How to choose the right shredder blade?

Because shredders' blades sometimes face large metal steel blocks or wood and stone blocks in industrial processing, this requires the shredder itself to have good performance. For shredders' blades, they should basically have impact resistance and their material should be high hardness and high wear resistance. When selecting shredders' blades.

 

How to choose the right shredder blade?

First understand the performance of the shredder

First of all, we should understand the performance of the shredder. The blade is the main component of the shredder, and the quality of the blade directly affects the production efficiency and production cost of the shredder. Therefore, when selecting the blade, we should consider the shaft, blade and blade together. Firstly, there are various materials for the shredder blade, including steel and alloy cast iron, which are used to enhance the rigidity and wear resistance of the shredder. Secondly, we should look at the material of the shredder shaft, which is mostly made of alloy steel to increase its wear resistance and service life. Thirdly, we should look at the blade of the shredder, which can be divided into single-piece and double-piece. The single-piece can be divided into two types: hard steel and alloy steel. Finally, we should look at whether the material of the shredder shaft is stainless steel, which has strong corrosion resistance and long service life.

Look at the material of the shredder blade

Shredding machine blades are usually made of wear-resistant alloy materials. This material has good toughness, impact resistance, wear resistance, and high hardness, resulting in long service life. Therefore, alloy blades are commonly used for shredding machines.

1. Material of shredder blade: Shredder blades are usually made of high carbon alloy steel, which is characterized by corrosion resistance and wear resistance.

Surface treatment of shredder blades: When the shredder blades undergo surface treatment, they are generally plated with nickel, chromium, copper, etc. For expensive shredder blades, if high quality is desired, electroplated materials are the best choice.

3. Weight of shredder knife body: Generally, the weight of shredder knife body is determined by the shredded material, and a heavier weight generally brings better user experience.

Look at the knife shaft

The quality of the shaft directly affects the life of the shredder, so when purchasing shredder blades, it is important to observe the quality of the shaft.

The hole on the knife shaft must be circular arc shaped, not straight-angled, so that the knife holder can maintain stability during high-speed motion during use, thereby extending the service life of the knife shaft and knife holder.

The bearing on the shaft must have sufficient hardness and wear resistance. Over time, the bearings will wear out, and insufficient lubrication of the bearings will lead to problems such as bearing heating, spindle loosening, and noise increase. Therefore, shredders require long service life.

3. The blade should be kept flat during processing, and the blade holder should be secured on the blade shaft during installation. After the blade holder is fixed, it is important to check whether the blade shaft is tilted, as this can affect the normal operation of the shredder.

The quality of the blade

The quality of the shredder blade must be ensured during the processing process, which is crucial to the quality of the shredder blade.

1. First check whether there are cracks on the cutting shaft, as cracks can affect the normal operation of the shaft and, in severe cases, can lead to shaft breakage;

Check whether the lower knife shaft is bent, as this will affect the normal use of the shredder blades;

After installing the blades on the shredder blade body, the blades must be ensured to be installed smoothly, which is crucial for the effectiveness of the shredder blade.

3. First check whether the knife body and shredder blade are firmly installed;

4. Then ensure that the knife shaft and the knife body are not loose.

The use of shredder blades is a manifestation of mechanized processing in production and life. It is an accessory of the shredder, and shredder blades play an important role in processing metals, waste materials, and crushing raw materials. So how to choose shredder blades in industrial production?

I. Purpose

In the shredder blade, it is divided into single-axis shredder blade and multi-axis shredder blade. From its classification, we can know that different blade axes have different shapes, appearances, even uses and performance. The multi-axis shredder blade also has four axes and six axes. Different production situations require different types of shredder blades. Even if a dual-axis type of shredder blade is selected, its size and material should also be considered. When purchasing shredder blades, depending on the production situation, choose a specific size. If it is a non-standard size, it can also be customized by the market to a certain specification. Generally speaking, shredder blades need to be customized or purchased in batches. The shredder achieves cutting and crushing materials by the operation of multiple blades, which fit together with each other.

II. Material

Because shredders' blades sometimes face large metal steel blocks or wood and stone blocks in industrial processing, this requires the shredder itself to have good performance. For shredders' blades, they should basically have impact resistance and their material should be high hardness and high wear resistance. When selecting shredders' blades, they should also be inspected to meet the most basic performance requirements of shredders' blades.

III. Sales Service

True gold is not afraid of fire, and good shredder blades should have corresponding after-sales services that can provide sales guidance for the use and unexpected situations of shredder blades.

What are the installation steps for shredder blades?

The installation steps of shredder blades are as follows:

First, turn off the power switch of the shredder and disconnect the power plug to ensure safety.

2. Open the top cover of the shredder, usually by pressing or rotating the top cover release button.

3. Observe the inside of the top cover and look for the screws or snaps that secure the blades. If there are screws, use a suitable screwdriver to loosen and remove them; if there are snaps, follow the instructions or use a push rod or other tool to release them.

4. Carefully remove the original blade from the top cover of the shredder to ensure that you do not get injured.

5. Install the new blade into the shredder top cover, ensuring that it is correctly aligned with the shredder's spindle and that the edge of the blade is aligned with the shredder's cutting partition.

6. Fix the blade with the spindle of the shredder. If using screws, tighten them; if using snaps, snap them again as instructed.

7. Close the top cover of the shredder to ensure that the blades are securely installed.

8. Switch on the power and turn on the power switch of the shredder for testing to ensure that the blades are installed correctly and can operate normally.

Please note that before installing the blade, ensure that the power supply is disconnected and follow the specific installation steps and usage guidelines provided by the manufacturer.
