In the tire crushing process, the heat and conflict that occur are the manifestations of energy. The heat and conflict caused by the high surface load and the high-speed sliding of the chips along the rake face put them in a very challenging machining environment. The size of the crushing force often fluctuates up and down, depending on different processing conditions (such as the presence of hard components in the material of the workpiece, or intermittent crushing). Therefore, in order to maintain its strength at the high temperature of crushing, it is required to have some fundamental characteristics, including excellent resistance, wear resistance and high hardness.
Although the crushing temperature at the workpiece interface is a key factor in determining the wear rate of almost all data, it is difficult to confirm the parameter values needed to calculate the crushing temperature. However, the measurement results of the crushing experiment can be considered as the basis for some empirical methods.
It can generally be assumed that the energy that breaks out during the crushing is converted into heat, and generally 80% of this heat is taken away by the chips (this share changes depending on several factors-especially the crushing speed). About 20 percent of the other calories are passed in. Even when crushing steel parts that are not too hard, the temperature may exceed 550 ° C, which is an acceptable temperature for high-speed steels without reducing the hardness. When polycrystalline cubic boron nitride (PCBN) is used to crush hardened steel, the temperature of the chips will generally exceed 1000 ° C.
Tire recycling machine is the same as other machines. It should be protected from moisture and water. The machine is made of iron and iron is afraid of water. Although there are paints on the outside, but many places inside are not painted, so pay attention to moisture and water.
At the time of processing the original data, we will find that the cool things are more easily shredded, the shred power is higher, and the quality is very good, but about wet things, such as the tire shedder about wet tires, the shred power will be Lower than monotonous tires. Because the wet materials are shredded together more briefly when they are shredded together, a certain amount of resistance will occur and affect the shredding effect. And processing these wet things for a long time will cause corrosion to the parts inside the machine, which will cause rust, and further affect the processing power.
Therefore, two points should be avoided. One is the processing of wet and watery materials for a long time, and the other is that the waste tire shredder is often exposed to rain. Even a simple machine like usual, such as a bicycle, will rust and be damaged under the rain for a long time, so avoiding water and water is the basic common sense to protect the machine. Assuming that the tire recycling machine is not used for a long time, lubricants can be applied to vital parts such as bearings to avoid moisture corrosion in the air.
