The invention discloses an industrial waste residue crushing method, which comprises the following operation steps: mixing various industrial waste residues with one another, and putting the mixture into a stirrer for preliminary stirring; heating and cooling circulation: carrying out primary crushing on the mixture obtained by primary stirring by adopting a hammer type crushing device, heating the mixture subjected to primary crushing to 700 DEG C or above, cooling the mixture to 300 DEG C or below at a cooling speed of 100 DEG C/min or above, heating the mixture to 700 DEG C or above at a heating speed of 20 DEG C/min or above, cooling the mixture to be below 300 DEG C at a cooling speed of 100 DEG C/min or above, and circulating for more than two times; and carrying out secondary crushing on the mixture by adopting a hammer type crushing device, cooling and sieving to obtain industrial waste residue powder. The industrial waste residue crushing method can effectively improve the crushing efficiency of industrial waste residues, reduce the crushing difficulty and improve the crushing fineness.
本发明公开了一种工业废渣破碎方法，包括以下操作步骤：将多种工业废渣相互混合，装入搅拌机中进行初步搅拌；升降温循环：将初次搅拌得到的混合料采用锤式破碎装置进行初次破碎，将初次破碎后的混合料加热至700℃以上，以100℃/min以上的降温速度对混合料进行降温至300℃以下，再以20℃/min以上的升温速度对混合料进行升温至700℃以上，再以100℃/min以上的降温速度对混合料进行降温至300℃以下，循环两次以上；将混合料采用锤式破碎装置进行二次破碎，冷却后过筛得到工业废渣粉末。该工业废渣破碎方法能够有效提高工业废渣的破碎效率，降低破碎难度，提高破碎细度。
