Methods of improving coal discharge from hoppers and bunkers by mechanical and chemical means
A further understanding of the principles underlying bin-activator operation has been developed. Concepts of incipient flow and vibration induced fluidisation have been introduced. A means of producing a permanently localised state of fluidisation in the boundary between incipient flow and outlet free surface has been suggested and a patent application has been submitted. A laboratory has been furnished to study vibration fluidisation and flow. A vibration table test rig was designed, manufactured and installed together with accelerometer and data processing equipment, to measure the transmission and attenuation of vibrations through bulk materials. Tests on coal showed that much of the internal energy induced by vibration is dissipated in surface degradation and particle comminution.
