The invention relates to a limestone powdering process in which calcining and crushing equipment is used. The calcining and crushing equipment comprises a calcining cylinder, an extruding device, a crushing device, a supporting base and a heating device, the extruding device is arranged on the inner wall of the right end of the calcining cylinder through a bearing, and the crushing device is arranged on the inner wall of the right end of the calcining cylinder. The supporting base is arranged at the lower end of the calcining cylinder, a heating cavity is formed in the inner wall of the upperend of the calcining cylinder, and the heating device is arranged on the inner wall of the lower end of the heating cavity. By utilizing the characteristics that limestone is easier to break after being calcined and is better calcined after being broken, the limestone is broken while being calcined, so that the problems of uneven internal and external heating, incomplete limestone internal calcination and the like caused by part of overlarge limestone are solved. The limestone is uniformly guided to the high-temperature area, and the too small limestone is guided out through a screen, so thatthe limestone is uniformly heated, and the problem that the limestone is not uniformly heated is solved.
本发明涉及一种石灰石制粉工艺，其使用了煅烧破碎设备，该煅烧破碎设备包括煅烧筒、挤压装置、破碎装置、支撑座和加热装置，所述的煅烧筒右端内壁上通过轴承设置有挤压装置，破碎装置设置在煅烧筒右端内壁上，煅烧筒下端设置有支撑座、煅烧筒上端内壁内开设有加热腔，加热腔下端内壁上设置有加热装置；本发明通过利用石灰石煅烧后更易破碎以及破碎后更好煅烧的特点，边煅烧边破碎，从而解决了部分石灰石由于块头过大，导致内外加热不均匀以及石灰石内部煅烧不彻底等问题；本发明通过将石灰石均匀导向高温区，并将块头过小的石灰石通过筛网导出，从而使得石灰石均匀加受热，并不会产生石灰石受热不匀的问题。
