This spring cone crusher is typically designed to process a variety of mid-hard and above mid-hard ores and rocks in different fields, like metallurgy, construction, road building, chemistry, etc.
When compared with jaw crusher, the spring cone crusher has more advantages, such as stable structure, high production efficiency, convenient adjustment, lower operational costs, and more. Its spring safety system is used as the overload protection system to allow foreign iron lumps to get through the crushing chamber without damage to the crusher. Both glycerin and water sealing modes are employed to separate the stone powder and lubrication oil, thus achieving stable and reliable operation. The shape of the crushing chamber is decided by the size of feeding material. The standard form is suitable for medium crushing, and the medium and short ones is appropriate for fine crushing.
Materials become squeezed and crushed between the movable and fixed cones. So the spring cone crusher is more advanced and efficient than the jaw crusher. Its movable cone is held by the spherical bearing, and the fixed one by a hanging erect shaft that is set in the eccentric sleeve of the stop and push bearing.
Both the movable cone and erect shaft are driven by the eccentric shaft sleeve. And the eccentric shaft sleeve is driven by horizontal shaft and fabricated gear, and the wheel of conveyor belt is directly driven by motor via the v-belts. The lower part of vertical shaft is fitted in the eccentric sleeve. When the eccentric sleeve rotates, a conical surface forms. Once the movable cone moves near the fixed one, rocks and ores are broken, and when the movable cone leaves, crushed material will be discharged. Besides, the fixed cone can go up and down in order to adjust the width of discharge hole.
