The invention provides an environment-friendly
brick drying and
roasting method and
system. The method comprises the steps that environment-friendly green bricks obtained after
extrusion forming are conveyed into a
drying kiln from a feeding port of the
drying kiln; sequentially carrying out primary preheating, constant-speed drying, speed-reduction drying, balance drying and
moisture detection on the environment-friendly green
brick subjected to
extrusion forming through a drying
kiln so as to enable the
moisture content of the environment-friendly green
brick to be smaller than or equal to a first preset threshold value, and obtaining a first environment-friendly brick; the first environment-friendly bricks are conveyed into a
roasting kiln; the first environment-friendly brick is sequentially subjected to secondary preheating,
roasting, heat preservation and cooling treatment through the roasting kiln, and a second environment-friendly brick is obtained; and detecting the performance parameters of the second environment-friendly bricks to screen qualified environment-friendly bricks and unqualified environment-friendly bricks. The problem that the first environment-friendly brick cracks due to non-uniform drying and
high water content is solved, and the yield of the environment-friendly brick is increased.
