Operation Error Of Foundation Installation Of Pe900x1200 Jaw CrusherLast Update:2020-05-12 23:09:46
Under the influence of economic development, the market demand of 900 * 1200 jaw crusher is increasing, especially the display of pe900-1200 jaw crusher foundation installation pictures on the Internet has been several times. Combined with the 900 * 1200 jaw breaking price that can maintain the production cost of the enterprise, the 900 * 1200 jaw crusher can really bring a big impact to the crushing equipment market.
At present, the price of 900 * 1200 jaw crusher in the market is constantly falling. On the one hand, the equipment has been put into production for a long time, and the market competition is fierce. On the other hand, there are some design defects in the installation pictures of pe900-1200 jaw crusher foundation, and the production workers will return materials due to the operation errors in the use process. This phenomenon is actually the phenomenon that the material is squeezed out of the feed port. Instead of being crushed by the movable jaw plate and the fixed jaw plate, the material is squeezed out by the two jaw plates of the 900 * 1200 jaw crusher and flies out of the feed port.
From the perspective of 900 * 1200 jaw crusher: in the front row, the foundation installation picture of pe900-1200 jaw crusher is inconsistent with the drawing size. In the processing and assembly of all parts of the equipment, if the length, thickness, length of the elbow plate and the size of the inner cavity of the rack are inconsistent with the drawing design size, it is easy to produce returned materials. Second, the width of the discharge opening of 900 * 1200 jaw crusher is too wide, and the width of the discharge opening can be adjusted, which is not entirely determined by the model of jaw crusher. For crushers of the same specification, the wider the discharge opening is adjusted, the easier it is to return.
From the aspect of materials, in the front row, the materials are under unbalanced stress. The materials to be broken are in a balanced state in the crushing cavity of 900 * 1200 jaw crusher, neither moving up nor down. However, once the angle increases, the materials are under unbalanced stress in the vertical direction, and the materials are extruded under the action of upward force. Second, there is low friction between the material and the jaw plate. The cross section of the movable jaw plate and the fixed jaw plate is of toothed shape, which can increase the friction coefficient between the material and the jaw plate of the 900 * 1200 jaw crusher, and avoid the relative movement of the material to be broken and the jaw plate as much as possible. Therefore, in the process of use, it is necessary to avoid the wear of the jaw plate and increase the friction coefficient. Third, there are different sizes of materials. If there are few large materials, the 900 * 1200 jaw crusher can still work normally. If there are many large materials and they are jammed between two small materials, the phenomenon of returning materials will inevitably occur, which is very harmful to the operation of the machine.
