The ball mill end cover is one of the most critical components of the ball mill, so the structure is also more complicated, the processing cycle time is long, the processing and assembly precision is very high, so in the process of programming, you need to fully consider them. Craftsmanship. The end cover is located at both ends of the barrel of the ball mill and is supported on the bearing. The main function is to support the material and the cylinder and the medium. The root rounding of the hollow shaft end plate used in the ball mill should be Concentrated parts.

So what is the relationship between the ball mill end cover and the cylinder? The end mill of the ball mill can be hung to the workshop with a 50-ton crawler. When two machines are used to lift the end cover, the lower part of the end cover needs to be between the main bearing and the flange of the cylinder, just to prevent the end. When the cover and the main bearing, the end cover and the cylinder flange collide with each other, the two sides of the end cover can be controlled. When the end cover is adjusted to the flange surface, the two sides can be controlled on both sides. In place. When the two components are assembled together, it is necessary to carefully check for errors. The assembly needs to measure the cylinder after assembly. The total length also has the center length of the two shaft diameters, which is compared with the center distance of the bearing housing. If it does not match, you need to adjust the position of the bearing housing and the main bottom plate.

When the ball mill cylinder is in place, it is necessary to first adjust the vertical and horizontal center line of the cylinder by mechanical means, then lift and lower the cylinder by the jacking device, and pass the cylinder to maintain the level, and remove the temporary steel frame. , the cylinder can be slowly landed. The end flange face of the connecting end between the end cover and the cylinder body has an annular convex surface. When the end cover is connected with the flange of the cylinder body, the end cover needs to be outwardly moved toward the bearing end as a whole. When the end cover moves with the whole outer part, the bearing bush will block the outer cover oil retaining ring from moving outward, so the main bearing bush needs to be removed before the end cover is installed.

Great Wall Cast Steel also has its own processing advantages for ball mill end covers. 1. It adopts high-quality raw materials and mature technology, coupled with rich experience in ball mill manufacturing, and the industry problems encountered in production, through our continuous improvement, enhance the wear resistance and improve the pressure resistance. The second-level flaw detection can also accurately detect the inside of the end cover, and the quality is guaranteed. 2. During the production, the end cover will make certain adjustments for the specific equipment, which can make the end cover and the feeding part more suitable. There is no gap problem, and there will be no leakage problem. 3. In the manufacturing process, it is matched with the hollow shaft. It is made of high-strength cast steel. The engineer in the early stage of the casting will be hollow on the running characteristics of the ball mill. The shaft process structure is optimized to ensure the stability and service life of the components during operation; Great Wall Cast Steel has many years of technical experience in the production of steel castings, and the production technology is becoming more sophisticated. After continuous innovation and improvement, Already close to the world's first-class production level, we will go further and further in the future!
