Industrial Shredder Machine

Industrial Shredder - Heavy-Duty Industrial Shredders

Optima offers single shaft and double shaft industrial shredders for reducing plastic scrap, wood, rubber, tires and selected metal waste. Choose the machine around the material you feed, the size of each item and the output required by your next recycling process.

Compare the two shredder types below, review the available machine dimensions and send your material details for a configuration recommendation.

What Materials Do You Need to Shred?

A solid plastic block, a roll of film and a hollow metal container place different demands on a shredder. Identify the actual item and its condition before selecting a model.

Your scrap material	Starting point for selection	What determines the configuration
Plastic lumps, purgings and molded scrap	Single shaft shredder for controlled discharge	Polymer type, block thickness and individual piece weight affect cutting load. A hydraulic pusher feeds the material toward the rotor.
Plastic pipes and pipe fittings	Single shaft or double shaft, depending on dimensions and output	Pipe outside diameter, wall thickness and length determine the feeding arrangement and whether pre-cutting is needed.
Plastic film and woven bags	Single shaft assessment for controlled output	Loose film, rolls and compressed bales feed differently. The pusher and cutter arrangement must suit the material’s flexibility and bulk density.
Wood pallets and solid wood scrap	Single shaft for controlled discharge; double shaft for coarse reduction	Pallet dimensions, timber section thickness and embedded fasteners influence feed preparation and cutter selection.
Waste tires and rubber products	Double shaft assessment for primary reduction	Tire diameter, width, reinforcement and required chip size determine the model and subsequent processing stages.
Aluminum profiles, metal containers and selected metal scrap	Double shaft assessment	Alloy, wall thickness, attachments and whether the item is hollow or solid matter more than the label “metal scrap.”

The material categories above cover different configurations across the range. They do not mean that every model accepts every listed item.

Choose a Single Shaft or Double Shaft Shredder

Single Shaft Shredder Models for Screen-Controlled Discharge

Choose a single shaft shredder when your process needs material to pass through a sizing screen before discharge. The rotor cuts against stationary knives, while a hydraulic pusher brings material into the cutting zone.

This configuration provides a useful starting point for plastic lumps, pipes, film and wood that require further granulation or a more controlled feed to the next process.

Double Shaft Shredder Models for Primary Size Reduction

Choose a double shaft shredder when the first task is to grip and reduce bulky material into a manageable pre-shred. Counter-rotating cutters shear and tear the feed.

This configuration is worth assessing for tires, hollow containers, selected metal scrap and bulky mixed materials where coarse output is acceptable. A further sizing stage may be needed before downstream processing.

Selection point	Single shaft	Double shaft
Main cutting arrangement	Rotor, stationary knives and sizing screen	Two counter-rotating cutter shafts
Feeding consideration	Pusher engagement with the material	Cutter grip and entry into the cutting zone
Discharge control	Screen opening influences discharge	Cutter configuration and material behavior influence fragment shape
Typical process objective	More controlled size reduction	Primary reduction and volume reduction
When another stage is needed	When finer material is required	When coarse pre-shred does not meet the final size requirement

These are starting points for selection. Rotor design, cutters, feeding equipment and the specific material still determine suitability.

What Size Material Can the Shredder Accept?

Specify the largest intact item you intend to feed, including its length, width, height and weight. For pipes and profiles, add the outside dimensions and wall thickness. For rolls or bales, add their dimensions and density if known.

Hopper dimensions describe the machine opening; they are not a guaranteed maximum workpiece size. A bulky hollow item and a solid block with similar external dimensions can require different cutting capacity and preparation.

Selected Single Shaft Shredder Specifications

Model	Main motor power	Hydraulic power	Listed hopper size	Listed screen opening range
OSX3880	45 kW	4 kW	700 × 850 mm	40–100 mm
OSX46120	55 kW	4 kW	800 × 1,200 mm	40–100 mm
OSX75150	2 × 75 kW	7.5 kW	1,100 × 1,500 mm	40–100 mm

Use the hopper dimensions to shortlist machines for a material assessment. Maximum intact feed dimensions, allowable thickness and feeding orientation must be established for the selected material.

Selected Double Shaft Shredder Specifications

Model	Listed motor power	Shaft speed	Rotor diameter	Blade thickness
OSL2360	18.5 kW	16–25 rpm	290 mm	25 mm
OSL26100	22 kW	16–25 rpm	320 mm	40 mm
OSL41160	2 × 45 kW	10–15 rpm	534 mm	50 mm

Rotor diameter and blade thickness describe the cutting assembly. They do not establish the maximum feed opening or guarantee a matching final particle size. Include the dimensions of your largest item when requesting the relevant chamber drawing and model recommendation.

Match Shred Size to Your Next Recycling Stage

For volume reduction, coarse fragments may meet the handling requirement. For washing, separation or further granulation, define the size and shape that the next machine can accept.

On a screen-equipped shredder, the screen influences when material leaves the cutting chamber. Flexible or elongated pieces may behave differently from rigid fragments, so specify any restrictions on long strips and oversize material.

If your process needs finer granules, evaluate the shredder together with a downstream granulator. Shredding reduces size; it does not by itself establish material purity or remove every contaminant.

For a complete installation, review the feed, discharge and separation requirements through our Solid Waste Shredding System.

Compare Throughput on the Same Material

Compare capacity using the same feedstock, preparation and target output. Loose film, dense plastic blocks and hollow containers cannot be assessed from motor power alone.

For a useful production comparison, record:

Material type, composition and contamination.
Typical and maximum feed dimensions.
Loose, baled, rolled or pre-cut condition.
Screen or cutter configuration.
Feed weight, elapsed processing time and interruptions.
Output size and the amount requiring further processing.

Include both your hourly target and working hours per shift. This helps distinguish the required processing rate from the total daily workload.

Blade Options and Replacement Parts

Optima lists integrated blades and replaceable hook configurations for its Double Shaft Shredder Blades. An integrated blade is replaced as a complete disc; a replaceable hook arrangement allows the cutting component to be serviced separately.

Available double shaft blade materials include H13, D2 and 42CrMo. Selection should account for the actual feed and cutter design rather than steel grade alone.

For replacement or customized blades, provide the machine model, existing blade dimensions and material being processed.
