Metals are essential, versatile and can be used in a variety of ways. This material can be used for industrial purposes, such as the manufacture of automobiles, trucks, ships, airplanes and railways. Metals can also be used to make household items, such as frying pans, cutlery and wrappers. A great advantage of singapore metal recycle is that it can be carried out again and again without altering the properties of this material.
The most commonly recycled metals are aluminum and steel. Other metals, such as silver, bronze, copper and gold, are almost never discarded or recycled because of their value. For this reason they do not create accumulation problems as waste.
The metal recycling process
This process is similar to the ordinary recycling process . First, singapore metal recycle are separated according to their properties; That is why it is very important to have basic knowledge about metals, as it will help you to recycle correctly and contribute to a cleaner, greener environment. The metal recycling process works as follows:
It is the first and most important step in the recycling of metals and consists solely of collecting all objects that are made of metal. For this step you must have containers specifically designed to contain metals and be able to organize them.
Some people and companies have created spaces for people to be encouraged to collect different types of metal and take them there in exchange for a payment. These spaces are called metal collection centers. Each metal has a different price depending on where you sell it.
Once the metals are collected, the next step is the selection. This means that what is recyclable is separated from what is not. It is necessary to emphasize that the quality of the recycled metal is very important. Only a recycled product of good quality can be created if the source materials used during the recycling process are of good quality, that is why a strict quality control is carried out during the selection process.
After the selection stage, the next step is to compact or crush the metal. All recycling materials go through this process using machines. This is done so that the material does not occupy so much space in the cellars.
After the metals are fully compacted, the crushing process follows. In this stage, the metals are destroyed in small pieces or leaves to allow them to continue being processed. Although the pieces are small, they have a large surface that can be melted using less energy than would be used if the pieces were larger. Usually, steel is converted into blocks, while aluminum is converted into metal sheets.
The melting of the metals that will be recycled takes place in a large furnace. Each metal is taken to an oven specifically designed to melt each type of metal according to its properties. This particular process consumes a large amount of energy. However, the energy required to melt the metal is less than what is needed to create it from its source materials. The furnace is heated to the exact temperature required to melt a particular metal. This process can take a few minutes or several hours, depending on the size of the oven, the amount of singapore metal recycle to be melted and the temperature of the oven.
When the previous step concludes, the purification process follows. The metal is purified from different techniques. The metal purification is carried out to ensure that the final product has no impurities and that it is of good quality. One of the methods of purification of some metals is electrolysis. Other metals are simply passed through large magnetic systems to remove garbage. Currently, there are other methods of purification depending on the metal that needs to be cleaned.
7.- Solidification of the metal
After the purification process, an automatic band carries the melted metal to a cooling chamber where its temperature decreases and solidifies. In this step the collected metal becomes a solid metal that can be used again. Some chemicals are also added to the melted metal to have more consistency and other properties. In this cooling stage, different sizes and shapes are also given to the metals.
8.- Transport of metal bars
Once the bars have been designed and manufactured, the final product is packaged based on its size and shape. In this way you are ready to transport yourself to the different factories or people who need it. After this, the recycling cycle starts again.
