Mechanical engineering（ore beneficiation） is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines.
Mechanical engineering emerged as a field during the industrial revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics. The field has continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as composites, mechatronics, and nanotechnology. Mechanical engineering overlaps with aerospace engineering, marine engineering, building services engineering, civil engineering, electrical engineering, petroleum engineering, and chemical engineering to varying amounts.
Then, let's talk about some methods to save materials.
First, adopt advanced anti-corrosion technology, extend service life of equipment.
Corrosion does harm to people. On the one hand, it causes direct loss of equipment, spare parts and other materials, on the other hand, affects the normal production, deteriorates the operating environment, and affects product quality as well as significant loss of personal safety.
Second, adopt advanced technology, increase utilization rate. Adopt advanced manufacturing technology to improve casting accuracy, promote precision forming technology and expand the proportion of forgings in the production of metal parts; Adopt material surface treatment technology to improve material surface properties, arrive low energy and materials consumption; For critical infrastructure, such as bearings, gears, springs, hydraulic and pneumatic components and mold, expand the use of refined steel, deoxidized steel and effective heat treatment to significantly extend its life.
Finally, promote the research and application of remanufacturing engineering.
Remanufacturing engineering technology can not only restore the original product's technical performance, and timely introduce new technologies, new processes and new materials, improve product performance and reliability, thus extending the life of the product. The cost of re-manufactured products is only 40% -60% of the new products, can achieve the purpose of turning waste into treasure, open up a new way to reduce material consumption and save raw materials.
As the modern manufacturing industry aggravates the influence on economic development and industrial structure, a new round economic structure adjustment will be inevitable; Hongxing machine always grasp the situation, optimize the industrial structure, focus on the integration of new technologies, innovate crusher equipment to cast world-level brand, stimulate the industry self-reform and boost mining machinery industry entering into international market.
