High consistency pulper

High consistency pulper
  • Batch pulper that operates with high consistency pulp producing vigorous rubbing among fibres giving rise to a shive-free pulp.
  • Essential for de-inking installations with a high degree of ink separation and favourable consumption of chemical products and steam.
  • Successful applications in W.S., cellulose and O.C.C.

Medium and low consistency pulper

Medium and low consistency pulper
  • Pulper for continuous pulping or batch pulping at consistencies of between 3 and 8%.
  • Rotor designed for high pumping and disintegration performance with favourable energy consumption
  • It is used for the disintegration of waste paper, cellulose and installations for the treatment of broke resulting from the manufacture of paper and converting.

Pear-shaped disposal unit and pear-shaped cleaner

Pear-shaped disposal unit and pear-shaped cleaner
  • An auxiliary pulper which is applied to pulpers used for batch pulping or continuous pulping of waste paper, increases efficiency up to between 20 and 25% and extracts pollutants intact.
  • It does away with the need to clean the pulper, stabilises the consistency of the discharge and saves on energy.

Thick pulp purifiers

Heavyciclon
  • A highly effective thick pulp purifier used for separating metals, stones, thick grain sand.
  • It is usually positioned at the beginning of the pulp circuit and protects the deflakers and refiners as well as the screen sieves thus saving on the cost of spare parts.
  • It is able to operate with pulp consistencies of between 1.5 and 5%.

Vibrating sieves

Vibrating sieves
  • Thanks to the sheet metal used for screening, perforated with cylindrical-conical holes and their high vibration frequency, the vibrating sieves are highly effective.
  • They can operate at variable concentrations and flows.
  • A very good evacuation of rejects is guaranteed.
  • The use of a vibrating sieve is recommended whenever it is necessary to recover the good fibres which are mixed with the rejects.

Horizontal screens

Uniscreen

Uniscreen

  • This screen extracts pollutants extremely effectively from consistencies of between 2 and 3.5% with a weak flow of pulp in that of the rejects.
  • It is very stable when operating and does not clog. It can be equipped with perforated or grooved sieves.
Multinet

Multinet

  • Double screen with an initial chamber with a perforated grill for preliminary screening as well as a light deflaking and a second chamber equipped with a grooved sieve for fine screening.
  • An input consistency of up to 5% and an output consistency of up to 3.5%.
  • It makes the pulp circuit simpler and is a great saving on energy.
Tailnet

Tailnet

  • Very effective last stage screen with automatic washing cycles preventing loss of fibres.
  • Can be equipped with a perforated grille and even a deflaker and with a grooved sieve.

Equipment for flotation de-inking

Flottank

Flottank

  • A highly efficient de-inking cell where 1 or 2 cells are sufficient to obtain high levels of whiteness.
  • De-inking by suction with low fibre loss.
  • Secondary cells are not necessary.
  • Saving on installation space and low energy consumption.

Circular-shaped thickeners

Circular-shaped thickeners
  • Thickening from an input consistency of 1,5% to 4% without a press roll and up to 6% when using a press roll.
  • Low fibre content in strained water.

Inclined Screw Thickeners

Inclined Screw Thickeners
  • Can be used with all types of pulps and has an excellent thickening and cleaning effect working with input concentrations from 2% and output concentrations of up to 16%.
  • Stable performance, no clogging and needs little installation space.

Screw Press

Screw Press
  • Double sieve draining area and pressure area (high pressure) in two parts.
  • Double casing.
  • Worm screw with anti-wear and tear coils designed in accordance with application.
  • Pneumatic pressure regulation system.
  • Construction: the parts in contact with the product are manufactured in stainless steel.
  • High resistance.

Dispersion

Dispersion

LICARís heat treatment system makes it possible to obtain a highly homogeneous pulp from recycled paper thanks to:

  • Total dispersion of wax, paraffin, inks, pigments etc., by means of a combination of a mechanical action and a temperature of between 60ºC and 100ºC.
  • Dispersion and separation of hot-melts.
  • Subsequent separation of glues by means of changes in temperature.
  • Combined friction and temperature actions resulting in the fibrillation of moisture resistant paper.

Compacting press

Compacting press
  • It is installed in the impurity discharge point of the auxiliary pulpers (Netpulper and Dumpulper).
  • The action of a hydraulic press dehydrates the pollutants, thus reducing the volume, and transports them away from the area where the pollutants from the pulper are discharged.

Horizontal agitators

Horizontal agitators
  • For storage tanks, mixing and machine head.
  • Wide range of diameters.
  • Low energy consumption.

Machine head

Low consistency Cyclonic Purifiers

Low consistency Cyclonic Purifiers
  • Highly efficient in the separation of heavy and light impurities.
  • Various cyclonic purifiers are installed and they are highly efficient in the separation of impurities with no fibre content in the rejects.

Pressure-closed Purifiers

Pressure-closed Purifiers (Ultranet)

Ultranet

  • Especially for machine head circuits before the input box.
  • It works centripetally with an extremely low pulse level.
  • It can be equipped with sieves with holes or grooves.
  • It can also be used in pulp preparation circuits for fine screening.

Pulper for the pulping of Wet and Dry Broke

Pulper for the pulping of Wet and Dry Broke
  • Pulper for disintegrating paper when there are breaks in Presses, Size-Press.
  • The pulper is installed at the bottom of the machine.
