Automatic universal crusherCategory:

1. According to major categories, crushers can be divided into medical crushers and mining crushers. Among them, medical stone crushers are mainly used for stone fragmentation, generally using resonance and other methods to break stones and avoid various risks caused by surgery.

2. According to the principle of crushing, commonly used crushing machines for heavy mining machinery include jaw crushers, impact crushers, vertical impact crushers, hydraulic cone crushers, ring hammer crushers, hammer crushers, roller crushers, composite crushers, cone crushers, two-stage crushers, gyratory crushers, mobile crushers, etc.

3. The working principles of different models of crushers are completely different. Taking the ring hammer crusher as an example:

Hammer crushers mainly rely on impact energy to complete material crushing operations.

When the hammer crusher is in operation, the motor drives the rotor to rotate at high speed, and the material uniformly enters the crusher chamber. The high-speed rotating hammer head impacts, shears and tears the material, causing it to be crushed. At the same time, the gravity of the material itself causes the material to rush from the high-speed rotating hammer head to the baffle and screen strip inside the frame. At the lower part of the rotor, there is a sieve plate, and the particles smaller than the sieve hole size in the crushed material are discharged through the sieve plate. The materials larger than the sieve hole size are retained on the sieve plate and continue to be hit and ground by the hammer.

Automatic universal crusherPerformance Usage:

Although the counterattack crusher appeared relatively late, it has developed rapidly. It has been widely used in various mineral processing and fine crushing operations by industrial sectors such as cement, building materials, coal and chemical, and mineral processing in China It is also used as a coarse crushing equipment for ore. The reason why the impact crusher has developed so rapidly is mainly because it has the following important characteristics.

The product has uniform particle size The phenomenon of over crushing is rare. This kind of fragmentation. It uses kinetic energy to crush ore, and the kinetic energy of each piece of ore is proportional to its quality.

Therefore During the crushing process, large pieces of ore are subjected to significant crushing But smaller particles of ore are not crushed under certain conditions Therefore, the particle size of the crushed product is uniform.

Purchasing tips:

Mine crushers are important equipment in mining, which are divided into hammer crushers, jaw crushers, impact crushers, etc. The performance and price of different mine crushers vary.

Price is a common concern when purchasing mining crushers. Some people believe that high priced mine crushers are good mine crushers, but this statement is not entirely correct.

Mining crushers produce different models of crushers according to their different uses. For example, impact crushers are popular due to their simple structure and high crushing ratio. However, due to the low wear resistance of the impact crusher plate hammer and impact plate, the crushing work of high hardness materials is not smooth; Hammer crushers play a significant role in high hardness crushing due to their hammer heads. Therefore, mine crushers are not necessarily expensive, but rather need to be chosen based on the type of ore they need to mine in order to save time and costs.

Fault repair:

Due to the relatively harsh working conditions of the crusher, it often experiences high torque or vibration during operation, which can cause transmission system failures. Common causes include wear on the bearing chamber and bearing position, wear on the shaft head and keyway, wear on the pulley and coupling inner hole, etc. At the same time, due to the severe dust and poor lubrication conditions on the production site, it can also accelerate the wear of the transmission parts.

In addition, modern production enterprises have a high degree of automation and continuity in production, and the requirements for smooth operation of equipment are also increasing. And crushing equipment is also developing towards large-scale and high-yield quantification, and the difficulty of disassembly, transportation, and maintenance is constantly increasing. Without advanced maintenance methods, once these equipment problems occur, they cannot be quickly and effectively solved in * time, which will inevitably seriously affect the production of enterprises.

The solution to the wear of the bearing position of the hammer crusher: During the operation of the hammer crusher, due to various factors, the bearing position is worn. After the problem occurs, traditional methods such as welding or brushing plating should be used for machining repair. However, the thermal stress generated by welding at high temperatures cannot be completely eliminated, and short shafts are prone to occur during operation, causing major accidents; Electric brush plating is prone to peeling due to the influence of coating thickness, and under the combined action of various forces, it can still cause further wear.

difference:

1) Working principle of counterattack crusher: During operation, the rotor rotates at high speed under the drive of the electric motor. After the material enters, it collides with the plate hammer on the rotor to break it, and then it is counterattacked to the lining plate for further crushing. Finally, it is discharged from the discharge port.

2) Performance characteristics of impact crusher: unique structure, keyless connection, high chromium plate hammer, unique impact lining plate; Hard rock fragmentation, high efficiency and energy saving; The product is in the shape of a cube, with adjustable discharge particle size, simplifying the crushing process.

3) The most commonly used crusher in the production of mineral processing plants or sand and gravel plants is the jaw crusher. Compared with other crushers, this machine has the advantages of low cost and high efficiency.

4) Application range of impact crusher: It can handle various coarse, medium, and fine materials (granite, limestone, concrete, etc.) with a side length not exceeding 500mm and a compressive strength not exceeding 350MPa. It is widely used in industries such as hydropower, highways, artificial sand and gravel, and crushing.
