Selection of shredders

For the selection of solid waste shredder equipment, it is important to choose the right size of shredder. We usually recommend the right shredder based on the material characteristics and the required output size. The size of the shredder is usually selected so that it does not require 100% of the available power to complete the required shredding work.

The reason for this is that as the use time increases, the knives will become blunt, and more energy will be required to shred the material. If the shredder has sufficient surplus power, the user can continue to use it for longer without maintenance before the knives need to be replaced.

We also recommend that when selecting a shredder, the size of the knife box should be considered to grab as much material as possible as long as the power is sufficient. Therefore, in addition to the model and power, factors such as the size and wheelbase of the knife hook, the feed chamber and the material characteristics need to be considered.

What kind of feeding method does the customer use for the solid waste shredding process?

1. Batch feeding

Batch feeding involves pouring a large amount of material into the shredder hopper with a certain grab or loader. Batch feeding is common in the destruction of household appliances, building demolition work or bale material handling. Although batch feeding is simple and direct, it is relatively inefficient. If the size of the shredder box is not appropriate, the shredder is more likely to cause material bridging or accept more material than it can crush at one time under batch feeding conditions.

2. Metered feeding

Metered feeding refers to feeding the material into the hopper at a stable controlled flow rate through a conveyor. If the material can be metered, the shredder can monitor its feed amount and adjust the matching speed of the production line more effectively. The result of metered feeding is fewer reversals or shutdowns. The basic methods are belt conveyors, chain conveyors, etc.
