How GK Is Revolutionizing Rotary Drum Technology

Issued at 2016-05-27



From simple screeners to complex no-bake shakeout systems, GK is the world leading provider of shakeout technology to the global metal casting industry. While General Kinematics specializes in the use of vibratory technology for a majority of our shakeout solutions, we still had one shakeout technology that we did not offer. GK’s foundry team recognized a need in the marketplace for a more durable, safer, and easily maintainable rotary solution. General Kinematics' strategic goal of becoming the most complete supplier of world-class rotary foundry technology takes another step forward with DUCTA-SERIES™ line of rotary drums.


GK ROTARY SYSTEM

Why GK Rotary?

Drum Longevity: General Kinematics’ Rotary Drums allow for all wear surfaces to be replaced separately. Thus, you do not have to replace the unit when items wear down, just replace that specific part. 

It’s All about the Liners: General Kinematics’ patented LOCK-TITE™ Liner System (Musschoot and Massman) is designed to replace existing cast grid liner systems. Replacement options include liner panels, internal skin liners, or a complete replacement rotary drum body assembly which will line up with the existing drive machinery. GK works with you to find the right solution to improve your process.

Installation Process: Easy to install, this liner system does not require GK installation staff to install, although GK supervision is recommended for your teams’ first installation. Installation requires only two people, a welder, a come-along and miscellaneous hand tools.

Liner Construction: General Kinematics LOCK-TITE™ rotary drum liners, rifling, and clamp bars are constructed out of abrasion resistant 450 Brinell steel, which is almost double the hardness (Bhn) of austempered ductile steel. This difference significantly increases wear resistance and liner component life. 90° panel segments make installation much easier and allow for faster rotary drum liner installation and replacement. Also, the liner material is weldable, formable and repairable, enabling you to tune your process precisely through changes in rifling, hole opening sizes, etc. Should a section show abnormal wear, minor repairs or maintenance can be performed using steel plates and a welder; something that cannot be done with a cast grid system. When the time does come to replace GK’s LOCK-TITE™ liners, simply unbolt the sections that are worn and replace them with new panels. No other liner panels should be affected during a single liner panel replacement.


INSIDE DRUM

Superior Design: Simply stated, the unique design of LOCK-TITE™ Liner Systems inherently reduces your maintenance costs. GK developed this system by listening to our customers’ concerns about other liner systems on the market. Each segment is positively retained to the next segment using clamp bars, eliminating the need to remove previous rows of liners to access segments located internal to the drum. Secondly, clamp bars maintain mechanical hold between liner segments, preventing any loosening of panels. Thirdly, for localized wear areas, patch plates are easy to locate and can be welded directly to the liner, something you can't do easily with other liner systems. Additionally, since you can weld to the liners, maintenance staff can safely and correctly brace liners during service and installation without welding through rods to the skin. This saves significant time and makes for a safer and more comfortable work environment. Finally, there is no need for a compression ring, eliminating the frequent re-torquing sequences required with competitive liner installations.
