Scrap Separation Plants

Iron & Steel Scrap Recycling Plants

Recycling of steel is a very old business and steel scrap is a very valuable resource for the scrap-treating companies and the steel plants. One way of classifying scrap according to its source is to distinguish scrap from steel plants and rolling mills, scrap from the steel processing (new scrap), and scrap from products after their use (old scrap).

  • Ferrous scrap metal is collected either separately or mixed and is then sorted in the scrap yard and then sold to scrap recycling plants or is sent directly to a steelworks.
  • Once the scrap arrives at the scrap recycling plant, different types of metals are further separated and prepared for shredding/sizing. Shredding and sizing is often needed for a further stage of separation. While shredding and cutting, magnetic separation is used to single out the ferrous metal.
  • In the case of stainless steel, larger pieces are collected separately or sorted in the scrap yard before shredding. Smaller particles of stainless steel are separated by multiple-step separations. After separation by a magnet (where the magnetic ferrous scrap is separated out), the non-ferrous metals, stainless steel scrap and non-metal fractions need to be further separated by high intensity separators and/or eddy current separations.

BAS ElectroMagnetic & Magnetic Over-Band Ferrous Metal Separators (EMBS & MBS)

It is a way to separate non-ferrous from ferrous components and it is extensively used in industry. A wide variety of separators are available to perform this task. The most common are BAS EMT electromagnetic drum separators,  EMBS (Electromagnetic Overband Metal Separators – BAS®) and BAS MBS (Permanent Magnetic Overband Metal Separators – BAS®). Scrap moves on a conveyor belt and passes under over-band metal separators equipped with an magnet or electromagnet and the ferrous components exposed to the magnetic field are separated from the scrap, but still, the scrap may contain many impurities such as non-ferrous metals, rubber, plastic, wood, bonded components, etc.

BAS Dry Drum Magnetic Separators

The BAS dry drum magnetic separator is common type of equipment for separating magnetic particles from nonmagnetic particles or relatively strong magnetic particles from relatively weak magnetic particles based on magnetic susceptibility, particle size and shape. The our equipment (Dry Type Drum Magnetic Separators – BAS® (bas-tr.com) is widely used in various industries, iron ore minerals separation, separation of magnetic materials from steelmaking slags, purification of nonmetallic ores, food and plastic processing, Al and Iron&Steel Recycling Plants.

BAS ECS Eddy Current Non-Ferrous Metal Separators

These systems are based on inducing eddy currents in the metals. A time-variable magnetic field, following the Faraday law, generates electromotive forces perpendicular to the magnetic field. If the magnetic field is within a conductive material, the induced forces generate currents in the material, the eddy currents that depend on the material conductivity. The BAS ECS eddy-current non ferrous metal separator (Eddy Current Non-Ferrous Metal Separators – BAS®) is a conveyor tape with a particular magnetic field in the head, which is generated by a high frequency magnetic drum. When the non-ferrous metals approach the magnetic field, they are lifted and rejected to an appropriate collecting chute while the inert materials freely fall down to an another collecting chute. Metals with different conductivity produce various eddy currents and will be thrown away at different distances.
