Cetabular wall and rolling body bushing wear fault diagnosis of partial acetabular wall and the body roll caused by partial bushing wear is mainly the result to the discharge port of the centerline and the center line of the same crusher, feed through the mouth of the material flow geometry center line and center line to the spout is inconsistent, the main feed material flow only through the feed port to the discharge port cross-sectional area of 2 / 3. Thus, in the sub-tray on the center line of the cone-shaped pile of materials and material through the mouth of the stream feeding the geometric center line do not coincide. Thus, the sub-tray in accordance with the crushing chamber can not be balanced distribution of materials, most of the materials are expected to flow into the crushing chamber side, resulting in rolling acetabular wall and the partial body bushing wear. Troubleshooting will spout mobile 100_150mm (see Figure), the material through the mouth of the stream feeding the geometric center line and broken line machine centerline. In this way, points on the conical tray material evenly distributed in accordance with the crushing chamber to meet the acetabular wall and rolling body bushing wear the uniform.
Feeding funnel plug troubleshooting arch arch plug feeding funnel by internal friction between particles, attached to the funnel shape of the irrational and the result of other factors combined. The cone crusher feed hopper and feeding the mouth of the transition, the first face to form right angles (see Figure), whose purpose is to use fill material into a dip, to prevent the direct impact of the material to protect the hopper wall. However, due to the uneven particle size, especially in some of the sheet and strip the ore, the weight of overlap here, resulting in arch plug, to the operator to bring a great deal of inconvenience and insecurity, affecting the normal operation of the device. Troubleshooting will hopper front side plus a sloping curved liner 3, the arc of the liner material falls freely along the slide to the material lining the mouth. This method can effectively solve the feed problem drain plug brackets.
Cone head and spindle loose connection troubleshooting cone head and spindle connection, the original design is threaded connection, but often loose in operation. Analysis of its causes, mainly due to the conical head of the fastening bolts loose after opening time can not be found, resulting in head and spindle with the cone is not tight. In the moving deflection cone, the cone head screw and the outer threaded spindle relative motion occurred, again and again, the thread had worn, resulting in a broken wall loosening and loss of zinc alloy, will be severe wear on the spindle thread bad, so maintenance workload. Troubleshooting When the conical head used to a certain time, planned according to the actual size of the threads on the spindle, the conical head of the internal thread welding for assembly processing. Cone head assembly, the use of the lifting screw spindle, processing a specially crafted bolt 7 and a conical plate 6, the conical head pressed again (see Figure). Distribution in the conical plate and leave enough space between the plate, rubber pad to plate 5, to play a buffer role. This method does not change the original structure, with good results.
