CS420 cone crusher, as a medium-sized crushing equipment with excellent performance, shows its unique advantages in processing capacity and crushing effect. In terms of processing capacity, CS420 cone crusher is divided into two types: standard type and short head fine crushing type. The processing capacity of the standard type ranges from 22-128 tonnes/hour, which is suitable for crushing materials with medium hardness; while the short-head fine crushing type is more powerful, with a processing capacity of 70-168 tonnes/hour, which is especially suitable for high hardness materials or scenes requiring fine crushing treatment. In addition, the size of the feed opening of the equipment is also different, the standard type ≤ 135mm, short head type ≤ 240mm, some models even support ≤ 369mm larger materials, further broadening its scope of application. The CS420 Cone Crusher also excels in discharge opening adjustment and discharge size control. With a wide range of discharge opening adjustments, from 4-38mm, users can make flexible adjustments according to actual needs. The discharge size can be controlled between 3-64mm, which ensures the uniformity of the crushed product size and quality stability. This advantage is due to the laminar crushing technology adopted by the equipment, through the optimisation of the cavity type and pendulum frequency, which not only improves the crushing efficiency, but also effectively reduces the proportion of needle-flake particles, so that the crushed products are more in line with the market demand.
In order to meet the needs of different materials and working conditions, the CS420 Cone Crusher also supports a variety of cavity configurations, such as ultra-coarse, medium-coarse, fine, and so on. Users can choose the appropriate cavity type for crushing operation according to the hardness and particle size distribution of materials to achieve the best crushing effect and economic benefits.
In terms of equipment design, CS420 Cone Crusher adopts single-cylinder hydraulic design. This innovative design not only simplifies the structure of the equipment, but also integrates hydraulic adjustment of the discharge opening and overload protection function. Users can quickly adjust the discharge opening by simple operation, which greatly improves the working efficiency. Meanwhile, when the equipment encounters an overload situation, the hydraulic system will automatically activate the protection mechanism to avoid damage to the equipment, ensuring the safety and stability of production. In practical application, CS420 cone crusher is often combined with jaw crusher (e.g. PE600×750) or sand making machine (e.g. DLKZS1314) to form a multi-stage crushing line. Such a combination not only improves the crushing efficiency, but also ensures the stability and continuity of the crushing process. The jaw crusher, as the primary crushing equipment, is responsible for crushing large materials into smaller sizes, and then these materials are fed into the CS420 cone crusher for further fine crushing. Finally, the sand making machine is responsible for processing the finely crushed materials into sand or stone that meets the requirements. Such a multi-stage crushing line not only improves the production efficiency, but also ensures the quality and particle size distribution of the products.

CS420 Cone Crusher: a crushing tool with large feed and high production capacity Working Principle

This crushing plant adopts a unique single-cylinder structure, and its working principle is mainly based on the principle of extrusion crushing to achieve the crushing treatment of materials. In this sophisticated design, the moving cone plays a crucial role. It performs a series of periodic rotary oscillating movements driven by a well-designed eccentric sleeve. This movement creates a powerful crushing zone between the moving cone and the stationary cone, and any material entering the crushing chamber is subjected to strong impact and crushing action, resulting in effective crushing.
To drive this complex crushing mechanism, the motor is closely connected to the eccentric sleeve via a pulley or coupling, ensuring that the sleeve rotates smoothly and efficiently. As the eccentric sleeve rotates, it drives the main shaft and the cone in a pendulum motion around a fixed point. This pattern of motion causes the surface of the cone to move periodically closer to or further away from the cone, thus achieving continuous crushing of the material.
The materials enter the crushing chamber from the top of the crusher, and as soon as they enter this area, they are subjected to strong squeezing, bending and grinding forces between the moving cone and the fixed cone. These combined forces cause the material to be gradually crushed into smaller particles. Once the materials reach the required size, they will be discharged smoothly from the bottom discharge port of the crusher by gravity. Those materials that do not reach the required size will remain in the crushing chamber for further crushing until they meet the requirements. The crusher also has a built-in spring-loaded compression mechanism. The main purpose of this design is to protect the equipment from unbreakable materials. When some hard foreign objects (such as metal pieces) accidentally enter the crushing chamber, the spring will be compressed and deformed, thus enlarging the discharge opening, so that these foreign objects can be discharged smoothly, avoiding damage to the equipment. Overall, this crushing plant achieves fast and effective crushing of materials with its unique single-cylinder structure and efficient crushing principle of extrusion. Meanwhile, its built-in spring compression mechanism also provides a strong guarantee for the stable operation of the equipment. Whether dealing with hard ores or other types of materials, this crushing plant can show its excellent performance and reliability.
