The reduction of particles size is the result of the interaction between steel balls and the material.
Ball grading is the ratio of steel balls with different diameters at a certain filling rate.Based on the analysis above, the effect of crushing of steel balls towards material particles mainly happened in region B, as shown in Figure 1. (1)Before the collision happened, the higher energy steel balls owner, the more material particles ware crushed. (2)Since the crushing of material particles is a kind of fatigue damage, the chance of material particles crushed will become higher if the number of collision increases. (3)The effect of steel balls grinding towards material particles mainly happened in region A, as shown in Fig.1.
The size correlation method of Material particle: which help to gain the ratio of different steel balls by making the percentage of different steel balls equal with the percentage of material particle in different size.

With a breakup of PPS/CF10f > 6.7 MPa load and 2 m/s, exceeding the materials wear resistance and strength.
Therefore, all composite materials show heterogeneities in structure and some macroscopic properties.
Compression is assumed as main stress type expected during operation in a piston compressor on composite piston and packing ring materials.

Introduction Fancy yarn refers to the process in spinning and manufacturing line, using special materials, special equipment, or special technology, processing of the fiber or yarn, and has a special structure and appearance effect of the yarn.
The results of fancy yarns application did not come up to expectations, but mathematically, there are finite supplies of basic raw materials in the country, theoretically, there are very limited resources to provide and guide enterprises and designers.
Thirdly, due to lack of professional designers, and knowledge of equipment, materials and technology and as well as not having compete grasp of the influence many style elements, performance and application have greatly limited the fancy sweater.
Experimental materials：3 materials in different proportion: #1dyed fancy yarn of shorter proportion and equal circulation (4~5cm); #2longer proportion and equal circulation (12~17cm); and #3 a combination of #1 and #2 plus non equidistant dyed fancy yarn (4~5:30~33cm), as shown in table 1.

In addition, SF can induce close packing of materials, reduced bleeding and reduced pore size as well as generate more nucleation sites to accelerate hydration reactions because of its significant quantity of active silica and high specific surface area (typical size of 0.1-0.2 µm) [2].
Experimental Program Materials, Mixture Proportion, and Specimen Preparation.
The materials used for preparation of AC were sand, portland cement, SF, GGBFS, lime, gypsum, aluminum powder, and water.

It is now possible to obtain highly pure materials, resulting from concentrated studies on oxide semiconductors, especially in the 80s.
With these three unique properties, ZnO could be one of the most important materials in future research and applications.

It can be performed with a host of materials, including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.
To the thermoplastic material of the ABS + PC glass fibbers, mainly used in the automotive industry.
Based on company´s materials of HRS (Hot Running Systems), one of the world's leading manufacturers of heated running system, the diameter of the main channel was changed to Ø 8 mm.
By this solution could be achieved non-waste injection, because the material will solidify only in the mould cavity, while the material in sprue is due to the use of heated running system still in a liquid state.
