Scrap metal refers to metal materials that have lost their original value, including scrap steel, scrap iron, scrapped cars, light and thin materials, scrap home appliances, scraps, bicycles, paint buckets, cans, etc. Metal shredders and metal shredders are both types of equipment used for scrap metal processing. The question of how to select these two types of equipment has always been a headache for some customers who have just entered the industry. Today, the editor will answer customer questions through the following introduction: What is the difference between a metal shredder and a metal shredder?

The core principle of the metal crusher is hammering. Driven by the high-speed and high-torque motor, the hammers on the rotor of the main machine take turns hitting the objects to be crushed that enter the cavity, and the objects to be crushed can be broken through the space formed between the lining plate and the hammers in the crushing cavity of the metal crusher. Obtain sufficient and effective fine crushing, tear the material to be crushed into crushed materials that meet specifications, and the crushed materials are spherical or segmented. The crushed materials pass through the air cyclone sorting system to separate metal and non-metal. The metal shredder can effectively sort the materials for scrap metal with high impurities, so as to better realize the classification and utilization, and at the same time reduce the impurity content in the materials.

The metal shredder is mainly composed of a shredding blade group, a carrying box, a box bracket, a feeding system, a power system, and an electrical control system. The metal shredder is a new type of powerful material crushing device. The equipment has low speed and large torque. Through the shearing and shredding action of the main shaft, it can easily realize the processing of various materials, increase its bulk density, and coarsely crush the materials. It greatly reduces transportation costs and is the core equipment for processing various materials such as scrap metal, scrap aluminum alloy, rubber, and broken bridge aluminum.

The working principle and operation process of the metal shredder are as follows:

1. The material is fed into the shredding cavity of the metal shredder through the loader for processing. For some large-volume materials, a grab bucket can also be used for feeding operation, and the shredder is directly discharged from the outlet of the loader. Cavity, falling into the shredder under the action of gravity;

2. The shredding knife shaft structure of the dual-shaft shredder is divided into two front and rear knife shafts. The two knife shafts rotate independently under the drive of mutual reducers. The two ends of the front and rear knife rollers extend out of the closed frame. On both sides, one end of the driving roller shaft is connected with the hard-tooth surface reducer through a coupling, and provides power to drive the equipment through two independently running motors;

3. The two active shearing roller shafts rotate in opposite directions in the forward and reverse directions. The front and rear shearing rollers are respectively installed by nesting sleeves and cutters. The two cutter shafts realize the mutual engagement of the cutter teeth. , Rolling cooperation, the claws on the tool automatically squeeze and compress the material on the rolling, and the coarse crushing effect of the material is achieved under the joint shearing action of the two cutter shafts and tools;

4. After the material is cut and shredded, it is discharged uniformly through the collector at the bottom of the equipment, and then the material is uniformly output by the conveyor belt for the next round of material refinement, sorting and crushing.

The metal shredder is used to deal with heavy waste or for the coarse crushing of materials before the metal shredder. Since the machine adopts shearing crushing, only the materials are sheared during the processing. If there are other foreign objects attached to the materials, Then, it cannot provide a good processing basis for the subsequent sorting process, so usually a metal crusher is used for secondary crushing after the process.

Through the above introduction, I believe that customers have a certain understanding of the difference between metal shredders and metal shredders. When choosing metal processing equipment, it is necessary to consider material applicability, processing economy and market space for processed materials.
