Linear Vibrating Screen Machine for Mining, Sand and Minerals
A linear vibrating screen moves material in a straight line across the screen deck. It is used to grade granular material into sizes, to remove dust or fines, and to drain water. We build it to your material, capacity and cut size.

What is a linear vibrating screen?
It is a screen box on springs, driven by two vibration motors (or a pair of exciters) that turn in opposite directions. Their sideways forces cancel and the forward forces add up, so the box throws the material along one straight line. The material hops forward over the mesh: undersize falls through, oversize travels to the end and leaves as a separate product.
How does a linear vibrating screen work?
- Feed enters at one end and spreads across the width of the deck.
- The straight-line throw lifts the particles and moves them forward, so they meet the mesh many times.
- Particles smaller than the opening pass through to the lower deck or the undersize chute.
- Oversize leaves over the discharge end. With more than one deck you get more than two size products.
Because the motion itself conveys the material, the deck can sit level or at a small angle. That keeps the machine low and makes it suit dewatering and wet screening as well as dry grading.
Applications
- Grading sand, quartz and silica sand, feldspar and other granular minerals.
- Removing fines or dust from a product.
- Wet screening with spray water, and dewatering (see the dewatering screen).
- Screening ahead of magnetic separation, so the separator gets an even size range.
Linear vs circular vibrating screen
A linear screen throws material in a straight line and can work on a level deck; it suits finer granular material, multi-size grading and dewatering. A circular vibrating screen uses a single exciter and an inclined deck; it suits coarser crushed ore and stone at the crusher. If you are not sure, send your feed size and target products and we will recommend one.
How to choose a mining vibrating screen
- Material and particle size: what you screen, the top size of the feed and how much fine material it contains.
- Cut size (mesh / aperture): the size you want to separate at, and the number of products (one cut or several).
- Capacity: tonnes per hour of feed to the screen.
- Wet or dry: dry screening, wet screening with spray water, or dewatering.
- Screen media: woven wire mesh, polyurethane panels or perforated plate, chosen for wear and blinding.
- Site details: available space, feed and discharge points, and your local power supply.

Frequently asked questions
What is a linear vibrating screen used for?
Grading granular material into sizes, removing fines or dust, wet screening and dewatering in mining, sand and mineral lines.
What is the difference between a linear and a circular vibrating screen?
A linear screen moves material in a straight line using two counter-rotating motors and can run on a level deck. A circular screen uses one exciter and an inclined deck, and is usually chosen for coarser crushed ore and stone.
How many decks can a linear vibrating screen have?
One or more. The number of decks follows the number of size products you need; tell us your target sizes.
What does a linear vibrating screen cost?
It depends on deck size, number of decks, screen media, material of construction and motors. We do not publish prices; send your material, capacity and mesh size for a factory quotation by email.

Horizontal vibrating screen
A linear vibrating screen is often installed as a horizontal vibrating screen, or at a slight incline, for sizing and conveying crushed ore and sand.
