Working principle and maintenance of dual axis garbage shredder


The working principle of the dual axis garbage shredder is mainly achieved through the staggered installation of blades on two opposite rotating blade shafts. During the rotation process, these blades crush the material through the shearing action of the blade and the tearing action of the blade teeth. The main crushing method is the shearing effect between adjacent moving blade edges, while the secondary shearing method is the tearing effect of the moving blade teeth on the material.

In terms of equipment maintenance and instructions, the following points need to be noted:

Regular inspection of blades: Due to the wear and tear that may occur during use, it is necessary to regularly check the wear and tear of the blades. Once the wear reaches a certain level, it should be repaired or replaced in a timely manner to ensure the crushing effect and yield, and to avoid affecting the normal operation of the equipment.

Adjusting the blade gap: The size of the gap between the blades has a significant impact on the crushing effect and output of the equipment. Generally speaking, the gap size should be controlled between 0.1 and 0.2mm, and regular inspections and adjustments are needed to ensure the best crushing effect.

Lubrication and maintenance: The bearings, gears, and other components of the equipment need to be lubricated regularly to reduce wear and friction, and extend the service life of the equipment. At the same time, the lubricating oil should be regularly checked for condition and replaced or replenished in a timely manner.

Pay attention to electrical safety: During the operation of the equipment, attention should be paid to electrical safety to avoid short circuits, overloads, and other situations. The motor's overheat and overload protection functions should be regularly checked to ensure their normal operation.

Alarm function inspection: Additional functions of the equipment, such as bearing temperature monitoring, high temperature alarm, and non breakable object alarm reminder, should be regularly checked for their working status to ensure timely alarm and corresponding measures can be taken in case of abnormal situations.

The dual axis shredder has become an important tool for achieving waste reduction, recycling, beautifying urban environments, and improving the quality of people's living environment due to its wide range of applications, such as industrial waste, household waste, municipal waste, garden waste, medical waste, kitchen waste, biomass crushing, etc. Therefore, proper use and maintenance of shredders are of great significance in ensuring their normal operation and extending their service life.
