Makes short work of shredding:

Cost-efficient, highly reliable and only one step.

Nothing can withstand the enormous power of the Lindner Polaris single-shaft shredder. Made for one-step processing of untreated municipal, industrial and commercial waste to obtain mid-calorific fuels (40 - 120 mm) ideal for co-incineration in calciners at cement works. Sturdy design and low operating costs are the hallmarks of this highly specialised shredder: enjoy uninterrupted shredding excellence 24 hours a day, seven days a week. With maximum efficiency throughout, as demonstrated by a field test: thanks to the countershaft drive, the Lindner Polaris shreds twice as much material as comparable machines in the same period of time.*

1 | Internal pusher

Lindner's original: tried and tested a thousand times over, our internal pusher allows for easy and secure machine feeding. Our years of experience and continuous development have left their mark on its distinctive design.

  • CONTINUOUS SHREDDING due to smooth feeding
  • DELIGHTFULLY MAINTENANCE-FREE thanks to the absence of guide elements
  • EASY FEEDING with a completely internal construction
  • NO JAMMING as a result of additional comb and sealing bars

2 | Countershaft drive

COUNTERSHAFT DRIVE WITH FLYWHEEL ENERGY STORAGE

Less energy consumption and more power thanks to the countershaft drive that stores and releases rotational energy depending on the load.

  • MAXIMUM ENERGY EFFICIENCY
  • UP TO 2x MORE THROUGHPUT compared to drives without higher flywheel mass*
  • WORLDWIDE AVAILABILITY of spare parts

3 | Plug & go screen unit

The swivel-mounted, hydraulically operated screen unit allows for easy and comfortable access for maintenance and refitting. The screens are available with various mesh widths and can easily be changed by hand by just one person – so you can quickly customise the shredder to the particle size you need.

  • FLEXIBLE OUTPUT SIZES made possible with screen units in various hole sizes
  • EXTREMELY SAFE OPERATION thanks to the electromagnetically locked screen access point, preventing access to the cutting system while the machine is in operation
  • EASY ACCESS FOR MAINTENANCE AND FITTING due to the swivel-mounted, hydraulically operated design

4 | Safety clutch

The torque-limiting clutch protects against damage to the drive unit when blockages are caused by foreign objects. Furthermore, the highly precise sensors facilitate the controlled powering down of the machine to preserve all components.

  • PERFECT DRIVE PROTECTION thanks to the drive unit’s instant mechanical disengagement
  • SECURE POWER DOWN with sturdy sensors
  • FULLY ADJUSTABLE to your materials

5 | Maintenance door

The hydraulically operated, inward-opening maintenance door allows you to quickly and safely access the cutting system for maintenance work or swiftly remove foreign objects with minimum material leaks.

  • REMOVE NON-SHREDDABLES QUICKLY AND CLEANLY with the maintenance door at position 2
  • ENJOY CONVENIENT MAINTENANCE ACCESS TO THE CUTTING CHAMBER with the maintenance door at position 3
  • 100% SAFE OPERATION thanks to the mechanical safety lock and the pusher's special parking position

6 | Cutting unit

SINGLE-SHAFT CUTTING SYSTEM WITH FOUR-FOLD USEABLE POINTED KNIVES

  • PARTS STORAGE MADE EASY thanks to identical knives for the rotor, counter knives and scraper
  • MAXIMUM UPTIMES ensured by four-fold usable, quick-change knives
  • LOW WEAR PART COSTS thanks to four-fold usable square knives 
  • EASILY ADJUSTABLE CUTTING GAP – even during operation – for consistently, high-quality output

Fire prevention

THAT’S HOW TO PLAY IT SAFE

Lindner’s modern out-of-the-box FPS solution automatically detects and cools over heated particles in the material stream directly on the discharge conveyor, effectively preventing possible sources of fire. The system adapts the cooling process to the hazardous situation to ensure the facility operates optimally at all times.

  • Precise detection of overheated materials
  • Comprehensive monitoring of the entire cooling section
  • Cooling process adapted to the hazardous situation
  • Independent cleaning of the infrared sensors
  • Temperature resistant and robust thanks to a special insulation system
  • Highly flexible modular design
