In 2009 Valley Rubber purchased Rockland International, an engineering company that specialized in guaranteed solutions for some of the toughest problems found in the Mining, Aggregate and Cement industries, such as noise, dust, spillage, sticky material buildup, abrasion and more. That rich legacy continues today with our Rockland Engineered Solutions. This trusted brand is synonymous with providing the best answers to your toughest problems.
Our engineering team and support staff is larger and more capable than ever and you now have a direct association with the manufacturer of the components within the solution. Combining the solid manufacturing capabilities of Valley Rubber with the proven Rockland Engineered brand provides you with a start-to-finish partner for projects that include field reconnaissance, engineering and manufacturing.
We believe in a collaborative effort with a spirit of cooperation. When these two come together, we can work with you to accomplish amazing things. No two solutions are the same just as no two sites are the same. Our solutions are custom designed for you. Simply put – there are too many variables in each application to merely white out one company’s name on a title block and replace it with yours. Working together we will offer a Credible Custom Solution.

Before & After
Before: Chute backs up as material sticks & After: Inflatable liners keep the chute clear & functional.
Plugged chutes are a problem of the past with Valley Rubber designed inflatable liners.
Improved designs reduce power consumption, carbon footprint & maintenance providing positive ROI.
Before: Almost completely blinded & After: Virtually no blinding with Valley Rubber designed screens.
Before: Major buildup & After: Inflatable liners solve the buildup problem.
Before: 24 hours run time & After: 5 weeks run time.
Properly fitted double-lip conveyor dust seals, skirting & canoe liners minimize dust & fines.
Before: Welding required weekly & After: 7 year life on many liners; noise levels dropped dramatically.
Before: Bent floor due to impact & After: Grizzly bars handling 1,200 TPH of minus 5 foot shot rock.
Before: 118 Db & After: 92 Db = 800% reduction in noise levels.
TROMMEL SCREEN PEGGING
Before: Constant maintenance & After: Our screens maximized cost-per-ton targets.
Before: Unnecessary man-hours & After: Increased productivity & improved safety with rubber screens.
Before: Spillage creates dust & unnecessary man-hours & After: Redesigned hopper eliminates spillage.
Spillage, dust & the man-hours to control it all are essentially eliminated with the new chute design.
STICKY MATERIAL BUILDUP
Specially formulated anti-stick rubber is used on grizzly bars to prevent material buildup.
Before: 2″ steel plates wear out in 90 days at best & After: Rubber/ceramic liners going strong after 3 years.
