Scrap steel crushing device

Abstract

The invention discloses a steel scrap crushing device, which comprises a main body, a first crushing knife roller set and a second crushing knife roller set, a feeding port is arranged directly above the main body, and the first crushing knife roller set is installed on the main body The upper end of the inner cavity, the front end of the feed port extends obliquely to directly above the first crushing knife roller set, the second crushing knife roller set is fixedly installed directly below the first crushing knife roller set, and the first crushing knife roller set A material guide channel is set between the crushing knife roller set and the second crushing knife roller set, and a first motor is fixedly suspended on the outer wall of the upper end of the main body, and the first motor rotates with the first crushing knife roller set through gear transmission. The second motor is fixedly installed on the outer wall of the lower end of the main body, and the second motor is connected with the second crushing knife roller group through a large gear and a pinion. The invention is simple in operation, and adopts a multi-stage cutting and crushing method to cut and crush scrap steel in all directions, and the crushing is sufficient and thorough.

Description

technical field [0001] The invention relates to the technical field of steel scrap crushing, in particular to a scrap steel crushing device. Background technique [0002] The phenomenon of new and old replacement in the use of metal products is inevitable. Due to the corrosion, damage and natural elimination of metal products, a large amount of scrap metal is produced every year. If these waste metals are discarded at will, it will not only cause environmental pollution, but also waste limited metal resources. Among them, the performance of scrap steel is extremely prominent, which needs to be recycled and reused, and then enter the forging furnace for forging steelmaking. It needs to be crushed and cut to cut and break the large steel scrap into small steel blocks, but the existing crushing device is not completely crushed and the crushing efficiency is low, so it is necessary to design a scrap steel crushing device that adopts a multi-stage crushing mechanism It is cut an...

If these waste metals are discarded at will, it will not only cause environmental pollution, but also waste limited metal resources. Among them, the performance of scrap steel is extremely prominent, which needs to be recycled and reused, and then enter the forging furnace for forging steelmaking. It needs to be crushed and cut to cut and break the large steel scrap into small steel blocks, but the existing crushing device is not completely crushed and the crushing efficiency is low, so it is necessary to design a scrap steel crushing device that adopts a multi-stage crushing mechanism Cutting and crushing it makes the crushing more fully and thoroughly
