Plastic Pelletizer
Used for recycling of the used and waste plastic PE, PP,HDPE, LDPE material.It also can pelletize the crushing material after fitting with a loader.Which can cut the material according to the feeding speed of the extruder.
Common range of waste plastics
StarsPlas plastic pelletizing machine is suitable for common waste plastics range from PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA and other plastic regeneration and color mixing granulation.

Key Components of Plastic Pelletizing Machines

The main parts of the plastic pelletizing machine are conveyor belt, cutter, compactor, shredder, extruder, pelletizer, cooling system, drying system and silo tank. With different internal screws systems, the machines can handle a variety of materials.

    Pelletizer FAQ

    After plastic hopper into the screw, under the action of the rotating screw, through the friction of the inner wall of the cylinder and the surface of the screw forward transmission, in the screw feeding section, loose solid material (or material at the end) is filled with the screw groove, with the continuous transmission of material, material began to be compacted. When the material enters the compression section, the depth of the screw groove gradually becomes shallow and the resistance of the head makes the plastic gradually form high pressure, and is further compacted. At the same time, under the action of the external heating of the cylinder and the internal friction shear heat generated by the strong stirring, mixing and shear friction of the screw and the inner surface of the cylinder, the temperature of the plastic is rising continuously. At a certain point in contact with the cylinder, the temperature of the plastic reaches the melting point and begins to melt. With the conveying of the material, continue to heat, the amount of molten material gradually increased, and the non-molten material record a corresponding reduction. About the end of the compression section, all materials are transformed into viscous flow state, but at this time the temperature of each point is not uniform, after the homogenization of the homogenization section is more uniform, the screw will be quantitative, constant pressure, constant temperature squeezing into the machine head. Machine head die is a forming part, the material through it to obtain the geometry and size of the section, and then after cooling and other processes, you can get a good product.

    1. Suitalbe for HDPE,LDPE,LLDPE and PP.
    2. Equipped with the vertical and horizontal force-feeding device to ensure high output.
    3. Vent design on the barrel to evaporate the volatiles form the recyle maerial.
    4. Hydraulic screen change unit and pressure gauge for easy operation and safety.
    5. Water chamber with die face cutter simplifes the process.
    6. The vertical centrifuge separates and dry the pellets faster.
    7. High-efficient force-feeder ensures high capacity feeding, low energy consumption
    8. Plastic pelletizer style: water-ring cutting with extrusion mould, even cutting ensures good shape.

    Any unrelated personnel are not allowed to talk to the operator of plastic recycling extruder equipment. The button commands on the electrical control panel are for one person only.
    Regularly check the insulation effect of the line, and always pay attention to the warning content on the warning sign of the machine;
    Before the power distribution cabinet is powered off, it is strictly forbidden for non-professionals to open the door of the cabinet, and it is strictly forbidden to adjust the cutter before the granulator is completely stationary.
    When the moving parts and hopper are blocked, do not use hands or iron rods, only use plastic rods to carry them carefully;
    Be careful of burns when touching hot parts. When the kneader is working, it is strictly forbidden for the staff to extend their upper body into the cylinder to inspect or scrape the materials.
    During the working process, if a power failure occurs, the motor circuit should be cut off, and the memory materials of the machine should be cleaned up in time. Carbonization of materials will affect the next step of production.
    When the machine breaks down, the machine should be stopped as soon as possible, and self-assertion is not allowed. And notify and wait for maintenance personnel to investigate maintenance or telephone maintenance guidance;
    Eliminate all factors that cause machine damage and industrial accidents; operate in strict accordance with standard operating methods to reduce failures or accidents.

    Feeding materials onto the Belt Conveyor –materials being pre-heated, cut, mixed and compacted in the Cutter Compactor machine – being squeezed evenly in the Extruder – coming out from the machine head after venting and filtering system Hydraulic screen changer –being cut by pelletizing sytem –being dried by Dewatering system – being trasnferred into the Silo –the end.

    Working principle: After the plastic enters the screw from the hopper, under the action of the rotating screw, it is conveyed forward through the friction between the inner wall of the barrel and the surface of the screw. In the feeding section of the screw, the loose solid pellets (or powder) fill the screw groove. , as the material is continuously conveyed, the material begins to be compacted. When the material enters the compression section, due to the gradual shallowing of the groove depth of the screw and the resistance of the machine head, the plastic gradually forms a high pressure and is further compacted. At the same time, under the action of the external heating of the barrel and the internal friction and shear heat generated by the strong stirring, mixing and shearing friction between the screw and the inner surface of the barrel, the temperature of the plastic continues to rise, and the plastic is in contact with the barrel. At a certain point, the temperature of the plastic reaches the melting point and begins to melt. As the material is conveyed and continues to be heated, the amount of molten material will gradually increase, while the volume of unmelted material will decrease accordingly. At about the end of the compression section, all the materials are transformed into a viscous flow state, but at this time the temperature at each point is not uniform, and the homogenization effect of the homogenization section is relatively uniform, and then the screw will quantitatively, constant pressure, and constant temperature of the molten material squeeze into the machine head. The die in the machine head is a forming part, through which the material obtains the geometric shape and size of the section, and then after cooling and shaping and other processes, the formed product can be obtained.

    1. Pay attention to the temperature change of the fuselage at any time. When touching the sliver with clean hands, the temperature should be raised immediately. It is normal until the strip sticks to your hands.
    2. When the bearing part of the reducer is burned, or accompanied by noise, it should be stopped and repaired in time, and refueling should be added.
    3. When the bearing parts at both ends of the bearing chamber of the main engine are hot or there are noises, stop the machine for inspection and add butter. During normal operation, the bearing chamber is filled with butter every 5-6 days.
    4. Pay attention to find out the operation rules of the machine; for example: the temperature of the machine is high or low, the speed of the speed is slow, and it can be dealt with in time according to the situation.
    5. When the fuselage is running unstable, you should pay attention to check whether the coupling gap is too tight, and loosen it in time.
