Low speed screenless granulators – rotor speed 27 rpm. Designed to process hard plastic materials from injection molding machines. Beside-the-press granulator for feeding by hand or robot.

Advantages of Screenless Granulators

• Low speed technology reduces wear of cutting chamber components, knives, rollers and combs.
• Reduced heating of material: no deterioration of the plastic molecular structure.
• Reduced dust: Very few fines.
• Energy efficient.
• Quiet operation.
• Easy use and cleaning: knives and rollers
  can be disassembled for sharpening.

Proven Quality for Injection Molding Plants

Cutting Chamber

• Reversible knives, combs and counter combs provide double lifetime.
• Treated and knives, rollers and combs can be sharpened.
• Rollers with helical configuration for staggered cut.
• Various cutter sizes and shapes to suit the application.
• Double opening.

Hopper

• Designed for all types of feeding.
• Hopper with large opening.
• Top feed chute, viewing window and anti-reject curtains.

Material Extraction

• Regrind collection bin supplied as a standard in stainless steel for optimum regrind quality.

Electrical Equipment and Safety

• Electrical cabinet with “On/Off” push button with “Emergency Stop”.
• Two safety switches on hopper and regrind collection bin.
• Corresponding to CE standards.

Sound Level

• Less than 80 dB (A) (depending on material and throughput rates).

Options (All SUMO Range)

• Automatic reversing system (ARS).
• High level detector.
• Higher base for larger capacity collection bin and/or 360° swivel outlet.
• Motor power.
• Different hopper designs.
• Water cooling system.
• Surface treatment of cutting chamber components for wear resistance.
   

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 tool

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).
