When using coal briquette machine to make coal briquette, the compaction pressure will influence the strength of coal briquettes.

When using coal briquette press to make coal briquette, moisture content will influence the strength of coal briquettes.

When using coal briquette press to make coal briquette, time of compaction will influence the strength of coal briquettes.

The size of coal powder affects the mechanical properties of coal briquettes, the size and shape of resulting coal briquettes also affect the product strength.

It is definite that strength is one of the most important properties of coal briquettes, it represents the rank of coal briquettes.
