Proportion distribution of adding residual anode in electrode paste

How much more proportion * of residual anode is added to the electrode paste? And in what form is it added?

Residue is mainly used for making aggregates. The particles are large, small and medium in proportion, but this thing can’t be told. It’s a secret. If it is used for grinding, the cost is high, and if it is used for dust collection, the ash content is high, which has a great impact on the resistance.

When adding into the furnace, the fine particles should be screened out to avoid the increase of ash content and resistivity.
