LF-double rotor ultra-fine crusher

The invention discloses an LF-double rotor ultra-fine crusher, and belongs to the technical field of crushing sand-making and coal crushing equipment. The LF-double rotor ultra-fine crusher mainly comprises a shell 11, a rotor 12, a power system 13, a hydraulic cylinder 25 and other assemblies. The crusher abandons a traditional crushing form of sand-making equipment, and adopts a mode of two groups of rotor phase back rotation for high-efficient crushing, thus the proportion of fine particles of crushed materials (particle sizes are less than 4.75 mm) is greatly improved to 85% or above, andthe output of the fine particles is up to 500 t per hour. The equipment plays an improvement role in improving the efficiency of fine crushing of sand and gravel, coke, coal, slag and other materials,and especially plays a key improvement role in improving the amount of sand in the sand-making process. 本发明公开了一种LF-双转子超细破碎机，属于破碎制砂、碎煤设备技术领域，主要包括机壳11、转子12、动力系统13、液压缸25等组件，本破碎机摒弃了传统的制砂设备破碎形式，采用2组转子相背旋转方式进行高效破碎，极大提高了被破碎物料的细颗粒(粒径
