SatrindTech Industrial Shredders

SatrindTech industrial shredders are designed to reduce volume and prepare waste before sorting, separation, recycling, or recovery processes. Their range includes 2, 3, and 4-shaft shredders, with configurations for plastics, WEEE (Waste Electrical and Electronic Equipment), tires, pallets, drums, industrial waste and sanitary waste. At Reverter Industries, we analyze each application to select the most suitable model, shredding chamber, and configuration.

The choice of shredder depends on the type of waste, the input size, the processing flow rate, and the required final particle size. If you need to compare SatrindTech with other shredding technologies or learn about solutions for other materials and applications, please consult our range of industrial shredders for recycling.

Which SatrindTech shredder should you choose: 2, 3 or 4 shafts?

SatrindTech shredders offer different configurations depending on the type of waste, required processing capacity and desired output size. The choice between two-, three- and four-shaft machines depends on the material characteristics and the specific requirements of the process.

Configuration	Features	Typical applications
2 shafts	Volume reduction using two counter-rotating shafts. Suitable for bulky and heterogeneous materials.	Industrial waste, plastics, pallets, drums and tyres.
3 shafts	Combine size reduction with greater control over the processed material, depending on the configuration.	Plastics, paper, healthcare waste and electronic components.
4 shafts	Feature two pairs of shafts for more controlled shredding and a more uniform output material.	WEEE, plastics, industrial waste, wood and paper.

Choosing the right configuration depends on more than just the number of shafts. Other factors to consider include power, shredding chamber dimensions, blade thickness and required processing capacity.

At Reverter Industries, we analyse these parameters to select the most suitable SatrindTech model and assess its integration into the facility.

How to choose a SatrindTech shredder

Choosing a shredder shouldn’t be based solely on its power. To determine the right equipment, it’s necessary to analyze:

Type and composition of the material.
Maximum feed size.
Bulk density.
Moisture content and presence of impurities.
Required production rate.
Desired final size.
Feeding system.
Operating hours.
Equipment located upstream and downstream of the shredder.

At Reverter Industries, we analyze each application to determine the most suitable technology, shredding chamber, blade thickness, and auxiliary equipment.

Frequently asked questions about SatrindTech shredders

What is the difference between SatrindTech 2-, 3- and 4-shaft shredders?

2-shaft shredders are primarily designed to reduce the volume of bulky and heterogeneous materials. 3- and 4-shaft shredders allow for more controlled shredding, depending on the model and configuration, when the process requires specific characteristics of the output material.

Which SatrindTech model is suitable for shredding tyres?

Within the SatrindTech range, the K30 and K50 models are suitable for tyre shredding applications. The choice depends on tyre dimensions, required processing capacity and the operating conditions of the facility.

What is the difference between an electric and a hydraulic shredder?

Electric shredders use electric motors to drive the shredding shafts, while hydraulic shredders transmit motion through a hydraulic system. The choice depends on the material, required cutting force, operating conditions, and maintenance and operational requirements.

What processing capacity do SatrindTech shredders offer?

Processing capacity depends on the model, material and equipment configuration. The range includes compact shredders for moderate throughput as well as higher-capacity industrial machines. The values provided in the technical specifications are indicative and should be assessed according to actual operating conditions.

Can a SatrindTech shredder be integrated into an existing recycling plant?

Yes. Reverter Industries can assess the integration of a SatrindTech shredder into an existing facility, considering the feeding, conveying, sorting and separation systems, as well as the available space and required processing capacity.
