Advantages of Hydraulic Cone Crushers over Spring Cone Crushers

Cone crushers are widely used in the secondary crushing process in mining and construction sand and gravel production. Over the years, the traditional spring cone crushers have evolved into modern hydraulic cone crushers. When comparing hydraulic cone crushers with spring cone crushers, the former presents several significant advantages.

1. Easier Maintenance and Shorter Downtime

Hydraulic cone crushers are equipped with hydraulic protection and hydraulic cavity - clearing systems. This feature allows for convenient maintenance and significantly reduces downtime. In contrast, spring cone crushers often require manual discharge of materials, which means the machine has to be stopped. For example, when dealing with blockages or the need to remove non - crushable objects, the hydraulic system in a hydraulic cone crusher can quickly adjust and clear the cavity, enabling the machine to resume operation promptly.

2. Superior Over - iron Protection

The over - iron protection device in hydraulic cone crushers is highly effective. When foreign objects such as iron pieces enter the crushing chamber, the protection device automatically releases the objects and then immediately resets, without affecting the normal operation of the equipment. On the other hand, spring cone crushers have a relatively short over - iron protection stroke. In some cases, this can lead to serious accidents like shaft breakage, which not only causes equipment damage but also results in long - term production halts.

3. Better Particle Shape and Less Wear

Hydraulic cone crushers adopt the principle of laminar crushing. This method utilizes the crushing force between stones, reducing the direct wear on the machine. Moreover, the finished product has a more rounded shape, effectively solving the problem of excessive needle - shaped and flaky particles in the output of spring cone crushers. The laminar crushing process ensures that the particles are crushed more uniformly, improving the overall quality of the crushed materials.

4. Reduced Blockage and On - the - go Repair

The hydraulic discharge system in hydraulic cone crushers makes them less prone to blockages. If a blockage does occur, operators can simply adjust the hydraulic system's operating valve to clear it, often without having to stop the machine. Spring cone crushers, however, are more likely to experience material blockages. Once blocked, they usually need to be shut down for repair, which can cause significant disruptions to the production process.

5. Reliable Sealing System

Hydraulic cone crushers use a sealed cylinder for dust prevention, ensuring a more reliable operation. In contrast, spring cone crushers rely on a water - sealing system, which can easily lead to the mixing of oil and water, resulting in poor lubrication and potential damage to the machine's components. The reliable sealing of hydraulic cone crushers helps to maintain the machine's performance and extends its service life.

In conclusion, based on current production practices, hydraulic cone crushers are an upgrade from years of industry development and application experience. Their performance is undoubtedly superior to that of spring cone crushers. When choosing a cone crusher, users can consider their own production requirements and budget, but it is clear that hydraulic cone crushers offer more advantages in terms of efficiency, maintenance, and product quality.
