Abstract
Apparatus for separating a sheet of briquets issuing from a briquetting machine into individual briquets by bending the briquet sheet both longitudinally and transversely to break the connections between adjacent briquets. The apparatus includes a carrying conveyor having arcuate, waveform or sawtooth conveyor slats and a conforming conveyor having conveyor slats with a cross section which mates with that of the carrying conveyor. The conforming conveyor forces the briquet sheet to conform to the slat configuration of the first conveyor and to pass around a pivot means which breaks or separates the sheet into individual briquets.
Claims5
A method for producing individual metallized iron briquets comprising:
- reducing iron oxide feed material by continuous gaseous direct reduction in a shaft furnace to form a hot particulate metallized iron product:
- compacting said metallized iron product by briquetting it to form a densified elongated sheet of briquets connected by both longitudinal and transverse webs;
- cooling said sheet to a temperature less than 425 degrees C.;
- bending said sheet transversely and bending said sheet longitudinally to break the connection between adjacent briquets in both directions thereby separating the sheet into individual briquets.
A method for separating a sheet of hot briquets connected by both longitudinal and transverse webs, comprising:
- cooling said sheet to less than 425 degrees C.;
- bending said sheet transversely at least 10 degrees between adjacent briquets;
- and
- bending said sheet longitudinally at least 10 degrees between adjacent briquets.
