2024 high quality shredder
The shredder is currently widely used in the scrap steel recycling market, mainly for shredding thin iron and waste materials such as baby strollers, children's toys, or steel reinforcement materials. Due to its good shredding effect and clean material processing, it is favored by many scrap iron recycling users.

However, in the current market, there are significant differences in the quality of shredders from different manufacturers and brands. Good shredders have good quality, high blade hardness, high quality reducers, long service life, and are less prone to malfunctions. And many cheap shredders are prone to various malfunctions, one of which was mentioned in an article written by Tongfeng Machinery earlier about the problem of chain transmission breaking.
But equipment malfunctions are not the most headache inducing thing, the most frustrating and helpless thing is that there are production problems. Because the equipment is faulty and can still be repaired, but it is difficult to improve it with maintenance techniques if problems arise during production.

There is a big problem that troubles many friends in the scrap iron recycling industry. That's the problem with the shredder connecting the blades. Generally speaking, during normal shredder production, there is no problem with connecting the blades. Usually, the shredded finished material is in a fixed size sheet shape, but when there is a problem with connecting the blades, the material torn out by the shredder is not in sheet shape but in strip shape. This type of strip shape is difficult to pass the audit standards of the steelmaking plant. Even if it passes, the recovery price will be low, and the profit margin will be extremely limited.

The above picture shows normal shredded materials, which will be favored by steel mills and the purchase price will also be higher.
The materials in the above picture are all shredder blades, resulting in non-standard shredded materials.
So why is this situation happening? How to solve the situation where the shredder with a knife only tears out strips of material?
Generally speaking, the situation where the shredder is connected to a knife is mainly caused by several reasons: firstly, the size of the outer sleeve of the shredder spindle is incorrect. A normal shredder has a gap between its blades and the outer sleeve embedded on the spindle, and the gap is very small because if there is no gap, the blades will directly scrape onto the spindle outer sleeve, and the machine will break down on its own. If the gap is too large, then as soon as the material deforms during tearing, it will squeeze out from the gap and tear into strips. Under normal circumstances, the blade size is fixed and will not be changed casually, so the problem lies in the outer sleeve of the spindle.

2、 Processing issues, many manufacturers when making shredders, simply boring the bottom and top of the main chassis through a boring machine, and then machining the bearing holes is considered complete. However, responsible manufacturers usually process the inner wall of the shredder main box to ensure that there are no problems during the use of the shredder after assembly. With this manufacturing accuracy, it is difficult for the shredder to have a continuous cutting. As long as production begins, the shredded material is in an exceptionally beautiful sheet shape.
3、 In some rare cases, when the material is fed through the conveyor, there may be some materials that are already in the shape of strips entering the shredder vertically. At this time, if the blade is processing thick materials, it will fall from the gap and remain the same after processing. This is also why even the best technology and equipment cannot avoid occasional situations where the blade is torn into strips. But this situation is rare and not a common occurrence.
So the solution is also very simple. In most cases, just contact the shredder manufacturer and process a batch of spindle jackets with slightly larger diameters for replacement. If the replacement of the spindle sleeve still does not work, it will be more troublesome and require further processing of the chassis, or even returning to the factory for reassembly.
