The other is the aggregate particles of all levels mixture along the direction of the separating materials, at the same time, the relative motion was occurred between the materials.
This will make the materials roll at all directions, resulting in the aggregate segregation, this flow was called turbulent.
From the equation of helix angle , it is known that, the helix angle is determined by pitch and the distancewhich materials to the axis.
In order to improve the transmission efficiency and to ensure the quality of input materials, we should not adopt the screw which pitch is too large.
Therefore, the different position of the spiral should have a different capacity for the delivery of materials.

In the machining process, because the machine works in high speed, materials has harder strength and cutting temperature is higher, so the machine must have some good characteristics, such as good rigidity, large power.
Therefore, study the machining process should accord to the characteristics of the tool and hard materials.
At the same time because small coefficient of thermal conductivity of titanium alloy, cutting to the high temperature, so the material is typical of hard-cutting materials.

Introduction Access to good engineering construction materials is a basic requirement for sound engineering works [1].
The test is only suitable for materials with a maximum particle size of no more than 200 mm due to the plunger.
The outcomes provide a clear understanding of the soil’s characteristics and its performance potential in various engineering applications such as subgrade, sub-base, and foundation materials.

Besides the study on strength properties and mechanism of the reinforced soil (Haeri et al. 2000, Michalowski 2004), the influence of the kinds of reinforcement materials and reinforcing styles on strength has been investigated.

In both cases, total volume of the material was held constant.
Otherwise, the elasticity modules of materials have to be taken into account and the formula has to be transformed into γi=(Est·Ist,i)/(Esk·Ist,i).
Material used in calculations data is presented in table 1.
