4-SHAFT INDUSTRIAL SHREDDERS - "TRITOTUTTO" series - As per E.C. rules
Traditional "Tritotutto" 4-shafts industrial shredders represent the vintage shredding line on the market for over 10 years.
Industrial shredders are machines able to shred all types of waste, whether urban or industrial such as plastic materials, paper, cardboard, wood, packaging, shells, fruit stones, leather and hide waste, bark, cans, tyres, copper items.
- They are ideal for small-medium sized companies.
- They are versatile, and adapt to different kind of waste.
- Shredders have low energy consumption.
- Shredding plants have low noise.
These industrial shredders can be customized to meet customer requirements thanks to a wide range of accessories: K2D cutters, supplementary screen, Automated loading hopper, Automated loading box and trolley cum hopper, conveyor belts, big-bag packaging system.
"TRITOTUTTO" is a rotating blade grinder that has been designed for use in small to medium sized firms to reduce the volume of scrap in order to store its in silos or to facilitate their disposal.
They are machines that have a low electrical input, run silently and are very reliable. Reliability is a consequence of the instalation of a torque limiting device which can be adjusted according to the product to be ground.
It can be used to reduce the volume of scrap from: plastic materials, cardboard, packing materials, wood, hide, leather, nut shells and fruit stones, wood bark, loppings of trees.
It can be connected to an aspirator using a tube placed under the screen.
The machine is driven by an epicyclical reduction gear whereas the linkage between the cutter holders and conveyors is by oil bath lubricated gears.
Each machine is equipped with a set of spanners to carry out disassembly of the cutters should they need sharpening. A clear technical manual illustrates the methods of carrying out this operation.
All the models are equipped with screens varying from 14 to 38 mm. depending on the size of the shredded material required. The smaller the size required the less the machine will produce.
The other features of these machines are:
- operating noise less than 80 dB: silent shredders
- shredder and conveyor disks easy to access to facilitate maintenance
- interchangeability of disks carried out directly by users
- low energy consumption
- possibility to shred any nonferrous material, even in the presence of nails, metal wire or stones and rocks
- EC certification.

OPERATION AND MAIN CHARACTERISTICS
The main characteristics of a grinder must be robustness and reliability; this is true of each of the parts of the machine, from the loading hopper and shredder unit to unloading.
From the technical point of view the shredder is made up of a loading unit, which very often has the characteristics of a simple hopper.
The function of this part should not be overlooked in that, in order to avoid problems in shredding it must be able to transport the material in the best way possible to the shedder unit.
The cutting action of the grinder is carried out thanks to a series of cutting elements which by intersecting shred the material.
The main parts of the system are made up of sharp edged disks, equipped with hooks. Each hook has the job of "hooking" the product and to transport it towards the cutters assembled on two or more counter rotating driving shafts which slice the material.
The grinding group is usually driven by an asynchronous ac electric motor which, linked to a gearmotor is able to produce the necessary forces needed in shredding.
When too much material transported or material which cannot be shredded builds up between the disks a thermoelectric couple temporarily inverts the rotation of the disks thus avoiding structural overloading or damage to the machine.
Experience acquired in the various sectors where employed enables the shredder group to be adjusted to the best of its possibilities without penalizing production capacity and regular operation.
The product is expelled after it has passed through a screen which selects the material that has reached the required size.
The larger items get hooked again by the hooks and are recycled for further shredding: it goes without saying that the smaller the diameter of the screen mesh the more recycling processes through the shredder the material will have to undergo.
From what has been said it is clear that the overall concept behind the shredder is quite simple but extremely efficient.
The biggest advantages gained in using it refer principally to the low rotation speed of the disks. On the contrary to what happens in traditional mills, the cutting torque available is inversely proportional to the slower rotation speed of the shafts.
This characteristic enables it to operate with a low absorption of electric energy and decrease in noise level (less than 60 decibel).

To make the shredding operation and managing of waste even more economically favorable our company has developed a complete line of accessories.
The objectives that were set were the following:
- "customerization" of the shredding characteristics on the basis of customer requirements
- use of labor during the loading and discharging operations of the grinder reduced to a minimum
- operating friendly recycling operations of waste materials.
K2D cutters for shredding particularly hard materials or if there are nails or small metal parts present. Particularly useful for very rough waste.
Conveyor disks for light materials subject to "rising" over the cutters.
Interchangeable supplementary screen with mesh diameters from 14-18-25-30-35 mm. which set the size of the shredded product.
Hopper for automated loading, suitable for difficult materials (paper, hides, rags) where gradual loading puts the grinding group in the best working conditions.
Automated loading box. Automatic loading system for very long material such as scaleboard or trimmings from various sources. It is extremely useful for loading and shredding bulky waste.
Trolley cum hopper with automatic tipping. Inexpensive loading system where the specific trolley waste bins are attached directly to the shredder. Each trolley with caster wheels can be stationed in various places in the plant thus facilitating collection and managing of waste materials.
Turning wheel trolley For the automatic collecting and loading of shredders.
Belt loading and transport systems. Conveyor belts of different types for loading and handling of waste before and after shredding.
Screw unloader. Different capacity screws for loading the boxes of shredded product.
Suction and automatic bag-filling. Trolley with suction and bag-filling equipment which can be connected to the shredder to facilitate managing of shredded product.
Briquetting press Compacting machine for paper, wood, rags, hides into small cylinders diam. from 50 to 80 mm. with output between 25 and 175 kg/h according to materials and models.
Refinement group which can operate together with the shredder. Should you require sizing of less than 12 mm., a refiner with an interchangeable grill, is available for the wood sector.
Circular vibrating screen for complete retrieval of packed granulated or powder products (coffee, cocoa, flour, fruit juices, etc). The shredder allows a fast opening of cartons, packets, etc favouring the discharge of the product that is sieved and recycled.
