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:
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 shredderAfter 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. SummaryRegarding 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.
