The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Oval stroke horizontal screens deliver high productivity and efficiency in a low-profile package.
The low screen height allows for operation in height-restricted areas and for maximum portability. The triple-shaft design employs an oval motion stroke pattern that generates an aggressive screening action, reducing plugging and blinding while providing extended bearing life. Multiple configurations are available for a wide range of applications, from fine screening to heavy scalping.
Applications
Aggregates
There are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes. 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 is one of the most recycled materials in the world and 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 projects today depend on an available supply of quality concrete mix. With the most comprehensive line of concrete production equipment in the industry, Astec is ready to help meet that demand.
Construction aggregate is typically medium or coarse materials like granite, limestone or trap rock, sand, gravel, slag or recycled concrete. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.
Construction and demolition recycling (C&D) is mixed material associated with construction and demolition. The material could include wood, cardboard, gypsum, plastic, metal, wire, roofing shingles, asphalt, concrete and more. By separating and recycling different materials it reduces landfill waste and associated costs, while also producing value-added products.
Crushed stone is a versatile product that can be used in a wide range of applications from construction to road building and even agriculture. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.
