Elscint recently manufactured a high speed Vibratory Bowl Feeder for feeding of horseshoe nails in bulk. The requirement was to feed the parts in bulk for weighing. After the set weight of nails were dispensed, the bowl feeder was switched off and a pneumatic gate was closed so that no extra horseshoe nail fell out. This helped in accurately weighing the nails. The requirement was to feed 1000 nails per minute. Elscint designed a bowl feeder to feed upto 1500 nails per minute. Additionally an hopper was provided along with a level controller which would accommodate bulk quantity of horseshoe nails. The size of the nails was dia 7.50 mm x 50 mm in length. As the requirement was for bulk feeding, no orientation was required and only lengthwise nails were taken forward. Elscint used its Model 400 with a Cast Aluminium bowl, coated with Elscinthane PU coating for this application.
