Why should the shredder blades be tested

Why should the shredder blades be tested? In terms of the wear form of the grinder blade, it can be divided into two categories: wear and crushing;

One is the continuous and gradual wear of the Shredder Blades

Second, it includes plastic fracture and brittle fracture, such as broken edge, broken fracture, spalling, crack fracture and other forms.

The commonly used inspection methods for the wear of the Shredder Blades can be divided into two types:

1、 Direct measurement method of Shredder Blades; It is to measure the wear of the Shredder Blades directly or through the change of the workpiece size in the non cutting time.

2、 Indirect measurement method of Shredder Blades; It is to determine the wear of the Shredder Blades by measuring the physical quantities related to the Shredder Blades during cutting, such as the chip force, vibration and noise, cutting temperature, and the change of the early degree of the machined surface.

If the blades of the crusher and the grinding groove are excessively worn, it will also directly lead to the failure of the crusher blader to give full play to their performance. In particular, the working strength of the blades of the plastic crusher is greater than that of the blades of the coal gangue crusher and the shale crusher, and the loss is more obvious. Once the parts are excessively worn, the production capacity cannot be improved.

Therefore, when the operator of the Shredder Blades finds that the blade enters the state of excessive wear, the Shredder Blades should be replaced in time; To deal with the wear of the Shredder Blades in a scientific way to ensure the continuous and efficient grinding production. It will also cause different damage to other parts!
