Waste limestone environmentally-friendly reuse dry sand making method
The invention discloses a waste limestone environmentally-friendly reuse dry sand making method. The method comprises the steps of riddle, coarse crushing, first screening, fine crushing, second screening, shaping, sand making, humidification and the like. Used equipment comprises a two-stage impact crusher, a shaping machine, a screening machine and the like, and a dry mist dust removal system isused in the entire production process. Used raw materials comprises low-grade waste limestone such as mine high-magnesium and high-silicon, stone scraps, sorted construction waste and the like, and through the cooperation of the production process, the recycling efficiency of waste limestone is improved, the production technology is advanced, and the production process is safe, stable, environmentally-friendly and sanitary, ranking the leading level in the country. Workshop buildings for fine aggregate machine sand making production line are closed, and dust collectors and dry mist dust suppression devices can be adopted to relevant dust raising points, so that the recycling of waste limestone is efficiently achieved, the dust raising is reduced, the method is more environmentally-friendly, the development prospect is better, and the practicability is stronger.
本发明公开了一种废弃石灰石环保再利用干法制砂方法，包括粗筛、粗碎、一筛、细碎、二筛、整形、制砂以及加湿等工序，使用设备有二段反击式破碎机、整形机、筛分机等，整个生产环节中配合干雾除尘系统，使用原料为：矿山高镁、高硅等低品位废弃石灰石，石材下脚料，以及分拣后建筑垃圾等，配合本生产工序，提高了废弃石灰石的回收效率，生产工艺先进，生产过程安全稳定、环保卫生，居国内领先水平，精品骨料机制砂生产线用厂房封闭，相关扬尘点可以用收尘器以及干雾抑尘装置，能够实现高效回收废弃石灰石的同时，减少了扬尘，更环保，具有更好的发展前景，实用性更强。
