We have made a theoretical analysis of the power consumed by the thrower and got nearly satisfactory results. Based on the data, the following calculations have been infered from our experiments on the pressure to grains got in between the blade and the drum of the thrower.
1. The power consumed by the thrower is about 0.03-0.12ps.
2. Power loss increases as the lift becomes higher or the efficiency is increased, but the loss rate decreases.
3. The average pressure on grains got in between the blade and the drum of the thrower is 3-9kg.
4. Degree of the fluctuation in the power consumed by the blade with a nylon wire brush is about a third of that of the blade with on brush.
