Hoffman kiln in brick production line using all kinds of industrial waste, slag, coal gangue, river sand, slag, coal cinder, etc as the basic raw material. It increases the thickness of each part of the base,improve the flexural strength and stability.
As experiences one standard size (240*115*53mm) solid clay brick need about 500 kilocalorie heating. If raw clay mixed with coal, every final red brick need about 0.1kg coal (4500kcal/kg).
