To date, research on the residence time of individual particles within a vibrating feeder remains limited. In the particle layer of the vibrating feeder, particles located closer to the bottom experience greater influence from the tank's vibration force, resulting in more pronounced movement trajectories. Conversely, particles near the top exhibit smoother and less erratic paths. The vertical movement of particles becomes more intense, and at this stage, the horizontal motion of particles at the bottom is no longer a simple plug flow but involves some degree of back mixing. As the amplitude and frequency of vibration increase, particle movement intensifies, and the residence time of solid particles within the feeder decreases accordingly.
The surrounding environment of an inertial vibrating feeder can be mounted using brackets, which help eliminate negative effects that may arise during operation. The electric vibrator is fixed to the support frame via a spring seat and springs, originally positioned in a hanging manner. The support frame is then welded to an embedded steel plate on the ground. To facilitate spring replacement when the cylinder is damaged, the spring seat is locked and secured, allowing for quick and easy maintenance without disrupting the entire system.
By modifying the installation method of the vibrating feeder, the system operates without faults, achieving a zero repair rate. This also eliminates various safety risks, such as open flame operations in gas areas and the potential falling of the electric vibrator from the hopper. Additionally, the inclination of the vibrating feeder can be easily adjusted, enhancing the overall reliability of the raw coal handling system. This improvement not only increases operational efficiency but also ensures safer and more stable performance in industrial settings.
