Screw was Manufactured and Delivered in 3 Days

A critical operation at the Calera plant involved conveying quicklime to a hydrator using a screw conveyor. Prior to a planned shutdown, the existing screw failed and could not be repaired. Downtime is valued at thousands of dollars per hour and the plant needed help. Without a replacement screw, hydrated lime could not be produced since there was no redundancy built into the system. The lime producer needed a special screw manufactured immediately and KWS responded by exceeding expectations.

External Collar and 3-Bolt Drilling Increase Torque Rating

With a commitment to continuous improvements, KWS has streamlined every manufacturing procedure and now, provides the shortest lead times in the industry. Lean manufacturing processes have reduced queue times, allowing for efficient production and improved deliveries. Standard lead time to build the new screw was fifteen working days, but our goal was to get the plant up and running as soon as possible.

After being notified of the screw failure on Wednesday afternoon, KWS manufactured and delivered the replacement screw within three days. The new KWS screw was installed and the plant was running at full production on Saturday morning. KWS reduced the lead time from fifteen to three working days and satisfied another valued Customer.

The replacement screw was very special in design with heavy-duty flights, 3-bolt shaft connections, and continuously welded flights on schedule 80 pipe. The drive end of the screw was reinforced with an external collar that fit on the pipe OD and reinforced the area around the coupling bolt holes.

Testimonial

"Turnaround time was great! We needed the screw much sooner for a shutdown. We called KWS and they moved up the delivery date to meet our needs. The screw was installed and running that Saturday. Thank you KWS!"
