Metal shredder equipment - one of the essential equipment in the scrap steel crushing production line

The metal shredder is a professional equipment for coarse shredding of various large-volume, high-hardness scrap steel and aluminum. The equipment structure includes a frame, a driving device, a torque limiter, a reducer, a box, a left roller, Right roller, multiple tool assemblies, and synchronization mechanism. The tool assembly includes a cutterhead and a spacer. The left and right rollers are installed in the box. The driving device drives the left and right rollers through a torque limiter and a reducer. Turn in opposite directions. The cutterhead and spacer are combined split knives. The inner holes of the cutterhead and spacer are provided with axial bosses. The left roller shaft and the right roller shaft are provided with axial grooves in the circumferential direction. Through the bosses and the concave The cooperation of the grooves allows the cutterhead and spacer sleeves to be installed on the left roller shaft and the right roller shaft at intervals. The cutterhead and spacer sleeves on the left roller shaft and the spacer sleeves and cutterheads on the right roller shaft are respectively arranged correspondingly. The disc and the spacer are equipped with teeth in the circumferential direction, and the corresponding cutterheads on the left roller shaft and the right roller shaft and the tooth tips of the spacer also correspond to each other at the shearing position, thereby jointly participating in the shearing and tearing of the material, making it easier Tear the material.

The wide application of metal shredders comes from its excellent equipment performance. This equipment effectively solves some problems of traditional metal shredders that are difficult to handle scrap steel and scrap aluminum materials. Shredders currently on the market often have the following problems Three questions:

1. Compared with the traditional single-cycle shredder, the metal shredder adopts a dual-shaft structure and is driven by a motor + belt drive + reducer. For higher power, a low-speed high-torque motor + high-torque reducer is used to drive, and the layout is not simple. It is compact, and the gearbox bears the radial force of the belt, the equipment torque is insufficient, the equipment quality is unstable, and the price is high;

2. Compared with professional cutting equipment such as gantry shears and crocodile shears, the operating efficiency of the metal shredder is superior to these equipment, with an average output of 1-5 tons per hour. The size and size of the materials after cutting and processing are uniform and convenient for material transportation;

3. Compared with the metal crusher, the metal shredder pays more attention to the coarse crushing of materials to facilitate the further fine crushing of subsequent materials. This equipment and the metal crusher can be used together to form a scrap steel and scrap aluminum metal crushing production line.

The metal shredder uses the side blades of the cutterhead on the left and right rollers to rotate in opposite directions to form shear, and transversely shear the incoming materials; for large-volume materials, the materials are squeezed through the claw extrusion method, and the operation efficiency is high. At the same time, it has the function of automatically turning over jammed materials to prevent the machine from being stuffy. At present, it is very common in the scrap steel industry at home and abroad to use metal shredders to shred scrap steel or scrap steel bars so that the material specifications can meet the needs of steelmaking.

The metal shredder drives the left and right rollers to rotate through a motor plus a torque limiter and a reducer. It has a compact layout. The overload protection of the reducer and motor has fast response time, large torque, low cost and short cycle. Both the cutter head and the spacer adopt a split structure, and are installed on the left roller shaft and the right roller shaft directly in conjunction with the dovetail grooves or T-shaped grooves axially provided on the left roller shaft and the right roller shaft through axial installation. Compared with the traditional integrated structure of the cutterhead and spacer, the combined structure of the disc and spacer is more convenient to disassemble and assemble and has better structural stress. The cutterhead and spacer sleeves are equipped with teeth in the circumferential direction. The cutterhead and spacer sleeves are installed on the left roller shaft and the right roller shaft at intervals. The cutterhead and spacer sleeve on the left roller shaft correspond to the spacer sleeve and cutterhead on the right roller shaft. setting, and under the action of the synchronization mechanism, the corresponding cutterheads on the left roller shaft and the right roller shaft and the tooth tips of the spacer also correspond to each other in the shearing position, and the corresponding cutterheads and the tooth tips of the spacer participate together Compared with the extrusion method of the traditional scrap steel shredder, the shearing and tearing of materials is easier to cut.
