The Gyratory Screen is an independent production screening machine used for separating dry materials according to particle size. It is equipped with a positive screen cleaning system. The planar Gyratory Screen is a highly efficient screening device widely applied in industries such as mining, metallurgy, coal, building materials, power, and chemical engineering.
Working Principle
The planar Gyratory Screen is driven by a vibrating motor. The screen box performs planar rotary motion supported by springs. Materials enter the screen box from the feed inlet. Under the action of the planar rotary force on the screen surface, the materials move towards the discharge outlet. During the movement, materials smaller than the screen hole size pass through the screen mesh and become undersize products, while materials larger than the screen hole size remain on the screen surface and become oversize products, thus realizing the screening of materials.
Structural Features
- Screen Surface Structure: A multi-layer screen mesh structure is usually adopted. Different numbers of screen mesh layers and screen hole sizes can be selected according to different screening requirements to achieve precise classification of materials.
- Drive Device: Generally, a vibrating motor is used as the drive source, which has the advantages of strong exciting force, low energy consumption, and stable operation. By adjusting the angle of the eccentric block and the rotational speed of the vibrating motor, the amplitude and frequency of the screen box can be adjusted to meet the screening requirements of different materials.
- Support Device: Springs are used to support the screen box, which can effectively transmit vibrations and play a damping role, reducing the impact of the equipment on the foundation and lowering noise and energy consumption. At the same time, the stiffness and damping of the springs can be adjusted according to the actual situation to optimize the motion characteristics of the screen box.
Performance Advantages
- High Screening Efficiency: The planar rotary motion makes the motion trajectory of materials on the screen surface complex and uniform, enabling full contact with the screen mesh and improving the screening efficiency, which can generally reach over 80% – 90%.
- Large Processing Capacity: Due to the adjustable amplitude and frequency of the screen box, it can adapt to materials of different properties and particle sizes, has a strong processing capacity, and can meet the needs of large-scale production.
- High Classification Precision: The multi-layer screen mesh structure and precise control of motion parameters enable the planar Gyratory Screen to achieve fine classification of materials, and the classification precision can reach within ±0.5mm.
- Stable and Reliable Operation: The vibrating motor drive and spring support structure are simple, easy to maintain, the equipment operates stably and reliably, has a low failure rate, and a long service life.
Application Scenarios
- Mining Industry: It is used for the classification and screening of ores, such as the roughing and concentration processes of iron ores, copper ores, gold ores, etc., separating ores of different particle sizes to provide suitable raw materials for subsequent processes such as crushing and grinding.
- Coal Industry: It screens coal, classifies coal according to different particle size grades to meet the needs of different users, and also helps to improve the combustion efficiency and utilization value of coal.
- Building Materials Industry: In the production of sand and gravel, it screens the crushed stones to produce construction sands and stones of different specifications to meet the needs of projects such as concrete and asphalt pavements.
- Chemical Industry: It is used for the screening of chemical raw materials and products, such as the classification of plastic particles, fertilizers, pigments, etc., to ensure the quality and performance of products.
