As the broken tooth plate continues to wear, the discharge port of the jaw crusher gradually increases, and the product size becomes coarse. In order to reasonably balance the load of each crusher and ensure the particle size requirements of the crushed product, it is necessary to periodically measure and adjust the discharge port of the crusher, and measure and adjust it 3 to 4 times per week depending on the specific conditions. Check ball discharging opening common lead (column block) or soap bars assay. Lead weights soon cast balls or cylinders, when measured in order to facilitate holding, in the cast iron wire ball (column) engaging, in order to put into the crushing chamber with the hand and, on the ball to be movable jaws (column) after the nip It is pulled out from the crushing chamber, and the thickness of the squeeze is measured by a caliper, which is the width of the discharge port of the crusher. If the width of the measured discharge port does not match the width required by the process, it should be adjusted. It must be noted that when measuring the discharge port, it is carried out under an empty load. The jaw crusher uses an adjustment device to adjust the size of the discharge port. There are two types of adjustment devices: 1. shimming    Place a set of gaskets of the same thickness between the rear wall of the frame and the wedge iron (shown below), and increase or decrease the thickness of the gasket layer to reduce or increase the discharge port to adjust the discharge port. the goal of. This method can be adjusted in multiple stages and is easy to operate, but it must be adjusted. Generally used for large and medium-sized jaw crushers, the simple swing jaw crusher uses this adjustment device. 2. Wedge iron adjustment    It is realized by a wedge-type adjustment mechanism (shown below). It is adjusted by means of two wedge irons placed between the elbow bracket of the rear bracket and the rear wall of the frame. When the nut is screwed and the rear wedge is raised along the rear wall of the frame by the screw, the front wedge iron is along The guide grooves parallel to the side walls of the frame move forward, thereby pushing the toggle plates and the moving jaws to move forward, thereby reducing the discharge opening. This method can achieve stepless adjustment. The adjustment is convenient and time-saving, and does not need to stop, but the disadvantage is that the size and weight of the machine are increased, and it is not easy to adjust the level, and the bracket and the connecting rod are twisted, so the adjusting device is only suitable for the small and medium-sized jaw crusher. This type of adjustment device is often used in complex oscillating crushers. Aircraft Engines Honeycomb Seals Honeycomb sealing can produce good sealing effect, reduce airflow loss, and improve aerodynamic efficiency. The Honeycomb Seal at the top of the blade also has a good dehumidification effect, which can effectively protect the blades from erosion by water vapor.
