What is the particle size of Dual Shaft Shredder?

The discharge particle size of the Dual Shaft Shredder has a great relationship with the materials that need to be processed. For example, the discharge size of the Dual Shaft Shredder when crushing sofa, mattress and other large garbage is mostly between 100-300mm, and the discharge particle size when crushing kitchen waste is mostly in 20-200mm. Therefore, the discharge particle size of the biaxial shredding machine is generally between 20-300mm, which can be adjusted according to the specific needs. If you want a finer discharge size biaxial shredding machine is not very suitable (reasons will be mentioned below), then you can consider configuring a fine shredding machine.

Dual Shaft shredding machine discharge particle size is mainly determined by what?

After the Dual Shaft shredder crushing material to determine, the discharge particle size depends largely on the choice of blade, suitable blade can not only tear the required materials well, but also effectively improve the output, and inappropriate blade in the process of use often appear the discharge particle size is too large, shredding uneven, shredding incomplete, and even the phenomenon of breaking the knife. So how to choose the right blade, is very important.

Blade is divided into moving knife, fixed knife, we generally say blade refers to moving knife. Because the choice of knife, knife sleeve (sleeve) has been able to determine, the relative fixed knife is set down. The number of knife teeth (claw) determines the length of the discharge, the thickness of the knife determines the width of the discharge.

The discharge particle size of the commonly used biaxial shredding machine is more than 2cm. Why can’t the discharge particle size be realized again? Because again small, the thickness of the blade is less than 2cm, such a blade is too thin, short service life, easy to break the knife, especially for the hardness of slightly higher materials or long-term operation of materials is even more so.

What material is Dual Shaft shredder suitable for processing?

Biaxial shredding machine is widely used, because of its large output, high torque, wide applicability of materials and other advantages, it is often chosen by customers. Although, the biaxial shredding machine can almost break all the common solid waste in life, but it is still good at some areas and some areas not suitable for use, let’s understand some of it!

If need long-term fixed operation, plastic crusher should be fixed on the cement base; If the plastic crusher is needed for mobile operation, the unit should be installed on a base made of Angle iron, and ensure that the power machine (diesel engine or motor) and the belt pulley groove of the plastic crusher are in the same rotary plane. 2. After the installation of the plastic crusher, the fasteners of all parts should be checked and tightened if they are loose. At the same time to check the belt tightness is appropriate.

3. Before starting the plastic crusher, first rotate the rotor by hand to check whether the jaw, hammer and rotor are flexible and reliable, whether there is collision in the crushing room, whether the rotating direction of the rotor is consistent with the direction indicated by the arrow of the machine, and whether the lubrication of the power machine and plastic crusher is good.

4, do not casually replace the belt pulley, in case the speed is too high resulting in the explosion of the crushing chamber, or the speed is too low affecting the working efficiency of the crusher.

5. After starting the plastic crusher, it should be kept idling for 2~3min, and then feeding after there is no abnormal phenomenon.

6, the work should always pay attention to the operation of the plastic crusher, first of all, the feeding should be uniform, to prevent blocking the crushing chamber; Second, don’t overwork for a long time. If there is vibration, noise, bearing and body temperature is too high, spraying material and other phenomena, should immediately stop the machine for inspection, troubleshooting before continuing to work.

What is a two shaft shredder?

A two shaft shredder is a type of industrial shredder that has two parallel, counter-rotating shafts with interlocking blades or cutters attached to them. The two shafts rotate at low speed, typically between 10 and 50 revolutions per minute (RPM), and work in tandem to shred and reduce the size of various materials.
The interlocking blades on the two shafts work together to break down the materials into smaller pieces or particles. The two shaft design allows for a more efficient shredding process and can handle a wider range of materials compared to single shaft shredders.
Two shaft shredders are commonly used in the recycling and waste management industries to shred materials such as plastics, rubber, wood, paper, and metal. They are also used for the destruction of confidential documents and the processing of various products such as medical waste and electronic scrap.
The two shaft shredder design is more complex than that of a single shaft shredder, and they are typically more expensive to purchase and maintain. However, they are also more efficient and can handle larger volumes of materials, making them a good choice for industrial applications with high shredding requirements.
Two shaft shredders are available in various sizes and configurations to accommodate different materials and production requirements. They can also be customized with different blade configurations and screen sizes to control the size and quality of the shredded output.

What is the difference between single shaft and double shaft shredder?

The main differences between single shaft and double shaft shredders are:
Number of shafts: As the name suggests, a single shaft shredder has one rotating shaft with blades or cutters attached, while a double shaft shredder has two parallel, counter-rotating shafts with interlocking blades or cutters attached.
Shredding efficiency: Double shaft shredders are generally more efficient at shredding than single shaft shredders, as they have two shafts that work together to break down the material more effectively. This can result in a finer, more uniform shredding output.
Capacity: Double shaft shredders can typically handle larger volumes of material than single shaft shredders, making them a better choice for high-capacity shredding applications.
Types of materials: While both single and double shaft shredders can shred a wide variety of materials, double shaft shredders are generally better suited for tougher, more difficult-to-shred materials, such as metal, tires, and thick plastic.
Cost: Double shaft shredders are typically more expensive than single shaft shredders due to their more complex design and higher efficiency.
Ultimately, the choice between a single shaft and double shaft shredder depends on the specific shredding requirements and the types of materials being shredded. Single shaft shredders are often a good choice for general-purpose shredding applications, while double shaft shredders are more suited for industrial applications with high shredding requirements and tougher materials.

What type of shredder is most secure?

Cross-cut shredders are generally considered the most secure type of shredder, as they produce smaller particle sizes compared to strip-cut shredders. Cross-cut shredders use two sets of blades that cut the paper both vertically and horizontally, creating small, square-shaped pieces that are difficult to reassemble.
The size of the particle produced by the shredder is measured in DIN (Deutsches Institut für Normung) levels, with higher DIN levels indicating a smaller particle size and therefore greater security. Cross-cut shredders typically produce particles with DIN levels of P-4 or higher, which are recommended for shredding confidential or sensitive documents.
Micro-cut shredders are another option for those requiring maximum security, as they produce even smaller particle sizes than cross-cut shredders. Micro-cut shredders use multiple sets of blades to create tiny, confetti-like particles that are virtually impossible to reassemble. These shredders typically have higher DIN levels of P-5 or higher and are often used for shredding highly sensitive or confidential documents.
Overall, the level of security needed will depend on the sensitivity of the information being shredded and the level of risk involved. For most personal or business use, a cross-cut shredder with a high DIN level is sufficient. However, for extremely sensitive documents or government use, a micro-cut shredder may be necessary to ensure maximum security.
