The invention relates to a
copper tailing
powder ceramsite manufacturing method. Raw materials adopted by the
copper tailing
powder ceramsite manufacturing method comprise 70 to 80% of
copper tailing
powder, 10 to 25% of
fly ash and 5 to 10% of
coal powder. The copper tailing powder ceramsite manufacturing method comprises the following steps of
drying the copper tailing powder by an oven, sieving, carrying out metering processes respectively on the sieved copper tailing powder, the
fly ash and the
coal powder, feeding the sieved copper tailing powder, the
fly ash and the
coal powder into a mixer to carry out dry stirring for about 2 minutes, adding water into the mixture until the volume of the water is a half of that of the mixer, carrying out wet stirring for about 2 minutes, feeding the wet powder obtained by the wet stirring into a prilling disc, adding water into the wet powder to carry out prilling, putting the copper tailing powder ceramsite raw
pellets obtained by the previous step into a static continuous
sintering kiln to carry out
sintering, taking out the sintered products from the static continuous
sintering kiln, cooling, crushing, and screening. The copper tailing powder ceramsite manufacturing method is characterized in that the copper tailing powder subjected to
drying, sieving and metering, the metered fly ash and the metered coal powder are dried and mixed in the mixer, then are subjected to wet stirring, and then are added with water to form the copper tailing powder ceramsite raw
pellets; and the copper tailing powder ceramsite raw
pellets are fed into the static continuous sintering
kiln for sintering to form desired products after three processes of preheating, sintering and cooling.
Copper tailing powder ceramsites obtained by the copper tailing powder ceramsite manufacturing method has the advantages of high waste copper tailing powder
utilization rate, high strength and low water absorption.
