Screw rolling steel balls production line
Brief Introduction
Dia25mm – 40mm screw rolling steel grinding balls production line is used to produce steel balls 25mm, 30mm, 35mm and 40mm with different composition. The surface hardness of the produced balls can achieve over 60 degrees. Widely used in mines, power station and construction industry. Produced steel balls has no de-shaped, no chamfer, and good quality.
The rotary cutting steel ball start at ’50-’60s, our country imported from Russia equipment and technology. In the 1970s, the whole spinning steel ball process was eliminated, mainly because the raw materials of steel-making technology could not meet the requirements of wear resistance and heat treatment process.
After 2000, the research and development of the raw materials and heat treatment of the rotary cutting process began in China. The rotary cutting process has the advantages of high productivity & high comprehensive benefit of wear comparability and so on.
Main Components of the steel balls production line
- Induction furnace for steel bars heating
- Feeder
- Screw rolling machine
- Rollers and guide plates
- Gear box
- Universal joints
- Reducer with motor
- Roller box
- Quenching system
- Cylinder
- Electrical control panel
- Closed type cooling tower
- Open type cooling tower
Producing process
First put the round steel bars on the feeding supporter and then the induction furnace heats the round steel bars in the certain temperature. Afterwards, screwing the balls continuously. The formed steel balls go into the water quenching unit to quench for some time. Then the balls go to the temperature preserving box. Until now, the whole producing process is finished.
Advantages of Screw Rolling Steel Balls Production Line
High Production Efficiency
The continuous rolling process allows large-scale manufacturing of forged grinding balls.
Compared with manual or batch production methods, the production line provides higher output and stable operation.
Excellent Grinding Ball Quality
The rolling process creates a dense internal structure, improving:
- Impact resistance
- Wear resistance
- Working life
Consistent Ball Size
The automatic rolling system helps maintain uniform grinding ball dimensions.
Consistent size improves grinding performance in ball mills.
Lower Material Waste
The screw rolling process uses steel bars efficiently and reduces material loss during production.
Automated Production
The complete production line can integrate:
- Heating furnace
- Rolling machine
- Heat treatment system
- Inspection equipment
to achieve continuous operation.
Screw Rolling vs Casting Grinding Ball Production
