Frequently Asked Questions
What is a vibrating screen?
Vibrating screens sort materials by size using vibratory action. Smaller material falls through the screen mesh/fingers, separating oversize material from fines.
How does a GK vibrating screen work?
General Kinematics’ vibrating screens use a Two-Mass vibratory design in which an exciter mass, or drive, mobilizes a secondary trough body mass. Two-Mass creates a responsive sub-resonant system that handles material load surges without reducing screening efficiency or overall throughput.
By eliminating high-wear components like drive belts, oversized motors, and heavy bearings, Two-Mass equipment significantly lowers operating costs and reduces ongoing maintenance requirements.
In screening operations, a feeder, primary crusher, or conveyor feeds material to the screen. Then, the screen vibrates, activating and moving the material over the screen deck—usually a finger deck or mesh screen. Some screens, such as the aggregate screen, feature multiple levels for finer processing.
Although GK is known for two-mass screening, GK employs world-class experts in all kinds of vibratory and rotary screening. We know one size does not fit all in screening applications, and in some cases, direct-drive or even non-vibratory screens are the best fit. GK offers both options and works with customers to find the best fit.
How Do You Prevent Screen Blinding and Pegging?
Screen blinding and pegging reduce the open screening area and can reduce screening efficiency or even cause costly downtime if they build up. Well-designed screens are built for their specific application, provide consistent feed rates, offer good material retention, and use screen media or decks designed to handle the material you’re processing.
For example, in recycling operations, the GK finger deck uses a tapered finger design with unique cam-out surfaces and staggered positions to help prevent material bypass and plugging, trapping, and pegging.
How to size a vibrating screen?
- Material Condition: How wet/sticky is the material? What condition is it in when it’s screened? Does it include trapping hazards like pokers?
- Capacity: Volume of material, tons per hour (tph) processed
- Over/Half Size Material: How much material should go over the deck vs what percentage of material should be passing through screen openings.
- Weight: Material density
GK’s on-site lab can help determine the right screen sizing for you. Schedule an appointment for on-site testing to get started.
How many types of vibrating screens are there?
GK offers a wide variety of vibratory screening equipment, each designed for a specific application.
- Horizontal: Horizontal screens classify finer aggregate materials with high precision and accuracy.
- Incline: Incline screens use gravity to process aggregate materials, allowing them to process more material than horizontal aggregate screens.
- FINGER-SCREEN™ Family: Designed for even the most difficult recycling applications, GK’s finger decks effectively handle high-impact materials, reducing jamming and ensuring continuous, efficient operation.
- Grizzly Screens: Separate larger rocks and boulders from smaller ones, protecting downstream crushing equipment.
- Trommel/Rotary Screens: A non-vibratory option, rotating cylindrical screens and trommels that separate material by particle size. Particularly useful for compost, hemp, and topsoil applications.
- DE-STONER® Air Classifier: Though not a conventional screen, GK density separators separate and classify differing materials using a combination of air and vibration.
- Rod Deck Screens: Use reduced surface area to better screen wet and sticky materials than other vibratory screens, preventing sticking and blinding.
- Dewatering Screens: Remove excess water and moisture from materials for further processing. Especially useful in aggregate and mining applications.
- Direct Drive Screens: Feature fewer moving parts and are a more cost-effective option for smaller or more budget-conscious operations.
For aggregate and mining applications, GK offers single-deck, double-deck, and multi-deck configurations to achieve precise particle-size distributions.
