Magnetic separation

What is magnetic separation?

Magnetic separation is a method based on the difference of mineral magnetic, bearing different forces in the magnetic field of magnetic separator, resulting in material separation.  Magnetic separation is one of the most reliable ways to remove unwanted ferrous metals during the processing of raw materials and can also be useful in the process of mining iron.

What industries is magnetic separation used in?

There are many industries which use magnetic separation. These include:

  • Aggregate and mining
  • Food processing
  • Textile industries
  • Pharmaceutical and chemical industries
  • Wood processing
  • Pallet recycling
  • Tire recycling

Magnetic Separation

What types of magnetic separation equipment are there?

The range of magnetic separation equipment commonly used in the mining and mineral concentration industry is divided into two categories. These include low-intensity and high-intensity mineral separators.

Low-intensity separators include overband magnets, suspension magnets and magnetic conveyor pulleys. These are used primarily for the extraction of tramp iron mined product. It provides a cleaner, metal-free product stream and ensures protection to any valuable downstream processing equipment. On the other hand, high-intensity separators are suitable for either wet or dry processes and are used for the concentration of finely sized paramagnetic minerals.

How does magnetic separation work?

Minerals fall into 3 categories including ferromagnetic, paramagnetic and diamagnetic.  Ferromagnetic minerals are magnetic and therefore can be easily separated from other minerals with a magnet. Magnetic separation is used to separate minerals based on their magnetic properties. The magnetic separator used usually consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near the exit.

Gearbox repairs

A gearbox is a device which is used to increase as well as decrease torque (this is a twisting force which causes rotation) through the increase or reduction of speed. Therefore a gearbox is used to change the speed of a moving vehicle. Due to wear over time, gearbox repairs are needed. There are a variety of issues that could go wrong and then need repairing.


Signs that your gearbox needs repairing:

Your gears are slipping

When you are putting your car into gear it should not slip out and if it does, it is obvious that you have a fault. A likely cause of this is that the gears themselves are worn down and will have to be replaced. If you do not repair this, it will only get worst over time.

Gears are noisy whilst in neutral

If you are hearing a lot more noise then you usually do when your car is in neutral, then double check the levels of fluid and try topping it up as it could be low levels of transmission fluid causing this problem.

Burning smell from your car

When it comes to your gearbox, a burning smell can be caused from the transmission fluid overheating. If you ignore the burning smell and do not get a gearbox repair then this could lead for you to have an entire transmission replacement.

Shaking or grinding

A car should never shake, however grinding and shaking is a common symptom of a faulty gearbox when you move from one gear to another. If you ignore this issue, it will only get worse and you will end up acquiring a higher repair cost.

Along with all these signs, there are a variety of other signs that you should look out for as these are only the main factors. These include:

• Leaking fluids

• No response from your gearbox

• Strange noises from the gearbox

• Won’t go into gear

Whether your gearbox needs fixing or replacing, the price will vary from one place to the next but you should get the problem fixed as soon as you can possibly do so to stop yourself incurring a higher gearbox repair cost.
