Compounding and Granulating Plant

Product Details

Our Compounding and Granulating machine has state of art technology in either of following form
- Two stage compounding including die face cutting, pallet cooling and pallet conveying .
- Single stage compounding with vent, die face cutting, pallet cooling and pallet conveying.

For the granulating of soft PVC, rigid PVC, ABS etc and their modification and as well as for the heat sensitive polymers, both of the above technologies are capable enough to provide the customer with following benefits:
- Uniformity in granule size
- Lower dust or very fine particles contents.
- Good surface structure blister free granules

Extruder: The Extruder is a Sturdy Machine in which the Gear unit is provided with helical gears that are case hardened and grounded. Thus, ensuring uniform power transmission and low noise operation. The Axial Thrust of the Screw is absorbed by a self aligning Thrust roller Bearing rated for high thrust load and a long service life. The bearing is arranged in separate housing being flanged to gear box unit.

Barrel: Barrels are made of nitride steel. For better control and homogeneity, the Barrel is divided into different zones and temperature of each zone is regulated by heater and cooling blowers.

Screw: The relevant Screw geometry is adapted to the relevant process task. They are generally made up of nitride steel. Through the special construction of Screw and Barrel, high shear force and high shear speed can be achieved in the melts, which helps getting excellent homogenization of material. The heat thus generated can be dissipated on to barrel walls so that no undue temperature increase takes place which in turn leads to process optimization, high output and desired granule size and at the same time maintaining the required level of plastification.

Extrusion Process: For a faultless and uniform distribution of plastified material in the area of screen plate, the Screw geometry, the die inlet and die bore are optimized from the Reheological point of view, so that there cannot occur any thermic damage of product in the region. The design is based on the concept of a very low velocity of extrusion through each hole, in order have low head pressure. This means a thin pellet plate, which also keeps the pressures low. The low pressure in the head (30-50 bars) allows better control of the polymer's temperature.

Cutting Process: The blades are placed on blade holders in the combination of 2 and 4 which can be positioned individually towards the die plate via adjusting bolts. The adoption of the granulator length is effected via a step less adjustable AC drive, which is directly coupled to blade holder. The blades are made of high tensile and wear resistance steel ensuring long service life.

Cooling and Conveying: For collecting the granules, the cutting system is attached with the pneumatic conveying system which conveys the granules to the granule cooler. The hot granules are cooled by Air and the cooling intensity can be controlled by controlling the Airflow. Afterwards it is flown to vibrating chutes where the flow of air swirls around the granules and the final output is than poured into the open tub or directly into sacks.
