Operation Attention

1, plastic crusher and power unit to install firmly. 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.

FAQ(Click and See More)

Is there such a thing as a quite shredder?

While most shredders generate some level of noise during operation, there are some models that are designed to operate more quietly than others. These shredders are often referred to as “quiet shredders” or “low noise shredders.”
Quiet shredders typically use advanced technology such as insulated motor housings, noise-reducing blades, and soundproofing materials to reduce noise levels during operation. They may also have a slower shredding speed, which can help to reduce noise.
The level of noise reduction offered by quiet shredders can vary depending on the model and the materials being shredded. However, in general, they can significantly reduce noise levels compared to standard shredders, making them a good choice for offices or other environments where noise levels need to be kept to a minimum.
When shopping for a quiet shredder, it is important to look for models that are specifically designed for low noise operation and have noise reduction features. It is also a good idea to read reviews and check the manufacturer’s specifications to get an idea of the noise level that the shredder produces.

How loud is a shredder?

The noise level of a shredder can vary depending on several factors, such as the type and size of the shredder, the materials being shredded, and the speed of the shredder. However, most shredders produce noise levels that range from around 60 decibels (dB) up to 100 dB or more.
To give you an idea of how loud this is, a normal conversation typically produces around 60-65 dB of noise, while a vacuum cleaner can produce around 70-80 dB. A shredder operating at its maximum capacity can produce noise levels of up to 100 dB, which is roughly equivalent to the noise level of a power saw or a motorcycle.
However, it is important to note that the actual noise level produced by a shredder can depend on various factors, such as the distance from the shredder, the materials being shredded, and the environment in which the shredder is being used. Additionally, some shredders are designed to operate more quietly than others and may produce noise levels closer to the lower end of the range.
If you are concerned about the noise level of a shredder, you may want to consider purchasing a model that is specifically designed for low noise operation or using the shredder in a separate room or area to reduce noise levels. It is also a good idea to wear ear protection if you are going to be using a shredder for an extended period of time.

Why is my shredder so loud?

There are several reasons why your shredder might be producing more noise than usual:
Dull or damaged blades: If the blades in your shredder are dull or damaged, they may not be cutting the material efficiently, which can cause the motor to work harder and produce more noise.
Overloading: If you are trying to shred too much material at once, this can put a strain on the motor and cause it to produce more noise.
Poor maintenance: If your shredder is not properly lubricated or maintained, this can cause the motor to work harder and produce more noise.
Age: As shredders get older, the motor and other components can wear down, which can cause the machine to produce more noise.
Design: Some shredders are simply louder than others due to their design and construction. Cheaper models may also use lower-quality components that can produce more noise.
To reduce the noise level of your shredder, you can try the following:
Sharpen or replace the blades: If the blades are dull or damaged, this can be causing the shredder to produce more noise.
Don’t overload the machine: Only shred the recommended amount of material at one time to prevent the motor from working too hard.
Perform regular maintenance: Keep your shredder properly lubricated and clean to help reduce noise levels.
Consider upgrading to a quieter model: If your current shredder is particularly noisy, you may want to consider investing in a quieter model that is designed for low noise operation.
Overall, if you are concerned about the noise level of your shredder, it is important to take steps to reduce the noise and prevent any potential damage to the machine.
