The new pelletising process with an established track record. The Hydropellet flat-matrix press HP 500 introduces pioneering innovations for automatic pelletising/granulation in production facilities with a wide range of materials. For a uniform dosage of the material, the self-developed round silo with discharge cone and seamless discharge screw is used with frequency and performance controlled output.

The technical data: Drive motor 30/37 KW Hydraulic drive unit Matrixes diameter 600mm Crimping diameter 250 mm Matrix aperture diameter 4-16 mm Width of the mat: Working width/Spreading width (281/445mm) Throughput - 500 kg/h input (bulk density and pellet diameter dependent) Weight approx. 1800 kg

Automatic distance adjustment

The automatic distance adjustment of the roller wheels to the matrix surface enables the material to be transferred, the friction process (with heat factor) to be compacted from the matrix holes and the quality of the pellets to be changed during operation.


This frictional displacement makes it possible to save moulds significantly by eliminating the need for a suitable pellet quality.


With the automatic distance adjustment, a granulating process can be performed, which produces a homogeneous final granulate from various input granules, a factor which is important for pellet and granule quality.


Due to the friction conditions, material decompositions of composite materials are made possible which are otherwise hard to achieve. The latter process takes place predominantly with short matrix apertures of 10-16 mm.


Automatic speed control of the skidders. The speed of the skid wheels is automatically controlled synchronously with the load. And takes place in 2 stages.

- First stage for cold starts.

- Second stage takes place according to the time, pressure, and temperature specification.


Recipe preselection for a specified PELLET quality

Recipes allow for a variable material distribution between the crimping wheels and variable material strokes in the matrix and ensure continuous pellet quality.


The prescription/specification of the material/discharge speed from the dosing silo - the default value of the contact pressure of the collars in relation to the material quantity and rotation specification of the crimping head with the crimping wheels.

- Distance adjustment between the crimping wheels and the matrix surface, the friction conditions can be influenced by this.


The matrix cooler

Thus, when the temperature is exceeded, a cooling with an adjustable range and a normal water connection of the matrix is automatically switched on, and if the material pressure between the roller and the matrix e.g. for wood, paper and biowaste does not fall to the correct pressure, a liquid/water spray device with an adjustable dosage can be automatically switched on.



- Connection of the matrix cooling device according to the temperature specification range

- Connection of water mist spraying device


Pellet length

An adjustable stroke speed of the stroke device is used to determine the pellet length.


Functional monitoring

Automatic functional monitoring with oil cooling, overload protection with soft start, including reversing control of the crimp head, is standard. The connection to the dosage-controlled round silo with controlled discharge screw is performed by means of an electric pre-installed plug-coupling connection.


The basic equipment

The machine is equipped with all the options to make the most versatile use of wood, paper, plastic, textile, fibres and fabrics as well as foams and compounds of all kinds.


The machine is equipped as standard with 30 KW drive motor for flexible electric plug connection and with transport frame for semi-mobile installation.


Plant areas with crushing dosage and pelletising for microfiber bales have now also been achieved with this technology as well as the pelletising of spice and wood chips.


NEW: Carbon fibre pelletising with fibre structure retention.
