The vibrating feeder is the source of the entire production line. If there is a material blocking and sprinkling, the stone production line may be paralyzed in severe cases. Therefore, it is very important to ensure the normal operation of the vibrating feeder. So what are the reasons for the material blocking, sprinkling and non-feeding of the vibrating feeder, and how can we avoid failures and ensure the operation of the equipment? Judging from the characteristics of the material itself, the main reason for the clogging of the vibrating feeder is the high viscosity and moisture. Due to the reduced fluidity of the material, this will cause the usual "wall hanging" and "shed material" phenomena after the material enters the warehouse, especially during the rainy season. The gap between the iron core of the feeder and the armature is too large or too small. If this happens, it will affect the feeding of the feeder because the machine cannot reach the normal amplitude.
