Description

TECHNICAL FIELD

[0001] The utility model relates to mine machinery technical field especially is related to a through and block formula vibrating screen screen cloth. BACKGROUND

[0002] The mine machinery vibrating screen screen cloth is a kind of wear-resistant, durable screening equipment component specially designed for mining industry, used for grading and screening the mined ore. This kind of screen cloth needs to withstand large impact force and wear, so high-strength steel wire is usually woven or welded to ensure its stability and long life in harsh working environment.

[0003] In the use process of the screen cloth, especially in the case of long-time continuous screening of processed materials, the gradual accumulation of material particles on the screen cloth is a common problem. This accumulation not only causes large particles to be directly stuck in the screen holes, but also causes fine particles and wet or sticky materials to adhere to the surface of the screen cloth, forming a layer of residue. With the passage of time, this layer of residue gradually thickens, further hindering the passage of materials, eventually causing the screen cloth to be blocked. As the amount of adhering material increases, the effective area of the screen holes decreases, making more materials unable to pass smoothly, thereby reducing the processing capacity per unit time. The material adhering to the screen cloth affects the consistency and accuracy of screening, which may cause the particle size distribution of the screened product to be uneven and not meet the quality standards. The material adhering to the screen cloth affects the consistency and accuracy of screening, which may cause the particle size distribution of the screened product to be uneven and not meet the quality standards, which is inconvenient to use.
