GP330 Cone Crusher: Specification and Working Principle Analysis

1. Specification Details of GP330 Cone Crusher

The GP330 cone crusher performs outstandingly in the industrial field. It weighs 16,600 kg (36,600 lbs). The robust body ensures the stability of the equipment during operation, effectively reducing vibrations and ensuring efficient production. In terms of power, it is equipped with a powerful 250 - 315 kW (325 - 425 hp) power supply. This enables it to easily handle the crushing of various hardness materials, from hard iron ore to relatively soft limestone, achieving high - efficiency crushing.

The maximum feed opening size of the GP330 cone crusher reaches 215 mm (8 15/32"). The larger feed opening allows larger pieces of materials to directly enter the crusher, reducing the pre - treatment process of materials and improving the overall production efficiency. It also has a rich selection of eccentricities, including 18, 22, 25, 28, 32, 36, 40 mm (11/16, 7/8, 1, 1 7/64, 1 ¼, 1 13/32, 1 9/16"). Users can flexibly adjust the eccentricity according to actual production needs, such as material characteristics and expected crushing particle sizes, to precisely control the crushing effect. In terms of production capacity, the GP330 cone crusher can reach a maximum production capacity of 420 Mtph (462 Stph). Such a high production capacity gives it a significant advantage in large - scale production operations.

2. Working Principle of Cone Crusher

The working principle of the cone crusher is based on extrusion crushing. Its core components include a fixed cone and a moving cone. The motor drives the eccentric sleeve to rotate, and the movement of the eccentric sleeve makes the moving cone perform a swinging motion. During this process, the moving cone sometimes approaches the fixed cone and sometimes moves away from it.

When the moving cone approaches the fixed cone, the materials between the two cones are subjected to strong extrusion, bending, and shearing forces. The materials are gradually crushed into small pieces under this high pressure. As the moving cone continues to swing, the crushed materials are discharged downward from the gap between the two cones under the action of gravity. When the moving cone moves away from the fixed cone, it provides space for new materials to enter the crushing chamber.

The GP330 cone crusher further improves the crushing efficiency and effect by optimizing the structural design of the fixed cone and the moving cone and adjusting parameters such as the eccentricity. For example, a reasonable moving cone angle and eccentricity setting can make the materials in the crushing chamber be more evenly and effectively extruded, thereby increasing the crushing ratio and producing products with more uniform particle sizes.

In conclusion, the GP330 cone crusher, with its excellent specification parameters and efficient working principle, plays an important role in the industrial crushing field and provides strong support for various production activities.
