Once upon a time, China’s mining equipment development was very backward, and it could not meet the needs of mining. The foreign advanced technology and equipment have blocked us. Chairman Mao said: Block it! Block it for ten years and eight years, all problems in China have been solved! Mao Zedong did not imitate the Soviet post-mechanization, post-collectivization experience . On the contrary, he found the road of “cooperation first, then mechanizationâ€. The older generation of scientific research workers based on the Soviet-style machine imitation, worked hard and accumulated valuable experience for the research and development of mine equipment in China.
On January 17, 1992, a train departed from Beijing and headed for the south. An 88-year-old man was sitting on the train.
He is Deng Xiaoping, the chief architect of China's reform and opening up. He wants to use up the last heat of his life to cheer for the reform.
Suddenly, the spring breeze came, Deng Xiaoping’s southern tour set the tone for reform, and China, especially the southern Pearl River Delta region, has embarked on a path of rapid development. Mining equipment has also entered a new stage of development with the development of the economy. Especially in the 10 years after 2005, China's mining industry has been full of red, and various data have been continuously refreshed, including higher sand and gravel crushing equipment. Requirements.
Today, the small powder will organize the dynamic diagram of the working principle of the crusher in the sand and gravel production line, clearly and intuitively show its working principle! These devices are basically produced in China, and the gap with foreign countries is getting smaller and smaller. The gif is intuitive and concise, and you can understand it without learning mechanics!
The jaw crusher is commonly known as smashed, also known as the tiger's mouth. The crushing chamber is composed of two jaws, which are composed of two jaws, which simulate the two movements of the animal to complete the crushing operation of the material crushing operation. It is widely used in the crushing of various ores and bulk materials in industries such as mining, building materials, roads, railways, water conservancy and chemical industry. The highest compressive strength of the crushed material is 320 MPa.
Impact crusher working principle
The impact crusher is named according to the working principle, that is, the material is crushed by the principle of counter-crushing. It is a crusher equipment which is more fine than the jaw crusher. It is mainly used for fine crushing operations in the stone production line. The crusher cooperates to break.
Working principle of cone crusher
The cone crusher has large crushing ratio, high efficiency, low energy consumption and uniform product size. It is suitable for medium and fine crushed ores and rocks. During the working process of the cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone rotates under the eccentric bushing. The section of the moving cone close to the static cone becomes the crushing cavity, and the material is subjected to the moving cone and The static cone is crushed by multiple extrusions and impacts. When the moving cone leaves the section, the material that has been broken to the required particle size falls under its own gravity and is discharged from the bottom of the cone.
The impact crusher is composed of a motor, a reducer, a rotating shaft, and a striking member fixed to the rotating shaft and a cylindrical body of elastic material. When rotating, the rotating shaft drives the striking member to strike the material to achieve the purpose of crushing. The viscous material is crushed on the cylinder, and the material is not easily adhered to the wall due to the elasticity of the cylinder wall. When used for a long time, when there is adhesion on the wall, the outer wall is struck, and the material is shaken down, thereby solving the problem of crushing of the viscous material.
The hammer crusher is a kind of equipment for crushing materials in the form of impact, which is divided into two types: single rotor and double rotor. It is a section of crushing crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less. Hammer crusher is suitable for crushing medium-hard materials such as limestone, slag, coke, coal and other materials in cement, chemical, electric power, metallurgical and other industrial sectors.
The mobile crushing station has the characteristics of reasonable matching of crushing equipment at all levels, smooth discharge of the whole line process, reliable operation, convenient operation, high efficiency and energy saving. In particular, it has good maneuverability and can be extended along with the raw materials or construction site, and can be combined in various combinations to meet the needs of different materials.

Shaker working principle
The vibrating screen works by reciprocating rotary vibration generated by vibrator excitation. The upper rotating weight of the vibrator causes the plane to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a cone-shaped rotating vibration, and the combined effect causes the screen surface to produce a compound-rotating vibration.
For the roller crusher, a mining machine, also known as a double roll crusher. Mainly used to break ore. The machine has the advantages of small volume, large crushing ratio (5-8), low noise, simple structure and convenient maintenance. It has uniform particle size, low crushing rate, convenient maintenance, sensitive overload protection, safety and reliability. Applicable to coal, metallurgy, mining, chemical, building materials and other industries.
Double-light roll crusher can be used for fine ore and rock of high and medium hardness in industrial sectors such as mineral processing, chemical, cement, refractory materials, abrasives and building materials, especially in the construction materials industry. The product has more excellent effects than the general crushing machine.
