Vibrating Screens

Vibrating screens are essential equipment for material classification in crushing and screening plants, directly impacting final product quality and plant efficiency. They are designed to precisely separate aggregates, minerals, or industrial raw materials, whether from crushers or in their natural state, into the desired size fractions. At STS Global Machinery, we manufacture durable and efficient vibrating screens that deliver high performance and long life, even under the most challenging conditions.

Working Principle: Precise Separation by Controlled Vibration

The operating principle of vibrating screens is based on separating the material according to its size by moving it in a controlled manner on the screen surface:

• A drive mechanism (vibro motor or shaft system) with eccentric weights mounted on the screen body creates a circular or elliptical vibration movement.
• This vibration gives the material on the screen surface both a forward movement and a bouncing motion that allows it to be stratified.
• As the material moves across the screen surface, grains smaller than the mesh aperture of the screen wire fall to the bottom floor or the relevant product chutes.
• Larger particles remain on the sieve surface and move towards the end of the sieve and are directed to the next process or stock area.
• Factors such as the screen inclination angle, vibration amplitude (stroke), speed, and screen mesh type directly affect screening efficiency and capacity. These parameters are precisely adjusted according to the type of material to be processed and the desired product properties.

Key Features and Benefits

• Durable and Sturdy Structure: Using bolted construction instead of a welded body increases resistance to metal fatigue and provides a longer-lasting structure.
• High Screening Efficiency: Thanks to its optimized vibration characteristics and wide sieving surface, it ensures fast and precise separation of materials.
• Flexible Configuration: It can be produced in 2, 3 or 4 layers depending on project needs, which allows multiple final products to be obtained with a single machine.
• Easy Maintenance: Easy replacement of screen wires and easy access to maintenance points minimize downtime.
• User-Friendly Design: Standard features such as front chutes that direct the material flow and a wear-preventing stone box (feeder box) ensure smooth and efficient operation.
