A vertical mill is a kind of large grinding equipment, which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals, and other industries. It integrates crushing, drying, grinding, and grading transportation, and has high production efficiency. It can grind block, granular, and powdery raw materials into required powder materials. The vertical mill has a high value, high maintenance cost, and also brings loss of shutdown; the installation of roller bearing determines the maintenance cycle of the vertical mill to a certain extent, and the quality and installation of roller bearing play a key role. Therefore, it is necessary to select reasonable and high-quality bearings. The following is the whole process of vertical mill bearing installation.
Before installation, make a comprehensive inspection of the whole grinding roller equipment and then analyze the specific installation which needs to pay attention to.
Installation:
The Engineer shall check and approve the dimensions of the roll core, shaft, and other accessories prepared before installation. Clear a clean area for the installation of grinding roller bearing.
Take out the bearing inner ring and use an induction heater to heat the inner ring and the rolling element of the No.1 bearing for installation. Install the heated No. 1 bearing inner race onto the shaft.
Install the spacer between the 2 sets of bearings on the shaft. Using the bearing handling tool, heat the inner ring of the No. 2 bearing and install it on the shaft.
The roller core is heated by a medium-frequency heater. Handle the cover and place it on the ground smoothly. Treat the surface of the cover slightly.
Place No. 2 bearing on the blind cover. Place the spacer between the 2 sets of bearings over the No. 2 bearing outer race. Measure whether the clearance is qualified after placing the spacer sleeve.
Place the outer ring part of No. 1 bearing and the spacer in turn.
Use the vehicle to invert the shaft; and place the other part of the outer ring of No. 1 bearing.
Place the roll core on the blind cover. Place the shaft in the roll core.
Install the cover over the roll core and shaft.
The installation of a roller bearing is basically completed. In addition, we not only have the most advanced installation technology in the vertical mill but also in other equipment such as reducer bearing and roller press bearing. If you have any questions, please consult our technical service.
