Industrial shredders are used to process and reduce firm, dense waste materials that need to be disposed of or recycled. Shredding services are used by a large variety of industries, from medical to paper production for recycling, to waste removal and storage. Industrial
shredders are composed of a feed area with blades or gears for crushing or slicing material, and a chute that passes the material into a receptacle or conveyer for further handling. Industrial shredders are often located in large, commercial shredding plants, inside the home or office, or in a truck called a
mobile shredder. They may be small and hand-fed, or large and able to shred thousands of pounds of material per hour. Most shredders, like
cardboard shredders,
metal shredders and
wood shredders are used condense material in the waste and recycling industries.
Plastic shredders and
granulators are almost always used for recycling plastic products.
Hard drive shredders and
paper shredders, specifically
document shredders, are mainly used to protect private information from being stolen by destroying documents and hard drives.
Tire shredders and
chipper shredders are sometimes used to produce certain products like wood chips or rubber pieces used in indoor soccer floors.
The shredding industry offers a couple different ways to service their customers. The most common way, off-site shredding, is widely used by recycling plants for tires, wood, organic materials, old automobiles, scrap metals, plastics and cardboard. In this method, the materials are transported to a shredding facility. Remote document shredding is a service where a driver picks up the materials to be shredded and transports them to the facility, where they are shredded in the same day. Some facilities offer mobile shredding-a service that brings large shredders on a truck to different businesses for the on-site shredding of documents. The trucks are often modified box trucks with industrial-sized shredders inside that may shred up to 8,000 pounds of material in an hour. This service is for businesses such as medical practices or government agencies that need industrial shredding but are required by privacy laws such as the Health Insurance Portability and Accountability Act to witness the shredding of their documents.
Protecting privacy is an important reason shredding is used for some paper products and hard drives. Document shredders may be small, portable and upright equipment used in small offices or private homes, or large, industrial sized off-site or on-site automated shredders that no not require hand feeding, which are used in hospitals, legal offices and government agencies. They protect private correspondence and confidential documents such as medical records or legal documents, and prevent identity theft. Hard drive shredders also protect confidential and private information by physically demolishing platters of hard discs so their contents may never be recovered and fall into the wrong hands. These shredders do what deleting, overriding and cutting holes in disc drives can't-they sever every track completely. Hard disc shredders are often offered by companies that shred paper or microfilm via saw tooth hook cutters.
Recycling is another major function of industrial shredders. Non-classified paper, plastic products, metal scrap and old tires are all products that are shredded and then recycled. Paper products are taken to a paper mill and condensed by shredders that strip cut, cross cut and particle cut paper into small shreds or pieces. They are then reduced to a raw pulp, which is used in the manufacturing of new paper that contains recycled fibers. Plastic products such as drums, pipes, car bumpers and bottles are reduced into fine particles by granulators via a rotor with strong blades and high rotations per minute. The resulting material is then heat treated and converted into other plastic products. Old tires are often cleaned, separated from their steel rims and shredded to produce crumb rubber, which is made into new tires and used in the manufacturing of road asphalt. Crumb rubber is also sometimes used in indoor sports complexes. Metal scrap shredders are they strongest type. They take products such as steel drums, cable, tubing, sheet metal or old cars, separate their metal parts from non-metal parts, put them through a heavy-duty shredder, and then compress them into dense blocks. Steel is often recycled through shredders, as half of stainless steel is produced from scrap metal.
Wood products and materials such as branches, cardboard boxes, crates and particle board are often shredded for recycling or conversion into other products. Chipper shredders cut wood into chip form, which reduces their bulk for easier disposal. Wood chips are also often used in the outdoors as walkways, in playgrounds and in landscaping or gardening. Used cardboard boxes and cartons are often shredded by steel cutters or shears to produce packing material or cut down to a certain size. Other wood waste such as pallets, crates or blocks are shredded and manufactured into briquette presses or prepared for heating furnaces. Industrial shredders may be hand fed by workers (which is rarely still done because of safety concerns), put on a conveyer and fed into the shredder by meter feeding, or loaded by a forklift via batch feeding.

Types of Industrial Shredders
-
are hammermill-type shredders that are big enough to shred entire cars
and compact them into small squares for recycling.
-
are another common type of industrial shredder. Because cardboard is
such a widely used packaging material, the efficient minimizing, removal
and recycling of cardboard is a industry necessity.
- cut wood or other materials in small chips.
-
are machines used for shredding small materials such as plastic bottles.
-
are high-speed rotor equipped machines with large hammers for crushing
material into reduced sizes with up to 6,000 horsepower of force. Hammermills
come in various sizes and material reducing capabilities.
-
have a pump, which powers the motor and is connected to an electric
motor or diesel engine. These shredders can reverse away from the load
and resume forward rotation in less than three seconds. (http://www.hydraulic-lifts.net).
- use attrition and compression to crush material into small pieces.
-
are round and drum-like with multiple cutter inserts that work against
a fixed bed knife. They are commonly used for reducing materials like
plastics, electronic scrap, wood waste and nonferrous metals.
- are heavy-duty shredders that shred metal scrap for recycling purposes.
-
are one of the most common types of material shredders known. They can
vary greatly in size and capacity and are standard fixtures in environments
such as offices and paper mills.
- are machines that cut various materials into small pieces.
- are high torque, low speed shredders with two or more
counter rotating shafts. The shafts have hooked knives capable of reducing
a wide variety of materials such as tires, paper and baled metals such
as aluminum.
-
are used both in junkyards and other rubber recycling centers. They
are slow speed, high torque machines, capable of handling the dense
rubber used in tires and tubing.
-
are used primarily for wood and organic material. They have a hammermill
that rips and tears large pieces of material into smaller pieces, pulling
them below the tub floor and forcing them through openings in grates
below the mill.
Common Terms Related to Industrial Shredders
- Material left from an automobile that has been sent
through an industrial shredder
and all the ferrous metal has been taken out. Sometimes referred to as
fluff.
- Compress materials that
have been shredded by industrial shredders
into dense rectangular bales.
(http://www.iqsdirectory.com/industrial-balers/)
- Compressed material
that have been shredded by industrial shredders, which is bound, usually by wire.
- The material, usually
wire or nylon, wrapped around bales to secure them.
- The depth of
the material is spread on a conveyor belt.
- Cut in two directions by
industrial shredders,
resulting in smaller particles.
- The place
in industrial shredders where material is torn, sliced, crushed or reduced.
- The
separation of material after it has gone through industrial shreddeders, usually from a conveyor
belt. Magnets, eddy current separators, trommels and other downstream
separation equipment is often used.
- A device
for separating nonferrous metals from nonmetallic material that uses a
mechanically driven alternating magnetic field and a non-magnetic metallic
particle. An eddy current is created and the particle is taken from
the fixed field generator.
- The width of the
opening where material is inserted into the industrial shredder shredder.
- Iron-based metals
like steel.
- Shredding machinery for shredding
small materials such as plastics.
- Involving, moved
by or operated by a fluid under pressure.
- Material on
a conveyor belt that needs to be sorted.
- Non-iron based
metals such as aluminum and copper.
- The motor of
the industrial shredder, often configured a number of different
ways including electric or hydraulic.
- A liquid based mixture
or suspension of solids.
- Denoted in "feet
per minute." Determined by shredding continuous forms and materials
and by calculating the length of paper shredded over a given time.
- Shredded into thin
strips. Generally the cut is the length of the material.
- The opening where the
paper or other materials are fed into the shredder. It needs to be large
enough to accommodate the size of material.
- Materials that
industrial shredders are unable to handle because they are too large or too thick
to be shredded.
- Measured in
gallons, the volume of paper or other products being shredded by
industrial shredders that the waste
bag or waste bin can hold.
