为响应国家节能减排的号召,四川亚东水泥有限公司卧牛坪矿山在石灰石破碎过程中采取了回掺表土的方法。为了能把表土顺利回掺,同时做到既不降低破碎机破碎效率,又不增加采矿成本,需要新型的破碎机来满足工程需要。目前,双转子破碎机是理想的大型破碎设备,适宜破碎中低硬度物料,与该矿山开采的石灰岩硬度相匹配,且能一次完成粗、中、细碎作业[1]。该矿山对原有单转子破碎机进行了
In response to the national call for energy-saving emission reduction, Sichuan Yadong Cement Co., Ltd. Pingniu Ping mine limestone in the crushing process to take the method of back mixing topsoil. In order to successfully backfill the topsoil, at the same time do not reduce crusher crushing efficiency, without increasing mining costs, the need for a new type of crusher to meet engineering needs. At present, the dual-rotor crusher is an ideal large-scale crushing equipment suitable for crushing medium and low hardness materials, matching with the hardness of the limestone mined in the mine, and capable of completing coarse, medium and fine crushing operations in a single operation [1]. The mine on the original single-rotor crusher carried out
