ball mill Hollow shaft Brief Introduction and Application:
Hollow shaft is an important part of ball mill. Its function is bearing the rotary of ball mill shell. Technically, hollow shafts should not have below holes and sand holes on the neck of spherical tile and circular arc neck of shell connection. When producing, spherical tile needs grinding after part machining, to secure precision and smooth finish. This requires very high standard of casting technology.
ztic’s hollow shaft usually constructed from 4140,40Cr,45#,etc, of course customerized material accepted, after forging, rough machine, heat-treatment, finish machining process, shaft have good inner micro structure with excellet mechanical property and hardness, degree of roughness can be smooth to 0.8.
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.
Ball mill Hollow shaft 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
