MATERIAL SEPARATORS FOR WOOD, PAPER AND FIBER

Separating the coarse material from the airstream before it reaches the filter unit ensures longer service life, higher reliability and efficient operation of your filtration system.

To do this, different types of separating components can be used.

Moldow offers the three types of separation systems/separator units shown below.

DANSEP MATERIAL SEPARATOR

Material separatorMaterial separation within paper, carton and corrugated cardboard

For the paper and corrugated industries, Moldow offers the highly popular DanSep material separation unit for energy efficient, effective and compact waste and trim separation. The DanSep comes in five different types for air flows from 6,000 to 60,000 m3/h (3,500 to 35,300 CFM).

The DanSep separating unit can be used as the main separation component in your extraction system, and it can be placed directly over your bailer or compactor. A DanSep separator can separate most paper and polymer materials in thicknesses from films to corrugated cardboard.

The DanSeps are available in a HP (High Pressure) model and standard model.

SIZES

Moldow’s DanSeps are manufactured in the following types:

  • DanSep 6 – up to 8,000 m³/h (4700 CFM)
  • DanSep 22 – up to 22,000 m³/h (13,000 CFM)
  • DanSep 35 – up to 35,000 m³/h (20,600 CFM)
  • DanSep 50 – up to 50,000 m³/h (29,500 CFM)
  • DanSep 60 – up to 60,000 m³/h (35,300 CFM)

DanSep 22-60 are available in HP models which can withstand a pressure of -6.000 Pa.

Standard models are designed for -2.500 Pa.

CONCEPT

ADVANTAGES
  • High reliability
  • Efficient separation
  • Low pressure-loss and pressure-less separation
  • Simple and reliable technology that reduces your operation cost
  • Improved working environment
  • Compact unit with large separation capacity

CYCLONE

Cylones for use in Dust Extraction Systems for Dust Separation

For cyclonic separation of coarse material from the air before it reaches the dust collector and filtering unit, a cyclone can be used. The metal construction and cyclonic filtering action allow for the safe separation of all materials even those which are very course or sharp which otherwise might damage typical cloth filters.

In a cyclone, centrifugal force is used to perform the material separation. Air enters the unit and circles the outer body forcing material to travel along the perimeter of the unit until it is slowed by friction and falls to the bottom of the unit.  Air and fine dust flow out of a center pipe to the unit outlet.

Moldow cyclones are manufactured in 6 sizes and designed for air quantities from 0.5 m³/s to 15 m³/s.

The cyclones are designed with a long inlet wrap, which ensures a small pressure-loss resulting in minimal energy consumption. The cyclones are delivered as standard in all-welded, lacquered steel plate, ST 37,2.  They can also be manufactured in stainless or acid proof steel, dipped or with a special surface treatment.

The Moldow cyclones can be used within the woodworking, paper & corrugated and fiber industries.

TRANSFLOW SYSTEM

Transflow Separation Ducting System

The Transflow system can be a great advantage for production facilities within the woodworking industry with large amounts of extraction material as it allows for handling of large dust loads and flexible machinery placement and connection.

As the waste material enters the Transflow, the airspeed is greatly reduced due to the plenum design. This forces all but the finest particles to fall out of the airstream and into the base of the Transflow system where a chain conveyor transports it to a rotary valve situated at the end of the unit. After passing through the rotary valve, the material is transported in a dilute pneumatic conveying system or alternatively to a chain conveyor system and further to a waste silo or container. The light air-borne dust, which remains in the airstream, is passed on to a traditional bag filter system.

The Transflow system is a Plenum type separator with a maximum length of 70 meters. Machines can be connected directly to inlets along the full length of the unit eliminating the need for a branched type duct system. This allows machines to move with a minimum need for new ducts.

CONCEPT

ADVANTAGES
  • Extraction of large quantities of dust and chips
  • Constant pressure: air demand/energy use follows active machines
  • High flexibility: machines can be moved without rebalancing system
  • Cheaper, more efficient fans as waste is removed from the air
  • Higher load – smaller filter
  • Modular construction: can be extended as production grows
