CV229VSI Impact Crusher, as an efficient and multi-functional crushing equipment, its core lies in the adoption of the advanced vertical shaft impact crushing principle. This principle enables the machine to work with the huge centrifugal force generated by the high-speed rotor, which will accurately and forcefully project the materials to the well-designed impact liner. In this process, the materials and the impact liner, or between the materials, will be violently impacted, thus forming a unique ‘stone hitting stone’ or ‘stone hitting iron’ impact crushing mode. This unique crushing mode not only ensures that the material is fully and evenly crushed, but more importantly, it achieves a high percentage of cubic particles. This is undoubtedly a huge advantage for the industry in pursuit of high quality crushing products. This is because cubic particles not only have a more regular appearance, but are also more capable of meeting specific process requirements during subsequent use and processing.
In order to further enhance the durability and crushing efficiency of the equipment, the rotor structure of the CV229 VSI Impact Crusher has been carefully optimised and designed. The rotor is also made of high strength alloy hammers, which, with their excellent hardness and wear resistance, enable the rotor to withstand the continuous impact and abrasion of hard materials (e.g. granite, iron ore, etc.), thus greatly extending the service life of the equipment.The CV229 VSI Impact Crusher is also equipped with a fully hydraulic drive system. This system not only makes the operation of the equipment easier and more flexible, but more importantly, it supports quick adjustment of the clearance of the impactor frame. This means that users can easily switch between coarse and fine crushing modes according to actual crushing needs, thus meeting different production requirements.The CV229 VSI impact crusher also shows great convenience in terms of maintenance. The modular design of the wear parts means that when the wear parts need to be replaced, the user does not need to dismantle the whole unit, but only partially replace it. This design not only greatly simplifies the maintenance process, but also significantly shortens the maintenance time, thus ensuring that the equipment can continue to operate efficiently.

CV229 Impact Crusher Advantages

High-efficiency crushing and particle shape control technology

In modern industrial production, crushing equipment plays a crucial role. Among them, the equipment adopting the impact crushing principle has become the first choice in many fields due to its high efficiency and precise crushing ability. This kind of equipment realises rapid crushing of materials through multi-stage impact between the high-speed rotor and the impact plate. Compared with the traditional equipment, its processing capacity has been significantly improved, and it can complete the crushing of a large amount of materials in a shorter time. More importantly, this kind of impact crushing equipment also excels in crushing effect. The crushed material shows cubic granularity with extremely low needle flake content and uniform particle size. This feature makes this equipment has a unique advantage in the production of high-grade engineering aggregates. Whether it is highway construction, railway construction or large-scale water conservancy projects, a large amount of high-quality aggregate is needed as a support, and the impact crushing plant is the ideal choice to meet this demand.

Flexible Adjustment and Wide Adaptability

In order to meet the diversified needs of different users, the impact crushing plant is designed with flexibility and adaptability in mind. Users can easily control the particle size range by adjusting the rotor speed, the gap of the impact plate or replacing the grinding chamber liner. This flexibility makes the equipment applicable to the crushing treatment of a wide range of materials, whether it is medium-hard materials or higher hardness materials, such as limestone, granite, coal gangue, etc., can get the ideal crushing effect. The equipment also performs well in handling materials with large moisture content. This is often a problem in the traditional crushing equipment, because the wet material is easy to stick in the crushing chamber, affecting the crushing efficiency and effect. With its unique crushing principle and structural design, the impact crushing plant has successfully overcome this problem.

Double guarantee of energy saving and durability

In terms of energy saving, the impact crushing plant has also made significant contributions. The impact crushing method it adopts effectively reduces ineffective energy consumption, making the power consumption per unit output much lower than similar equipment. This not only reduces the operating cost, but also meets the urgent demand for energy saving and emission reduction in the current society. At the same time, in terms of durability, the equipment is also outstanding. Key components such as high chrome alloy hammers and impact liners are made of highly wear-resistant materials. The wear resistance of these components has been increased by more than two times, and the metal utilisation rate has reached 45-48%. This means that the maintenance frequency of the equipment is greatly reduced and the service life is effectively extended.

Convenience of structure and maintenance

From the perspective of structural design, the impact crushing plant adopts a modular design concept. This design concept greatly simplifies the dismantling process, making it easier and faster for users to maintain and replace parts. At the same time, key components such as the rotor, impact plate and other standardised parts are adopted, which further shortens the downtime for maintenance and improves the overall operating efficiency of the equipment. In addition, the vibration control system and sealing structure have been optimised. These optimisation measures effectively reduce the risk of abnormal downtime during operation and improve the stability of the equipment. The equipment can maintain stable operation for a long time, even in harsh working environments.

Excellent environmental performance

In today's society, environmental protection has become an important issue that cannot be ignored. The impact crushing plant also makes positive contributions to environmental protection. It is equipped with advanced sealing device and silencer, which effectively reduces the dust spillage and noise generation during operation. This makes the noise level of the equipment in line with industrial environmental protection standards, which is of great significance to the protection of the environment and the health of employees.

CV229 Impact Crusher Working Principle

When the CV229 VSI Impact Crusher receives the start-up command, the whole plant begins to enter the working state. Firstly, the power supply is switched on and the motor starts to run and gradually accelerates its rotation. This process is not a simple direct start, but involves a complex transmission system. Specifically, the motor is connected to the rotor through a triangular belt, and when the motor rotates, it will drive the rotor to rotate together through the triangular belt. This process takes some time to reach a steady state of operation, so there is usually a warm-up and acceleration phase, which can be 10 minutes or more, to ensure that the rotor is able to reach the required operating speed.
Once the rotor has reached a stable working speed, the stone can start to enter the crusher. The stone material is conveyed via a conveyor belt to the feed opening and then into the first crushing chamber of the crusher. Inside the first crushing chamber, the materials receive their first crushing. The high-speed rotor hammers are designed according to the collision theory and have strong crushing ability. When the materials collide with these hammers, the large stone materials less than 300MPa will be quickly crushed into small pieces. These small pieces of material will not stop moving immediately after the collision, but will continue to counterattack to the liner of the impact plate, and at the same time will also collide with other stone materials. This kind of multi-stage collision and repeated impact greatly promotes the crushing process, so that the material can get the initial crushing effect in the first crushing chamber.
After being processed in the first crushing chamber, most of the stone materials have been crushed and cracked, but occasionally there are still some large stones that are difficult to be crushed. At this time, the rotor will play its pushing role to push these big stone materials into the second crushing chamber. Inside the second crushing chamber, the stone materials are once again welcomed to impact. But this time the impact is stronger, because the stone material has increased its speed under the centrifugal force of the rotor body. When the stone materials hit the second impact plate, they are further crushed. During this process, the particle size of the stone material decreases and gradually approaches the requirement of the final product.
Finally, when the crushed stones are smaller than the height of the grating holes of the third impact plate, they can leak out through these grating holes and become the final products. These final products have uniform particle size and good shape, which can meet the requirements of various industrial applications. As for those stones which are still larger than the gates, they will be further crushed in the third crushing chamber until they meet the particle size requirement before they can be discharged through the third gate.
