Challenge

Having severely worn and damaged rotary drum cast liners, Rochester Metal Products began a search to find the market’s best value on replacement liners. With a capacity of 7TPH castings and 30TPH sand, the foundry was looking for a liner system that could better withstand their rigorous processing requirements.

Approach

GK Engineers proposed the LOCK-TITE™ Rotary Liner System. The modular, bolt-together design of this liner system does not require GK installation staff to install, although GK supervision is recommended for your team’s first installation. Shipped in preassembled cartridges, the liners are safer to install than the competitions’ cast grid systems. General Kinematics LOCK-TITE™ Rotary Drum Liners are constructed out of abrasion resistant 450 Brinell steel, which is almost double the hardness (Bhn) of austempered ductile steel. ***See update below. This difference significantly increases wear resistance and liner component life.

Solution

After weighing key factors, including installation, durability, and affordability, Rochester Metal Products selected the LOCK-TITE™ Liner System. The ease of installation of the LOCK-TITE™ Liner System allowed for a successful installation over a holiday weekend.

Results

The installer found GK’s rotary liners to be quicker and safer 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.

***Update: General Kinematics LOCK-TITE™ Rotary Drum Liners are constructed using abrasion resistant 450 Brinell steel, which is significantly greater (Bhn) than typical ductile iron castings.
Furthermore, an additional abrasion resistant liner was installed beneath the main LOCK-TITE™ sections, to protect the drum shell surface in the flighted return zones.
