How to Select a Right Industrial Shredder Machine

September 9, 2020     News

Your Material Goal

This is the very first question to ask yourself: what material are you processing? For example, mixed plastics are usually handled by an industrial shredder machine. Pure plastic rejects ( from extrusion, blow molding thermoforming or injection molding) are most often processed in a granulator/crusher.

Nevertheless, voluminous plastic, paper, wood, metal objects often go through an industrial shredder machine before granulating, aka, secondary size reduction. Rocks, minerals, ores, glass and die-cast metal usually go into a hammer mill or jaw crusher.

Your Desired Output Size

Output size determines the difficulty and cost of your project. The size is usually determined by the screen. Taking output size into account would land you in the specific category of shredders. An industrial shredding machine generally produces irregular particles around 40mm (palm size), or stripes around 40-60mm long.

In conclusion, the bigger the screen opening, the bigger the output size, also higher the capacity,

Also, the output size affects the capacity of a shredder and succeeding workflow, which would be mentioned in the next section.

Industrial Shredder Machine Capacity

Capacity is typically expressed in kilograms per hour/day. Or the processed amount per hour from feeding to final output. The capacity may be limited by the screen opening and effective working area (shredding chamber size) and a pusher.

Usually, Wiscon would provide clients a list of capacity based on a 40mm screen. A bigger industrial shredding machine can always produce a bigger amount of materials, but over-sizing shredder results in excessive power use and taking up too much floor space.

Way of Feeding Material to Machine

There are two basic feed types: manual and automatic. Manually fed shredders usually have a hopper and work by either hand-feeding the material or using a forklift or crane to drop in the material. With human intervention, the material stream is taken extra care of.

Automatic: belt/screw conveyors help optimize shredder performance by giving a constant and regular supply of materials to the shredder. Fortunately, Wiscon Envirotech conveyor works with an industrial shredder machine depending on the workload of the shredder. In other words, once the shredder almost hits the workload limit, the conveyor slows down or stops.

Ease/Safety of Operation

Transportability, safety, and noise are concerns when selecting an industrial shredder. Selecting the proper location for the shredder is not easy, because it is not simple to move a machine weighing at least 0.5 tons. An ideal location would be leveled ground with 1m free space around a shredder.

Depending on the material, dust and other airborne particles can be an environmental hazard. Noise is another factor to consider as some shredders create 80dB noise. With proper use of goggles and headphones, it will greatly reduce of work danger. Of course, always focuses on human orientation and work safety.


We all don’t want a shredder to be serviced a lot, because no one wants downtime. However, an industrial shredder is a delicate piece of machine that requires regular maintenance. Daily blade inspection, lubrication and changing gearbox oil are important, and they can help prevent lots of hassles. Ask your supplier, does the shredder equips the maintenance door or access for lubrication.

Some More Questions to Think about

Is the shredder appraised for the ability to meet your necessity?
Is the shredder made by a maker with long-term understanding and notoriety for client support? Choose wise.
Does the supplier choose the right machines, like single shaft or double shaft or four-shaft? Provide details.
Can the shredder handle your material and produces consistent uniform particles you want? Need a pusher ram?
Can the shredder get in touch with moisture material and water? Add water like wet crusher.
Does the shredder have a rotor and shredding chamber size reasonable for your materials? Efficient?
Do you have the power source to meet its power requirement? Startup current.
What are the upkeep necessities, like blade, screen and oil seal?
Does the supplier offer help in model selection, installation, maintenance and aftersales service?

Industrial Shredder Machine Conclusion

Many aspects of a shredder need to consider before buying one. We strongly suggest our client consult with us first. In return, we would provide a detailed business proposal and a technical drawing for your shredding and recycling projects.
