2 shaft shredder with a special transmission

Leave a comment

SatrindTech presents the innovative industrial shredder drive system with automatic transmission and frequency inverter

This system combines the automatic adjustment capabilities of torque and the typical speed of a hydraulic drive, with the advantages of an electric drive. These are the main features:

Productivity – For the same amount of torque developed, the mechanical automatic transmission ensures a higher rotation speed, and thus an increase in productivity compared to a hydraulic system of the same power. The variable-frequency drive allows an additional increase in productivity when the process does not require the maximum drive torque.

Compactness – It is a plug-in system on the shredder, available also as a retrofit for existing shredders. No more hydraulic power-packs and oil piping lines.

Noise level – The level of noise emissions is that of an electric machine, significantly lower than the noise emitted by hydraulic drive systems.

Maintenance – Drastic reduction of routine maintenance costs (filters and oil in control unit) and significant reduction of extraordinary maintenance costs (hydraulic valves, pumps and motors).

Our Sales and Marketing Service is on hand to provide you with any technical information you may require and to put forward our solutions for shredding material.

2-Shaft shredder for secure document destruction

The secure destruction of the hard disk: from today, with SatrindTech it’s even easier

Every time that we install programs or apps for our smartphones, when we use internet services or we sign modules, we consent to the treatment of our personal data, which is generally digitized on electronic supports (generally hard disks).

Correct management of our privacy requires total protection of the data contained, even during the destruction phase, of these supports.

International laws relative to the secure destruction of documents are numerous, establishing different methods of destruction, and providing different levels of security in relation to the class of protection required. Among these laws are cited:

• UNI 15713:2009 Secure destruction of reserved documents
• DIN 66399-1 Office machines – Destruction of data carriers – Part 1: Principles and definitions
• DIN 66399-1 Office machines – Destruction of data carriers – Part 2: requirements for equipment for destruction of data carriers
• BS 8470:2006 Secure destruction of confidential material. Code of practice
• Other specification from NSA (National Security Agency) and ASIO (Australian Security Intelligence Organization)

SatrindTech has created two industrial shredders models that are able to satisfy the security requirements defined by DIN 66399-1: S3/3RI (da 4hp) and F410/360RI (da 10hp).

With these shredders it is possible to destroy up to 25 and 100 hard disks per hour respectively, obtaining a final material piece size of less than 80 mm2 (with a 12 mm grill) and less than 35mm2 (with 8mm grill), allowing, in this way, to work at an H5 level of security (where the maximum dimensions of this level are from 10 mm2 to 320 mm2).

The shredding of the material is carried out in two phases within the body of the same machine: the first phase allows the reduction of the volume of the material inserted into the feeder, while the second phase is the effective granulation of the hard disk to the required dimension. The continuous recirculation of the material present in the shredding chamber allows for its exit only when it has reached a dimension inferior to that of the rotating grill selected.

For the technical characteristics of the proposed models, it is possible to download the technical specifications of the relative products, as well as watch a video about them:

Satrindtech new range of single shaft shredders

SatrindTech increases its product range with the new single shaft shredders: capacities from 11 to 250 kW, electric motors, hydraulic ram allowing the approach of the material to the rotor and interchangeable screens, those among the main characteristics.

Moreover, all the rotors are provided with plates of special steel, with different sizes to be defined according to the type of work, and singularly removable without disassembling the rotor for an easier maintenance. A PLC installed into the electric switchboard, with the purpose to better control the shredding cycle, completes the equipment.

These shredders are suitable for the treatment of several materials and waste such as RDF, MSW, plastic, wood, rubber, drums, IBCS, paper and pallets (see the video of some shredding trials)

The main models  are:

1K28: compact dimension;  electric motor from 11 to 37 kW ; shredding chambers from 550×600 up to 1300 mm

1K46: proper to handle high volume of material; electric motors from 75 to 110 kW of power ; shredding  chambers from 1200×1630 up to 2170 mm.

1K65: suitable for high throughput thanks to its large dimension; shredding  chambers from 1400×2000 up to 3000 mm; electric motors from 132 to 250 kW.

The single shaft shredders, unlike the two-shaft model , lend themselves to obtain, for the same volumes of treated material, a smaller and granulated size, difficult to be obtained with a two-shaft shredder unless with a second step of shredding . This thanks to the screens that selects the final size of the materials. Furthermore, the high speed of the rotor allows to achieve high throughputs.

With this range of single shaft shredders, and with its consolidated models with two, three and four-shaft, SatrindTech answers to all shredding problems of its customers in the treatment and recycling of waste, ensuring the products quality thanks to its know-how and experience.


Why buy a 2 shaft shredder with CL system ?

To obtain a controlled and reduced size in the shredding process can be used two ways:

  • a primary 2 shaft shredder coupled with a secondary shredder
  • a 3 or 4 shaft shredder with selection grid

In the first case, you may have a high capacity and a very controlled size, but is necessary to consider the price of two shredders. In the second case the flow is reduced to the advantage of size and in any case it is necessary to evaluate the cost of a 3 shaft shredder.

SatrindTech provides a solution that allows to combine the controlled size content with the lower cost of a 2 shaft shredder, without the need for a secondary passage: the patented CL System (system to counter-blades).

The principle of operation is based on a special cleaning sector front blade that accompanies and forces the material towards the grid below the blade. The material will be ejected from the shredding chamber with a width defined by the thickness of the blade and the width of the hole grid. Are possible combinations of the thickness of the blade and the shape of the hole grid, which affect flow rate and size in a different way.

The CL System is suitable particularly on materials such as plastic, including automotive components, metal containers and chip-ferrous metals, pharmaceutical and hospital waste, textile waste. Watch the video !

The CL System is applicable to our shredders with increasing powers from 10 to 300 HP.

Shredder on-board

The Directive MARPOL is the International Convention for the Prevention of Pollution of the seas. The annex V contains the rules for the prevention of pollution from solid waste discharged from ships. SatrindTech offers its own contribution to the reduction of this type of pollution by offering a range of shredders on-board for shipboard food waste.These shredders are designed to process small or high quantities of shipboard food waste. Output size waste less than 25 mm. These shredder are complaining with  MARPOL 73/78 – Annex V requirements. See our online stand on Nautic Expo the Online Boating and Maritime Exhibition.

2 shaft shredders CL system

Is on line our Google Adwords campaign about 2 shaft shredders redirected to a new landing page. CL System (Counter blades size selection system), is a unique technology within the shredder market that guarantees a small and uniform shred size from a 2 shaft shredder.
The CL System, which can be retro-fitted to all existing SatrindTech 2 shaft shredder models, is able to guarantee the output material size in the same way as 3 or 4 shaft solutions fitted with selection screens.
The uniformly sized material is suitable for incinerators, washing systems and separation systems.
