Automatic Plastic Pellet Machine, Color : Light White

1. Extruder Base:

The base us fabricated out of mild steel plates, Channels, The Top of the base

is machined to mount hopper block and barrel support bracket. The AC

induction motor and Helical Gearbox are accommodated on the base

2. Screw & Barrel:

The screw and barrel are made from special alloy steel. Barrel and screw are

nitride hardened, fine polished and chrome plated. The function of the screw

is to carry the material from hopper to die with homogeneous melt. For

precise control of temperature, the barrel is divided in to equivalent zones.

Thermocouples fitted on the barrel and Pyrometers on control panel are for

monitoring and controlling of the temperatures in each zone. Die zone is

mounted on die head for precise control of temperature of die head. Watercooling

jacket is provided in hopper block. Water circulation in the jacket is

necessary, for the safety of thrust bearings.

3. In built Thrust housing helical gear box:

It is constructed robustly from cast iron to hold the barrel horizontal. Barrel is

fitted with heavy flange with high-tension bolt. It is having six bearings. One

additional bearing is to withstand thrust pressure during extrusion. Seals are

provided for restricting the entry of raw material in the gear box bearing

housing. All Bearings are standard Make.

4. Main Drive:

Ac motor with heavy-duty gearbox connected through housing and sturdy

coupling.
