example 1
[0010] Mixing ratio: red mud + gas generation slag + ash slag + trace additives = 25+52+23 (trace additives are)
[0011] (1) Drying of raw materials: According to the above mixing ratio, the raw materials are sent to the tunnel kiln drying chamber for drying to 4% water content.
[0012] (2) Raw material pulverization: grind into powder with a ball mill, and the particle size passes through a 80-mesh sieve.
[0013] (3) Mixing and stirring: the above-mentioned raw materials are mixed evenly in two-stage and double-layer with a double-roller mixer.
[0014] (4) Finished product and packaging: The uniformly stirred mixture is sealed and packaged, which is the finished product of the curing agent.
[0015] The curing agent is used to replace all the lime, cement and sand and gravel in the subbase and base of the secondary road from Chalco to Yuntai Mountain in Jiaozuo City, and meets the requirements of the "Highway Engineering Quality Inspection and Evaluation Standard" after ...

[0017] Mixing ratio: red mud + gas generation slag + mineral processing tailings + sludge = 20+25+50+5 (mass ratio)
[0018] (1) Drying of raw materials: According to the above mixing ratio, the raw materials are sent to the tunnel kiln drying chamber for drying to 4% water content.
[0019] (2) Crushing of raw materials: crushing with a hammer crusher, particle size ≤ 1.0mm.
[0020] (3) Mixing and stirring: the above-mentioned raw materials are fully mixed, and after mixing, water is added to carry out two-stage double-layer stirring with a double-roller mixer, and the amount of water added during mixing and stirring is 12% to 16% of the weight of the mixture;
[0021] (4) Precipitation: Let the mixed materials rest for 24 hours.
[0022] (5) Extrusion molding: Extrude the above-mentioned mixture into strips with a two-stage vacuum brick extruder.
[0023] (6) cutting adobe: the above-mentioned extruded blank is cut into adobe with an automatic vertical strip cutter and a ...
