Screens Equipment
Engineered for efficiency and high productivity, ASTEC designs and manufactures innovative screening equipment versatile in multiple aggregate applications. ASTEC screening options includes:
Incline Screens:
- Grizzly Scalping Screens: Utilizing the TL vibrator mechanism, both single- and dual-shaft models are available. Deep section grizzly bars allow up to 6″ nominal spacing without interference from cross members. ASTEC inclined grizzly scalping screens are reliable and low maintenance with proven performance.
- Valu-King Incline Screens: Designed for long service life, the vibrator mechanism incorporates spherical roller bearings and grease lubrication.
- Vibro-King TL Incline Screens: From heavy-duty scalping of coarse stone to fine sizing of finished products in wet or dry applications, the Vibro-King TL® series is feature-packed and built to deliver low-cost performance.
Horizontal Screens:
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: The horizontal screens product range includes:
- Oval stroke horizontal HS screens
- Oval stroke horizontal MS screens
- Oval stroke horizontal LP screens
- Oval stroke horizontal QF screens
High Frequency screens:
ASTEC high frequency screens utilize high-speed vibration, from 3600 – 4200 rpm, directly induced to the screen media, allowing for increased stratification and material separation.
Dewatering Screens:
These single-deck screens dewater fine aggregates prior to stockpiling. By utilizing a dewatering screen, producers can cut drying time significantly and get material out the door quickly.
Combo Screens:
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.
Portable Screen Plants:
Engineered for a variety of applications, our screening plants enable producers to succeed in a variety of markets including recycle, aggregate, mining, biomass and industrial materials. We offer a variety of portable screening options, including oval stroke horizontal, incline and high frequency screens.
Feeders Equipment
Material feed systems allow producers to maximize productivity and performance for efficient and profitable operations, product line include:
Apron Feeders:
These feeders feature a rugged, heavy-duty construction and are designed to handle feed sizes of up to 60” (1,500 mm) where no fines removal is required or where fines are removed by a separate vibrating grizzly.
Vibrating Grizzly Feeders:
Adjustable gear timing and bolt-on counterweights allow for maximum stroke adjustment (both angle and length) to achieve optimum feed control and consistent production.
Pan Feeders:
These feeders feature support springs with guards, bolt-in replaceable liners, re-greaseable bearings and exposed exciters for ease-of-access. Additional options include cone discharge spout, rubber liners and variable frequency drive.
