Crushing device for limestone machining

Abstract

The invention discloses a crushing device for limestone machining, and relates to the field of limestone crushing machines. The crushing device comprises a bottom supporting frame, wherein a rotary bin is arranged at the front end of the bottom supporting frame, the rotary bin is of a semi-arc shape, a crushing device body is located in the bottom supporting frame, the crushing device body and the rotary bin are matched with each other to circularly crush limestone, a mounting transverse plate is arranged on the back of the bottom supporting frame, an impact crushing device is arranged on the mounting transverse plate, and the impact crushing device conducts impact crushing on the limestone conveyed by the crushing device body. According to the device, the limestone is thrown onto a crushing plate to be crushed through a roller rotating at a high speed and a crushing claw, then the limestone is extruded and ground through the crushing claw and an extrusion plate, the limestone which falls on a screening plate and is not crushed completely is crushed again through a crushing cutter, and the crushing claw and the rotary bin carry large limestone which is still likely to remain again and throw the large limestone to the crushing plate again to be crushed again, and it is guaranteed that the crushed limestone particles are uniform.

Description

technical field [0001] The invention relates to the field of limestone crushing machines, in particular to a crushing device for limestone processing. Background technique [0002] In the process of traditional limestone production and processing, because the limestone ores mined are of different sizes, it is extremely inconvenient for larger limestones to be processed later, so it is usually necessary to crush the limestone first. The commonly used crusher is generally a roller Extrusion type or hammer type, the roller extrusion type cannot smoothly transport the ore to the counter-rotating rollers for crushing when facing larger ore, and the hammer mill cannot guarantee to crush all the ore when crushing. The ore is crushed into suitable and uniform particles, and the crushed ore often has different sizes. Contents of the invention [0003] The object of the present invention is to provide a crushing device for limestone processing to solve the problems raised in the ab...
