Advantages of using rubber springs in mine screening machines

Spring is an important part of the screening machine. It is not only used to connect the screen box and the bottom bucket or bracket of the screening machine, but also plays the role of shock absorption and crack prevention. Steel springs, rubber springs and composite springs are commonly used in different types of screening machines. There are three different spring forms, and rubber spring is the most commonly used spring type for mining screening machines.

Reasons for using rubber springs in mining screening machines

1. The layout of the mining screening machine is compact, and the rubber spring can effectively use the space of the machine;

2. There is no metal spring structure to block, and it can be flexibly made into different shapes and sizes;

3. The elastic coefficient of the rubber spring is small, and the elastic coefficient can be changed in a large range with the change of the hardness of the material. However, the situation faced by the mining screening machine is complex and changeable, and the elastic coefficient and the elastic coefficient can be flexibly changed within a certain range. Rigid rubber spring is an excellent choice;

4. The internal friction damping coefficient of the rubber spring is larger, which means that in the face of the stronger excitation force and material weight of the mining screening machine, the rubber spring has stronger pressure bearing capacity, stable amplitude and absorbs more gravity potential energy

5. The sound insulation effect is better than that of metal springs, and the price is lower than that of composite springs, which is the optimal solution for comprehensive consideration.

Insufficient:

The rubber spring has poor heat resistance, wear resistance and oil resistance. Therefore, when using the mining screening machine, it is necessary to pay attention to regularly checking the wear of the shock-absorbing rubber spring, so as not to affect the screening efficiency due to spring damage, resulting in machine damage or failure. It is a production accident or the like.
