Abstract
A magnetic separator and methods of use are provided for continuous feeding of a material feed flow at high production feed rates without rotation of large heavy steel parts through high intensity magnetic fields. The magnetic separators use stationary magnetic matrices and redirect a material feed flow and a flushing fluid flow between the stationary magnetic matrices. Magnetic fields within the stationary magnetic matrices are modulated based on reception of a material feed flow or a flushing fluid flow to optimize separation processes and purging processes. The magnetic separators also collect and direct the separated components to isolated collection sites.
Claims29
1) A magnetic separator comprising:
- at least one pair of magnetic sieves, comprising a first magnetic sieve and a second magnetic sieve, supported in stationary positions on a static platform;
- at least one pair of flow distributors, comprising a first distributor in a downstream flow of the first magnetic sieve and a second distributor in a downstream flow of the second magnetic sieve;
- a material flow diffusor for supplying a material feed flow from a material supply line and a flushing fluid flow from a flushing manifold, the material flow diffusor being configured to supply the material feed flow and the flushing fluid flow to both the first magnetic sieve and the second magnetic sieve;
- and
- a controller configured to:
- feed a material feed flow to the pair of magnetic sieves during a production run for separating magnetic and non-magnetic components in the material feed flow, with the material feed flow being fed to the pair of magnetic sieves in a continuous flow, and to switch the material feed flow between the first magnetic sieve and the second magnetic sieve without interrupting the continuous flow;
- control a power supply to the pair of magnetic sieves for generating magnetic fields within the pair of magnetic sieves for separation of magnetic and non-magnetic components in a material feed flow that is fed to the pair of magnetic sieves;
- control the flow distributors to switch each flow distributor between a first output position for discharging a non-magnetic product flow and a second position for discharging a magnetic product flow.
