The invention discloses a preparation method for formed
coke and a piece of equipment, in particular to a method of using
coke powder or
anthracite, mill
coal as primary material, adding
powder normal temperature
adhesive and
coal tar powder, fully mixing, cold molding and performing, putting the
coke adobe into a tunnel
carbonization stove, giving a low temperature oxidation treatment to the coke
adobe, to produce formed coke with a high quality. The forming equipment is over 24 times more efficient than the existing equipment by using multicavity composite mold and automatic feeding-ejection apparatus; the material needs no
processing of
drying and heat plasticizing; the elementary composition of the body can be adjusted freely; the formed coke has low
sulfur content, low ash content, high
fixed carbon content, no
smoke in the
combustion, high iron-coke ratio and good watertightness in the long time preservation. The investment scale with the same production capacity is only one twentieth of the heat seal -
carbonization method; the working procedures of material
drying, heat kneading, high temperature
carbonization are saved, not only the
production control becomes easy, but also the production process is more energy-saving; the tunnel type oxidation (or carbonization) stove realizes a
continuous operation, has a large yield, and improves the productivity.
