Metal Shredder Machine

What is a Metal Shredder Machine and How Does it Work?

In addition to the number of shafts shredders can operate at high medium or low speeds. Typically the types of shredders used in scrap metal recycling operate at low speeds with high torque enabling them to efficiently chew through large pieces of metal.

Large pieces of scrap metal such as crushed old vehicles are fed into shredders on an industrial scale. They pass through the feed pipe into the shredding area where powerful hammers rotate and shred the metal. Magnets are used to separate the shredded material into ferrous and non-ferrous components before it is transported along conveyor belts and finally spat out of the opposite side of the machine in two separate piles for further sorting.

Scrap metal shredders are used to break down scrap metal into manageable moveable pieces. They come in a range of sizes from small units that can shred pennies and tin cans to huge machines with 10000 horsepower motors that can shred 4000 tonnes of metal a day. As part of the end-of-life vehicle recycling process these larger machines shred items such as cars bulk drums and virtually any other type of scrap metal.

Shredders are available with a variety of cutting methods such as horizontal or vertical shafts single double triple or even quad shafts. Depending on the type of material to be shredded several types of blades with claws of different thicknesses can be produced for the shafts. 

The Benefits of Using a Metal Shredder Machine

-The production of hot metal during metal shredding is very high compared to the amount fed in.
-The hot metal produced has a clear precise and consistent chemistry.
-Together with the lower sulphur concentration electrode breakage is reduced.
-The hot metal has greater capacity or endurance.
-The hot metal consumes less electricity per tonne.
-Recycling helps to reduce environmental risks and air pollution.
-When combined with other materials crumbled scrap is easier to handle and produces a dense mixture.
-Ferrous and non-ferrous materials are automatically separated from the shredded scrap.
-Operators can choose to automate or manually operate the shredder controls.

Single Shaft Industrial Shredders

A single shaft hydraulic pusher plate and filter screen are used to ensure precise size reduction. It is used to shred things like cardboard plastic wood rubber and other similar materials.

Double Shaft Shredders

A twin shaft shredder is another name for this type of shredder. Double shaft shredders are part of the double shaft shredding machine. The rotating blades on the two shafts shred a significant proportion of the input material into smaller pieces. Twin shaft shredders also rotate at a constant speed to reduce the amount of dust generated during the shredding process.

Three Shaft Shredders

A three-shaft shredder has three blades each rotating at a different speed. They are most commonly used for shredding metals aluminium food waste hazardous waste and medical waste.

Four-Shaft Shredders

It has four shredding rollers with blades of different sizes. To improve production efficiency pre-shredding and secondary shredding can be performed. The output can also be divided into several sizes.

Grinders

These grinders use abrasives to reduce the input material to small pieces. The output is reduced to half an inch or less. There are horizontal grinders and tub grinders; the latter has a conveyor belt and the former is top leading.

Granulators

Granules are produced from the input material so that it can be used to make new materials. The input material is then reduced to usable granules by the blades of the rotor which is driven by an electric motor.

Commercial Shredders

They have a drum that rotates and has blades on it. The input material is shredded as the drum rotates. Newspapers plastics and wood chips are all shredded.

Commercial Cutter

The slitter as the name suggests is used to reduce wide rolls of input material into narrower rolls. The width of the rolls is reduced. Slitter rewinders and roll slitters are the two types and are used depending on the application and material.

Key Features to Look for When Buying a Metal Shredder Machine

Usability

The most important aspect to consider is how easy the equipment is to use. Whether you are considering a vertical plastic baler or a metal shredder it is imperative that you have a firm idea of how the equipment will be used before making any purchases. To get to the next step work out how much and how often you will be shredding metal.

Safety issues

There are many potential risks when operating machinery such as a scrap metal shredder. The next item on your list should therefore be your safety. Check that the machine is fitted with the necessary safety devices and if so determine whether these devices provide the necessary level of safety while the machine is shredding.

Capacity

If you're interested in how much metal the shredder can handle look at its capacity. Generally speaking if you work with a lot of metal on a daily basis especially in large quantities it is recommended that you use a high-capacity metal shredder. This is particularly true when working with smaller quantities of metal. You'll get the job done faster.

Maintenance and Upkeep of Metal Shredder Machines

1. Routine replacement and maintenance of wear parts:

The blade is a critical component of the metal shredder and is used regularly. Pay close attention to blade maintenance and regular cleaning. Don't wait until the machine is ruined by the unfavourable elements of the environment that the shredder processes. Pay attention to lubrication and cleaning during routine use. 

2. Take effective safety precautions in case the metal shredder breaks down.

It's also important to take maintenance steps to protect the metal shredder equipment from dust corrosion and moisture when it's not in use or idle. Moisture should be avoided as it can cause internal rusting of machine parts. The machine's operating environment is compromised making it easy for it to become paralysed and difficult to repair when it is used again. Many products on the market operate on the same principle substituting seven points for three. Regular maintenance is essential.
