3.2 The actual milling
■ Weigh out 500 g of grain in the flask which was used during the
preparatory stage. The yields can thus be easily calculated
multiplying by 0.2. They correspond to yield obtained in flour-milling
with respect to wheat ground at B1.
■ The 500 g of grain are poured through the spout into the
feed-hopper at right. The spout which is removable has on the
bottom edge a magnet for catching metallic particles which were not
removed during the cleaning process. 
Before each test, check the spout. If metallic particles are present,
remove the spout by unscrewing the star-knob and clean off with a
brush.
❏ Break: Start the grinding by turning the right-hand electric starting
switch (clockwise) which simultaneously controls the distributor
micro-motor and the grinder and sieve motor (make sure that the 2
electrical connectors are live.
Starting the distributor without simultaneously starting the grinder
will cause jamming.
❏ If this happens,
- Start the machine in the opposite direction.
- Clear away the products with a brush through the two sight-holes.
- Repeat this operation several times until the pulley turns freely.
- Replace the cover and start up again.
Grinding time varies with the size of the grain (or the weight of 1000
grains). This takes about 3 minutes.
After grinding 500 g, wait approximately 1 mn 30 so that the sieving
is completed. empty the sieve.
Three main fractions are obtained:
❏ at the end, coarse and fine brans.
❏ coarse semolina in the right-hand collecting-pan.
❏ break flour in the left-hand collecting-pan.
