Crushing equipment
Crushing equipment is the mechanical equipment used to crush minerals.
Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging materials. The commonly used sand and stone equipment is jaw crusher, impact crusher, impact crusher, compound crusher, single section hammer crusher, vertical crusher, rotary crusher, cone crusher, roll crusher, double roll crusher, two in one crusher, a forming crusher and so on.
According to the crushing mode, mechanical structure characteristics (principle of action) to be divided into six categories.
(1) jaw crusher (tiger mouth). The crushing action is to press the movable jaw periodically to the fixed jaw and crush the ore block clamped in it.
(2) cone crusher. The ore block is located between the inner and outer cones, the outer cone is fixed, and the inner cone makes eccentric oscillation to crush or break the ore block clamped in it.
(3) roll crusher. In the intercalation of two rotating circular rollers, the ore blocks are mainly subjected to continuous crushing action, but also with grinding and stripping action, and the toothed roller surface is also cracked.
(4) impact crusher. The ore block is crushed by the impact of moving parts with rapid rotation. Belonging to this category can be divided into: hammer crushing machine; Cage crusher; Impact crusher.
(5) grinding machine. The ore is crushed by the impact and abrasion of a grinding medium (ball, bar, gravel, or block) in a rotating cylinder.
(6) other types of crushing and grinding machines.
Mining machinery
Mining machinery is the mechanical equipment used for the direct mining of useful minerals and their preparation, including: mining machinery for the mining of metallic ores and non-metallic ores; Coal mining machinery for coal mining; Oil drilling and production machinery for the production of petroleum. The first typhoon moving disc shearer was designed by British engineer walker and was successfully manufactured around 1868. In the 1880s, hundreds of Wells in the United States were drilled with steam-powered percussion drills. In 1907, a rotary drill was used to drill Wells and gas Wells.
Mining machinery
The mining machinery used for underground and open pit mining includes: drilling machinery for gun holes; Excavating machinery and loading and unloading machinery for mining and loading rocks; A tunneling machine for drilling patios, shafts, and drift.
Drilling machinery
Drilling machinery is divided into two categories: rock drill and drilling machine. Drilling machine is divided into open air drilling machine and underground drilling machine.
(1) drill: used for drilling in the hard rock above the diameter of 20 ~ 100 mm, depth within 20 meters of the hole. According to its different power can be divided into pneumatic, internal combustion, hydraulic and electric drill, among which pneumatic drill is the most widely used.
(2) open air drilling machine: according to the different working mechanism of broken rock, it is divided into steel rope impact drilling machine, subsurface drilling machine, cone drilling machine and rotary drilling machine. Because of its low efficiency, the steel rope percussion drill has been gradually replaced by other drills.
(3) downhole drilling machine: drilling hole diameter less than 150 mm downhole gun hole, in addition to the application of the rock drill can also be used 80 ~ 150 mm small diameter subsurface drilling.
Excavating machinery
By means of the rolling action of axial pressure and rotary force of cutter on rock surface, the mechanical equipment of roadway formation or well formation of ore and rock can be directly broken. The cutter is provided with disk hob, wedge tooth hob, ball tooth hob and milling cutter. According to the different tunneling roadway, it is divided into patio drilling machine, vertical drilling machine and roadway drilling machine.
(1) patio drilling rig, specially used for drilling patio and sliding well, generally do not need to enter the patio operation, with the cone bit drilling guide hole, with disk hob composed of reamer upward reaming.
(2) vertical drilling machine is specially used for drilling into a well, by the drilling tool system, rotary device, derrick, drilling tool lifting system and mud circulation system.

Coal mining operations have developed from semi-mechanization in the 1950s to comprehensive mechanization in the 1980s. Comprehensive mechanization of coal mining is widely used in shallow cut deep double (single) drum combined shearer (or planer), flexible scraper conveyor and hydraulic self-shifting support equipment, so as to achieve comprehensive mechanization of coal mining face crushing, loading, transportation, support and other links. Double drum shearer is a coal falling machine. Motor cutting part of the reducer to transfer power to the screw drum coal, the movement of the machine by motor traction part of the transmission device to achieve. Traction mode basically has two kinds, namely cable traction and no cable traction. The anchor chain traction is realized by meshing the chain wheel of the traction part with the anchor chain fixed on the transport machine.
Oil drilling
Onshore oil drilling and production machinery. According to the production process, it is divided into drilling machinery, oil production machinery, workover machinery and fracturing and acidizing machinery to maintain high production of oil Wells. A complete set of mechanical equipment for drilling or drilling production Wells for the development of oil or gas. Oil drilling machines, including derrick, winch, power machine, mud circulation system, pulley system, turntable, wellhead device and electrical control system. Derricks are used for hoisting other heavy objects up and down the drilling platform and hoisting the drilling tools in the well for drilling.
Mineral processing machinery
Mineral processing is the process of selecting useful minerals from the collected mineral raw materials according to the physical properties, physical chemical properties and chemical properties of various minerals. Those who carry out this process are called dressing machines. Mineral processing machinery according to the mineral processing process is divided into crushing, grinding, screening, sorting (separation) and dehydration machinery. Crushing machinery commonly used jaw crusher, rotary crusher, cone crusher, roll crusher and impact crusher. The most widely used grinding machinery is the cylindrical mill, including bar mill, ball mill, gravel mill and superfine laminated self-grinding machine. Inertia vibrating screen and resonance screen are commonly used in screening machinery. Hydraulic classifier and mechanical classifier are widely used in wet classifier. Separation and flotation machinery commonly used in the full section of the air-lift micro-bubble flotation machine, dehydration machinery is more famous for the multi-frequency dehydration screen tailings dry drainage system. One of the most famous grinding systems is the superfine laminated self-grinding machine.
Drying machine
Coal slime special dryer is a new special drying equipment developed on the basis of drum dryer, which can be widely used in:
1. Drying of coal slime, raw coal, flotation cleaned coal, mixed cleaned coal and other materials in the coal industry;
2. Drying of blast furnace slag, clay, bentonite, limestone, sand, quartz stone and other materials in the construction industry;
