Embodiment 1
[0027] A kind of waste incineration slag reutilization produces dry powder mortar method, comprises the following steps:
[0028] (1) Crushing: The waste incineration slag is subjected to a metal treatment process to pick out various metals in the incineration slag, and the oval incineration slag is obtained through wet grinding and crushing. Crusher coarse crushing, and then use the drum crusher to grind the sand particles, so that most of the sand particles are elliptical in appearance;
[0029] (2) Drying: place the oval incineration slag in a high-efficiency dryer to dry until the water content in the incineration slag is lower than 2%;
[0030] (3) Screening: the dried incineration slag is sieved through a multi-layer vibrating sieve to screen out particles with a particle size of 40-150 mesh, and the incineration slag with a particle size greater than 40 mesh is recirculated to the step (1 ) broken;
[0031] (4) Blending: Use incineration slag with qualified particle s...
