This paper briefly introduces the solution to the problem of blocking the screen of rotary vibrating screen

The new type of high-precision fine-grained screening equipment for the family members of the rotary vibrating screen factory can achieve satisfactory screening effect for both particles and fine powder Under the excitation of the vibrator, the screen body produces the compound rotation vibration, which forces the material to form the track vortex in the screen machine This kind of vortex is very useful for the screening of the material By adjusting the relative position of the upper and lower hammers, the moving track of the material on the screen surface can be improved, and the residence time of the material on the screen surface can be prolonged or shortened, so as to achieve the ideal screening effect The equipment has the advantages of compact structure, small volume, no dust, low noise, high output and convenient mobile maintenance Widely used in medicine, food, chemical and other industries The following is a brief introduction of how to solve the problem of blocking the screen of rotary vibrating screen, as follows: blocking cause: during normal operation of rotary vibrating screen, due to various characteristics of materials, different shapes will produce various forms of screen plugging The main reasons for blocking are as follows: 1 Spherical particles or materials with multiple contact points to the mesh; 2 High moisture content of materials; 3 A large number of particles close to the separation point; 4 Static electricity will occur; 5 Thick woven mesh; 6 Many flake particles 7 The material has fibrous material; 8 The thick screen, such as rubber screen, has unreasonable hole shape design, which does not reach the upper, lower and larger size, so that the particles are stuck Because most of the particles need to be screened are irregular, so there are many reasons for blocking Solutions: in order to effectively prevent the screen blocking of vibrating screen, measures should be taken for the above reasons: 1 For materials with more flake particles, it is necessary to change the material crushing mode and the particle size matching of different crushing processes 2 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 blocking the screen 3 When the moisture content in the material is more than 5%, if the material is dried unconditionally, the sieve surface and sieve hole shall be selected accordingly 4 When the moisture content is more than 8%, wet screening shall be adopted Reasonable adjustment of mesh tension is an effective method to reduce mesh plugging Reasonable tension causes slight secondary vibration between the mesh and the support beam, so as to effectively reduce the occurrence of hole plugging The specific method is to make the tension hook into a constant tension mechanism, that is, to install a spring on the tension bolt.
