This Astec 8203-38CS is a used screener — sometimes referred to as a vibrating screen or screening plant — built in 2022 and currently located in Nevada, USA, priced at $175,000. Screeners are core pieces of quarry and aggregate processing equipment, used to separate crushed rock, gravel, sand, and similar bulk materials into sized fractions by passing them over vibrating mesh or wire cloth decks. Astec is a well-established American manufacturer of heavy equipment for the road-building, aggregate, and mining industries, producing a broad range of crushing, screening, and material handling machinery.
The vibrator mechanism is a right-hand-drive, oil-lubricated triple-shaft unit that produces an oval stroke pattern, with adjustable stroke settings and 190mm bearings. This configuration is designed to provide consistent, controllable material movement across the decks while accommodating the demands of heavy quarry-duty operation. Rubber springs are fitted to isolate vibration and protect the supporting structure.
The machine is equipped with single-crown decks featuring draw plates and fasteners for side-tension wire cloth, and there is 5 inches of extra clearance between the top and center decks — a useful feature when processing bulky or sticky material that might otherwise bridge or block in tighter configurations. The stringers extend into the feed box, providing additional structural support at the feed point where impact loads are highest.
A 24-inch integrated feed box is included, fitted with 1-inch square opening punch plate to pre-classify incoming material, and 6-inch AR-lined discharge lips to resist the abrasive wear generated by high-volume stone and gravel throughput. The deck panels incorporate spray hole knockouts and access holes with covers, allowing for optional wet screening or maintenance access as required. The drive system is a v-belt arrangement with an adjustable motor sheave and belt guard, and a motor mount is provided, giving operators flexibility in drive configuration and speed adjustment.
