Pre-Shredders are basically shredding machines that shred mostly waste materials for further processing.

They come in all sizes, shapes, capacity, power, and other features. Pre-shredders can also be mobile as well as stationary according to your requirements.

Let us learn in detail about every aspect of pre-shredders.

Pre Shredder


1) What Is A Pre-Shredder?

Pre-shredders is a shredding machine that uses blades to shred many materials, mostly waste when you feed it.

Pre-shredders basically consists of two rotating shafts on which blades are fitted to shred, tear or shear any kind of materials.

As the name describes, pre-shredders are used to shred materials before they are sent for further processing. Pre-shredders are used primarily to process municipal waste and industrial waste. They are mostly fitted before Hammermill crushers in industries.

2) How Does A Pre-Shredder Work?

The fundamental working mechanism of the Pre-shredder is as same as any other shredder.

In order to understand the working mechanism of pre-shredders, first of all, we need to understand the essential parts of pre-shredders;

Shredding Blades system
Metal shredder

Now back to working mechanism;

First, the feeding system consists of a conveyor belt on which waste materials are placed down to carry to the mouth of the pre-shredder. Waste materials can be of any shape and size according to the shredding capacity of a specific pre-shredder.

The Shredding box is a durable box that holds a shredding blade system and functions as an inlet for waste materials and an outlet for shredded pieces.

Then the Shredding blades system consists of blades mounted on the shaft(s). The rotating blades convert materials into small pieces by tear, shear, or extrusion. The shredding blades have a low rpm but very high torque for shredding.

Then, at last, the shredded pieces come out from the other side of the shredder box.

This is the basic working process you can see in all shredders.
