CASTING INNOVATIONS


New Rotary Drum Cast Liners Having severely worn and


damaged rotary drum cast liners, Rochester Metal Products (Roch- ester, Indiana) began a search to find replacement liners. With a capacity of 7TPH castings and 30TPH sand, the foundry was looking for a liner system that could withstand their rigorous pro- cessing requirements. Rochester Metal Products pours


gray and ductile iron and has a melt capacity of 80,000 tons per year. It serves many industries, including but not limited to the agriculture, auto- motive and heavy truck sectors. General Kinematics (Crystal


Lake, Illinois) proposed the LOCK- TITE rotary liner system. Te modular, bolt-together design of this liner system does not require GK installation staff to install, although GK supervision is recommended for the first installation. General Kinematics LOCK-


TITE rotary drum liners are con- structed out of abrasion resistant 450 Brinell steel, which is almost double the hardness (Bhn) of austempered


Liner cartridges arrive ready to slide into the drum shell.


ductile steel. Tis difference signifi- cantly increases wear resistance and liner component life. After weighing factors, Rochester


Metal Products selected the LOCK- TITE liner system. Installation of the LOCK-TITE liner system oc- curred over a holiday weekend.


Te installer found GK’s rotary liners to be quick and safe to install. “Rochester Metals is highly


satisfied with the installation and looking forward to many years of trouble-free service from their new liner system,” GK said in a news release.
