processing has been developed for consolidating fine particles to avoid heterogeneous agglomerates by using electrostatic repulsive forces and/or steric stabilization, since they greatly eliminate large pores and reduce the sintering temperature, resulting in a dense and fine ,...

How gravity concentration recovers ultra
There are several problems that fine and ultra-fine particles can cause depending on the process In gold leaching operations they can cause carbon fouling or interfere with Merrill-Crowe Fines are notorious for being difficult to selectively float as well as degrading the selective flotation of coarser particles when they are intermixed...
