Cone crushing is a popular machine equipment in the field of mining and crushing at this stage. It is widely used in the industry, with good characteristics and low cost. In mining production and manufacturing, cone crushing is generally used for crushing rate and various raw materials. As we know, the feed size of the cone is determined by the distance between the crushing wall and the rolling mortar wall. However, many people do not grasp the device for adjusting the distance between the two. Today, I will come to know three types of cone breaking adjustment devices: fixed pulley adjustment device, hydraulic pusher adjustment device and Hydraulic motor Adjustment device.

Fixed pulley adjustment device

The fixed pulley adjusting device refers to crossing the fixed pulley with a rope, Special hydraulic motor for construction machinery It is wound on the sound card rack, the tail end is hung on the hook, and the other end is driven by an external lifting machine to rotate the adjustment sleeve, thus changing the spacing between the crushing wall and the rolling mortar wall. The broken crushing wall and rolling mortar wall of the torsion spring cone are seriously damaged. When it is necessary to replace them, this kind of method should be used to screw out the upper part of the human body, and then remove and replace two jaw plates. When the adjusting torsion spring cone is broken, Low speed high torque hydraulic motor The torsion spring is used to expand the particle size distribution of the feeding port, and the lengthening torsion spring is used to reduce the particle size distribution of the feeding port. The effect of the adjusting sleeve is to stretch or torsion spring.

Hydraulic pusher adjustment device

The basic principle of the adjustment of the hydraulic pusher adjustment device and the fixed pulley adjustment device is the same. It is all based on the promotion of the rotation of the adjustment sleeve to push the extension or reduction of the torsion spring, and then adjust the size distribution of the feed at the blanking port. Only the hydraulic pusher adjustment method is not fixed pulley, nor rope. Only two hydraulic pushers must be used to start the driving force, which can promote the rotation of the adjustment sleeve, and then adjust the size of the blanking port. The two kinds of blanking opening adjustment devices for the broken torsion spring cone have a certain level of convenience. It is relatively convenient to adjust the size of the blanking opening with a hydraulic pusher than with a fixed pulley. However, when the broken torsion spring cone is replaced with wear-resistant materials, namely, the crushing wall and the rolling mortar wall, it is more time-saving and labor-saving to use a sliding plate device to replace it. Because the hydraulic pusher is slow, customers can rely on their own needs, Feel free to choose.
