Condition: new, functionality: fully functional, fuel type: electric, Year of construction: 2026, Spring & Hydraulic Cone Crusher: Design, Operation, and Technical Insights Cone crushers are vital in mining, metallurgy, and aggregate production, designed for secondary and tertiary crushing of hard and medium-hard materials. Among the most common types are the spring cone crusher and the hydraulic cone crusher, each offering distinct advantages in structure, performance, and control. Spring Cone Crusher The spring cone crusher is a traditional design that uses mechanical spring systems for overload protection. When uncrushable material enters the crushing chamber, the spring mechanism allows the bowl liner to move downward, preventing damage to the crusher. Once the foreign object passes, the springs restore the original position, ensuring continuous operation. Structural Composition: Main frame and base assembly Eccentric shaft and transmission system Fixed and moving cones (mantle and concave) Spring and adjustment mechanism Working Principle: Material is fed into the crushing chamber and compressed between the mantle and concave. The laminated crushing principle ensures that particles are crushed by both impact and pressure, producing uniform and well-shaped aggregates. Hjdpfxetxhybo Akyen Technical Highlights: Feed size: ≤300 mm Discharge size: 3–60 mm Capacity: 30–700 t/h Motor power: 75–400 kW Advantages: Simple structure, low maintenance cost, stable performance, and reliable overload protection. Applications: Widely used in crushing granite, basalt, iron ore, copper ore, and limestone. It is suitable for medium-scale operations where cost efficiency and durability are priorities. Hydraulic Cone Crusher The hydraulic cone crusher is an advanced evolution of the spring design, integrating hydraulic systems for improved automation, safety, and precision. It replaces the mechanical spring system with hydraulic cylinders that control the discharge opening and provide overload protection. Structural Composition: Main frame and eccentric assembly Hydraulic cylinders and control system Crushing chamber with optimized liner design Automatic lubrication and hydraulic adjustment units Working Principle: The hydraulic system adjusts the discharge opening and releases pressure automatically when uncrushable material enters. This prevents mechanical damage and allows the crusher to resume operation quickly. The combination of high-speed eccentric motion and optimized chamber geometry enhances crushing efficiency and product quality. Technical Highlights: Feed size: ≤320 mm Discharge size: 3–50 mm Capacity: 45–1200 t/h Motor power: 90–630 kW Advantages: Automatic cavity cleaning, precise control, high crushing ratio, and superior particle shape. Applications: Ideal for large-scale mining, aggregate production, and high-demand crushing lines requiring consistent output and minimal downtime. Comparative Overview Both crushers operate on the same compression principle but differ in control and automation. The spring cone crusher offers simplicity and cost-effectiveness, making it suitable for stable working conditions. The hydraulic cone crusher provides advanced control, faster adjustment, and higher efficiency, ideal for modern, large-capacity plants.

It allows the metal plate to be fed in one single pass, completing pre-bending and roll forming of the workpiece without the need for turning over the plate. The upper working roller serves as the main drive roller, while the lower roller and two side rollers are hydraulically driven. Their lifting strokes are controlled by the CNC system, enabling automatic leveling with a synchronous display accuracy of ±0.1 mm. The tilting and resetting of the tilting bearing housing adopts a hydraulic transmission structure, and the upper roller is equipped with a balancing mechanism to facilitate the removal of the finished workpiece. The machine comes with a movable independent control console for flexible repositioning at any time, and is equipped with safety interlock devices to ensure safe and reliable operation. Working Roll Material The working rolls are made of 42CrMo high-strength premium alloy steel, manufactured through forging, rough machining, and quenching & tempering heat treatment, achieving a bulk hardness of HB 240–300. After finish machining, they undergo medium-frequency induction hardening, resulting in a surface hardness of HRC 47–58. The products comply with the JB/ZG4289-86 standard for roll steel, ensuring uniform roll rigidity with a controlled deflection of (1/700–1/1000)L. Note: L refers to the center distance between the two side frames. The entire production process strictly follows the standard manufacturing flow for rolls, fully guaranteeing the comprehensive mechanical properties of the working rolls. Hsdpfxjy Ugtaj Akyen Working Roll Rotation & Drive System The upper roll is the driving roll of the four-roller rolling machine. It is fitted with an independent hydraulic motor directly coupled to the heavy-duty gear housing, with no intermediate gear transmission. This is the most energy-efficient drive design. The hydraulic motor is equipped with an instant braking device, enabling accurate positioning of the roll shaft during pre-bending operations. Double-row spherical roller bearing Excellent Self-aligning Performance The outer ring adopts a spherical structure, allowing the inner ring and roller assembly to deflect within an angle of 1.5°~3°. It can automatically compensate for misalignment caused by installation errors and shaft deflection, preventing seizure and abnormal wear. Heavy Load & Impact Resistance Line contact between rollers and raceways enables the bearing to withstand extremely high radial loads as well as bidirectional axial loads, perfectly suited for heavy-duty working conditions of rolling machine rolls. High Durability Made of high-strength bearing steel with quenching and other heat treatments. Combined with a well-designed lubrication system, it ensures long-term stable operation under harsh conditions and greatly reduces downtime for maintenance.
