Elscint recently manufactured three vibratory bowl feeders for three parts of a razor blade. The first was the top cap which is fitted on the top of the blade with a moisturizing strip attached to it. One particular orientation was required with a speed of 120 parts per minute per row in two rows.
The second part was the protective cap which is the protective cap fitted on top of the blade during packing and handling. The speed here too was 120 parts per minute per row in two rows.
The third part was “Seat”, which is the base on which the blade is fitted and the balance two parts fitted on. This too required a speed of 120 parts per minute per row in two rows.
The orientation possibilities for each of these parts were six and hence providing the required speed was very difficult, if not impossible for most manufacturers. However, Elscint took this up as a challenge and completed all 3 bowl feeders with zero wrong orientation and a speed of between 125 to 140 parts per minute per row (2 rows). Elscint used its Model 400 with an outer track bowl. The total diameter of the bowl was dia 850 mm. Proper overflow arrangement was provided for all the 3 bowl feeders.
