Main features of extruder

Closely inter meshing screw profile with screws that are self-wiping at narrow clearance for easy product and color changing.

Special mixing and shearing elements is with varying effects for high process flexibility.

Modular building-block system for barrel.

Each barrel is with one temperature zone for optimal processing.

High reliable safety clutch and interlocking system for optimal protection against overload

High torque gear box ensure high output and long life time.

Variable screw speed from 100 to 800 rpm allows wide range of process technologies.

Large free volume due to outer/inner screw diameter ratio Do/Di ~ 1.75 for optimum processing.

Water manifold completely made of stainless steel.

Technical Specifications

Main motor:

Supplier: WN/ Huabin

AC motor, 315 kW

Speed controller: Siemens AC inverter.

The clutch is used to transmit the power from the motor to the gearbox.

High safety coupling with torque limit from Polytec.

With cover for safety.

High torque gearbox:

Precise balancing principle applied to increase torque level.

Torque level up to 10.3 defined by Torque/center line distance.

High safety factor design.

Latest steel alloy material for gears applied with special heat treatment and manufactured at high precision level.

NSK bearings and imported seals applied,

Special lubricating for gearbox:

Fin-plate heat exchanger configured to provide best cooling.

With one temperature sensor: if the oil temperature more than 60 degree, the extruder will stop automatically.

With one pressure sensor: if the oil pressure less than 0.2 MPA, the extruder will stop automatically.

With one pressure indicator meter for the operator to see the pressure easily.

With magnetic filter to remove the metal power from the gear.

With one vane pump with much less noise compare to the traditional gear pump.

Screw element & shaft:

The intermeshing screws co-rotate and wipe each other with narrow clearance so that no residues are left in the screw flights and cleaning effort is thus reduced.

The screw shaft system is characterized by the following:

Through-going solid shafts

Screw elements with various pitches and lengths

Kneading blocks with various angles of stagger, numbers of kneading disks and disk widths

Screw tips to fix the screw set axially

Gear teeth connection to ensure power flow between the screw shaft and screw elements

Screw Diameter: 95mm. L/D = 40:1.

Maximum Screw speed: 300rpm.

Screw configuration: with modular structure, torque transmission by spline.

Material of screw: 38CrMoAlA.

Nitrify treatment: with nitrify depth 0.4～0.6mm.

Surface hardness: HV740～940.

Roughness: Ra≤1.6µm.

Structure feature: modular fixed on shafts.

Direction of screw: co-rotating.

Screw shaft material: 40CrNiMoA.

The flexible modular principle is realized with barrel sections from the wide range of different designs possible. Fast, intensive and uniform heating of the barrel sections is ensured by electrical heaters. The barrel sections are cooled with water, by means of an internal bore system, with bores arranged close to the inside barrel wall.

Barrel sections are available as:

Closed barrel section

Barrel section with opening for material feed or devolatilization

Barrel section with top and lateral opening for top venting .

The processing section is provided with stainless steel plates as a protection against accidental contact.

Barrel configuration: with modular structure, each one with length of 4L/D, and the barrels connected together by bolts and pins.

Material: 38CrMoAlA.

Nitrify treatment:

Nitrify depth of screw: 0.5～0.7mm.

Surface hardness: >HV940.

Roughness: Ra≤3.2µm.

Temperature control system:

Temperature controller: PLC.

All of barrel with heating and cooling both, except No.1 barrel without heating, only with cooling channel.

Heating system: infrared heater, total heating power with about 90KW.

The system consists of:

1water-pump (3KW)

1 stainless steel water-box (with water Temp. gauge)

1 fin-plate heat exchanger

1 water pressure indicator

1 solenoid valve for each barrel

1 manual valve for each barrel

Consisting of following main components:

Motor:11 kw*2, Pumping speed:150L/m

2 force vacuum exhaust port

Rotating speed:2900, rpm Pressure :133Pa.

1 manual valve

1 air pressure indicator

1 bypass

With independent PLC and HMI control.

- After all machines are delivered to customer’s factory; Buyer is responsible for all preparation work, e.g. electricity supply, water supply, labors and cranes, etc.

- oem will prepare for visa application for their engineers, who are responsible for guide of machine installation and testing at the Buyer’s factory to meet normal operation requirements.

- The Buyer will buy the round-trip air ticket for Engineer if visa application is approved. The buyer is also responsible to bear expenses generated, e.g. visa formalities, meals, accommodation, and allowance of USD200 per day for each engineer from the date of departure to the end of the trip (including round trip time).

- Engineer will give free training lessons to labors in buyer’s factory.
