Technical specifications

Separation range	2 µm – 120 µm
Classifying wheel diameter	20 mm
Classifying speed	max. 60,000 rpm
Total air volume	max. 20 Nm3/h

Principle of operation

Classification takes place according to the centrifugal counterflow principle in a rapidly rotating classifying wheel.
The powder is dosed into the viewing chamber and transported to the viewing wheel by the air flow.
Fine particles pass through the wheel, are discharged with the air and separated in a cyclone filter combination or in a filter.
Coarse particles are rejected by the classifying wheel and collected in a collection container.
The separating air is fed into the lower part of the housing via a paddle ring; this disperses the rejected coarse material and increases the separating efficiency of the separator.
The separating cut is adjusted by varying the gas volume and the classifier speed.

Technical specifications

Separation range	15 µm – 120 µm
Grinding to Mohs hardness	3.5
Classifying wheel diameter	20 mm
Grinding disc diameter	40 mm
Classifier speed	max. 60,000 rpm
Total air volume	approx. 20 Nm3/h

Principle of operation

Grinding is carried out by a rapidly rotating disc with grinding tools. The ground material is dosed into the grinding container and accelerated by the grinding rotor. Comminution is achieved by particle impact on the grinding tools of the rotor and by impact on the grinding track.
The grinding air flows from below through the grinding gap between the rotor and the grinding track and then through the classifier wheel located in the head of the mill.
Due to the classifying effect of the classifying wheel, fine particles can escape from the grinder with the air and are separated in a filter. Coarser particles fall back onto the rotor and are crushed further until they have reached the desired fineness.
The classifier mill is adjusted via the speeds of the grinding rotor and the classifier wheel as well as via the gas volume.

Principle of operation

The material to be ground is dosed into the centre of a rotor equipped with grinding tools and crushed by impact on the rotor and stator tools.
After passing through the grinding zone, the ground material enters the mill housing and exits the mill by gravity. The rotation creates an air flow from which the ground material is separated in a filter.
Different grinding tools can be used, e.g. rotor/stator discs with axial pins or a plate beater rotor with a profiled grinding path or with a sieve.
The fineness of the grinder is adjusted by the rotor speed and the feed rate.

Speed	2x max. 60,000 rpm

Principle of operation

The ground material is dosed into the centre of two counter-rotating pin discs and crushed by impact against the grinding pins.
The high shear rate of the counter-rotating discs enables particularly intensive stressing of the particles.
After passing through the grinding zone, the ground material enters the mill housing and exits the mill by gravity.
The rotation creates an air flow from which the ground material is separated in a filter.
The grinder is adjusted by the speed of the two rotors and the feed rate.

Technical specifications

Separation range	2 µm – 120 µm
Grinding to Mohs hardness	10
Classifying wheel diameter	20 mm
Grinding chamber diameter	40 mm
Classifier speed	max. 60,000 rpm
Total air volume	max. 20 Nm3/h

Principle of operation

The grinding energy is introduced by highly accelerated air jets via several grinding nozzles.
The ground material is dosed into the grinding container and fluidised by the air jets. The particles are accelerated by the air jets that meet at the focal point. Size reduction is achieved by particle impact at the focal point and by shear flows at the edges of the air jets.
The grinding air then flows through a classifying wheel located in the head of the mill, where classification takes place. Due to the classifying wheel with air, fine particles can escape from the grinder with the air and are separated in a filter. Coarser particles fall back into the fluidised bed and are crushed further until they have reached the desired fineness.
The fineness is set via the air volume, the grinding air pressure and the classifier wheel speed.

Grinding chamber diameter	33 mm
Grinding air volume	max. 4 Nm3/h
Propellant air volume	max. 1 Nm3/h
Grinding air pressure	2–9 bar O
Motive air pressure	2–9 bar O

Principle of operation

Several gas nozzles are used to generate a rapidly rotating vortex of air. The ground material is fed into the disc-shaped grinding chamber via an injector.
The comminution takes place through particle collisions caused by the velocity gradients in the air flow.
The grinding gas is discharged through an immersion tube located in the centre of the grinding chamber. The potential vortex flow creates a classifying effect so that only fine particles can leave the grinder through the immersion tube and are separated in a cyclone filter combination, cyclone or filter. Coarser particles remain in the grinding chamber until they have reached the desired fineness.
The grinding gas quantity, the grinding gas pressure and the throughput can be varied to set the degree of micronisation.

Technical specifications Picobond NOB

Process chamber volume	approx. 220 ml
Rotor drive	630 W
Rotor diameter	40 mm
Speed	max. 8,000 rpm

Principle of operation Picobond NOB

The powder mixture is completely centrifuged by the rotor and moves as a circulating ring layer along the inner wall of the mixer housing.
Stresses such as pressure, shear, impact and rebound are initiated within the compacted component fill in this ring layer.
On contact with the following rotor element, the direction of action of the transmitted pulse changes. This creates a complex, three-dimensional material circulation, which causes intensive, repeated pressure, impact, bounce and shear stress as well as intensive mixing of the material.
The high energy input into the mix compared to conventional mixing systems causes particle fusion, coating, agglomeration and particle rounding in addition to the basic operations such as macro and micro mixing.

Technical specifications Picobond AMS

Process chamber volume	approx. 190 ml
Rotor drive	630 W
Rotor diameter	40 mm
Speed	max. 7,300 rpm

Principle of operation Picobond AMS

The powder mixture is forced into the gap between the rotating rotor and the stationary stator, whereby the stress mechanisms of pressure and shear occur.
The formed edge layer is then separated from the inner surface of the rotor by a scraper and leaves the rotor through the side openings.
In the outer area, the blades attached to the rotor cause a return transport into the processing area.
This results in a permanent circulation of the material in the machine, which leads to the most homogeneous loading of the particle mixture possible.

Technical specifications

Useful volume	20–100 ml
Speed	max. 6,000 rpm

Principle of operation

The rotating mixing tool is arranged in a conical mixing container.
The special geometry of the mixing tool and the high shear rate ensure intensive, homogeneous and rapid mixing of the powder components.
The components to be mixed are filled into the mixing container and the machine is then closed.
After the mixing process, the container is removed from the machine and the finished mixture is emptied.
The mixing quality is set via the rotor speed, the mixing time and the filling quantity.
