Hogged wood without expensive impurities The VARISORT impurity separator is used for the examination of pre-crushed hogged wood. The combination of different sensor units in one complete system allows exact adaptation to the customer specific separation tasks. Common advantages of all impurity separators of the VARISORT series: Highest throughput capacities due to sorting on a high-speed conveyor belt with a speed of up to 3 m/sec. Minimum loss of good material because of blow-out valves developed especially for this application Continuous documentation of all the relevant quality and process data due to integration in the VISUTEC data management system

Inspection of hogged Wood: Impurity Detection Module and separating unit

Modular design - exactly for your application VARISORT M - reliable separation of metals The VARISORT M impurity separator reliably removes all kinds of metals (ferrous & non-ferrous) from the stream of hogged wood. It not only reliably separates loose metal impurities, but also material composites of wood and metal, and metal particles that are included in wood. Whereas conventional metal separators may have difficulties with the separation of certain metals such as high-grade steel, this is absolutely no problem with the VARISORT M impurity separator - irrespective of the type of metal. Separates smallest metals starting from a diameter of 1 mm Separates wood-metal composites and pieces of wood with metal inclusions

VARISORT C - reliable separation of impurities The VARISORT C impurity separator is based on the principle of true-colour detection. It separates impurities such as rubber or plastics and two-side coated panel boards from the stream of hogged wood in fully automatic operation. Separates smallest impurity particles starting from a grain size of 5 mm Extremely low operating costs due to the use of conventional fluorescent tubes in the detection unit Auto-Learn mode automatically selects the optimum sorting parameters for good material and rejects

Reliable separation of metal particles and impurities from the stream of hogged wood

VARISORT MC - metal and impurity separation The VARISORT MC combi-system separates metals and impurities in one process step. The result is an optimally cleaned hogged wood fraction. Little space requirement due to common utilisation of conveyor and separating unit Easy integration in (already existing) production lines

Operator-friendly and future-oriented The menu-guided, self-explanatory Control Unit guarantees easy system operation. Because of the modular hardware design, the main components can be easily replaced by the operator, which drastically increases system availability. Other impurity separators currently under development can be subsequently integrated in the system. Control Unit of the VARISOFT C impurity separator

Functional principle of the VARISOFT MC

Metal detection On the high-speed conveyor belt (1) the stream of hogged wood (2) reaches the area of the metal detection coil (3) that is integrated in the conveyor belt. The HF multi-channel coil is segmented and therefore detects the metal contaminations with highest positional accuracy. Impurity detection By way of a chute at the end of the conveyor belt the stream of hogged wood is transported to the impurity detection area. The high-resolution CCD camera system (4) determines the exact position of the impurities.

Metal and impurity separation A blow-nozzle rail (5) is positioned immediately behind the impurity detection system. Via a separating shield (6) this rail separates the detected metal and impurity particles from the stream of hogged wood with minimum loss of good material. The information about exactly timed and positionally accurate separation of metals or impurities is supplied by microprocessors of the Control Unit as a link between the detection systems and the separating unit.
