Mixing Mechanism (LCM)


Pelletizing Mechanism

Mixer Mechanism (LCM Series)

High Reliability

Both Ends Supported Rotor
The two rotors have a construction whereby they are supported at both ends with bearings to enable high-speed operation in a very stable condition. The both-ends supported design eliminates the possibility of metal contact between the rotors, and between the rotors and the chamber. Moreover, to withstand the high pressure generated by the mixing action, the mixing section has a special triangular shape to optimize strength and mixing performance.
Highly Powerful Gear Reducer
A highly powerful gear reducer has been developed to meet the ever-increasing demand for larger polymer production capacity.
Sealing Mechanism
The drive end dust stops and water end visco seals are designed to prevent powder and molten polymer leakage and to make maintenance quicker and easier.

Characteristics of Each Section

Feed Section
The diameter of the feed screws is larger than that of the mixing section, making it easier to convey low bulk density materials and eliminate feed-neck problems. In addition, the counter-rotating screws are excellent in homogeneously blending materials that are fed separately.

LCM Mixing Mchanism
Mixing Section
The cross-sections of the rotors in the mixing section have a special triangular shape, providing tip clearance between the rotors and the chamber wall at six points. In addition, the mixing wings have axially continuous rotor tips, allowing the polymer to repeatedly pass through the tip clearances. It is this repeated passing of the polymer through the tip clearances that provides the high shear strain necessary for effective melting and thorough mixing. Hence, Kobe Steel's rich design experience makes it possible to select the rotor shape most appropriate for melt homogenization and additive dispersion.
Gate Section (Patented)
Adjustment of the circular clearance between the gate and the rotors by vertical movement of the gate allows control of the material filling ratio and residence time in the mixing chamber, making it possible to easily regulate the energy input to the material. This structure enables easy control over a wide range of mixing conditions and over a wide range of resin temperature.

Mixing Mechanism

Gear Pump (KNT Series)

Low Energy Consumption
The Kobe design gear pump raises the melt pressure with minimum power consumption and without increasing resin temperature. The gear pump has a high efficiency, good reliability and excellent metering performance.
Mixing Control through Suction pressure
The filling ratio of the second mixing section, namely the residence time, can be controlled by adjusting the gear pump speed which in turn regulates the suction pressure of the gear pump. Combination of this function together with LCM gate mechanism and two stage mixing rotors provides a wide range of mixing control.

Dual Type Screen Changer (KSD Series)


Dual Type Screen Changer
Easy Maintenance
Dual passage of the polymer through the twin bars means that screen changing may be done safely at low speed and without interruption to production. Moreover, once the screen pack has been replaced there is no need for cleaning of the breaker plate.
Low Pressure Loss
A split, curved, breaker plate design with a large open-area ratio helps to reduce pressure losses and increase screen-pack life (Patented)
 

Pelletizer (UP-N Series)

Automatic knife Pressing System
The 'pushing force' of the pelletizer knives against the die-plate is controlled automatically and may be adjusted simply according to polymer type. Thus making it easier to produce pellets of uniform geometry.

Die Plate
Cutter-Shaft Fixing System (Patented)
A cutter-shaft fixing system, which maintains the cutter-shaft position after setting the knife to the die-plate at an appropriate pressure, helps to reduce knife wear. In addition, the drive system having an extremely low vibration structure stabilized the cutter shaft rotation to provide good cutting quality.
Die Plate
Kobe can provide titanium carbide type die plate and tungsten carbide (WC) type die plate. Both of the Kobe developed die plates have excellent wear resistance, and high efficient heating with heat channel.
Good alignment of Knives and Die Plate
Drive housing is connected to the front flange of the Water chamber with four tie rods. Cooling water is supplied to the four tie rods so that temperature of the tie rods is kept uniform. The alignment of knives and Die plate is kept at a constant condition, because thermal deformation of water chamber is minimized.
Quick Clamp System
The water chamber and the die-plate can be connected and disconnected by automatic quick-clamps. These allow easy and quick operation during both start-up and maintenance procedures.
