【Mechanical cax360 No. 314】There are many types of mining machinery, and different machinery has different working principles. So how does this huge mining equipment work? Today Xiaobian sorted out the dynamic diagram of the working principle of some mining machinery, with these intuitive mechanical GIFs, Xiaobai can also understand in seconds.
▲Jaw crusher
The jaw crusher is mainly used for medium-grain crushing of various ores and bulk materials, and the maximum compressive strength of the crushed material is 320mpa. The performance characteristics are large crushing ratio, uniform product particle size, simple structure, reliable performance, simple maintenance, and low operating costs.
The working principle of the jaw crusher: the jaw is suspended on the mandrel and can be swung left and right. When the eccentric axis rotates, the connecting rod does up and down reciprocating movements, driving the two thrust plates to do reciprocating movements, thereby pushing the jaws to do left and right reciprocating movements to achieve crushing and unloading.
▲Impact crusher
The impact crusher is mainly used for metallurgy, chemical industry, building materials, hydropower and other material processing that often needs to be relocated, especially for the operation of mobile stone materials such as highways, railways, hydropower projects, etc., and can adopt a variety of configuration forms according to the type of processing raw materials, scale and requirements of finished materials.
▲Cone crusher
When the cone crusher is working, the rotation of the motor is rotated through the pulley or coupling, the drive shaft of the cone crusher and the cone crusher under the compulsion of the eccentric sleeve around the fixed point for a pendulum movement. So that the crushing wall of the crushing cone is sometimes close to and sometimes away from the surface of the rolling mortar wall fixed on the adjustment sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing chamber to achieve the crushing of the ore.
The motor drives the eccentric sleeve through the bevel gear to rotate, so that the crushing cone makes a pendulum movement. The crushing cone is sometimes close to and sometimes away from the fixed cone to complete the crushing and discharging.
▲Impact crusher
The working principle of the impact crusher is simply the principle of stone hitting stone. Let the stones collide with the stones thrown out by the impeller acceleration during the natural falling process, so as to achieve the purpose of breaking! When the accelerated stones collide with the naturally falling stones, a vortex is formed, and the two times of crushing are carried out during the return process, so the wear and tear on the machine's counterattack plate during operation is very small.
▲Hammer crusher
The hammer crusher is composed of the hammer crusher box, rotor, hammer head, impact liner, screen plate and so on. The hammer crusher is a crusher for direct crushing of materials with a maximum particle size of 600-1800 mm to 25 or 25 mm or less. Hammer crusher is suitable for crushing medium hardness materials in cement, chemical, electric power, metallurgy and other industrial sectors, such as limestone, slag, coke, coal and other materials in the medium crushing and fine crushing operations.
▲Washing machine
The washing cylinder of the washing machine is supported by four tug wheels, the motor drives the reducer, and the large and small gears drive the cleaning cylinder to rotate at low speed. The aggregate containing mud mass and stone powder is fed from the inlet, enters the rotating drum, and the wear-resistant rubber liner with a certain angle installed in the cleaning drum is continuously thrown up and down, and it is circulated many times during the movement from the feed end to the discharge end, and is washed by the flushing water in the forward or reverse direction, and the clean aggregate is discharged after being screened and dehydrated by the discharge end tube. Wastewater containing sludge flows out through a perforated baffle at the outlet or feed end.
▲Wet dust collector
Wet dust collector usually refers to the dust removal equipment containing dust flue gas through contact with water, lye and other liquids to achieve the purpose of removing dust particles. It is characterized in that: comprising a dust collection chamber, in the lower part of the dust collection chamber in the direction of the circumferential tangent direction is provided with an intake channel, at the top of the dust collection chamber is connected to the discharge hood, in the intake channel near one end of the dust collection chamber is provided with a spray water atomization device, the middle and upper part of the dust collection chamber are provided with a first stage rotary leaf group and a second stage rotary leaf group.
▲Cyclone dust collector
The dust collection mechanism of the cyclone dust collector is to make the dust-containing gas flow rotate, separate the dust particles from the air flow and trap them on the wall with the help of centrifugal force, and then use gravity to make the dust particles fall into the ash bucket.
▲Double roller crusher
The double-roll crusher uses two sets of separately driven rollers, and the extrusion and grinding shear forces generated by relative rotation to crush the material. When the material enters the crushing chamber of the machine, the material is subjected to the meshing action of the rotating roller, so that the material is forced through the two rollers, while being squeezed and sheared by the roller, the material begins to break, and the small particles after fragmentation follow the tangent line of the roller rotation, through the gap between the two roller shafts, thrown under the machine, and the large particle material that exceeds the gap continues to be broken into small particles discharged.
▲Ball mill
Ball mill is composed of horizontal cylinder, inlet and outlet hollow shaft and grinding head and other parts, when the ball mill barrel rotates, the grinding body due to inertia and centrifugal force, the role of friction, so that it is attached to the cylinder liner plate is taken away by the cylinder, when it is brought to a certain height, due to its own gravity action and is thrown down, the falling grinding body is like a projectile body to crush the material in the cylinder.
▲Linear vibrating screen
Linear vibrating screen is the use of inertial exciter to produce vibration, linear vibrating screen vibration source has a motor to drive the exciter, the exciter has two shafts, each axis has an eccentric weight, and rotated in the opposite direction, so also known as a biaxial linear vibrating screen, by the two gear mesh to ensure synchronization. When two discs with eccentric weights are rotated, the centrifugal force f generated by the two eccentric weights cancels each other out on the x-axis, and the components in the y-axis are added together, and the result is a reciprocating excitation force in the y-axis direction, so that the sieve box produces a reciprocating linear trajectory vibration in the y-axis direction.
▲Round vibrating screen
Circular vibrating screen Circular vibrating screen for circular motion, is a multi-layer, efficient new vibrating screen. Circular vibrating screen adopts cylinder eccentric shaft exciter and offset block to adjust the amplitude, the material sieving line is long, the screening specifications are many, and it has the characteristics of reliable structure, strong excitation force, high screening efficiency, low vibration noise, strong and durable, convenient maintenance, and safety of use.
▲Multi-layer vibrating screen
▲Magnetic separator
Magnetic separator is used for the separation of substances with magnetic differences, suitable for the wet or dry magnetic separation of manganese ore, magnetite, pyrite, roasted ore, ilmenite, hematite and other materials with a particle size of less than 50mm, and is also used for iron removal operations of non-metallic ore, building materials and other materials.
