When it comes to shredding various materials, it is essential to use the right type of shredder to achieve optimal results. For instance, a high-speed chipper is ideal for shredding tree branches, while a granulator (rotary knife cutter) is best suited for processing plastics. However, for bulky plastic shapes, a shredder can be used as a first stage before granulation. For more heavy-duty applications such as shredding cars, a hammermill is often the preferred choice. In situations where versatility, minimal noise and dust are a priority, a twin-shaft shredder may be the optimal solution for effectively processing a wide range of waste materials.
Understanding the output size requirement will help in determining the type of equipment to install. Some facilities require the material to be separated, whereas others may need re-shredding and grinding. A single-pass shredder will cost less but if the material needs to be reduced to a very small size and compressed then compaction equipment may be required.
Choosing an industrial shredder to handle the correct capacity is important to the success of any installation. Capacity is typically expressed in pounds per hour and is determined by the physical size, weight (bulk density), and the amount of material to be shredded. The capacity may be limited by the cutting chamber size. Check the capacity rating carefully before purchasing the machine and allow for some excess capacity. Using a shredder with a maximum capacity too close to the desired capacity can lead to a shortened service life. However, over-sizing a shredder by a wide margin can lead to excessive power use and take up too much floor space.
Two basic feed types are common: manual and automatic. Manually fed shredders usually have a hopper and work by either hand feeding the material or using a fork lift to drop the material in. Automatic feeders or conveyors help optimize shredder performance by giving a constant and regular supply of materials to the shredder.
Portability, safety, and noise are concerns when selecting a shredder. Select the proper location for the shredder because it is not easy to move a machine weighing a half ton or more. Depending on the material, dust and other airborne particles can be an environmental hazard. Noise is another factor to consider as some shredders (such as hammermills) create more noise than others.
Shredders endure a great deal of stress and maintenance is necessary to keep them running efficiently. Cutters, blades, or hammers will wear under normal use and require sharpening, adjusting, or eventually replacing. Consider maintenance, repairs, and ease of obtaining replacement parts when choosing a manufacturer. Always evaluate the access location for maintenance when determining where to locate any equipment including your shredder.
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.
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.
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.
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.
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.
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?
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.
