Combo Screens

Overview

This truly unique innovation combines the best characteristics of both incline and horizontal screens and has proven to deliver unsurpassed productivity, efficiency and flexibility in wet or dry applications. 

The triple-shaft design employs an oval motion stroke pattern that generates a more aggressive screening action, reducing plugging and blinding while providing extended bearing life. 

Applications

  • Sand & Gravel

    Sand and gravel are aggregates that are gathered from naturally occurring deposits. These aggregates, when gathered, may contain clays, silts and other deleterious material that needs to be processed out for commercial-grade products. Reduction and sizing can be accomplished with a variety of crushers and screens. Once the material is accurately processed, it can be used for road building, construction materials and a variety of other applications.

    • Aggregates

      There are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes of aggregates. Processing these materials typically requires various steps including reduction and sizing and also may include dewatering and sorting. Producers can use a variety of crushing, screening, dewatering and conveying equipment to meet their desired specifications.

      • Concrete Recycling

        Concrete is one of the most recycled materials in the world that can be repurposed several times over. Once the existing concrete is demolished or torn up, it needs to be processed for accurate shaping and sizing using a crusher and screen.

          • Construction and Demolition (C&D) Recycling

            Construction & Demolition Recycling (C&D) is mixed material associated with construction and demolition. The material could include wood, cardboard, plastic, metal, wire, roofing shingles, concrete and more. By separating and recycling different materials it reduces landfill use and tipping fees, while also producing value-added products.
