Description

Technical Field

[0001] The utility model relates to the technical field of grading screens, in particular to a rotary grading screen with a focus on balance. Background Art

[0002] A weighted, balanced rotary grading screen is a device specifically designed for screening materials. Its "weighted balance" means that one side of the screen frame is slightly heavier than the other during operation, maintaining stability and reducing vibration and noise. "Rotary grading" means that the device rotates to evenly move material across the screen, gradually separating it into different particle sizes. This device can efficiently screen a wide range of materials and is suitable for a variety of industries, including ores, chemical raw materials, and food, helping to improve production efficiency and ensure screening quality.

[0003] In existing screening technologies, the screening effect and efficiency are often low, especially when processing complex or large-particle materials. Since the equipment cannot perform sufficient shaking screening, the material is difficult to be evenly distributed on the screen surface, resulting in accumulation and blockage of some materials. This accumulation not only hinders the smooth passage of materials, but also makes it difficult for smaller particles to fully fall to the lower screen, thereby reducing the screening accuracy. At the same time, larger particle materials are not separated in time, further affecting the overall screening effect. These problems lead to inaccurate material classification in the production process, reduced product quality, and due to low screening efficiency, the processing capacity of the equipment is limited, which ultimately affects the operating efficiency of the entire production line and increases operating costs. Utility Model Content
