Comparison of Single-Cylinder vs. Multi-Cylinder Cone Crushers
From the perspective of machine structure, single-cylinder and multi-cylinder cone crushers differ as follows
1. The single-cylinder cone crusher features a larger bottom cone angle and a relatively steeper crushing chamber profile, allowing for smoother material flow. In contrast, the multi-cylinder cone crusher has a smaller bottom cone angle. Due to its adoption of a fixed-shaft structure—which differs significantly from the integral shaft design of the single-cylinder model—it can operate at higher rotational speeds to achieve a high-energy, laminated crushing effect. Consequently, material undergoes a greater number of crushing cycles within the chamber. Therefore, for two machines of equivalent specifications, the throughput of the single-cylinder cone crusher is slightly higher than that of the multi-cylinder model; however, the multi-cylinder cone crusher produces a higher percentage of fine-grained material, yields a more uniform product, and generates a superior product shape (more cubic) compared to the single-cylinder crusher.
2. Both single-cylinder and multi-cylinder cone crushers allow for hydraulic adjustment of the discharge opening size.
The multi-cylinder cone crusher adjusts the opening by utilizing a hydraulic motor to rotate a large gear, thereby raising or lowering the stationary cone liner. The single-cylinder cone crusher adjusts the opening by injecting oil into—or draining oil from—the bottom hydraulic cylinder to raise or lower the movable cone liner. In practical operation, the discharge opening size of the single-cylinder cone crusher tends to fluctuate; its stability is inferior to that of the multi-cylinder cone crusher, which can negatively impact the uniformity of the discharge particle size.
3. Regarding ease of maintenance—specifically when replacing liners—the single-cylinder cone crusher requires the removal of the fixing bolts connecting the upper and lower frames, followed by the separation of the frames to facilitate the replacement. The multi-cylinder cone crusher, however, allows for liner replacement simply by using the hydraulic motor to rotate and directly unscrew the adjustment ring.
