Used Tube Mill Recycling In Detail

By Juana Buchanan


In the mining industry, very many machines are required to make the entire procedure a success. During these processes, the machines used usually depreciate with time. That is why the use of durable devices is recommended. The processes usually involve a lot of heating thus corroding the parts. Therefore, it becomes necessary to re use some of these devices so as to make the process affordable. Mills for instance are such devices. These are usually used in furnaces for letting out steam. They can also be reused. Used tube mill therefore are equally useful.

Most of the pipes come with different speeds. Low speed pipes consisting of rotating cylinders that pass slurry as the end product in ore processing. There are the medium speed ones, which are fitted with large tires in them made to crush coal in mining industry. The pipes are fitted in utility equipment. They direct pulverized coal to the outlet section through multiple pipes initially fitted.

Due to the high temperatures usually subjected to such pipes, their life span usually decreases in a great rate. They depreciate greatly due to exposure of various chemicals since they corrode them most times. In most cases, the already depreciated pipes are sold to local metal dealers if these are beyond repair. However, most of them are recycled and put to other uses, after repair.

Recycling process of these pipes makes them look a bit new. Second hand pipes go through certain vital process in such cases hence make them look brand new. Companies that recycle such pipes have highly specialized plants that deal with such processes. Repairing process begins at this point, by cleaning the tubes first. After dirt, dust and rust is removed, reshaping step process ensuring new shapes are made.

They are then passed in special scanning machines. They detect the defect and mark the area requiring any repairs. This is through the use of laser scanners, which are highly superior and designed to detect defects such as cracking. This machine however, is made up to work at a high speed to eliminate cases of delay in the repairing process at any time of the day.

Reinstatement follows next. This step is whereby the annealed strips are required to seal defects that are found on the machine. The strips are slit and cut. These are then cut into the required sizes. After that they are fixed at the required points.

The strip pickling department is in charge of ensuring that the process runs smoothly. This department makes sure that no faults are experienced during this procedure. This way, it is done in the correct way.

After welding, the pipes have to undergo additional process such as eddy testing, straightening and further reshaping. Since they area already used, the clients may require additional features to be put on such pipes. For this to go through, the client has to specify it in his application. After reshaping, they are ready for desired use and selling then proceeds.
