Screen Machine Industries

Screen Machine is an innovative American manufacturer of portable machinery dedicated to material crushing, screening and stockpiling. Our product line provides solutions ranging from 15–600 tons per hour across a vast array of applications such as rock, sand, gravel, concrete, asphalt, topsoil and compost products.

Screen Machine products include heavy-duty track-mounted Jaw, Cone and Impact Crushers, Spyder, and Scalper screens, Trommels and Shredding Plants. Portable Stacking Conveyors complete the product line in a variety of sizes. Collectively, they can Crush Any Job™.

All Screen Machine products are built at our factory in Etna, Ohio, just east of Columbus. We are committed to making the best equipment in the industry, and providing the expertise to help maximize your productivity with it. Here are a few other key elements that complete the Screen Machine difference:

  • The most durable, USA-made Grade 80 steel is the foundation of many key components on our machines. Our competitors do no use Grade 80 steel. And every machine is backed by American quality, craftsmanship and patented innovation.
  • Screen Machine partners with brand names like Caterpillar®, Dodge® and Precision® on our products, adding integrity and reliability to the entire line.
  • Our dealer and customer support is the best in the business. We support what we sell for the life of the product.



IROCK is an American manufacturer with more than 20 years of experience in crushing and screening. Value is more than just the purchase price. It’s the total cost of ownership, including maintenance operation costs and resale values. IROCK equipment will maximize your operational efficiency.

IROCK equipment takes a beating hour after hour and day after day. That’s why we use the highest quality components available, like Caterpillar® engines, PT Tech clutches, oversized shafts and bearings. We also implement unique design elements, like our exclusive ROCK BOX, to reduce wear and provide our customers with reliability year after year.


Thompson Tractor has what it takes to put you in the right machine for your job. For more information on Crushing and Screening products, please contact Jim Bailey or your heavy equipment sales representative.
