The invention discloses a high-efficiency multi-stage crushing device for iron ore, and belongs to the field of multi-stage crushing devices. The device is characterized by comprising a support box, acrushing box, a feeding hopper, a screening net and a fan, the left side and the right side of the lower end of the crushing box are provided with material distributing grooves, two coarse crushing rollers and two fine crushing rollers which are symmetrically distributed are sequentially arranged in the middle of the interior of the crushing box from top to bottom, the screening net is located under the fine crushing rollers, the left side and the right side of the screening net are located in the middles of the upper portions of the two material distributing grooves correspondingly, the lower end faces of the two material distributing grooves communicate with connecting cavities correspondingly, reinforced crushing rollers are arranged in the middles of the connecting cavities, the screening net rotates, crushed materials can be screened conveniently, small-particle materials directly pass through the screening net, large-particle materials which do not pass through the screening netare screened into the two material distributing grooves, repeated crushing machining is facilitated, and when two movable plates are heavily impacted by the materials, the movable plates rotate, andthe impact force of materials on the crushing rollers is reduced.
Description
technical field [0001] The invention relates to the field of multistage crushing devices, in particular to an efficient multistage crushing device for iron ore. Background technique [0002] Ore materials are indispensable materials in the construction field. With the development of science and technology, the requirements for stone materials are getting higher and higher. Most of these stone materials need to be crushed before use, and crushing devices are needed at this time. [0003] When the existing high-efficiency multi-stage crushing device for iron ore is processed, the size of the crushed material is uneven, which affects the crushing quality. At the same time, when the iron ore is transported and processed, the material is easy to collide with the crushing roller, which makes the crushing roller easy to be damaged. Contents of the invention [0004] The invention provides a high-efficiency multi-stage crushing device for iron ore, which aims to solve the problem ...
