本文根据雷庄砂岩试验结果,叙述了砂岩湿法粉碎的工艺流程和设备。介绍了棒磨机作为主要的粉碎设备以一段一闭路粉碎流程即可代替对辊破碎机二段一闭路流程,从而提高了粉碎效率并有利于大型化。文中还介绍了湿式筛分机或直线振动筛作为棒磨机的检查筛分设备;采用水力分级机或螺旋分级机控制砂岩粉产品中超细粉的含量;以及用水洗脱泥方法清除铁杂质等。
Based on the test results of LeiZhuang sandstone, this paper describes the process and equipment of sandstone wet grinding. Introduced the rod mill as the main comminution equipment to replace the roller crusher with a closed loop crushing process, which can improve the comminution efficiency and facilitate the enlargement. The paper also introduced the wet screening machine or linear vibrating screen as the inspection and screening equipment of the rod mill; using the hydraulic classifier or screw classifier to control the content of ultrafine powder in sandstone powder product; .
