The ingredients of stone materials are very complex, and the main component of sewage caused by them is a mixture of water, abrasive dust, slag grinding grain, marble and granite debris.
When annual working days d is300, daily working time t is 8 hours, the required equipment number is 2 block machine and a polishing line and 2 bridge cutting machine.

In mineral processing process, the vast majority of mineral products contain a large number of moisture[6], the concentrate obtained by gravity concentrate plant and magnetic separation plant also contains a large number of water.
Study on the Classification of Fine Grain Material [J].

Processing is intended to achieve uniform microstructures with fine grains and improved mechanical properties.
Figure 5 a-c shows the microstructure of the base material and the processed material from Exp. 13A with fine and homogeneous grains.
Conclusions · Experimental research for SFSP processing was carried out for EN AW 5754 aluminum alloy of 3 mm thickness under the same conditions regarding the work equipment, the processing tool with conical pin with 4 flat chamfers (Fig. 1b,c), as well as how the liquid working medium is applied to the SFSP processing, the results obtained being influenced by the use of different process parameters and the number of processing passes
· At the microstructural level, fine and homogeneous grains are observed in the processed material, flow lines of the processed material and its mixing zone being visible when processing in multiple passes

Retention is basically mechanized by irreversible attachment to the rock grain surfaces which itself is impacted by a number of factors including surface roughness, heterogeneity in the charge, and colloid variability [36].
While filtration is a process where the attractive interactions between particles and grain surface irreversibly adsorbs other particles onto the grains surface [37].
In a model for irreversible attachment in a one-dimensional homogeneous media with no salinity and a constant attachment coefficient the results gained indicate that grain size and its dispersivity have the highest impact on transport while porosity impact is less.

If then the fracture of several ribs involves a greater number of sectors, a thoracic flap is generated in 30% of cases and mortality rises to 20%.
To overcome these problems, the research has focused on two aspects: a) grain refinement of the material to enhance the mechanical properties [24-26]; b) tailoring of alloy composition and study of LDHs surface coatings to increase corrosion resistance.
To assess the presence of a preferred orientation of the grains, the relative intensities of the diffraction peaks were compared to those of Mg reported in the JCPDS-ICDD database (file 35-821), corresponding to a material with random grain orientation.

Although it appears that the Bi-rich droplets nucleate in a position ahead of the monotectic front, as solidification continues (at t = 3.5 and 7.0 s) it becomes apparent that two α-Al grains have also nucleated and are growing in the same location as the initial L2 nucleation at t = 0.
It would be expected that α-Al grains are also present at t = 0 as homogeneous nucleation of L2 would be highly unlikely when thermodynamically favourable nucleating surfaces, such as α-Al, are present.
At t = 3.5 s, equiaxed grains appear to be growing in the same location as the initial L2 nucleation.
The open equiaxed network allows Bi-rich droplets to settle freely and they accumulate on top of α-Al grains (highlighted by circles at t = 7.0 s) where the network becomes more constricted.
Droplet Motion and Interaction At higher ∇T's, a large number of L2 droplets are set in motion by thermosolutal Marangoni forces.

For example, post-mortem analyses on worn oxide bonded SiC- based tiles have shown that molten salts react with SiC aggregates and matrix of the material and form para-wollastonite around SiC grains and in the porosity, near the hot face of refractory tiles.
The gas O2 react with SiC-grain to form SiO2 layer surrounding the sound part of SiC grain.
The material considered hereafter is a commercial SiC-based refractory, having a particle size distribution ranging from 20 µm to 3 mm and containing approximately 85 wt.% of SiC-grains.
The oxidation extent instead of the SiO2 mass fraction or the SiC content seems to be a better state variable because initially it is null at each point and it reduces the number of variable to compute (one instead of two that, are not independent).

However, from the AFM image of the spin-coated film at 110 ◦C (Fig.3c), the size of crystalline grains of RR-P3HT is larger than that for 50 ◦C(Fig.3b), which shows the opposite tendency to that between 25 and 50 ◦C in association with increase of temperature.
Consequently, density of crystalline nuclei was maximized around 50 ◦C, giving crystalline grains with the smallest size.
Additionally, spin-coating precipitation of RR-P3HT was seemingly delayed by the high temperature solution of 110 ◦C, and this causes to slightly gain the grain size of RR-P3HT.
The morphological changes give the variation of source-drain conductivity of OFETs; namely, the higher conductivity is seen in the larger crystalline grains, particularly in low current region (Fig.2d).
A multiple parallel network[11, 12, 13, 26] is suggested to maintain high performance, which needs a large number of independent noise sources ideally.

In the close-packed cubic structure, the oxygen ion is located at the center of eight little cubics in the unit cell and is said to have a coordination number of 4.
Forming nanocrystals could be attributed to the fast velocity of synthesis reaction and there is not sufficient time for grains to grow completely.

The damage characteristics: stress exceeds the material fatigue limit, after a certain number of cycles, fatigue failure occurs, many pits appear at the surface. 2.1.4 Erosion wear Erosion is one form of wear that fluid containing solid particles impact solid surface, damage the surface.
At the same time, form of broken tooth and arrangement are special designed based on actual requirements, bulk materials are one-time gnawed in, the grain which is smaller than the asked size go directly though the crushing cavity.
