As the name suggests, the impact crusher uses the counter force to achieve the crushing effect. After the bulk material enters the crushing chamber between the counterplate and the rotor, the kinetic energy is obtained by the rotation of the rotor part, and it is repeated between the counterplate and the rotor. The impact is successively crushed by the first-stage counter-attack chamber, the second-stage counter-attack chamber and the bottom grinding chamber to achieve the required discharge granularity.

Second, the technical advantage of the impact crusher compared to the hammer crusher

1. It can effectively treat materials with large moisture content and prevent clogging of crusher

When the moisture content of the treated material is too large, the feed chute and the counterplate of the impact crusher may be equipped with a heating device to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom sieve plate to prevent clogging. The hammer crusher cannot be heated to prevent the material from sticking, and the bottom sieve plate must be provided to increase the possibility of blockage.

2. Counter crusher is suitable for both soft materials and very hard materials.

The hammer of the impact crusher is fixed to the rotor by a mechanical clamping structure, and has a large moment of inertia when it rotates with the rotor. Compared with the hammer crusher (the hammer is in a suspended state), the rotor of the impact crusher has greater momentum, adapts to crushing harder materials, and consumes less energy.

3. It is convenient and flexible to adjust the discharge granularity and wide adjustment range.

The impact crusher can adjust the discharge particle size in a variety of ways, such as adjusting the rotor speed, adjusting the backlash and the clearance of the grinding chamber. The gap adjustment can be adjusted mechanically or hydraulically, and the hydraulic adjustment system can be used to easily adjust the gap through the local operation button or the travel control system. The hammer crusher can adjust the discharge particle size only by replacing the bottom sieve plate.

4. The wearing parts wear is smaller than the hammer crusher, high metal utilization

The wear of the counter crusher plate hammer is only present on the side facing the material. When the rotor speed is normal, the feed will fall to the surface of the hammer (the striking surface), and the back and sides of the hammer will not be worn. Even the wear on the side of the material is scarce. And the bottom grinding rod is also easy to replace. The metal utilization rate of the impact crusher plate hammer can be as high as 45% - 48%. The hammer crusher hammer is in a suspended state, and the wear occurs on the upper, the front, the rear and the side. Compared with the hammer, the hammer wear is more serious, and the metal utilization rate of the hammer is only about 25%. Moreover, the rotor body itself may also be subject to wear. The bottom sieve plate of the hammer crusher is seriously affected by the wear, the barrier is completely replaced, and the work of replacing the sieve plate is also complicated.

5. Easy replacement of spare parts and corresponding reduction of maintenance costs

Only 6 hammers are installed on the rotor of the impact crusher. It is convenient to replace the hammer with the special tools provided. It takes only one shift to replace the set of hammers. The replacement of the bottom grinding chamber grinding rod can also take only tens of minutes, which greatly reduces the time and cost of inspection and maintenance. The hammer crusher has more than 100 hammers. It takes a lot of time and manpower to replace a set of hammers, and the maintenance and maintenance costs are high. The replacement of the bottom screen is also extremely troublesome.

Curtain Wall Profile Extrusion Dies

Aluminum profile curtain wall is a building curtain wall system that uses aluminum profiles as the main material. Aluminum curtain walls are lightweight, corrosion-resistant, and highly malleable, and are suitable for various building types.

The structure of the aluminum profile curtain wall mainly consists of an aluminum profile frame, fillers of glass or other materials, and connectors. Aluminum profile frames can be processed into various shapes and sizes according to design needs to meet the requirements of the building's appearance. Fillers can choose different types of glass, metal plates, stone and other materials to achieve different visual effects and functional requirements. Connectors are used to connect aluminum profiles and fillers to ensure the stability and safety of the entire curtain wall system.

Aluminum profile curtain walls have good heat insulation, sound insulation, waterproof, windproof and other properties, and can effectively protect the internal environment of the building. At the same time, aluminum profile curtain walls also have the advantages of easy installation, convenient maintenance, and long life, and are suitable for exterior wall decoration of various buildings.

In short, aluminum profile curtain wall is a building curtain wall system with complete functions and beautiful appearance, which is widely used in various building types such as commercial buildings, office buildings, and residential buildings.
