Suspended Electro Magnet

Suspended Electromagnets are designed for separation of ferrous metal from a variety of overthe belt conveyor applications.

Proven in industries such as mining, recycling, tire shredding, pulp & paper, construction & demolition. Star Trace Suspended Electromagnets offer superior strength and reliability.

Used in high volume low (less than 150mm) product depth applications, suspended electromagnets offer the ability to be turned on & off.

Installation options include in-line and cross-belt configurations to meet the specific needs of your applications.

  • Suspension Electromagnet

As the product on a conveyor belt flows under the powerful magnetic field, ferrous material is pulled out of the product flow and held to the face of the magnet. When using a manual clean model, the collected tramp metal is held in place for as long as the unit has power. In order to clean the unit, the power source must simply be turned off, which instantly releases the metal from the magnets hold.

  • Non-combustible coolant.
  • External expansion tank.
  • Insulated copper coils / aluminium coils.
  • Manganese impact plate.
  • Lift lugs.
  • 1 year limited warranty on coils.

Overband Permanent Magnetic Separator

STAR TRACE Permanent Magnetic Over band separators are powered by ceramic focused flux, strontium ferrite magnets for superior coercive force.

The magnetism in these equipment is produced by an internal assembly of the above magnetic material. This assembly is enclosed in a non-magnetic housing.

Star Trace design concentrates attractive power on the surface where it is needed most.

The magnetic strength of the permanent magnet will match that of the corresponding size of the electromagnet used for the same application.

  • Over-Band-Magnetic-Separator

In Over band permanent magnetic separator, continuous cleaning is made possible by a heavy duty clad belt that encircles the magnet on a series of rotating pulleys.

As ferrous metal is attracted and held by the magnet, the moving belt carries the collected metal outside of the magnetic field where it is then released beyond the product flow.

Special Features
  • For extra protection from tramp iron.
  • For increased product cleaning .
  • For heavy duty separation.

Overband Electro Magnetic Separator

STAR TRACE Overband electro magnetic consist of an air cooled or oil cooled suspension magnet, supporting structure for the discharge belt with drive drum, tail drum and 2 additional idlers where necessary.

Bucket Elevators

Bucket Elevators are among the most common conveyors used for making vertical lifts of bulk materials. The materials being conveyed can vary over a wide range of sizes from powders to pellets. Most of these bulk materials inherently produce dusty conditions within the bucket elevators, creating explosive hazards.

In the grain storage and handling industry, the bucket elevator is considered to be the most dangerous piece of equipment in the process. Good housekeeping and explosion prevention strategies have reduced the average number of explosion per year but to do nothing to mitigate the destructive effects of explosions that do occur.

User Industries

Agricultural, Chemical, Food, Pharmaceutical, Power, Wood Processing.

Mineral Jig

Theory Of Operation

The In-line pressure Jig is unique in its design and use of jigging concepts. The unit is fully encapsulated and pressurised and combines a circular bed with a moveable sieve action. The encapsulation allows the STPL to be completely filled with slurry and water.

As a result, slurry velocity is slowed and water surface tension eliminated improving recovery potential. The screen is pulsed vertically by a hydraulically driven shaft. Length of stroke and speed of up and down stroke can be varied to suit the application. Screen aperture and ragging dimension and material can also be altered for the application.

  • Jig concentrator

STAR TRACE pressure Jig is a high yield, high recovery gravity separation device. It has been successfully installed in both alluvial and hard rock applications.

  • Wet High Intensity Magnetic Separator
Working Principle:

Magnetic yoke fixed on the machine frame, which generate the strong magnetic field together with exciting coil. Rotary ring in the clockwise drived by the rotary device and goes through the magnetic field slowly. There are many separation boxes on the outer circle of the rotary ring, there is the multilayer magnetic medium which is made of magnetic material inside the separation box. When the rotary ring goes through the magnetic field, it would be magnetized and formed the high grade magnetic field. In the mineral processing, the mine slurry goes into rotary ring along with the gap of the magnetic pole and the magnetic particle would be attracted in the magnetic medium surface, revolving to the non-magnetic area. The magnetic particle would be put into the fine tank and the non-magnetic material goes into the tailing. Star Trace series vertical pulsation high gradient magnetic separator is installed with the stable pulsating device, which can make the mine slurry up-down moving repeatedly. The pulsating flow force makes the mine particle in the relaxed status that is effective to discharge the non-magnetic particle, improve the fine grade. Mean while, pulse pulp is conductive to the elimination of magnetic medium, increase the working efficiency.

Ball Mill

A Ball Mill a type of grinder is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.

Ball Mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder.

Industrial ball mills can operate continuously fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion).

Floatation Machines

STAR TRACE designs and manufactures all sizes of flotation cells. Multiple impeller/diffuser configuration can be used to either enhance or restrain mixing depending upon the nature of the ore being treated.

The robust design allows the structure to be self-supporting and thus fewer supporting beams are requires for installation. Metallurgically the hydrodynamic shape eliminates short-circuiting and prevents sanding.

Specially profiled impellers and diffusers enhance efficient pumping of the slurry. Excellent dispersion of the external air feed and homogeneous mixing of the air and slurry all contribute to superior recoveries and grades being obtained. The impellers and diffusers are moulded rubber or polyurethane coated for abrasion resistance.

Leaching Process

Scrap printed circuit boards were selectively smelted at 200°C to produce a metallic alloy having three phases. These phases were identified as a lead-rich phase, a low tin content alpha bronze phase, and a high tin delta phase.

Electrochemical leaching method on this alloy were done in 1 mol/dm3 sulfuric acid or in 2 mol/dm3 hydrochloric acid (adjusted to an ionic strength of 3 mol/dm3). The lead rich phase was more strongly passivated in sulfate media, and in this medium the high tin content delta bronze was more resistant to corrosion than the lower tin alpha bronze phase.

  • leaching tank

In chloride medium the lead phase and both bronze phases corroded readily, but with current densities about an order of magnitude lower than in sulfate medium (static conditions) for the bronze phases. The high tin delta bronze phase was found to form a passivating layer in sulfate media. A similar layer was not seen in chloride medium.

The leaching method in sulfate medium also showed the existence of an alpha bronze phase of lower tin content in the centres of the alpha phase grains. This phase was quite resistant to leaching in sulfate medium.

STAR TRACE offer complete leaching process with highly cost-effective and environmental friendly process.
