During the long-term operation of the screening machine, some components may become vulnerable due to wear, fatigue, and other reasons, and need to be replaced regularly to ensure the normal operation of the equipment.

1、 The vulnerable parts of the screening machine mainly include the following:

screen mesh

The sieve is one of the core components of the screening machine, directly responsible for the screening of materials. Due to continuous friction and impact between the material and the sieve, the sieve is prone to wear and tear, holes, and other issues. The durability of screens made of different materials varies. For example, metal woven screens are relatively strong, but they will gradually wear out when handling materials with higher hardness; Polyurethane mesh has the characteristics of good elasticity and wear resistance, but it may also experience aging and damage after long-term use.

Spring

Screening machines usually use springs to achieve vibration and improve screening efficiency. During long-term vibration, springs are subjected to significant stress and are prone to fatigue, deformation, and even fracture. Especially when handling large amounts of materials or working at high frequencies, the loss of springs will accelerate.

Sealing element

To prevent material leakage and dust flying, seals are usually installed at various connections of the screening machine. Seals are prone to wear and aging when in contact with materials and under the influence of vibration, resulting in a decrease in sealing performance.

Bearing

Bearings are key components that support the rotating parts of the screening machine. Under high-speed operation and heavy loads, bearings may experience wear and the lubricating oil may also deteriorate, thereby affecting the service life of the bearings.

2、 Replacement cycle of vulnerable parts:

The replacement cycle of the screen depends on multiple factors, including the properties of the material, the frequency of screening, and the material of the screen. Generally speaking, if dealing with materials with high hardness and large particles, the wear of the screen mesh will be faster and may need to be replaced every few months; For some finer and softer materials, the replacement cycle of the screen mesh may be extended to six months or even more than a year.

The replacement cycle of springs is usually around six months to one year. If the working environment of the screening machine is harsh and the vibration intensity is high, the replacement cycle of the spring may be shortened.

The replacement cycle of seals is relatively short, usually between a few months to six months. If there is obvious leakage or dust flying around the seal, it should be checked and replaced in a timely manner.

The replacement cycle of bearings mainly depends on the working time and load conditions. Under normal circumstances, bearings can be used for about a year, but if there are abnormal noises, heating, or other phenomena, they need to be checked and replaced in a timely manner.

It should be noted that the above replacement cycle is only a rough reference, and the actual replacement cycle needs to be judged based on specific usage situations. During the use of the screening machine, it is necessary to regularly inspect and maintain vulnerable parts, promptly identify problems, and replace them to ensure the normal operation and screening effect of the screening machine.
