The mission of its raw material workshop is to provide raw materials to the sintering production line.
At first the materials are carried by train to the dumper, and then the powered materials are taken into the storage from the dumper.
The materials in the falling process occupy portion of capacity in the mine warehouse.
(2)The airflow volume during the rolling of the train is pertinent to the mass and volume of the materials, the height and velocity of the materials (including the rotary velocity of the container and dumping velocity of the materials), and the surface area of the container

One possible approach for this is the use of different metallic materials in composite construction.

The exponential and power material functions are often applied to functionally gradient materials (FGM).
For homogeneous, isotropic and linear elastic materials, the eigenfunctions are only three ones, i.e.
The rectangular domain consists of base materials (BM), heat-affected zone (HAZ) and welding material (WM).
The fracture remains a key failure mode of these materials.
The higher order terms differ considerably from their counterparts for homogeneous materials.
