31 Various problems may arise due to the sifting of the selection process. The table below shows the typical causes and solutions. Trouble and solution of wire mesh breaks so as to tear the wire mesh. Wire mesh is worn and broken by abrasion The wire mesh is partially broken. (The same place is always broken) The wire mesh is broken so that the wire mesh is broken. There's a lot of clogging. I want to increase my processing capacity. I want to increase the efficiency of sievement. The wire mesh is mixed. ・Secondary vibration of the net can be considered. Regularly manage tension and tighten it. ・Check if the tension of the net is uniform. ・In the case of square-shaped sieves, check whether the intermediate net receiving rubber is worn. ・Increase the diameter of the line. ※Attention: Processing capacity may decrease due to lower opening rate. ・If the lower side of the net is worn, wear due to a tapping ball can be considered. Reduce the number of tapping balls or hit uniformly across the sieve net. Or consider setting up a protective net. ・If the processing material is concentrated, the input method is distributed. ・If the tapping ball is concentrated in a specific location, hit the entire sieve net uniformly. ・Check the processing materials and environment. In the environment where the net is corroded, the material is changed. ・Reduce the supply. ・The wire diameter is thinner and the opening rate is high. ※Attention: The strength of the wire mesh may decrease. ・Consider toncap and tierod wire mesh. ※Attention: The sifting accuracy may be worse. ・Consider measures to prevent clogging, such as tapping balls. ・In the case of sifting of highly viscosity, a fluoropolymer coating is considered. ・The wire diameter is thinner and the opening rate is high. ※Attention: The strength of the wire mesh may decrease. ・Consider toncap and tierod wire mesh. ※Attention: The sifting accuracy may be worse. ・Consider wire mesh for JIS Z8801 (test sieve) ・Consider flat top, archclamp wire mesh. ・Increase the wire diameter and consider the wire mesh with less misalignment. ・Increase the opening rate (beware of misalignment). ・Perform periodic inspections to detect wear and tear at an early stage. ・Consider magnetic materials such as KNM21 and Darmaloy, and remove them with magnets. ・Consider the resin net. ・Consider the cutting wire mesh.
