Figure 8:
Product yield - Comparison of different crushing methods
For a yield product of 2-30mm size different Si- rods with average weight of 15kg
and 450mm length had been crushed and compared with results of competing
methods.
The size distribution with the HV-process is more accurate and up to 5% more yield
product can be achieved while the under-and oversized material can be reduced.
Furthermore the HV-process can treat full rods and would not require a pre-crushing
step as the other two methods do- this may avoid additionally material losses.
