Embodiment 1
[0071] A kind of method utilizing coal gangue to prepare mesoporous material, it comprises the following steps:
[0072] S1: Raw material testing, chemical composition and phase analysis of coal gangue raw materials, limestone or phosphogypsum raw materials, to obtain the chemical composition and content of coal gangue, limestone or phosphogypsum;
[0073] S2: Raw material crushing, the raw material is crushed by a crusher to obtain powder; further, the raw material crushing is divided into two steps, that is, coarse crushing and fine grinding. Yes, the jaw crusher is used for coarse crushing to obtain granular raw materials. The main purpose of coarse crushing is to crush the large coal gangue raw materials into granular raw materials, so that the coal gangue can enter the fine grinding equipment Second, the granular raw materials are sent to the fine grinding equipment for grinding. The preferred fine grinding equipment is a ball mill to obtain powder. Usually, the powder th...
