1, mesh with linear-shaped fracture Screen with linear-shaped fracture, usually due to screen no tension (not tight or pull) the state shall support the formation of the sieve box and the screen twice between the vibration caused by impact with each other straight-shaped mesh have broken the rules, causing some of this damage may be:
A, screen size is too long, causing tension screws loose sheets;
B, screen machine problems tensioner, tensioning plate and screen machine is not complete, tension plate (hook) thinning or deformation;
C, screen shape and size of bending and tension side plates are not complete;
D, sieve sieve welding fault cause structural damage;
E, rubber mat free when worn or article;
F, sieve or a sieve structure of defects in the design of machines;
G, screen box support section below the screen, which has some support articles and mesh spacing;
H, vibrating screen machines around spring stiffness uneven;
I, the amplitude of vibrating screen machine and too big.
2, wire mesh spread of irregular fracture occurred (wire no wear)
General, screen the entire screen surface of irregular fracture, fracture cross section of the grain under the circumstances to determine whether the material quality. However, the quality of stainless steel mesh over the guarantee period, except material (stainless steel mesh material quality guarantee period of one year, such as over this period may fracture)
3, severe wear mesh local Bumper and body damage to materials diversion.
4, mesh plug hole Screening, depending on the nature of materials, will produce various forms of mesh plug. Mesh plug the main reasons are the following:
(1) contains a large number of particles close to the separation point;
(2) higher water content materials; (3) spherical particles, or have more contact points on the mesh material;
(4) static electricity will occur; (5) material has a fiber material;
(6) particles is more; (7) weaving through the thick wire mesh;
(8) such as thick rubber mesh sieve, pore shape design unreasonable, does not meet under the big, small, Er Shi particles stuck.
Because of the need screening material particles are mostly irregular and, therefore, is to plug a wide variety of reasons. To effectively prevent the mesh plug, should be reason for these measures to plug the sieve. When the material finer, more clay content, and the screening size is small, the water on the screen of the block on the play a decisive role. When the material is greater than 5% of water, drying the material if the unconditional, should sieve, sieve to make specific choices. When the water is greater than 8%, should be used wet sieving. More particles on the sheet of material, you need to change the crushing method and size of different processes with a broken manner. Reasonable adjustment is to reduce the tension screen mesh is an effective method of plugging holes, reasonable tension to produce a small screen with the support of the secondary vibration of pyrene, thus effectively reducing the pore blocking phenomena, the specific approach is Constant tension to tension hook made, namely to install bolts in the tension spring.
