When
these granular particles are left on a vibrating solid surface, they are not only subject to random vibrations, they are also under the spell of solid friction forces, like the force a dry floor would exert on a brick in contact with that floor.

That is to say, we must assume, on the strength of their common behavior (multiplicity in similarity) that all, in their varied degrees of complexity and magnitude, are manifestations of a single, fundamental,
granular structural principle of the Universe — simply larger or smaller
particles.
Demonstrating Ishida's ability to develop weighers for special applications, the Ishida Cut-Gate weigher for
granular products incorporates a servomotor - powered gate that delivers a gentle but precise opening and closing profile to offer accuracy levels of typically + -4 g for 1 kg target weights while the gentle handling operation mode preserves
particle size and structure.
The first filter removes large sediment
particles, while the second filter uses a
granular activated carbon followed by an even finer carbon filter to prepare the water for the reverse osmosis filter.
«Law of
particle dynamics of
granular gases: Increasing temps in cooling systems.»
This means that the model can also be used in further studies of a driven
particle in a
granular fluid, which is relevant to a number of industries, ranging from construction to pharmaceuticals.
Pöschel explains: «By using a new system of kinetic equations and the relevant scaling methods, we were able to depict the dynamics of
particle aggregations in
granular gases reliably for the first time.
Granular gases are systems that contain macroscopic
particles in low density.
«In isolated
granular gases without external energy input, the kinetic energy of the
particles constantly decreases due to the collisions, which is why the
granular temperature also decreases», explains Prof. Dr. Thorsten Pöschel from the Chair for Multiscale Simulation of Particulate Systems at FAU.
The electric current is therefore a
granular medium, consisting of individual
particles.
Ivo said: «Our findings extend shear jamming beyond dry
granular materials and demonstrate its relevance to dense
particle suspensions too.
But its width varied with the average speed of a
particle — the
granular equivalent of temperature in gases.
