Series MC
For Medium to Large Throughputs

Series MC

Heavy duty granulators. They are intended for recycling beside the IMM (MC 34) and/or for centralized recycling (MC 46/MC 70) of runners, parts and various scrap. The MC Series product range consists of 6 models. The granulators
of the MC range are compact and general-purpose granulators for medium to large throughputs.

Main features:

  • Tangential feed cutting chamber for optimal acceptance of parts.
  • Very good regrind quality due to reduced rotor speed (according to model 430 to 730 rpm).
  • Quick and easy knife maintenance with
  • pre-adjustable knifes that can be sharpened.

Advanced soundproofing.

  • Herringbone rotor
  • Fitted with 3 or 5 blades (depending on the model and /or application)

Rugged, High Performance Design

Cutting Chamber

  • Solid steel welded construction.
  • Screen with standard hole diameters from 6 to 12 mm according to model and application, mounted on screen support, opened via gas or hydraulic cylinder (according to model).
  • Replaceable wear plate on attack side in standard configuration.

Rotor

  • Herringbone rotor supported on 2 heavy-duty outboard pillow block bearings. Fitted with 3 or 5 blades.
  • Mechanical brake.

Blades

  • Made of high alloy hardened steel; can be sharpened several times.
  • All blades are pre-adjustable using a pre-adjustment fixture supplied as standard, which simplifies installation and guarantees constant cutting circle and thus consistent regrind quality.
  • Scissor style cutting for low energy consumption.

Drive

  • Rotor driven by pulley and belt.
  • Inertia flywheel in standard configuration.

Electrical Equipment

  • Separate electrical control cabinet with star delta soft start (MC 46-60 and larger).

Feeding

  • Soundproofed feed hopper can be easily adapted for all types of feed methods – robot, conveyor or manual.
  • Hopper opening assisted by cylinders (manual, electrical or hydraulic handling depending on the model).

Emptying

  • All regrind collection bins are prepared for blower evacuation.
  • Manual evacuation (collection bin with viewing window) available on request
    (depending on the model).

Sound Control

  • Models MC 34 and MC 46 are supplied with integrated and optimal soundproofing.
