Mining equipment manufacturing refers to the manufacturing and sales of various equipment required for production mining, stone processing, mine construction and other related fields. It can be seen that mining equipment manufacturing belongs to the heavy industry and construction machinery manufacturing industries.
Mining machinery is machinery directly used in operations such as mineral mining and enrichment. Including mining machinery and mineral processing machinery.
The working principles and structures of prospecting machinery are mostly the same or similar to mining machinery used to mine similar minerals. Broadly speaking, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mining operations.
Crushing equipment is a mechanical equipment used to crush minerals. Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles.
Commonly used sand and gravel equipment include jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, and roller crusher. machine, double-roller crusher, two-in-one crusher, one-time forming crusher, etc.
Mining machinery is machinery and equipment used for direct mining of useful minerals and mining operations, including: mining machinery for mining metallic ores and non-metallic ores, coal mining machinery for coal mining, and oil drilling machinery for petroleum mining.
Extracting machinery Extracting machinery used for underground and open-pit mining includes: drilling machinery for drilling blast holes, excavation machinery and loading and unloading machinery for excavating ore rock, and excavation machinery for drilling ceilings, shafts and leveling tunnels.
Drilling machinery is divided into two categories: rock drills and drilling rigs. Drilling rigs are divided into open-pit drilling rigs and underground drilling rigs.
It is a tunnel-forming or well-forming mechanical equipment that directly breaks the ore rock by utilizing the axial pressure and rotational force of the cutter to roll the rock surface. The tools used include disc hobs, wedge hobs, ball hobs and milling cutters. According to the different excavation tunnels, they are divided into raise drilling rigs, shaft drilling rigs and flat tunnel boring machines.
Coal mining operations have developed from semi-mechanized in the 1950s to comprehensive mechanized in the 1980s. Comprehensive mechanized coal mining widely uses equipment such as shallow-cut double (single) drum combined shearers (or plows), bendable scraper conveyors, and hydraulic self-moving brackets to improve the crushing and loading of coal on the mining face. Coal, transportation, support and other links have been fully mechanized.
Onshore oil drilling and production machinery is divided into drilling machinery, oil production machinery, workover machinery and fracturing and acidification machinery to maintain high production of oil wells according to the mining process. Drilling machinery is a complete set of mechanical equipment used to drill or drill production wells for the development of oil or natural gas.
Mineral beneficiation is the process of selecting useful minerals from the collected mineral raw materials based on the differences in physical properties, physicochemical properties and chemical properties of various minerals. The implementation of this process is called mineral processing machinery. Mineral processing machinery is divided into crushing, grinding, screening, sorting (sorting) and dehydration machinery according to the mineral processing process.
The special dryer for coal slime is a new type of special drying equipment developed on the basis of the drum dryer.
Mining equipment manufacturing belongs to the heavy industry and engineering machinery manufacturing industries. For the processing and manufacturing of this type of mechanical equipment, we need to use large CNC press brake machines, plate shearing machines and plate rolling machines. The plates used in the manufacturing of large equipment are relatively large and thick. Manufacturers need to customize large press brake machines and plate rolling machines according to the plates to process the shells or components of mining equipment.
- Turning
- Milling
- CNC machine tool processing (cutting, bending, rounding, etc.)
- Planing
- Grinding
Let's follow the editor to understand the production process of grinding equipment from five aspects: batching, welding, machining, assembly, and spraying.
Commonly used processing equipment: plasma cutting machine, flame cutting machine, sawing machine
Advanced equipment in the industry: ultra-high-precision batching equipment—laser cutting machine, CNC shearing machine
First of all, we need to understand what the standards for welding process inspection are. Mainly include: welding nodules, undercuts, incomplete welding, slag inclusions, cracks, and pores.
Commonly used processing equipment: handheld arc welding, carbon dioxide gas shielded welding, vibration effectiveness meter
Welding defect inspection instruments: ultrasonic flaw detector - internal defects, magnetic particle flaw detector - surface flaw detection
Sheet metal equipment such as bending/rounding/stamping: high-precision punching equipment, 400T-800T large-tonnage bending machines (CNC bending machines are large-scale high-precision bending equipment in the industry)
Show Case:
CNC Press Brake For Mining Equipment Industry 300T/3200
Commonly used processing equipment: horizontal lathes, vertical lathes, boring and milling machines, planers, grinders
Industry-leading equipment: Fully CNC double-column vertical lathe
Hydraulic/cold loading/hot loading process equipment: fully automatic hydraulic bearing press, industrial freezer, constant temperature oil bath heater
Advanced equipment: bridge-type test machine platform, semi-automatic assembly production line
After the processing of each component of the equipment is completed, it needs to enter the spray booth for spray painting. There are also technical differences in this link. The process standards of engineering vehicles are adopted to ensure the appearance of the equipment while preventing rust and corrosion on the surface of the equipment.
In the overall manufacturing process of mining machinery, it is not only necessary to apply traditional mechanical equipment system engineering manufacturing technology. It also needs to be combined with modern advanced computer communication technology, sensor technology, fully automated technology and new material production technology to ensure that the produced mining machinery can be integrated into the entire system from early product design and manufacturing to later product sales and after-sales service. Have strong competitiveness.
With the continuous development of Internet technology, all walks of life are accelerating transformation and upgrading. Traditional industries such as oil, natural gas, and coal mining are no exception. In the context of vigorously promoting safe production in coal mines, major enterprises have also increased their investment and research and development of mining equipment, and promoted the upgrading of mining equipment.
In the future, the mining equipment manufacturing industry will take intelligence, digitization, and automation as its main development directions, pay more attention to the safety, intelligence, efficiency, and refinement of equipment, and achieve green, environmentally friendly, and sustainable development.
Although the mining equipment manufacturing industry occupies an important position in the market, it still faces many challenges. First of all, global market competition is becoming increasingly fierce, and companies need to make great efforts in product quality, branding and technological innovation in order to face competition from around the world.
Secondly, the rapid development of technology and market changes require enterprises to continuously improve their technical level and market adaptability. Finally, mining equipment manufacturing companies need to adapt to changes in domestic and foreign environmental protection policies and improve the environmental protection and green production levels of their products so that companies can truly exert their economic and social benefits.
