Cause analysis and solution of screen plugging of linear vibrating screen

The reason analysis and solution to the blocking of the linear vibrating screen mesh: as an important equipment in coal preparation, mineral processing, building materials, electric power and chemical industry, the linear vibrating screen often has various failures in daily use, affecting the use Today's editor summed up the reasons and gave solutions for the blockages in the linear vibrating screen When the linear vibrating screen is in normal operation, due to various characteristics of materials, different shapes will produce various forms of blockages The main reasons for the blocking of the linear vibrating screen are as follows: 1 There are a lot of particles close to the separation point; 2 The water content of the material is high; 3 Spherical particles or materials with multiple contact points to the screen hole; 4 Static electricity will occur; 5 The material has fibrous materials; 6 There are many flake particles; 7 The woven screen wire is thick; 8 For the thick screen such as rubber screen, the hole shape design is unreasonable, which does not reach the upper small and the lower large, so that the particles are stuck Because most of the particles need to be screened are irregular, so there are many reasons for blocking In order to effectively prevent the clogging of the linear vibrating screen, measures should be taken for the above reasons: 1 When the particle size of the material is finer, the content of mud is more, and the screening particle size is smaller, the water content plays a decisive role in the clogging of the screen 2 When the moisture content in the material is more than 5%, if the material is dried unconditionally, the screen surface and screen hole of the linear vibrating screen shall be selected accordingly 3 When the moisture content is more than 8%, wet screening shall be adopted 4 For materials with more flake particles, it is necessary to change the material crushing mode and the particle size matching of different crushing processes It is an effective method to reduce the blocking of the screen mesh by adjusting the tension force of the screen mesh reasonably The reasonable tension force causes slight secondary vibration between the screen mesh and the support beam of the screen mesh, so as to effectively reduce the blocking of the hole The specific method is to make the tension hook as a constant tension mechanism, that is, to install a spring on the tension bolt.
