hollow shaft/trunnion for cement mill
Product Information
The hollow shaft is an important part of the barrel rotary bearing ball mill. In the process, the contact and the ball mill sphericalbush neck and neck tube contact arc casting defects and voids may not have stomata; in the processing, and the spherical bearing contact part processing after grinding processing, ensure the precision and smoothness therefore, the casting process requirements are very high.
Our company can Professionally manufacture the mill and the hollow shaft of the ball mill. The powerful casting and forging, heat treatment,machining ability, strict quality, process control method and perfect detection and experimental means make the mill shaft with a high reputation and exported overseas.
Advantages:
1, high quality steel
2, large R fillet
3, high strength bolts and cylinder connection
4, molten steel refining furnace (blowing argon and R-H vacuum treatment)
5, using special sand, strictly control the pouring temperature and casting speed
6, bolster bearing processing, to ensure that the coaxial degree of end mouth and roughness
7, casting rough mechanical properties and chemical composition (internal control standard)
8, ultrasonic examination after rough machining
9, ultrasonic detection and magnetic particle inspection after finishing
