The 30-year plant is becoming a thing of the past.

According to McLanahan Corp.’s Mark Krause, producers want flexibility in their equipment. Some may only require a crusher or screen for three to five years, while others seek opportunities to utilize existing equipment in different areas of their business.

With this concept in mind, McLanahan launched a triple-shaft horizontal screen at the 2019 AGG1 Aggregates Academy & Expo that provides producers with this sought-after flexibility.

“That’s why we came out with the H-Series (MAX) horizontal screen,” says Krause, managing director of North America at McLanahan, during a press conference at the trade show in Indianapolis. “It’s got a lot of flexibility in it. It could be a scalp screen, finish screen, wet screen, dry screen, portable, static – it can be all of those different things.”

According to McLanahan, the new H-Series MAX screen provides high G-forces to vibrate and move material down the length of the screen. A primary feature is the screen’s aggressive action in applications where blinding or plugging of the screen media openings can occur.

Additionally, the H-Series MAX features fully adjustable oval stroke technology to create advantages that will impact profitability, McLanahan says.

Other features of the screen are weld-free, high-strength steel side plates that are laminated in all high-stress areas. These are coupled with reinforced deck frames that combine to create a screen basket assembly with significant strength and durability.

Reinforcing straps provide added side plate strength for side tensioning media, and the drive guard and snubbers are strategically designed and located for improved access to tension bolts, the company says.

“It has a patent-pending feature on it to help keep the bearings lubricated on it all the times,” says Cory Jenson, executive vice president of sales and business development at McLanahan, of the screen.
