Abstract：The intellgent garbage sorting devicecan automatically recognize and clasify garbage，including recyclable garbage，harmful garbage，kitchen wasteand other garbage.Inorder to solve the problemof kitchen waste crushing treatment，the wall-breaking crusher and the double-tooth roller crusher were designed byusing SolidWorks，and thediscrete element particlebonding model of kitchen waste was established inEDEM，then the simulation experiment was carried out based on these2 crushers.The results showed that the percentageof small particles crushed by the wall-breaking crusher was higher，such as 86.2% and 39.9% for the crushing object 1 and object2 in the simulation experiment，and the proportionof particles obtained from the simulation experiment and the prototype experiment were basically the same，with an error of no more than 5% . It could be found that the crushing efectof the wall-breaking crusher was better than thatof thedouble-toothed roller crusher.Above results provided reference for thedesign of the kitchen waste residue liquid separation and treatment device.
