FINE-LINE

The new FINE-LINE series of HAVER NIAGARA GmbH is the innovative answer to complexities that users face when it comes to dry fine particle screening.

Areas of application

Fine screening of:

  • Industrial minerals (quartz, limestone)
  • Raw materials and products in the building materials industry (quartz and limestone granulate, gypsum, dolomite)
  • Raw materials and products in the chemical industry (inorganic fertilizer, e.g. DAP)

Cut sizes

  • from 100 μm to 3 mm

Applications

  • Classifying
  • Reject
  • Defillering

Advantages

The FINE-LINE is characterised by the modular design of its screen boxes, which comprises a combination of one to three screen decks according to the task at hand and customer wishes.
  • Quick and easy exchange of screen cloth
  • Dust-tight screen box down to 80 μm
  • Minimal energy consumption, less than 0.5 kWh/tonne of input material
  • Integrated material distribution unit

Feeder

Screen cloth

  • Longitudinally tensioned screen cloth.
  • Cleaning with up to 80 Hz (4800 rpm).
  • With multiple screen decks, the above-each-other deck sections can be cleaned simultaneously or in a time-shifted manner.
  • Cleaning duration and number of cleaning cycles are freely selectable for each screen deck and screen section.

Drive crossbeam with impact strips

  • Directly excited screen cloth.
  • For each screen segment, two paired impact strips excite the screen cloth directly from below. The paired impact strips are placed on rubber buffers to form the drive system together with the unbalance motor.

Unbalance motor

  • Operating modes: drive frequence selectable between 50 Hz (3000 rpm) and 65 Hz (3900 rpm).
  • Extremely high screen cloth acceleration with up to 14 g.

Your advantages and benefits

  • An integrated feeder ensures optimum material distribution over the entire width of the screen.
  • Roomy maintenance doors on the side allows easy and quick screen cloth replacement in just minutes.
  • Externally positioned tensioning units allow quick and optimum screen cloth adjustment.
  • Easy screen-cloth tension-monitoring via optical indicator.
  • The fully encapsulated screening box with integrated de-dusting connector keeps the surroundings dust-free and improves on-site work safety.
  • The generated under-pressure at the lower part of the screen box for de-dusting keeps your material on all screening decks close to the screen cloth. In combination with the thin layer screening, this can lead to a 30-50% increase in screening throughput and the highest possible product quality.
  • Low dynamic loads have a positive effect on the steel construction.
  • Reduced power consumption during regular operation minimizes energy costs. For example specific energy consumption with the FINE-LINE 1800x3750 1DC during classification, depending on the input material and cut-size, is considerably below 0.5 kWh/tonne of input material.
  • The excellent screen cloth side dust-proofing keeps improper size particles away from the product.
  • Effective cleaning cycles minimize clogging and thus prevent a throughput reduction and altered product qualities.
