Shredder is a piece of equipment used for roughly shredding big pieces of waste/scrap material into smaller sizes prior to granulating process. Along with people’s increased conception of environment protection as well as the development of recycling technology, shredder plays a more and more important role in recycling process. Most localities have laws regarding how to transfer and dispose large volume of manufacturing, office and even household waste, and shredder helps related parties/companies meeting these regulations by reducing large sizes of waste into smaller sizes.

Industrial shredders nowadays are used in wide range of applications including waste paper, tires(tyres), plastic, wooden scrap, e-waste, metallic scrap, hazardous waste, and even animal bones. These shredders basically are made of steel material and equipped with cutting shaft(s) inside the machine chamber for tearing up waste material. Categorized by number of cutting shaft, there are single-shaft shredder, double-shaft shredder, and four-shaft shredders. Single-shaft shredder, also known as single-rotor shredder, is equipped with one high-speed cutting rotor and also a horizontal hydraulic trolley to push material close to the cutting rotor for efficient shredding. Single-rotor shredder is quite a versatile shredding equipment and it is suitable for shredding almost all types of waste material and even whole bales of paper and plastic. Double-shaft shredders are designed with two biting shafts, featuring with high torque, capable for shredding almost all types of soft, high-resilient and hollow wastes. Four-shaft shredder is built with four biting shafts in the machine chamber, and it is known as the most powerful shredding equipment that normally is used for shredding extremely stubborn material such as heavy truck tires, large plastic/metal drums etc.

There is also a kind of shredder that is integrated with granulating/crushing function, which makes shredding and granulating process done in one machine. Such machine is very good choice for waste conversion plants.
Nowadays shredder comes in different size and shapes to meet different demands and different scales of recycling.

Please refer to our topic “HOW TO CHOOSE A SUITABLE SHREDDER” for some guideline to choose a proper shredder for your specific need.

Shredder is a machine that is used for reducing the size of almost all kinds of material. In today’s manufacturing and disposal industries, shredder plays an important role in waste management and recycling processes. Shredding offers a multitude of benefits in addition to the most obvious – size reduction.

For recyclable waste such as tires, metals, wood and plastic, after shredding and granulating they can be turned into raw material for manufacturing new products again. This greatly improves material recycling ratio (MRR), optimizes material usage and reduces waste in the environment & demand on natural resources.

For non-recyclable products that are committed to landfills, on one hand, shredding makes greater compaction of non-bio-degradable materials, allowing disposal of more waste in less area, which greatly saves valuable landfill space. On the other hand, bio-degradable materials can also decompose faster after shredding.

Besides above, shredders are also used for the destruction of confidential documents, prototype/models, discs, tapes, memory stick, hard drives and other data storage media to protect the privacy of individuals and corporate information.

Shredder is quite a necessary piece of equipment for the majority of recycling or waste management companies, as it helps turn big pieces of waste material into smaller size for easiness of storage, transport, and also granulating process. You may ask: “what type of company needs a shredder?” Here are some examples:

• • Waste collection centers, need shredders to reduce the size of solid waste material such as wooden waste (scrap furniture, wood pallet…), plastic purgings, plastic/metal drums, tyres, paper cores, etc, before transporting to waste conversion plants. That is, shredding helps reduce transportation and storage cost.
  • Waste conversion plants use shredders for rough shredding to get smaller sizes of various types of waste, and then go for granulating process, as large pieces of waste cannot be directly granulated by granulating machine. For waste compacted in big bales, those plants use shredders to shred the whole bales into small scraps prior to granulating process.
  • RDF (refuse derived fuel) processing facilities use shredders to shred waste combustible material into small pieces first and then compress the small scraps into uniform bales by a baler. Those bales thereafter are transported to certain places to be burnt to generate steam for electrical power.
  • Tire recyclers use shredders to shred both car and truck tires into rubber scraps and those rubber scraps can be re-used in many ways. For example, it can be mixed with asphalt to build road; it can be converted into rubber powder to produce new tires and other rubber products; it can be used for making barriers to reduce collision.

Some corporations, governments and households use shredders to destroy commercial documents and discs, to protect individual privacy and business secret.

To help choose a most suitable shredder to fit your need, you can ask yourself the following questions first:

1. What type of material will you shred?
Each type of shredder has its unique feature to process specific types of material. For example, plastic drums and bottles/containers are better to be processed by double shaft shredder because its feature of two cutting rotors can efficiently grip the light & hollow material; Thick & solid material such as purgings, wood blocks/pallets, plastic/paper bales are better to be handled by single-shaft shredder, attributing to its high-speed cutting rotor and the hydraulic pushing trolley.

2. What shredding throughput are you looking for?
Shredding throughput is mainly decided by the size of machine including hopper size, shredding chamber size, power size etc. The bigger the chamber is, the more material it can be loaded each time and therefore more efficient; the bigger the power is, the higher capacity and speed the machine can generate. Even for same machine, different material will result in different throughput because some material are easier to be shredded than others. In addition, material original size also affects shredding throughput – material in smaller size gives larger throughput than material in bigger size . For single shaft shredder, your choice of with or without screen will also give different throughput – without screen generates higher throughput than with screen. In conclusion, when choosing a shredder to meet your specific throughput, you have to take into concern for machine size, whether a screen is necessary, and the characteristics & size of your bulk material.

3. Is the feeding mouth of the shredder big enough for your material?
This is to be concerned only when you material is in big sizes, for example car bumpers, big size of carton/cardboard, large drums etc. If the feed opening is not big enough for the material to reach the rotary cutter, the machine does not work for your project at all.

4. Is the space of your workshop quite limited to locate the shredder?
Before purchasing a shredder, you have to think about the overall dimension of the shredder and whether a feeding conveyor in necessary for you to connect with the shredder. Check out the total space required for the whole shredding line including the necessary operation space, so as to make sure the space of your workshop is big enough to locate.

Many factors determine the throughput of a shredder. The first most important factor is that you select the right machine is designed for your specific application in order to reach the ideal throughput goals. Which kind of materials will you need to shred? What is your size requirement after shredding? How will you load your materials into the shredder’s hopper? Which screen size is selected because large holes in the screen can bring much higher throughput? If you want to know more exact throughput rate with your own material, we strongly recommend that you can send us your material and we conduct a trial in our machine on site.

Choosing the right shredder or granulator for your application involves considering several factors to ensure that the equipment meets your specific needs. Here are some key considerations to guide you in the selection process:
