Gyratory crushers are widely used in large and medium-sized concentrators in my country, and are often used for crushing hard ores. This equipment is a large-scale crushing machine that mainly uses the gyration motion in the cone cavity of the crushing cone to produce squeezing, chopping and bending effects on the materials, and coarsely crushing various hardness of ores or rocks. The installation of the gyratory crusher includes five parts: the installation of the lower frame, the installation of the transmission part, the installation of the eccentric shaft sleeve, the installation of the middle frame, the installation of the crushing cone and the beam, the installation steps and specific measures of the machine as follows:
    1. Installation of the lower rack
    The installation of the lower rack is the basis for equipment installation. Install the lower rack on the foundation *, and the equipment be consistent with the foundation during installation. A gap of not less than 30mm should be kept between the base of the lower frame and the foundation due to secondary grouting. Tighten the anchor bolts after the second grouting to ensure the stability of the equipment.     2. Installation of the transmission part
    The installation of the transmission part is related to the operation of the equipment. Therefore, when installing, it be noted that the centers of the two copper sleeves always be kept at the same horizontal line without deviation. The radial gap between the copper sleeve and the shaft be strictly in accordance with the instructions of the equipment manual. Within a certain range. When installing the drive shaft, it is necessary to add an appropriate amount of gaskets between the flange of the drive housing and the frame to adjust the position of the bevel gear to meet the product design requirements.
    3. Installation of eccentric shaft sleeve
    Special attention should be paid to the installation process to protect the smoothness and integrity of the friction surface of the babbitt alloy layer. Check whether the tooth tip clearance meets the requirements after installation, and correct it in time if any abnormality is found. The size of the gap can be adjusted by changing the number of adjustment shims.
    Fourth, the installation of the middle rack
    The installation of the middle frame needs to be calibrated through the upper flange of the lower frame. Before installation, it is necessary to make sure that the gap between the flanges of all the taper surfaces is equal, and the error should be less than 0.5mm. The gap between the upper and lower joint surfaces is generally about 15 mm.
    When installing, make sure that the pins are tightened. After the machine has been running for a period of time, tighten the pins one by one to make all the pins on the circumference evenly stressed, strengthen their stability, and ensure the normal operation of the equipment.
