How jaw crusher is to achieve security and jaw crusher thrust plate adjustable discharge mouth (also known as brackets), in addition to passing the power to make the movable jaw plate do swing back and forth outside the mine grader, also has a security role as insurance, change Its length can also play a role in regulating port of discharge. When the jaw crusher cavity can not break into the matter (such as iron ball, iron, etc.) grader, after the main components in order to protect the device from damage and the use of thrust plate as the crusher assurance member. After the thrust plate is generally made of cast iron cast as a whole, in which the department to open a groove or a plurality of apertures to reduce its cross-section strength; also cast two, then connected by screws (or rivets), consisting of a combination of thrust plate. When not broken material into the crushing chamber rounds grader, equipment overload, huge crushing force to cause the thrust plate thrust plate fracture or a combination thrust plate screws cut, the machine stopped working, play a role as insurance. With the constant wear and tear tooth plate, port of discharge becomes larger biaxial grader, constantly thicker, in order to obtain qualified product size, require periodic adjustment of discharge opening size. Adjustment of discharge ports are the following two ways: (1) shims that support seat in the back of the back pressure plate between the frame rear wall and put a set of gaskets, shims or change the number of its thickness , you can achieve the purpose of adjusting the port of discharge. This method is compact structure, regulate reliable, large and medium-sized jaw crusher and more with this adjustment method. (2) wedge adjustment, is placed between two wedges thrust plate between the rear seat and chassis adjustment, suitable small crusher. Mill Drive partially correct installation process is well known that there are a lot of ball component parts, here we introduce the method is to install its transmission part, as follows: 1. Check the large and small gear parallel to the centerline, and its imbalance must not exceed the standard requirements . 2, check the big backlash of the pinion, its value should be guaranteed in the 0.4-1.2mm range, exposure of tooth surfaces painted inspection applications, the contact length of not less than 50% of tooth length, then angle height of not less than 60% The tooth height. These requirements by means of screwing the adjusting screw, change the horizontal centerline position and the gear box to achieve a vertical direction can be used to adjust the wedge calibration. 3, deceleration mounting machine, should ensure that the axis of the shaft with the two at the same level, misalignment and tilt speed shaft and the gear shaft may not exceed the technical requirements of each. 4, the installation of the motor should be well reducer to be calibrated, two different concentric shaft must comply. 5, the gear cover should be installed to ensure that the inner wall does not collide with the large gear.
