MAS Series - Beside-the-Press Granulators
The MAS Series (MAS1 to MAS4) has been developed specifically for the in-line recycling of soft to medium hard plastics.
- The very compact design allows MAS granulators to be used directly beside the injection molding machine
- The granulators can be easily adjusted to suit the individual application.
- Special hopper design for tangential feeding
- High quality regrind due to low rotor speed (200 rpm)
- Fastest change of knives without using pre-adjustment gauge (MAS1, MAS3)
- Standard pre-adjustment gauge for fast and easy change of knives (MAS2, MAS4)
- Moving and fixed knives can be sharpened.
- Patented tensing clamps of the rotor knives ensure fast and safe change of knives.
- Pre-equipped with electrical cabinet to receive all electrical options later on.
- Regrind collection bin allows manual emptying or vacuum evacuation.
- The hopper and regrind evacuation bin, which are in contact with the regrind materials, are made from stainless steel (standard).
Rugged Design for Continuous Operation
Cutting Chamber
- Rugged bolted steel construction
- Double supported bearing of the shaft for vibration free operation
- Open rotor with 3 moving and 2 fixed knives
- Replaceable inserts on the side walls of the cutting chamber prevent wear of the walls that could arise from rotating part and sprues
- Easy change of the screen by means of tensing clamps
- Using both sides of the screen results in an even longer lifetime
Motor Drive
All MAS models are driven directly via a gear motor and equipped with double bearing rotors and flywheel (MAS3/MAS4 standard).
Hopper
Designed for all kinds of feeding
Soundproofed hopper with large chute opening and anti-flyback curtain
Material Extraction
Regrind collection bin allows manual emptying or vacuum evacuation.
Electrical Equipment And Safety
- Electric cabinet integrated into the granulator allows adding options later.
- Safety system to open the granulator by safety switch
- All MAS granulators meet the specifications of the EN12012 standard.
Sound Level
Less than 80 dB(A) sound level (depending on material and feeding of granulator)
Easy Cleaning
- The design of the granulators allows easy cleaning and reduces downtime to a minimum.
- Quick access to the cutting chamber and screen without requiring any additional tools.
Options
- Flywheels (MAS1/MAS2)
- Level indicators providing visual/audible alarm
- Water cooling (MAS2, MAS3, MAS4)
- Soundproofed execution (MAS2, MAS3)
- Higher frame for bagging (MAS1, MAS2)
- Rotating evacuation bin (180 °)
- Evacuation bins for manual evacuation
- Various screens available
- Wear protection of the cutting chamber
- Phase detector allows to check the direction of rotation (MAS2, MAS3, MAS4).
