Generally speaking, mine equipment mainly includes five processes: feeding, crushing, sand making, screening and sand washing. The equipment required for these five modules is as follows:
1, feeding equipment
Vibrating feeder: also known as feeder, it is generally used in the front stage of primary crushing equipment, and is used to quantitatively, uniformly and continuously send granular and blocky materials from the storage bin to the receiving device in the production process.
2. Crushing equipment
(1) Jaw crusher: generally used for primary crushing of various materials, used as coarse crusher and medium crusher in mining, infrastructure, building materials and other departments, with small occupation space and large crushing ratio.
(2) Cone impact crusher: Cone crusher and impact crusher are suitable for medium crushing and fine crushing of various rocks and minerals, mainly used for secondary crushing in sand production line. Cone crusher is mainly used for finely crushing high-hardness stones, and the machine is wear-resistant and durable, with long service life; Impact crusher is mainly used for finely crushing soft rocks, and can be used for processing small stones and coarse sand products.
3. Sand making equipment
Sand making machine: Sand making machine is the core equipment of the whole sand and gravel production line, which is suitable for the crushing and molding of materials. Generally used for three-stage crushing of stone production line, the principle of "striking iron with stone" and "striking stone with stone" is adopted to achieve good molding effect.
4. Screening equipment
Responsible for screening gravel with different particle sizes to form different gravel products and improve production efficiency.
5. Sand washing equipment
Sand washer is an important equipment for sand washing, which can effectively remove the soil and stone powder covered on the sand surface, improve the quality of sand, and thus meet the needs of users for materials. At the same time, it also has the function of recovering tailings, with high cleanliness, environmental protection and energy saving.
Second, the development prospect of mining machinery and equipment
As we all know, no matter what kind of mining machinery and equipment, the market or development in these two years is far worse than before, which may be the reason why everyone is extremely worried about the future development of mining machinery and equipment. In fact, despite other complicated factors, the development of mining machinery and equipment in the future can still be expected. Mining machinery is also developing in the following directions:
1, large scale
China has entered the ranks of big countries in mining machinery production, consumption and import, but it is big but not strong. Based on the present situation of mining machinery industry, mining machinery enterprises in China should further deepen the reform, actively adjust the industry and product structure, change the mode of economic growth, enhance the ability of independent innovation, speed up the research and development and market development of high-end mining machinery, mineral processing equipment, crushing equipment and key parts, further improve product quality and service awareness, improve the comprehensive competitiveness of the whole industry, adhere to the road of green innovation, achieve sound, rapid and sustainable development, and complete the goal of changing from large to strong.
2. Digitization Digitization Digitization Digitization
With the progress of computer technology, the development of unmanned mining technology has been promoted, from automatic mining or remote mining of traditional mining technology to intelligent mining, digital communication and other unmanned mines. Digitalization paints a new prospect for mines, excavates and integrates the information resources of enterprises, realizes the industrial process reengineering of open-pit mining, and completes the construction and integration of subsystems such as geological environment modeling, production planning and execution, production scheduling, product quality monitoring, equipment condition diagnosis, personnel deployment, logistics, capital flow and engineering disaster warning, local environmental monitoring, expert evaluation and decision-making under special working conditions, making the whole enterprise a complete and smooth management system.
3, intelligent
Automatic unmanned face mining is the development direction of underground or dangerous environment mining, and it is also an effective way to ensure the safe mining of the face. Comprehensive use of mining science, automation technology, communication technology, computer science and technology. , carry out basic theoretical research, develop new technologies and equipment for automatic unmanned coal mining face, and make mining machinery develop in the direction of robot and intelligence. The structural health of mining machinery directly affects mine production and the safety of miners' lives. The self-detection and self-diagnosis system of mining machinery structure adopts an intelligent structure that integrates sensors, controllers and actuators, and endows the structure with some intelligent functions and life features such as health self-diagnosis, environmental self-adaptation and damage self-repair, so as to achieve the purpose of enhancing structural safety, reducing mass, reducing energy consumption and improving performance, which is the direction of online monitoring of major mining machinery products in the future.
4. Ecology
Mining machinery is a big consumer of resources and a source of pollution. To realize the harmonious development facing the natural environment, it requires the mining machinery to be "ecological", and constantly innovate the manufacturing mode, manufacturing resources and manufacturing process organization with the help of various advanced technologies, so that the products will not produce or minimize environmental pollution during the whole life cycle, with the highest resource utilization rate and the lowest energy consumption, and finally realize the coordination of economic and social benefits of enterprises. Efficient and pollution-free fuel cell mining machinery has a good development prospect.
5. Internationalization
The product development of global product development enterprises in machinery manufacturing industry is not behind closed doors, but oriented to open public platforms and social resources. The demand of economic construction has also promoted the development of mining machinery. Mining machinery manufacturing industry has experienced the development path of introducing, digesting and absorbing foreign advanced technology, cooperating in design and manufacturing, and independently designing. At the same time, there is a certain distance from the level of developed countries in the original development and engineering of new industries, new equipment and new technologies.
In fact, from the above five development trends, we don't need to worry about the future of mining machinery and equipment. Even if the external economic development goes down, I believe that the development of mining machinery and equipment can still be expected.
