Because the classification of domestic garbage is not enough at present, the fly ash generated by incineration of domestic garbage often contains heavy metal salt and simple substance, so the fly ash cannot be directly landfilled, the fly ash needs to be chelated before being landfilled, the solidified body after the chelation needs to be crushed into particles smaller than 10mm, the heavy metal content in the leachate is detected in an acetic acid leaching mode, and the landfill can be performed after the detection reaches the standard.

The fly ash crushing method used in the laboratory at present is a manual crushing method, and the manual crushing method comprises the following four steps: 1. and (3) filling the solidified body to be crushed into a disposable plastic sealing bag, and sealing the sealing strip. 2. The large fly ash in the plastic sealing bag is firstly beaten by an iron hammer, and is beaten to fine particles. 3. The crushed fly ash is sieved by preparing a sieve tray of a desired mesh number, typically a sieve tray having a sieve mesh diameter of 7 mm. 4. And (3) collecting the sieved solidified body particles by using a disposable plastic sealing bag, and carrying out leaching experiments. The above method has the following disadvantages: a. the existing disposable plastic sealing bag cannot be reused, the utilization rate is low, and the experimental cost is increased; b. the existing disposable plastic sealing bag is extremely easy to break when fly ash is broken, so that solidified body samples are splashed out, and experimental results are affected; c. the prior fly ash pretreatment method is generally divided into three steps of crushing, sieving and bagging, and particularly, continuous repeated operation is required under the condition of a large number of samples, and the steps are complicated, so that the experimental efficiency is low.
