In a ball screw, balls travel through the nut, screw, and grooves when either the screw or nut rotates to produce continuous movement. The balls are routed into the nut's ball return system and travel in a continuous path, moving from the starting point to the end and back again.

To optimize your screw for your application, consider adjustments to the overflow s, rising current classifier, slurry feed and screw speed to retain product-sized fines. To recover fines lost to waste, consider adding a Separator™ to process the overflow, or consider feeding the screw with a Separator™ to improve efficiency.

However, the screw is hollow with a small hole in the head, so that when it's loosened, fluid and air make their way in through the screw, exiting the top. Because air naturally rises to the top of the fluid in the caliper (or is forced there via compression), loosening the screw first purges the system of air, followed by fluid. The Purge
