preparation example Construction
[0031] see figure 1 , the embodiment of the present invention also provides a method for preparing cold-set balls, comprising the following steps:
[0032] Step 101: 10-25 tons of iron oxide scale, 50-90 tons of primary dedusting ash and 1-10 tons of water are sequentially mixed to obtain a mixture;
[0033] Step 102: storing the mixture in the digestion bin for digestion, and transporting it to the intermediate bin after being fully digested;
[0034] Step 103: The ash unloading valve below the intermediate bin feeds the mixture into the mixer, and at the same time, adds 2-10 tons of binder to the mixture, and fully mixes and stirs in the mixer;
[0035] Step 104: extruding the mixed material from the mixer mill into balls under high pressure to obtain wet balls;
[0036] Step 105: Transport the wet balls to the finished product warehouse through the conveying equipment, and dry and solidify the waste gas of the sleeve lime kiln in the finished product warehouse to obtain t...
Embodiment 1
[0038] A method for preparing cold-set spheres provided in an embodiment of the present invention includes the following raw materials:
[0039] 15 tons of oxide scale, 5 tons of binder
[0040] 4 tons of water and 76 tons of dust at one time.
[0041] Among them, the use of iron oxide pellets must ensure its moisture and purity. The iron sheet fished from the whirlpool well is stored in a designated place, and it must be dried for more than two days, so that the moisture in the iron oxide sheet is less than 3%. In the embodiment of the present invention, the moisture content in the iron oxide sheet is 0.5%, and the newly recovered iron sheet is mixed with some large pieces and garbage, which cannot be used directly, and is easy to damage equipment such as ball pressing machines and zipper machines. An iron sieve is added at the discharge port of the silo to ensure the particle size and purity of the iron sheet. In the embodiment of the present invention, the particle size ...
Embodiment 2
[0065] A method for preparing cold-set spheres provided in an embodiment of the present invention includes the following raw materials:
[0066] Iron oxide scale 20 tons Polyvinyl alcohol 6 tons
[0067] 6 tons of water and 68 tons of dust at a time.
[0068] Among them, the use of iron oxide pellets must ensure its moisture and purity. The iron sheet fished from the whirlpool well is stored in a designated place, and it must be dried for more than two days, so that the moisture in the iron oxide sheet is less than 3%. In the embodiment of the present invention, the moisture in the iron oxide scale is 2%. The newly recycled iron sheets are mixed with some large pieces and garbage, which cannot be used directly, and are easy to damage equipment such as ball pressing machines and zipper machines. An iron sieve is added at the discharge port of the silo to ensure the particle size and purity of the iron sheet. In the embodiment of the present invention, the particle size of t...
