Internal Pusher

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.

Consistent dosing

due to self-regulating hydraulics.




Easy feeding

with a completely internal construction.

Delightfully maintenance-free

thanks to the absence of guide elements.



No jamming

 as a result of additional comb and sealing bars.

Robust shear cutting system


The shear cutting system specially developed for untreated municipal, commercial and industrial waste can handle even the most difficult materials. The secret to its productivity are the extremely hard steel alloys and the robust cutters and cutter holders designed to withstand even the hardest foreign objects.

High output

guaranteed with signature knife geometry.




Parts storage made easy

with identical knives, counter knives and scrapers.

Resistant to foreign objects

owing to sturdy knives in welded knife holders.



Long service life

as a result of multiple- use, quick-change knives.

Plug & GO Siebeinheit

Countershaft Drive

More efficiency with our smart technology: our countershaft drive stores and releases rotational energy depending on the load, meaning more power yet less energy consumption.

Load-dependent energy release

 thanks to countershaft drive.




Readily Available

Our easily replaceable standard components are readily available worldwide.

More power for tough materials

ensured with additional flywheel mass.




Readily available worldwide

due to easily exchangeable standard parts.



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 extremely precise sensors.

Fully adjustable

 to various materials.

Zweistufiger Riemenantrieb

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 quick-change screen units in various hole sizes.


Easy screen change

 due to our swivelmounted, hydraulically operated screen unit with individual screen modules.

Extremely safe operation

 thanks to the electromagnetically locked screen access point, preventing access to the cutting system while the machine is in operation.


Hydraulische Wartungsklappe

Hydraulic 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 foreign matter
quickly and cleanly

with the maintenance door at position 2.




Enjoy convenient maintenance access to the knives and counter knives

 with the maintenance door at position 3.

100% safe operation

thanks to the mechanical safety lock and the pusher's special parking position.

ATEX - Explosionsschutz


Legal directives in Europe, North America and Asia regulate the intended use of equipment in environments with explosive atmospheres, with zone classifications determining the minimum requirements for machines, components and inert materials. In accordance with the EU ATEX (Atmosphères Explosibles) directive for shredders, Lindner offers you products for use in zones 21 (shredders – indoors) and 22 (shredders – outdoors).


Water sprinkling system

Our optional water sprinkling system to reduce air-borne dust at the filling area offers a central water pipe with four nozzles in the enclosed hopper with suction point which can be easily activated via the control panel or the remote control. The system is designed for year-round use (down to -25°C).



The fire extinguishing system detects sparks and overheated objects, protecting the system when easily flammable materials are being processed. The sensors monitor not only the shredder but also the discharge conveyor and where necessary trigger the extinguishing process. Thanks to the central water supply, the pressure tank is subsequently filled automatically and once again ready for use.

Feeding Unit for Bulky Goods and Bales

The pusher with extended path provides more space between the cutting system and the pusher, allowing for carefree feeding of larger-volume materials and optimising the processing of bulky goods or bales.


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 Linder Polaris shreds twice as much material as comparable machines in the same period of time.*

Enerco – Energy Recovery Ltd - Polaris 2800

Enerco – Energy Recovery Ltd, associated company of Vassiliko Cement Works, commissioned a Lindner shredder from the Polaris series to shred high-calorific refuse derived fuels (RDF). The treatment of local waste streams more than doubled.

Patented SF Cutting System

November 2020. Precision with maximum efficiency: How Lindner's patented twin-shaft cutting system ensures high throughputs and a homogeneous final fraction for example in waste wood shredding. 

Fire Prevention System (FPS)

One of the most pressing recent issues in the mechanical processing and conversion of waste into solid recovered fuels is the high fire risk caused by damaged batteries. This risk can be minimised with Lindner's FPS.

Polaris 1800

SRF shredding in one go – with only one machine: the market launch of the Polaris at IFAT 2016 triggered a boom in demand for Lindner's innovative, highly specialized shredder. The new Polaris 1800 model has been introduced recently.

Waste Wood System Solution

Whether furniture, bulky goods or other waste wood, Lindner is a reliable partner when it comes to waste wood processing. At IFAT 2018 the Austrian company with 70 years of engineering experience presented its new mobile system solution.

Economical production of alternative fuels for calciner firing

If you want efficient plants for turning municipal, commercial and industrial waste into fuel, you first have to define the end product.

Preview: Lindner at RecyclingAKTIV 2019

July 2019. A multitude of different configuration options make Lindner’s mobile shredders and system solutions the perfect choice for universal waste processing.
