Shredding Items

Types of media and materials that the shredder can utilize. Note that, by definition, all such devices are capable of working with paper documents, so paper is not mentioned in this paragraph (some models are generally only compatible with paper and do not allow using other materials). However, shredders with the ability to utilize various additional items are more common — mainly staplers, paper clips, credit cards and/or CDs/DVDs. Here are the features of each of these options:

— Staples. An auxiliary function designed to ensure that stapled materials do not have to be separated before being loaded into the shredder. Allows you to significantly save time when utilizing of such materials, especially in large volumes; also provides a correct operation guarantee in case of accidental contact with the staples.

— Paper clips. Paper clips are removed much easier than staplers and there is no problem with them even with a large amount of documents. Therefore, this function is rather an insurance against getting such a clip into the device along with the document.

— Credit cards. The ability to recycle various plastic cards with magnetic media — credit cards, passes, etc. This feature at least prevents the illegal use of such cards, and with a high security level it allows you to...keep the fact of the existence of a card in secret. Actually, the security level for such utilization is indicated in the generally accepted standard DIN 66399, as like as for paper, and there are seven of them:
  • 1 — the card remains intact, its surface is mechanically damaged;
  • 2 — the card is cut into pieces with an area of less than 2000 mm²;
  • 3 — size of pieces less than 320 mm²;
  • 4 — less than 160 mm²;
  • 5 — less than 30 mm²;
  • 6 — less than 10 mm²;
  • 7 — less than 2.5 mm².
— CDs/DVDs. Ability to utilize optical discs, which can also store confidential information. For such media, DIN 66399 also provides 7 security levels:
  • 1 — the disk is cut into pieces with an area of less than 2000 mm²;
  • 2 — less than 800 mm²;
  • 3 — less than 160 mm²
  • 4 — less than 30 mm²;
  • 5 — less than 10 mm²;
  • 6 — less than 5 mm²;
  • 7 — less than 0.2 mm².

Fragment sizes

The largest possible size of the fragments that come out from the shredder after being processed. However, it's told about fragments only in the case of using cross-cutting; for stripe cut models (see “Cut Style”), this item indicates the largest width of the stripes. The size of the fragments is directly related to the security level provided by the shredder; see the relevant paragraph above for details.

Shredding speed

The speed that processed unit moves through the shredding mechanism during utilization. Accordingly, the higher this indicator, the higher the productivity of the shredder and the more units it is able to shred in a certain time. Knowing the volume of the documents to be shredded, you can easily determine the time required for batch utilization: for example, with a speed of 45 mm/s, one load of standard A4 sheets (length 297 mm) will require 297/45=6.6 s.

However, it should be taken into account that this parameter is usually indicated for paper of a certain density — 80 g/m² (standard office paper) or even 70 g/m², depending on the manufacturer. When working with thicker paper, as well as other materials (see "Shredding Items"), the shredding rate may be significantly lower than stated.

Sheets per load

The number of sheets that the shredder is capable of processing at one time — in other words, the largest size of a stack of sheets that can be loaded into the device. Most modern shredders can handle multiple sheets; up to 5 pcs at a time is considered a very limited indicator, up to 10 pcs — a small one, 11 – 15 pcs can be called an average value, 16 – 20 pcs — quite good, and in the most powerful models this figure exceeds 20 pcs.

Note that this parameter is given for paper of a certain grammage (and, accordingly, thickness). At the same time, the East European standard for office paper is a grammage of 80 g/m², and in many European countries thinner paper is used with a grammage of 70 g/m², and it is for it that the capacity of many shredders is indicated. Therefore, if this moment is not specified in the specs, it is best to load the shredder not up to limit values, making a margin of 1 sheet per 8 sheets of capacity — 1 sheet with a stack thickness of up to 8 sheets, 2 sheets with a stack thickness of 8 to 16 sheets, etc. However, other conditions for density may be specified in the user manual.

Also note that the number of sheets per load is determined by manufacturers based on the results of tests under perfect conditions — in the absence of staples on paper, with low humidity,...optimal voltage in the mains, perfect sharpening of knives, etc. In fact, any deviation from these indicators affect some decrease in efficiency.

Duty cycle

The duty cycle of the shredder is the maximum time that it can work without interruption.

Limit of operating time is due to the fact that the destruction of documents and other media is associated with quite significant loads on the electric motor and gear. This leads to strong heating, while the breaks allow the hardware of the shredder to cool down. Actually, there are models with the possibility of continuous operation, but they are expensive and not always really necessary; see "Features" for details.

In small shredders for domestic use, the work cycle is often only a few minutes, and among powerful professional devices there are values of half an hour or more. Also note that in some models, shutdown after a full cycle is provided automatically due to overheating protection (see "Features"), however, the presence of such a system does not mean the presence of an automatic shutdown on time — it can only work with a critical increase of temperature.

Break time

The minimum break time required by the shredder after a full cycle of work (see above).

A break is required so that the motor and mechanisms of the device can cool down after the intense loads that they are subjected to during operation. Moreover, if the operating time was less than a full cycle, then the break can also be made shorter; however, if the device has worked for more than half of the cycle, for a full assurance it is still worth to take a break for all the time intended for it. Some models may provide other recommendations in this regard — they should be specified in user's manual.

Motor power

The power of the motor that drives the exterminator knives.

Engine specs are selected by manufacturers in such a way that the unit is guaranteed to be able to complete the tasks it's intended to. Therefore, while choosing the shredder this parameter has minor importance, the main attention should be paid to more lifelike specs — the sheets-per-load capacity, the speed of destruction, etc. However, devices of a similar degree of secrecy and price category may differ in power. In such cases, the difference is that a more powerful motor is capable of providing a thicker load stack, a faster shred rate, and/or a longer duty cycle (see above). The cons of these benefits are an increase in cost rate and energy consumption.

Regarding energy consumption, it is also worth noting that the motor power usually more or less corresponds to the total power consumption of the shredder. This data can be useful for some specific calculations — for example, calculating the total power of the load connected to an uninterruptible power supply.

Features

Auto start/stop. The system of automatic switching on and off of the shredder facilitates its use. To control the process in such models, you do not need to press buttons or perform any other additional actions: just place the processed material into the working gap and the shredder will start the utilizing process itself, and turn off automatically upon completion.

Reverse. Possibility of rotation of knives of the shredder in reverse direction. This feature has several uses. One of the most obvious is to correct the situation when the knives are jammed (for example, if a stack of paper is too thick) or the mechanisms are clogged: by turning on the reverse, you can easily remove jammed materials from the working mechanism. Also, the reverse can be useful in cases where it was necessary to clarify something from an incompletely cut document. In addition, the disposal of plastic cards and optical discs (see “Destroys”) in most cases (although not necessarily) is carried out precisely in the reverse mode.

— Continuous work. This feature means that the shredder does not require interruptions in work and can utilize of a large amount of documents without any pauses (at least regarding daily duty cycle — see above). Such units are extremely convenient for large volumes of work, when the volume of a single portion of recyclable materials can be measured in thousands of sheets. On the othe...r hand, continuous operation requires very high reliability of the motor and gear, which significantly increases the cost. So it makes sense to specifically look for a model with the possibility of continuous operation only in cases where this function is fundamentally important.

Overheat protection. A security system that automatically turns off the shredder's motor when its temperature increase to critical level (usually this happens during long work at high loads). This allows you to avoid unpleasant consequences — from the breakdown of the device to the open fire. Note that in some models, overheat protection plays the role of a circuit breaker that trips at the end of the work cycle (see above); in others, this function only works in abnormal situations, with a significant increase in temperature due to a serious malfunction.

Bin full autostop. A sensor that monitors the fullness state of the basket and automatically turns off the device when it is full. Such a function not only eliminates the need to constantly monitor the fullness of the basket, but also prevents overloading due to the inability to push the next pack of materials into an overflowing waste bin.

Noise level

The maximum noise level produced by the shredder during operation. The lower this indicator, the quieter the device works and the more comfortable it is to use, the better it is suitable for conditions that require silence (for example, libraries or archives).

When assessing the noise level, it should be taken into account that the decibel is a non-linear measure unit, and noises with a difference of several decibels differ in volume by several times. For comparison, we can proceed from the following data: office shredders, positioned by the manufacturer as "quiet", have a noise level of about 55 – 60 dB, which corresponds to the volume of ordinary human speech. 65 dB can be compared with a loud conversation, 70 – with a noisy street, 75 – with a scream, and there is practically no higher volume among office models.
