The auger should not be run empty as this will cause severe wear on the intake end,
and between the auger and the tube – causing the auger to cut through the tube.
Remember
Your are only issued with one set of fingers
– an auger can remove them with great efficiency and they are irreplaceable
The bag filling and weighing machine should be set up on a level floor, and made exactly
horizontal using the adjusters on the legs of the machine (the slope in any direction should
not exceed 2 o ). A flexible connection should be made between the feed auger and the inlet.
It is important to ensure that all linkages and push rods on the machine are able to move
freely and are not obstructed by anything.
The machine can weigh out and fill bags in the range of 2 – 10 kg (the range is stamped on
weigh beams within the machine casing. To set the exact filling weight, locate the front edge
of the large sliding weight to the required position and lock it. Two bags are then positioned
beneath the fillers, and the bag supports are adjusted so that the bags fit properly on the
supports while they are being filled.
A continuous and even feedrate to the filler is needed to achieve accurate fill-weights. Once
this is set, the rate should not be changed without recalibrating the filler. Under no
circumstances, should the machine be over-fed with product or there will be a build-up of
flour in the diverter chute and bagging boxes. Fill and check-weigh six bags from each side
of the machine, discarded the first bag to be filled from each filling head. If needed, adjust
the target weight using the coarse and then fine weight adjusters. The coarse adjuster has a
range of ±750g in 250g divisions. The fine and very fine adjusters are on a screwed rod that
has a overall range of 700g front to back. One turn of the fine weight adjuster will alter the fill
weight by 5g and one turn of the very fine adjuster will alter it by 1g. Each adjuster should be
locked into position when the correct weight has been set. With all adjusters, movement to
the front of the machine reduces the fill weight and movement to the back of the machine
increases the fill weight. Each side of the filling machine should be treated independently.
Any variation in the feed rate or bulk density of the flour requires
the fill weight to be re-adjusted
