Description

Technical Field

[0001] This utility model relates to the field of limestone processing technology, and in particular to a vibrating screen suitable for limestone processing. Background Technology

[0002] In limestone processing, vibrating screens are key screening equipment, directly affecting the particle size uniformity and production efficiency of the finished limestone product. However, vibrating screens currently on the market have many problems in practical applications, making it difficult to meet the high-quality requirements of limestone processing.

[0003] Regarding the screening effect, most existing vibrating screens adopt a single vibration mode with limited range of vibration intensity and frequency adjustment, which cannot effectively cope with the uneven particle size and high impurity content of limestone. Moreover, due to the lack of effective buffer and shock absorption design, the impact force generated during vibration is easily transmitted to the equipment foundation, which not only shortens the service life of the equipment but also causes significant noise pollution.

[0004] In the feeding stage, most vibrating screens adopt a centralized feeding method, causing material to accumulate in localized areas of the screen surface and failing to spread quickly and evenly across the entire surface. This reduces the utilization rate of the screen surface, results in inconsistent residence time of the material on the screen surface, and causes some material to pass directly through the screen without being fully screened, severely impacting screening efficiency.
