The circular vibrating screen (also known as the stone material screen) is an efficient screening equipment that utilizes the directional rotating excitation force to cause the screen surface to vibrate in an approximately circular trajectory. It is specifically designed for multi-stage screening of medium and fine-grained materials and is the core classification equipment in sand and gravel production lines, mining plants, and various raw material processing processes. Through the configuration of multiple layers of screen nets, this equipment can achieve precise classification of materials on a single machine, producing various specifications of finished products. It features high screening efficiency, large processing capacity, and reliable operation.
Product features
Powerful and efficient vibration system
It adopts a cylindrical eccentric shaft vibration generator, which provides strong and concentrated vibration force. By adjusting the counterweight of the eccentric block, the amplitude can be adjusted continuously and precisely, enabling it to easily adapt to different material characteristics (such as specific gravity, humidity, and particle size) and screening process requirements, achieving the optimal screening effect.
Outstanding screening performance
Optimized motion trajectory: The circular vibration causes the materials to constantly be thrown up, rolled, and move forward in a spiral motion on the screen surface. The screen flow line is long, the probability of material passing through the screen is high, the screening is thorough, and the efficiency is significant.
Multi-layer classification, one machine multiple uses: It provides various screen mesh configurations ranging from single layer to four layers, and can simultaneously classify the materials into 2-5 different specifications. The screening specifications are diverse, simplifying the process flow and saving equipment and site investment.
Sturdy and stable structural design
The screen box is made by welding heavy steel beams and plates, with a sturdy and stable structure that can withstand the impact and continuous vibration load of large pieces of materials.
The main shaft of the vibration generator is made of high-strength alloy steel, and the bearings use large-clearance heavy-duty special bearings to ensure long-term reliable operation under strong vibration force.
Durable and reliable, with low maintenance costs
Key components such as the screen frame and the vibration generator have a long design life. The screen mesh can be selected from various high-maintenance materials (such as manganese steel, polyurethane), and the service life is long. The equipment operates with low vibration noise, has a small impact on the foundation's dynamic load, and has a friendly working environment.
The modular design enables easy maintenance and quick replacement of components such as the vibration generator and screen mesh, minimizing downtime.
