Description

Technical Field

[0001] The utility model belongs to the technical field of ore screening, and in particular relates to an anti-loss device for a linear vibrating screen. Background Art

[0002] The ore type in Panzhihua area is vanadium-titanium magnetite, and the titanium production process is spiral gravity separation process. The production principle is to use the gravity of the ore to autonomously separate ores of different grades, so as to achieve the goal of enrichment. Before the raw ore enters the titanium selection process, the ore grade of coarse-grained minerals is low, which will affect the quality of the final product, so a coarse separation process is required, that is, the coarse and fine ores are separated through screening equipment.

[0003] In actual mineral processing, we use a linear screening equipment, model LB36730, with a length of 7.3 meters, a width of 3.6 meters, a screen area of ​​26.28 square meters, an amplitude of 6-11mm, a power of 55KW, 44 screens, and a screen hole size of 1mm*1mm.

[0004] However, during the production and use process, due to the fast flow speed of the slurry, some fine-particle ore will be discharged with the tailings under the action of impact, so some ore will be lost. In order to reduce the loss of ore, an anti-loss baffle is added to the linear screening equipment, which can reduce the flow speed of the slurry and improve the screening accuracy of ore particles of different particle sizes. At the same time, it has an automatic cleaning function, which can maintain the stability of the screening effect and improve the screening efficiency. Utility Model Content
