Two-stage Crusher

The two-stage crusher is a high-efficiency crushing equipment. Its working principle is based on the design of dual rotors and dual-material chambers. This kind of machine crushes materials through two rotors at the same time, realizing the dual-stage crushing function of hammer powder and material powder, making the fineness of the crushed materials more uniform. Compared with traditional crushers, the output of a two-stage crusher can be increased by 50%.

Advantages of Two-stage Crusher

The two-stage crusher has become an indispensable and important equipment in the industrial field due to its efficient, uniform, and reliable crushing performance and wide range of applications.

Efficient crushing capacity

The double-stage crusher is designed with double rotors and double material chambers, which can achieve double crushing of materials, greatly improving the crushing efficiency. This design can not only handle a large amount of materials, but also the crushing effect is more uniform, which helps to improve the processing efficiency of subsequent processes.
Adjustable particle size and strong adaptability

The two-stage crusher has low requirements for material humidity and can handle materials of various humidity, such as coal gangue, shale, cinder, etc., solving the problem of wet material crushing. The crushing particle size can also be adjusted as needed to meet the needs of different users and production processes. This flexibility allows the two-stage crusher to adapt to more production scenarios.
Easy maintenance

The double-stage crusher has a reasonable structural design and is easy to maintain and repair. The operation of the equipment is stable, the failure rate is low, and it can work continuously for a long time, reducing downtime for maintenance and improving production efficiency.
Energy saving and environmental protection

During the crushing process, the double-stage crusher can reduce energy consumption and emissions through optimized design and control, achieving the effect of energy saving and environmental protection. This is an important advantage for the current industrial environment that advocates green production.

Two-stage Crusher of Application

About a double-stage crusher: The mining industry: is used to crush various ores, such as calcite, limestone, etc. Construction industry: often used to process construction waste, construction waste, and other materials.Road and railway construction: In the construction of these infrastructures, double-stage crushers are used to crush various stones and provide suitable aggregates for construction.

Coal gangue and cinder: These materials are commonly used as additives in brick and tile manufacturing, and a two-stage crusher can efficiently break them to the required particle size.

Shale: A common building material, a dual-stage crusher can reduce it to a size suitable for making bricks and tiles.

Construction waste and waste materials: With the acceleration of urbanization, the disposal of construction waste has become an important issue. The dual-stage crusher can effectively break these wastes into reusable aggregates.

In addition, the two-stage crusher is also suitable for processing slag, slag, tailings, and other raw materials with no limit on moisture content, making it an ideal crushing equipment.

Working principle

During the operation of the two-stage crusher, it is driven by dual motors, so that the upper and lower sets of rotors can rotate at high speed at the same time. When the material enters the crushing chamber, it will first encounter the crushing effect of the upper rotor. The upper rotor rotates at high speed to initially crush the materials. Subsequently, the initially crushed materials will quickly enter the working area of the lower rotor.

The lower rotor again uses the high-speed rotating hammer head to finely crush the materials. In this process, the materials will quickly collide with each other in the inner cavity and crush each other. This two-stage crushing method ensures that materials can be broken into more uniform particle sizes.

By adjusting the gap between the rotor and the lining plate, the two-stage crusher can achieve the purpose of changing the discharge particle size. This adjustment mechanism allows the two-stage crusher to produce materials that meet the required particle size according to different production needs.

In addition, the structural design of the two-stage crusher also takes into account the crushing of wet materials. By adopting a design without screening the bottom, the two-stage crusher avoids the problem of wet material clogging and improves work efficiency. At the same time, to handle materials with high humidity, the two-stage crusher is also equipped with auxiliary tools such as scrapers to ensure sufficient space during the crushing process, thereby ensuring output and crushing effects.
