Extending the life of a ready-mix drum liner pays many dividends.

Kloos believes the liner installation will make the delamination problem virtually non-existent. “Producers will experience less labor repair time, lower production cost per cubic yard, and better customer service,” he says.

According to Bob Welker, sales and marketing manager for Argonics, the liner manufacturer that has unveiled this new system, the one-layer pour is just part of an innovative approach. The Marquette, Mich.-based company looked for a solution that not only extended liner wear life, but reduced liner pop-outs.

Along with the new pour process, Welker says that engineers studied the design of the liners' steel reinforcement. The new design features more reinforcing that allows for an increase in anchorage to the drum. Plant maintenance employees are able to leave the drum knowing that the liner's fit is tight. The new design also features a new key-lock mechanism that can help spread the stress generated from the material impact laterally into the liner, minimizing the hammering effect of loading.

There's another benefit from the new material: The liner is lighter in color. Welker says that plant operators in which the prototypes had been installed last winter report it's much easier to look inside the drum during inspections. The liner kits are available for most of the commonly found mixers, including Con-E-Co, Erie Strayer, Helco, Inventure, Rexcon, Ross and Vince Hagan.
