CDE to unveil scrubbing, attrition system at Hillhead 2018

By |  May 25, 2018

CDE plans to showcase its new AggMax 163-SR scrubbing and attrition system at Hillhead 2018, June 26-28 in Buxton, England.

According to the company, the system is designed to incorporate a new RotoMax log washer and was specifically developed to supply the demand for a plant that bridges the gap between the company’s AggMax 80 and 250 models.

“The new RotoMax 163-SR is constructed and designed to the same high-duty standard as the RX250, with geometry refined for efficient scrubbing action at mid-range tonnages and variable speed drive as standard to optimize the retention time for the process material,” says Stewart Cusick, senior product development engineer.

With a new Infinity D1-63 pre-screen incorporated into the design, high-frequency screening action ensures maximum sand removal prior to the attrition process, CDE says. The new Infinity D1-43 screen dewaters organic and lightweight wastes liberated from the attrition process.

“An all-new Infinity H2-60 sizing screen efficiently separates material into three washed aggregates and allows the removal of sand liberated by the RotoMax’s attrition process,” Cusick says. “The aggressive throw on the horizonal washing screen ensures efficient screening by increasing retention time and allows generous access between the decks for maintenance access.”

The AggMax 163-SR, which features a modular design to allow upgrades to users’ plants, includes new modular GRP (glass reinforced plastic) walkways throughout the machine, providing safe working access to all maintenance areas of the plant. Access to the pump for easy maintenance has also been improved while a new tensioning mechanism was incorporated for quick and efficient set up of the pump, CDE adds.
