NEW Pelletizer HP500 (patent pend.)

BP-Recyclingsystems GmbH is the latest development of a flat die pelleting press from BP-Recyclingsystems GmbH formerly known as Holzmag. The new pelletizing technology of the HP500 series includes die cooling and automatic contact pressure control. Developed for the processing of glass fiber and PVC chips.

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.

autom. distance adjustment

The automatic distance adjustment of the pan grinder impellers to the die surface enables the material friction process (with heat factor) to be shifted from the die bores to the pan grinder chamber for compaction and makes it possible to change the quality of the pellets during operation.

This friction shift enables significant die savings by eliminating the need for adjusted die thicknesses for a fixed 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.

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.

Die cooling
If the temperature specification is exceeded, cooling with an adjustable range and normal water connection to the die is automatically switched on, and if the material pressure between the pan grinder and die does not drop to the specified pressure, e.g. with wood, paper and biowaste, a liquid/water spray device with adjustable dosage is automatically switched on.

Cooling

- 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.
