The “secondary utilization” of waste household appliances

Old appliances pile up fast. They fill up our land. This is a big problem. We need to use them again.

Secondary utilization means we take old appliances apart. We get useful materials from them. These are metals, plastics, and glass. We clean them. We use them to make new things. This saves earth’s stuff.

Taking apart old items needs special ways. We need the right machines. A good process helps us get the most value.

How do we process waste appliances?

Old fridges and TVs sit around. They are hard to break down. We need a good way to handle them.

We break down waste appliances into smaller pieces. We separate different materials like metal and plastic. This is done step by step.

Handling waste appliances is complex. Many items have many parts. We cannot just crush them. We need a process that gets different materials out.

Initial Steps

We first check the items. We remove things that could be risky. This might be harmful liquids or gases from fridges. We take out batteries. This makes the next steps safer.

Size Reduction

Then we use big machines called shredders. They cut things into small pieces. This makes it easier to separate materials. Different shredders can be used. Single shaft shredders, double shaft shredders, or even four shaft shredders can work. The type depends on the appliance size and what size pieces we want. We shred metal cases, plastic parts, and wires all together at first.

Material Separation

After shredding, we separate parts. This is a very important step. Magnets pull out steel and iron pieces. These are easy to get. Other machines use eddy current separation. This gets non-ferrous metals like aluminum and copper. Air blowers separate light materials. This includes foam and some plastics. We also use screens to sort pieces by size. This helps clean the materials more. Optical sorters can separate different types of plastic by color or type. This process makes the materials cleaner. Clean materials are worth more money.

We design the whole line. This makes sure every step works with the others. We get the most materials possible.

What materials do we get from waste appliances?

Appliances have many different parts. We want to get the good stuff out. What is inside them?

We get metals like steel, copper, and aluminum. We also get different kinds of plastic. There is also glass and wires.

Old appliances are full of useful materials. Getting these materials is the main goal of secondary utilization. We break the appliances apart to get them back.

Recovered Materials and Uses

Material	Examples from Appliances	New Uses
Steel	Cases, frames, screws	New steel products, construction
Copper	Wires, motors, circuit boards	New wires, pipes, electronics
Aluminum	Heat sinks, frames	New aluminum products, car parts
Mixed Plastics	Cases, inner parts	Plastic lumber, new plastic items
Sorted Plastics	ABS, PP, PS	Specific new plastic products
Glass	Screens, doors	New glass products, insulation
Wire	Power cords, internal wires	New copper wire, plastic material
Printed Boards	Electronic circuits	Recovering precious metals (complex)

Getting clean, separated materials is key. Factories that make new products need pure materials. Equipment of Fude Machinery help make materials clean.

Why is recycling appliances important for the future?

More and more people buy new appliances. Old ones pile up fast. This creates a big problem.

Recycling old appliances protects nature. It saves limited resources like metals. It also creates jobs and new business chances. This is good for everyone.

The number of old appliances grows every year. This is because people upgrade to newer models faster. We call this e-waste. E-waste is a big challenge. It is also a big chance.

Protecting the Earth

Putting old appliances in landfills is bad. They take up space. Some parts have harmful stuff inside. This can go into the ground and water. Recycling stops this pollution. It keeps dangerous things out of nature. It uses less energy than making things from raw materials. Less energy use means less pollution from power plants.

Saving Resources

Earth has a limited amount of metal and other materials. When we recycle, we use the same materials again. We do not need to dig as much new material from the ground. Making aluminum from old aluminum uses 95% less energy than making it new. Recycling steel saves a lot of energy too. This saves earth’s limited stuff for the future.

Rules and Laws

Many governments around the world now have rules for e-waste. They require companies to collect and recycle old electronics. These laws make recycling a must-do activity. They push for better recycling methods. These laws mean more business for companies that recycle. They also mean more need for recycling equipment.

New Business

Recycling is a new industry. It creates jobs in collecting, processing, and selling materials. It also creates business for companies that make recycling machines. It helps make a ‘circular economy’. In a circular economy, we use things again and again. This is better for the planet and creates long-term business. This is why appliance recycling is a growing trend for the future.

Recycling appliances is good for the earth and good for business. It is a necessary step for a healthy future.

What equipment is needed for this process?

Taking apart appliances is hard work. We need the right tools. What machines do this job?

We need strong shredders to break items. We need conveyors to move materials. We also need separators to sort different parts. Screens size the materials.

Building a good appliance recycling line needs different types of machines working together. Each machine does a special job in the process. We make these types of machines. We know how they work together.

Shredding Machines

The first main machine is the shredder. We use big, strong shredders. They can break down whole washing machines or fridges. Double shaft shredders or four shaft shredders are often used first. They cut large items into smaller, manageable pieces. Single shaft shredders can be used after for finer shredding. They make the pieces even smaller. This helps the separation machines work better. We make shredders that are strong enough for metal and plastic mixed together.

Moving Materials

After shredding, the material must move to the next machine. Conveyors do this job. Belt conveyors are common. They move the shredded mix from the shredder to the separators. We need reliable conveyors. They keep the whole line moving smoothly. We make strong conveyors that can handle heavy materials.

Sorting Machines

Separating the different materials is key. Magnetic separators use strong magnets to pull out iron and steel. Eddy current separators create a changing magnetic field. This pushes away non-ferrous metals like aluminum and copper. Air separators blow air through the material. This lifts lighter plastic or foam away from heavier metals. Screens shake the material. They separate pieces by size. This helps get clean materials. Each type of separator cleans the material more.

We can provide all these machines. We make them strong for industrial use. They are built to handle tough materials like appliances. We can also customize the machines.

Secondary utilization of old appliances saves resources. It protects nature and makes money. We provide the machines and lines to do this.
