MATERIALS OF INDUSTRIAL SHREDDER BLADES

The materials of shredder blades are usually: M6V, 55sicr, H13, 3cr13, SKD11, DILLIDUR 550, 4140HT, HARDOX550, etc.

These materials have excellent wear resistance, corrosion resistance and high hardness, which can maintain the sharpness and strength of the blades during long working hours.

DESIGN CONCEPT OF SHREDDER BLADE SHAPE

According to the different uses of the shredder and the material characteristics, a reasonable blade shape is designed. The design of the blade shape should take into account the combined effects of cutting, tearing and squeezing to improve shredding efficiency. At the same time, the blade shape must also take into account the strength and rigidity of the blade to avoid deformation or breakage during work.

WORKING PRINCIPLE

The double-shaft shredder consists of two counter-rotating cutter shafts, each of which has multiple blades arranged in a staggered manner. When the material enters the shredder, the two cutter shafts rotate in opposite directions, and a shearing action is quickly formed between the blades to cut the material into smaller pieces. In addition to shearing, the teeth on the blade also tear and squeeze the material. This effect can break the material into smaller particles, and can also effectively separate impurities and metals in the material.

SHREDDER MACHINE BLADES MANUFACTURING PROCESS

The manufacturing process of shredder knives and blades is very critical and is directly related to the quality and performance of the blades. Shengzhong’s dual-shaft shredder blades adopt advanced thermoforming, high-precision CNC machining and other technologies. Through thermoforming technology, the hardness and toughness of the blade can be adjusted to make it more wear-resistant and impact-resistant. High-precision CNC machining technology can ensure the shape and size accuracy of the blade and improve shredding efficiency.

After completing forging, heat treatment and surface treatment, the shredder knives and blades needs to be inspected, the quality inspection include the appearance inspection, dimensional measurement, hardness test, etc. Ensure that the quality of the industrial shredder blade meets the design requirements and can meet the usage requirements of the shredder.

Application

Double-shaft shredder blades and four shaft shredder blades are widely used in various occasions that require shredding processing, such as waste plastics, rubber, wood, paper, tires, electronic waste, etc. After these materials are shredded, they can be more conveniently processed for subsequent processing, such as recycling and reuse. At the same time, the dual-shaft shredder blade is also suitable for shredders of different sizes and outputs, and can play a good role from small laboratory equipment to large industrial production lines.

FAQ

For different requirements, we will choose more suitable steel: for example, when shredding food waste, we usually use 440C, 3Cr13 and other stainless steel materials, which have good corrosion resistance. When shredding scrap metal, we need to consider the sharpness of the blade. and toughness, usually we use H13, HARDOX550, DILLIDUR 500. Each steel has unique characteristics, and we should choose the most suitable steel.

We will consider many factors when choosing the blade size: the type and nature of the material, shredder model specifications, capacity and effect, budget and cost. Generally, the larger the material, we will use a larger blade. For example, for bulky waste, we will use the diameter. For blades above 500mm, used cars not only need a larger blade size, but also a larger blade thickness. We usually use 80mm thick blades.

1.Preparation stage

Let the shredder be turned off first and disconnect the power supply to ensure safe operation.

Prepare necessary tools and lifting equipment

Prepare a new blade and a quick, open space

2. Disassembly

Disassemble the shredder chamber and place it on the open ground

Remove all screws and lift the entire blade shaft out. And check whether the seals, bearings, etc. are aged and worn. If so, please replace them in time.

Remove the blade from the spindle

3. Replace with new knife and assemble

Replace the blade and assemble.

Note:

(1) It is best to do it on a flat ground during the assembly process.

(2) Do not miss any parts during the assembly process such as circlips and sealing rings.

4. Inspection and maintenance

Maintain the shredder: for example adding butter

Start the shredder and perform an idling test

Usually when the blade becomes dull or the shredding effect is not as good as before, we will grind the blade.

First, the blade teeth can be polished with a polishing machine. If the wear is serious, wire cutting can be used to cut the blade teeth.

Then, a grinder can be used to grind the flat surface of the shredder blade. It is worth noting that before grinding the shredder blade, The spacers must also be ground.

The second method is the repair welding process. For this method, you can contact us for consultation.
