After the user purchases the cone crusher, in order to ensure the production life and the efficiency of the operation, the equipment is tested at intervals. So what are the testing tasks of the cone crusher?The general inspection time is started after the equipment is finished, and it is cooled for five or six hours. The inspector firstly checks the flatness of the conical surface to see if there is any unevenness. If so, inform the technician to make the transformation. It is found that unqualified parts or parts with deviations should be replaced in time.The counterweight of the large bevel gear of the cone crusher is to eliminate the inertial force and moment of inertia of the direction change caused by the crushing cone. Due to the limitation of the size of the crusher, the inertial force of the crushing cone cannot be completely eliminated. Therefore, when the crushing cone rotates, a large unbalanced inertial force is generated. This unbalanced inertial force is caused by the crusher frame and the basic vibration. Disturbance. That is, the disturbance of the crusher is the unbalanced inertial force generated when the crusher's crushing cone rotates around the central axis.The cone crusher is an important ore dressing equipment with relatively large body shape. During its operation, the wear of the parts will seriously affect the vibration stability of the crusher, and at the same time, the machine will be in a state of forced vibration for a long time, which will seriously affect the crushing. The safe operation of the machine. The study found that the disturbance is an important factor affecting the forced vibration of the crusher. Let us analyze it here.For the operation of the empty machine with a cone crusher, before starting the machine, check whether the equipment is installed well. Everything is normal before it can be turned on. During the empty operation, it is necessary to check the sealing, jamming, friction, and impact of the equipment. . During the trial rotation, check whether the cylinder body has obvious sway, whether there is too much noise, ensure that the cylinder sway does not exceed 0.5mm, and the noise is controlled within 85db. After the cone is broken and put into formal work, the staff needs to insert the special thermometer for the rolling bearing into the oil control of the bearing seat, and measure it once every hour, knowing that the temperature is stable.
