When it’s time to replace shredder knives?

When considering the productivity of the crushing system, tool life is one of the most important aspects to consider. Understanding how to identify the service life of the chamber or determine when replacement is necessary is a key level to maintain optimal system operation. So how do you know when to replace the tool? Any operator can visually inspect and evaluate through some simple methods to help make these decisions.

One of the simplest methods is to visually inspect the extent of tool damage. If you see a chamber filled with chips and chisels, or if there are multiple missing hooks, it may be time to consider replacing them. The hook on the cutting tool is used to pull the material into the bite of the shredder for processing. If the hook is damaged or lost, you will not be able to operate with optimal performance. If you notice a missing hook on the tool, you can do some simple mathematical calculations to determine the potential throughput loss you may encounter. For a simplified example of this equation, assuming a total of 40 hooks in a room, if 10 of them are lost or damaged, the throughput may decrease by 25%! If there are no other considerations, you will run at 75% of peak performance.

Another method to determine tool wear and when to consider replacement is to check the roundness of the tool edge, that is, the entire outer circumference of the tool. Considering that the knives in the chamber are like multiple scissors, the two opposite edges of the knives cut or cut the paper between them. When the scissors become blunt, it becomes difficult to cut. This will reduce the amount of materials you can handle and make the entire system more difficult to operate, ultimately resulting in additional costs and downtime.

The last simple way to measure when to replace a tool set is to monitor the throughput you see over time. If the time to process the same material starts to get longer and your throughput is decreasing, you will spend more time doing the same amount of work. Always remember that sharp knives not only help save time, but also help save operating costs such as fuel and engine maintenance (dull knives can put pressure on the engine and apply unnecessary pressure to the transmission system).
