As we all know, cone crusher is a kind of crushing equipment with large crushing ratio and high production efficiency. It is far superior to impact crusher, jaw crusher, etc, in the field of medium and fine ore crushing. As far as the current cone crusher market is concerned, it is mainly divided into spring cone crusher and hydraulic cone crusher. It is difficult for many mining investors to tell the difference between the two.
Next, SMMVIK Machinery will tell you the difference for your convenience.
1. Hydraulic adjustment. Automatic hydraulic adjustment of hydraulic cone crusher and manual hydraulic adjustment of spring cone crusher.
2. Working principle. The operation of the hydraulic cone crusher is to drive the pulley, transmission shaft and cone part to make the eccentric shaft rotate and swing periodically under the axis line through the rotation of the belt conveyor. After the material enters the crushing chamber from the material mouth, it is impacted, ground and rubbed by the eccentric shaft and the rolling mortar wall.
The spring cone crusher drives the transmission shaft and cone to make the eccentric shaft swing periodically under the axis line through the rotation of the belt conveyor. After the material enters the crushing chamber from the material mouth, it is impacted by the eccentric shaft and the rolling mortar wall, kneaded and ground, and then crushed.
3. Discharge port. The discharge port of the hydraulic cone crusher is realized by driving the piston of the hydraulic cylinder. The size of the discharge port is adjusted by controlling the oil inlet and oil return of the hydraulic cylinder. As far as spring cone crusher is concerned, the adjustment of discharge port size is mainly realized by adjusting the spring.
4. Overload protection. The hydraulic system of the hydraulic cone crusher is convenient and reliable, saving time and labor in repair, and can provide safe and useful overload maintenance effect. When the machine has iron defects or is stuffy, the support sleeve and the top of the fixed cone are cleaned by hydraulic pressure, which greatly reduces the repair rate and improves the production power with good insurance effect. The spring safety device of the spring cone crusher can also protect the equipment, and the equipment is sealed with grease, which can effectively avoid water oil mixing.
