PP PE PS sheet production line

PP PE PS sheet production line
Product Detailed
1>low rotation speed,hight output 2>good plastify efficiency 3>special screw for PP/PE

The combination of both in-house testing and feedback of “in-service” machines has allowed LJC to develop extruders that both maximise machine efficiency and suit customer requirements. The original LJC extruders screw design for various materials ( PP-PS-PET-ABS-Multilayer) has been extensively tested and is constantly upgraded to fit the raw materials improvements, to achieve optimum quality and throughput.

LJC EXTRUDERS can be supplied in a range from 45 mm to 150 mm, with air or water cooling system. The L/D ( length/diameter) ratio is from 30/1 to 35/1.The barrel supply collar has, on the inside, a cooling circuit at controlled temperature. Cooling of extruder cylinder in the water-cooled models is by an independent central unit, while cooling of extruder cylinder in the air-cooled models is by motor-ventilators for each single control zone. The number of control zones ranges from 4 to 7 according to the model and their temperature is controlled by a computerized LJC system.

The screw thrust has an axial roll-bearing and abundantly dimensioned rolls.The connection between motor and  gear is direct, through an elastic joint, suitable for absorbing bumps and vibrations.

The extruder barrel is made by two-metal alloy; in the smaller models (D45-D65-D80), is made by nitrided steel as standard, by two-metal alloy as optional.  The gear , the barrel and the motor are installed in a single structure, solidly made of electro-welded pieces. Special covers in stainless steel , easily removable, protect the heater cylinder zones.

THE EXTRUDER MOTOR is AC or DC, complete with motor-ventilator. The extruder motor is placed under the barrel to reduce overall dimensions, while the motor drive, variable speed and constant torque, is included in the general control panel of the extruder. The venting plant is made up of: liquid ring, vacuum pump, flowmeter for pump protection. A water-reclaiming  system can be optionally supplied.
