1. Mineral resources and resource conditions factors As a national resource, mineral resources must first be determined according to national policies, including overall economic policies, resource development and resource protection policies, and determine the reasonable scale of the project according to the corresponding development plan; It is also necessary to consider the resource conditions such as the geological structure of the minefield, the recoverable mineral resources, the reserves, the stability of the ore layer and the feasibility of the development technology.
2. Market factors The market demand situation of project products is the prerequisite for determining the scale of project production. Under normal circumstances, the production scale of the project should be limited to the market demand, and adjusted according to the long-term development trend of the project product market. The mineral market has a lot to do with the economic situation of the country as a whole and national policies.
3. Technical factors Advanced production technology and technical equipment are the basis for the survival of the scale of the project, and the corresponding management technology level is the guarantee of achieving economies of scale. Of course, advanced technology and high-level management require high investment, so the investment in technology level is always linked to economies of scale.
4. Environmental factors Environmental factors are policy factors, fuel and power supply, cooperation and Conditions disabilities, transportation and communication conditions which policy factors, including industrial policy, technology funding policy, financial policy, regional and industry economic development planning It has a greater impact on the construction of investment mines.
(II) Determination of the construction standard level The main contents of the construction standard are: construction scale, floor space, process equipment, building standards, supporting projects, labor quotas and other aspects of standards or indicators. The construction standard is an important basis for compiling, evaluating and approving the feasibility study of the project. It is an objective measure to measure whether the project cost is reasonable and the construction of the supervision and inspection project.
The standard of construction should be determined from the current level of economic development in China, and it should be determined reasonably by distinguishing different regions, different scales, different grades and different functions.
(III) Choice of construction site The project site of mine construction is first determined by the capitalization conditions; the location selection of the project construction is also restricted by various factors such as construction conditions, product sales and other social, political, economic and national defense. At the same time, the choice of construction site also directly affects the construction conditions of the project. The construction site of the mine project is even related to the urban and rural construction planning and development of the development site.
(IV) Determination of engineering technology plan The determination of engineering technology plan mainly includes the determination of production process plan and the selection of main equipment.
There are two main criteria for determining the production process plan: advanced application and economic rationality.
The selection of major equipment should pay attention to the advanced nature. Special consideration should also be given to supporting problems, and attention should be paid to the matching problems between imported equipment and domestic raw materials, equipment, maintenance parts and maintenance capabilities.
Plastic Injection Control Handle
The handle is a kind of mechanical accessory, which is convenient for workers to operate machinery. Mechanical accessories industry handles have two main types of materials are plastic, steel parts. Steel parts are machined by machine and differentiated from castings. The plastic handle is divided into thermoset plastic and thermoplastic plastic.
According to handle material is divided into: bakelite handle, iron handle, zinc alloy handle, steel handle and so on.
According to the working performance of the handle, it can be divided into: handle, turning handle, locking handle, adjustable handle, folding handle, handle sleeve, handle lever, handle seat, swinging handle, three-ball handle, etc.
According to the handle shape can be divided into: handle, straight handle, turn the handle of surface, turn the handle of the little turn the handle, the steel chrome plated handle, handle the seventh, peulthai the (adjustable set handle), folding handle, long handle, the handle cover, oval handle cover, handle the ball, rod, joystick, disc handle, lock handle, positioning controller, three goals, positioning joystick, ball head, oblique cone column joystick, etc.
