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.
Our mobile direct feed screens provide a rugged screening tool in a highly mobile configuration. These versatile screens can handle high volumes of material in both scalping and sizing applications.
Our direct-feed screens can be equipped with an array of screen media choices, including standard woven wire, punch plate, grizzly decks and finger decks. These screening plants are the perfect tool for overburden, scalping ahead of or behind a primary crusher, as well as screening an array of materials from aggregates to recycled materials to organics.
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.
