The hottest KP series two-stage twin-screw single

KP series two-stage twin-screw/single-screw extruder

the two-stage extruder is composed of a twin-screw mixer, a single-screw extruder and a grinding and pelletizer. It is suitable for mixing, extrusion and granulation of hard (soft) PVC, XLPE and other heat sensitive and shear properties. Its characteristic is to give play to the respective advantages of twin-screw and single screw; In twin-screw mixing, materials are uniformly mixed by mixing and shearing elements; In the single screw extruder, the material is extruded by the slowly rotating screw to avoid the shear heat of material production. The temperature of each section is optimally controlled to prevent the degradation of heat sensitive and shear materials. It has the characteristics of low energy consumption, high output and stable product quality

structural features of the equipment:

twin screw mixer:

1. The barrel machine and screw adopt "building block" structure, full meshing screw, with strong self-cleaning performance. The cylinder and screw components are made of 38GrMoALA, which is nitrided and has good wear resistance

2. The cylinder adopts electric heating, water cooling, imported conductive or RKC intelligent temperature control instrument, two-way PID regulation, CKD solenoid valve for temperature control, and adopts precision CNC engraving to process polycarbonate, with high precision temperature control

3. It adopts specially designed transmission device, imported bearings, precision gear processing, stable transmission and high transmission torque

4. Adopt silicon controlled rectifier, DC motor speed regulation, or AC motor speed regulation with frequency converter

5. The feeding device is composed of a hopper with mixer, a horizontal metering feeding screw and a vertical forced feeding device, but this local oil pressure is not used for sample loading, and a liquid auxiliary injection port is set in the appropriate parts

6. According to the needs of users, multi-channel electronic metering and feeding system or continuous electronic metering and feeding system can also be configured

single screw extruder:

1. Hollow equidistant and unequal depth screws are used, and the temperature of the screw center is controlled by a water cooling device. The screw and barrel materials are 38GrMoALA, which are nitrided and have good wear resistance

2. The cylinder adopts electric heating, water cooling, imported conductive or RKC intelligent temperature control instrument, two-way PID regulation, CKD solenoid valve for temperature control, and the temperature control is precise and high

3. The specially designed transmission device adopts imported large thrust bearings

4. Adopt silicon controlled rectifier, DC motor speed regulation or AC motor speed regulation with frequency converter

5. The head is equipped with a pressure sensor to measure the head pressure and the melt temperature

transition body: the twin-screw and single screw transition bodies are cross connected up and down, and there are vacuum openings and lighting devices above the transition body, and there are visual windows on the hinged door to observe the material situation

grinding and pelletizing machine: materials are extruded in strips from the head template and cut into particles by the pelletizing machine. The particle length can be controlled by adjusting the knife rotation speed

the equipment adopts lock control, with mechanical and electrical double overload protection. The control cabinet is equipped with analog display diagram board, and the rotation of each part of the unit is visually and clearly displayed

the following control modes can be selected for electrical control according to the needs of users:

1. Type I - programmable controller, thyristor DC speed regulation

2, type II - deviation controller, VVVF AC variable frequency speed regulation

3, type III - microcomputer control, VVVF AC variable frequency speed regulation
