CRT EXTRUDER SHREDDER

CRT Extruder Shredder is the state of art technology of Shredding and Granulating of industrial waste plastics. Simple operation, intelligent control system and automatic operation leads to minimum operator requirement and cost benefit.  

All forms (lumps, rolls, loose film, baled film etc.) of LDPE, LLDPE, MDPE, HDPE, PP, PS, ABS can be granulated by CRT Extruder Densifier. Industrial wastes, which must be shred before Extrusion, are granulated at a single step by a single machine thanks to the integrated automatic Shredding system.

Thanks to the superior technologies of CRT Extruder Shredder;

  • Shredding,
  • Plasticising,
  • Degassing,

are done at Single Step.

 

Intelligent control system allows Autonomous Operation which means no operator is required to run the machine. All parameters that is required to run the machine can be saved as different receipts according to the type and form of plastic to be granulated, while switching to different plastics parameters is chosen and downloaded to the machine by a Single Button.

CRT Extruder Shredder follows the capacity according to system parameters and automatically intakes required raw material to Shredding chamber. Plastics are pressed on the rotor automatically according to receipt by hydraulic powered pusher. Rotating blades on the shredder rotor and the fixed blades which are mounted on the shredding chamber shred the scrap till the plastics are downsized enough to pass the screen holes. Size reduced plastics are fed into the Extruder screw automatically according to receipt by hydraulic powered pusher. Type of pusher is chosen according to the form of plastic to be recycled.

High degassing and suction efficiency thanks to Extruder screw design with twin degassing zones and powerful vacuum pump. Liquid ring vacuum pump made of AISI316 stainless steel is used, sucked gas is mixed with water by the vacuum pump and discharged. Condensation tank made of AISI304 stainless steel with cooling layer is used to circulate the water which is required by the vacuum pump. 1 – 1.2 m3/h water is saved by the condensation tank.

Power transmission between Extruder motor and Gearbox is realized by steel spring coupling and this saves energy comparing to belt driven systems. Extruder motor and Shredder motor are both controlled by individual inverters. IE3 energy efficient class motors are used for high energy efficiency.
