Phosphate fertilizer wire mesh is woven by stainless steel wire.The effective vibration difference is established by the secondary vibration of adjacent sieve bars in random vibration.Inorder to realize the continuous change of sieve hole in the process of sieving,there is relatively no fixed critical granular stone.The specific method is to set a sieve bar with relatively large vibration amplitude in two relatively static sieve bars,which can bounce or sieve the stone during the period of Kasser.
According to thespecial stone material,the relative elasticity and vibration amplitude of static and dynamic sieve bars, the phosphate fertilizer wire mesh and anti-blocking wire mesh can be adjusted accordingly,which can make the sieve mesh in the best screening state.The screening efficiency is increased by about 30%compared with the fixed-hole sieve mesh.The automatic cleaning function of the sieve net is basically realized,and the blockage of the sieve hole is greatly reduced.
The static sieve bars of phosphate fertilizer wire mesh and anti-blockage wire meshare thicker than those of dynamic sieve bars,which not only increases the wear resistance of the sieve,but also improves the screening efficiency.At the same time,the sieve structure of the sieve can minimize the contact point between stone and sieve hole and reduce the occurrence of blockage.
