Big Lump Grinder Machine Manufacturer

Big lump grinder plastic rigid lump waste heavy duty grinding shredding cutting machine manufacturer for lump in Ahmedabad, Gujarat, India

The Plastic waste Big lump grinder machine is a super heavy duty grinding machine specially designed for grinding big thick lumps produced in the plastic processing industry. This is a unique machine which converts big plastic lumps directly to small pieces in one single step. This eliminates the requirement of two different grinders to convert big lump to small pieces in two steps.

Plastic waste Big lump grinder machine specifications:

Drive system-

  • Drive via a pulley belt, reducing reverse-shock to the motor in heavy loads.
  • Way more efficient than a gear driven system.
  • Heavy rotor, pulley and flywheel for smoother and robust grinding.

Cutting system-

  • Dual sided heavy duty cutting blades for longer life and two time use. Once both sharp ends have worn off, the blades can be re-sharpened and re-used.
  • Very Heavy rotor with rotating blades. The stationary blades are adjustable and easy to remove for re-sharpening.
  • Roller bearings mounted in external MS housing separated from the grinding chamber for easy maintenance.
  • Quick blade change access for minimised downtime.

Grinder construction-

  • Very heavy rotor carries immense inertia and breaks the plastic lumps to pieces. This reduction in size is very quick.
  • Special type of blades for breaking toughest types of plastic lumps. Easy to re-sharp as well.
  • Heavy and robust MS body with precision cut spaces for smooth operation.
  • The body has very thick walls preventing any structural deformation under heavy loads.
  • Easy to re-sharp blades made out of hardened material for long life.
  • Auto load adjusted feeding conveyor (optional) for optimum output and reduced wear and tear
  • Easy to change screen for different output sizes.

Suitable for material types-

  • Any type of plastic lump of up to 30” in width and 5” thick and up to 3 feet long. (Throat size varies by model)
  • Jumbo Bags
  • Raffia bags
  • Injection / blow moulding articles

*Capacity Depend on Material & Feeding System

How the plastic Big lump grinder machine works:

  • The plastic big lump waste is fed from the throat at the top. If the piece is long, it is inserted vertically.
  • The material falls into the cutting chamber where the rotor (driven by an external motor and pulley system) has multiple blades on it.
  • The grinder body / chamber also has adjustable stationary blades. The distance between the rotating blades and these stationary blades can be varied (not during operation) according to different material types.
  • The material is cut at high speeds by a high inertia rotor. The solid rotor with special blades cracks the lumps into small pieces directly.
  • Below this is a screen with fixed hole sizes which only lets material of a certain size through, preventing any uncut material from leaving the chamber.
  • This screen can be changed according to requirements.
  • The output material is ejected at the bottom which can be optionally fed directly into a conveyor or air tube.
