Briquetters are used in the process
of recycling for steel turnings, cost Iron borings, copper or brass
powder, etc. Turning specifically are too bulky to fill a melting
furnace efficiently. Normal baling is no solution because of their great
elasticity - The bale would fall apart, as with paper stock or
textiles.
Before turnings can be briquetted they must be chopped, shredded or
broken when they become dense (In the form of Unbroken Swarf). This
process involves double treatment in which very high pressure is exerted
on a small area, a relatively expensive processing method. The standard
sizes of briquette is 12 to 15 cms (diameter) & 10 cms (length).
