About jaw crusher equipment, Xiaobian has always emphasized that we should investigate more, understand more, and choose reliable manufacturers. Why do you say that? Because some devices will have various problems during use. Take the problem of jaw crusher return material. In the production process, the phenomenon of material return is generally divided into the following reasons.
1. The length, thickness of the jaw plate, the length of the elbow plate, the Angle of the elbow plate, the size of the frame cavity and other broken parts are inconsistent with the drawing size, resulting in poor machine quality. After long-term use, the Angle between the two jaw plates is more than twice the friction Angle, so that there is not enough friction between the material and the jaw plate to overcome the upward force of the crushing force, and the material is squeezed under the influence of the vertical upward force and slides the inlet direction.
2. When the material is stressed in the vertical direction of the crushing chamber, it is easy to return the material under the upward component force under the action of the upper and lower force of the movable jaw plate.
3. Many outsiders believe that the wider the discharge port of the jaw crusher, the better. In fact, if the jaw of the same specification is broken, the wider the width of the discharge port, the easier it is to return the material. In the crushing process, the material directly contacts the jaw plate to produce friction, the more serious the jaw plate wear, the greater the possibility of material return phenomenon.
4. Generally speaking, the feed size of the jaw crusher is the same to ensure uniform feeding, and when the size difference of the broken material is large, it is easy to return the material phenomenon.
Once this problem occurs, it is necessary to stop the inspection immediately. In addition, as long as you pay attention to the above problems in daily production, you can avoid the problem of returning materials as much as possible. This also ensures the normal production of the equipment. If there are equipment related questions, you can also call Shen De, we are always online for you to answer.
