4. Shredder performance determines price

The performance of the shredder is mainly manifested in stability, shredding efficiency, service life, and other factors, such as energy consumption, automatic intelligence and so on. The shredder with good performance has good output effect, high efficiency, and greatly saves costs. Relatively speaking, the equipment price is also high.

shaft:
The overall forging of the main shaft will not be deformed during long-term work when the equipment shreds high-strength materials. After vehicle processing, the CNC machining equipment stably ensures that the machining accuracy and the center accuracy of the machine tool will not exceed 5 wires. The professional processing equipment can ensure that the long-term operation and the accuracy of the machine tool exceed 5 wires. The distance between the fixed knife and the movable knife can be adjusted at least 0.5mm.

moving knife:
The special four-corner design of the shredding motor knife can be used repeatedly to save user costs. The imported knives ensure that the material SKD11 is pure and reliable. After many heat treatments and vacuum cryogenic treatments, the service life of the knives is guaranteed. Taking PE pipe head material as an example, it can crush more than 1000-1500 tons.

fixed knives:
The fixed knife line cutting of the shredder ensures that the error will not exceed 5 wires, so that the movable knife and the fixed knife on the main shaft of the equipment can be adjusted by a minimum of 0.5mm, and the imported materials ensure that the materials are pure and reliable

Shredder coupling function:
Connecting the Spindle and Gearbox
Features:
1. The power output of the shredder is guaranteed to be stable without damage.
2. Better protection of the shredding spindle and gearbox from damage. 3. Special customization is convenient for maintenance and inspection.

5. Brand influence

The brand factor also accounts for a large proportion. The shredders of big brands are more particular about the production process level, accessories and materials, especially the knives, whose service life and stability are incomparable to ordinary small factories. Therefore, it is recommended to Choose a well-known brand, and a well-known shredder manufacturer will naturally have a relatively high price.

6. The impact of shredder accessories on price and performance:

a. Steel: The material and thickness of steel plates used by different manufacturers to manufacture shredders vary widely. For professional shredding equipment manufacturers, the thickness of the plates needs to be recalculated according to the different shredding materials, which determines the cost. , which affects the final price;

b. Motor: The motor must use qualified products produced by the original factory, and must not use refurbished motors or defective motors to charge, because if the copper wires of these motors do not meet the requirements of the rated current, the motor is easy to burn out or the driving force is insufficient. , which affects the rotation speed of the shredder equipment and the overall shredding effect;

c. Bearing: The quality of the bearing directly affects the production and shredding effect of the shredder equipment. The bearing must be produced by a large manufacturer, and the bearing produced by a small factory should not be used, but at the same time, pay attention to counterfeit products;

Q HOW TO CHOOSE A SHREDDER? CLASSIFICATION OF SHREDDERS

A
How to choose a suitable shredder is a major problem that has plagued the recycling customer group for a long time. The following will give you a detailed introduction on how to choose a shredder and the classification of shredders.

1. The origin and function of the shredder
The main function of the shredder is a device for coarsely shredding and reducing the weight of large recyclables. When the shredder has not been widely used, the main method for customers engaged in the recycling industry is to use the shredder. Here is another topic to be introduced, the difference between a shredder and a shredder. The crusher crushes materials by means of high speed (usually between 400~500rpm) and high inertia impact. This equipment has the characteristics of high production capacity, low production cost and simple operation when crushing light materials and small materials. However, for high-hard materials and bulk materials, if only relying on the characteristics of high speed and high inertia impact, the bulk materials cannot be broken. High-hard materials and bulk materials need to use equipment with relatively low speed and high torque for coarse crushing. The way to increase the torque is usually achieved by reducing the speed of the high-power motor by reducing the speed of the reducer and increasing the torque. This is why we see that every shredder is driven by a reducer, and the shredder is only driven by a pulley and a counterweight wheel.

2. three classification methods of shredders

a. According to the number of shafts, it can be roughly divided into: single-shaft shredder (1 shaft), double-shaft shredder (2 shafts), and four-shaft shredder (four shafts).

b. From the drive mode, it can be divided into two types: electric motor drive mode and hydraulic motor drive mode.

c. According to the types of materials that need to be shredded, this classification method is relatively complicated. Xinbei Machinery roughly divides this classification method into the following categories:

① Plastic hard material shredder (such as: plastic pipes, plates, trash cans, plastic baskets, etc. surface are hard plastic),
② plastic soft material shredder (such as: film, ton bags, woven bags, packaging bags Plastics in a soft state)
③ metal shredder (a shredder that can shred metal),
④ a branch, trunk, and straw shredder (a shredder that can shred straw and branches).

3. How to choose a shredder
After understanding the classification of shredders, how do we choose a shredder? First of all, when choosing a shredder, it is necessary to understand the purpose of using the shredder, whether it is for weight reduction or coarse shredding, and at the same time to understand the state of the material, and then combine with professional manufacturers to accurately locate the type and capacity model of the shredder.
For example, if I need to shred large-diameter pipes, some manufacturers in the market recommend single-shaft shredders, some manufacturers recommend dual-shaft shredders, and even recommend four-shaft shredders. At the same time, there is also a recommended crusher. We first solve it by the elimination method. First of all, the crusher is definitely not good. Above we talked about the structure principle of the crusher and the shredder. Everyone already understands why the crusher can't. The structure of the four-shaft shredder is mainly suitable for thin-walled hollow containers, which can also be negated here.The remaining two-shaft and single-shaft shredders are compared. The driving method of the double-shaft shredder is two motors and two shafts. The working principle is to shred the material by rotating the blade and the blade. This method must be that the material thrown in is within the range of the motor torque. It can only be cut inside, otherwise there will be stuck, frequent forward and reverse such problems, large-diameter pipes usually have high hardness and strong bearing capacity. If you want to use the double-shaft shredder to shred large-diameter pipes, you must use a large motor power to achieve the best effect. The driving method of the single-shaft shredder is a single-motor structure. The working principle is that after the main shaft rotates, the oil cylinder drives the silo to push the material to the rotating main shaft to shred the material. At the same time, the contact area between the material and the main shaft is controlled by the current. When the current is too high, the silo automatically retreats to separate the material from the main shaft. This structure has the characteristics of low motor power and flexible use, regardless of the amount of material thrown in. Whether the main shaft is applicable or not . Completely automated operation to save energy and labor costs.

4. Summary
Regarding the selection of the shredder, it is necessary to select the type and model of the shredder according to the characteristics of the specific materials and its own output requirements, and professional technical manufacturers can be consulted.

Q WASTE TIRE SHREDDER PRICE

A
The factors that determine the price of waste tire shredder are mainly from 1. The type of shredder. 2. Output. 3. Equipment quality. Look at these three aspects.

Double Shaft Shear Shredder

1. the type of shredder
Both the dual-shaft shearing shredder and the four-shaft shredder can shred waste tires, but the effect is different, and the price is also different. Generally speaking, the four-shaft shredder is better than the double-shaft shredder. more expensive.

Four Shaft Shredder

The main difference between the two-shaft shredder and the four-shaft shredder is in the application scenarios and materials. The applicability of the two-axis is wider, and the four-axis is more precise and dedicated. The four-axis is mainly for large hollow containers, such as blue barrels and IBS barrels. The dual-shaft shredder is mainly for small hollow industrial solid waste, tires, domestic waste and other materials. Use a large hollow barrel for comparison. If you use a dual-shaft shearing and shredder, you need to cut or flatten it. With a four-shaft shredder, you can directly shred it, because the four-shaft shredding and grabbing angle is more bigger. Secondly, the four-axis can be used for multiple shearing, and the dual-axis is basically one shearing. Therefore, from the perspective of the shredder effect, the size of the material after shredding by the four-shaft shredder will be smaller than that of the double-shaft shredder. complex materials. Most of the four-shaft shredders are used for shredding hollow materials.

2. Capacity
The same brand, the same type of shredder, the higher the capacity, the more expensive the price. The factors affecting the capacity mainly include the following aspects: the rotating diameter of the shredder tool, the material of the tool, and whether the transmission structure is a hard tooth surface reducer or a planetary reducer. Equipment with high output, stable operation, many processing steps, large working condition selection, power coefficient and reducer safety factor.

3. Equipment quality
The quality of the equipment is mainly from the design selection, materials and accessories. Good brand, all plates are thick, accessories and knives are of good quality. The material of the tool is the most important part of the price of the whole set of equipment. Good material selection has a long service life and can handle complex types of materials, so the price will be more expensive.

Therefore, when choosing a waste tire shredder, you should combine your own actual situation. If you need to shred a single waste tire, it is more appropriate to choose a dual-shaft shearing shredder. For other larger hollow materials, choose a four-shaft shredder.

The price of shredders varies widely. Even the prices of shredders of the same specification vary widely from different manufacturers. In addition to the differences in materials, there are also differences in the manufacturing process. Choose reasonable working conditions according to different types of equipment. The matching factor is also crucial to ensure the long-term stable operation of the machine. That's why we choose equipment from well-known manufacturers.
Q WHAT ARE THE CHARACTERISTICS OF THE FOUR-SHAFT SHREDDER? WHICH SCOPES ARE APPLICABLE?

A
Differential operation between four axes, with functions such as tearing, squeezing, and occlusion. The electrical parts are programmed and controlled by Siemens electrical components, with functions such as automatic detection of overload protection . . .

Differential operation between four axes, with functions such as tearing, squeezing, and occlusion.

The four-shaft shredder is suitable for the refinement of various large-volume and difficult-to-break materials, and has the advantages of uniform discharge and controllable size, such as: used for shredding plastic barrels, plastic frames, plastic bottles, metal cans, metal barrels, Materials such as woven bags, refrigerators, circuit boards and cartons. High efficiency, low speed, high torque, low noise. The four-shaft shredder has the characteristics of strong wear resistance and high strength.
Q THE DIFFERENCE BETWEEN SHREDDER AND CRUSHER

A
When we were doing market research, we found that there are many people who want to enter the recycling industry. They think that a shredder is a crusher. Although there is only one word difference between the two in name, there is actually a big difference between the two. It is the words "tear" and "broken" that describe the main difference between shredder and crusher. Let's discuss the difference between the two in detail and how to choose the right equipment for your production needs.

1. What is a shredder
The shredder is an environmentally friendly device that can shred waste plastics, waste plates, waste tires and other waste recyclable resources for recycling. In terms of comprehensive utilization, it is a device that turns waste into treasure. The working principle of the shredder is also different from that of the shredder. The shredder is a machine with a low-speed and high-torque knife roller. It can decompose large objects into irregular small pieces, and the shredded small pieces are small. Blocks are usually 20mm–200mm or larger in size. It is a professional machine for shredding solid waste. It usually includes several common specifications such as single-shaft shredder, double-shaft shredder, four-shaft shredder, horizontal shredder, and plate shredder. The shredder uses a tool to cut, shred, and tear the material to shred the material. It is generally used to process unprocessed raw materials or scraps. A representative example is to shred plastic or rubber scraps and use them as raw materials to melt and granulate them to remake plastic bottles, tires or trash cans. The shredder is used in the plastic recycling industry, and is often used for the shredding of waste large-diameter PE plastic pipes, bundled plastic films, large piles of plastic sheets and machine head materials.

Double Shaft Shredder

2. what is a crusher
Crusher generally refers to the equipment for crushing stones in mines. It is two different concepts from what we call the crusher in the plastic recycling industry. The crusher in the plastic recycling industry refers to the waste materials passing through high-speed rotating blades The way to chop into small particles becomes a raw material that can be reused! The principle is to chop the material by mutual shearing with the high inertia impact matching and the sharp-edged rotating movable knife and the fixed knives fixed on both sides of the rotating shaft. Generally speaking, large-sized materials (such as large pipes) are first torn into blocks with a shredder, and then broken into small pieces by a shredder, which are used as raw materials for reprocessing.

3. The difference between shredder and crusher
First of all, the size of the material targeted by the shredder and the shredder is different. The shredder is to tear the material into irregular 20mm-200mm or even larger size blocks. The crusher is to further crush these block materials into small pieces below 20mm, so as to achieve the conditions for further processing, such as granulation after cleaning.
Secondly, the principle is different, the speed of the shredder is very slow compared to other shredders. The principle of the shredder to shred materials is mainly to tear, cut and shred various materials by low speed, large torque, and the speed difference between the shafts. The crusher uses a high-inertia impact matching and a sharp-edged rotating movable knife and a fixed knife fixed on both sides of the rotating shaft to cut the material into pieces by mutual shearing.
Finally, most of the shredded materials are stubborn materials with high strength, large size and strong load, and most of the materials processed by the shredder are conventional materials with low load and small size. From the point of view of use, shredding has the advantages of safer, less manual operation and low noise. Crushing is relatively noisy and requires more manual operation and maintenance.

4. How to choose correctly
How to choose the right equipment, we must first clarify two questions: 1. What material do you need to crush and what is the original form of the material? 2. What particle size (size) do you want the material to be crushed into? These two factors will determine your investment cost as well as your production efficiency. For example, are your materials plastic, paper, rubber, PVC, old tires, household waste, sheet metal, large furniture and sofas, fruit and vegetable waste, iron stamping scraps, machine head materials, medical waste or something else? What are you going to do with the scraps after crushing? How big do you need to break the material, like 100mm, or 10mm, or less? With the answers to these questions clear, you can choose the right machine based on some simple criteria.

5. Common uses of shredders and crushers in the recycling industry include
1. Reduce the space occupied by garbage, thereby reducing the cost of domestic garbage consignment.
2. Tear waste such as old tires into pieces for fuel or filler.
3. Break paper or confidential documents to make them unrecognizable and unreadable
4. Shredding waste plastics before cleaning and regeneration.
5. Destruction of counterfeit and defective products and electronic hard drives
6. Volume reduction of bulky waste and industrial hazardous waste.
7. Pretreatment and crushing of fruit and vegetable waste and organic waste in the early stage of landfill fermentation
8. To prepare for the next process, the material needs to be refined.
