Vibrating screen springs are mainly divided into steel springs, rubber springs and composite springs. So which vibrating screen springs to choose, and how to choose vibrating screens? Xiaobian will introduce you next.

Steel springs, as the name implies, are mechanical parts made of metal steel that use elasticity to work.
Advantages: It has long service life and is not affected by ambient temperature.
Applications: vibro sifter, stainless steel vibrating screens, light linear vibrating screens, small heavy vibrating screen, probabilistic screens, etc.
Model Inner diameter D
The rubber spring is a high-elastic body. The material is made of ordinary rubber. It is a spring that uses rubber elasticity to cushion and absorb shock.
Advantages:There are excellent cold resistance, air tightness, water resistance, electrical insulation. There are many types of rubber springs in Dahan, and they can be customized as needed.
Applications: Light linear vibrating screens, stainless steel vibrating screen, vibrating feeders, vibrating screen, YA/YK series vibrating screens, etc. Springs of this type are also used in vibration platforms with a bearing capacity of more than 1 ton.

The composite spring is an elastic body composed of a metal coil spring and a rubber composite. It combines the advantages of a metal spring and a rubber spring, and overcomes the shortcomings of both. The shape and mechanical properties are stable, and it can withstand loads and large deformations. Good vibration reduction effect
Advantages: The shape of the composite spring is not limited and has a large elastic deformation.
Application: Suitable for large-scale vibration equipment in mining, coal, metallurgy and other industries.
After selecting the material of the vibrating screen spring, it is also important to determine the number of vibrating screen springs. The effective damping device needs to calculate the vibrating screen according to the specifications, output, excitation force and dynamic and static load parameters of the vibrating screen. The number and distribution of springs, if you have such requirements, you must consult a professional vibrating screen manufacturer to obtain professional advice, otherwise the expected shock absorption effect may not be achieved.
The above is an introduction to the vibrating screen spring. If you have other needs, you can always consult us.
1. When designing, the appropriate rubber material should be selected according to the screening material, environment and conditions, as well as the specific gravity of the material itself, static electricity, etc.
2. Attention must be paid to the bonding degree of rubber and metal to avoid stress concentration at the bonding surface;
3. Technically, for shear deformation isolators, in order to improve the service life, an appropriate precompression is usually given in the vertical shear direction, the stiffness in the compression direction becomes harder, and the stiffness in the shear direction becomes soft;
4. If there is resistance, energy must be consumed. This part of the lost energy is converted into heat energy, and rubber is a poor conductor of heat. In order to prevent the performance of the rubber vibration isolator from being affected by excessive temperature rise, the rubber vibration isolator should not be made too large. Structurally, measures that are easy to dissipate heat should be taken, or natural rubber materials with less heat generation should be selected. Because the rubber vibration isolator can convert part of the energy into heat energy, which reduces the vibration energy and achieves the purpose of vibration reduction, the rubber vibration isolator is often called a shock absorber.
5. Regularly maintain and replace the shock absorbing spring, and the vibration isolator should avoid working under tension for a long time.
There are several types of Feeders. Choosing the right one for your application should be based on the characteristics of the material to be handled and the required capacity.
Selecting a Feeder for a particular situation is not always simple, however, especially if more than one satisfactory solution appears possible.
Some of the criteria for choosing the proper Feeder includes:
First, consider the gradation of the material the Feeder will handle. Be sure to include the largest lump size (even if it is less than 1% of the total gradation) as well as the smallest particle size in this analysis.
Next, determine the capacity of the Feeder, taking into account the design maximum, normal and minimum capacities. Determine if the feed rate is going to be fixed or variable.

Consider the material the Feeder will process. When sizing a Feeder, it is important to know the following information about the material:
You'll also want to consider if the material is free-flowing, sticky, wet or dry.
Consider the material temperature and the ambient temperature range at the operation site.
If the material is to be scalped by the Feeder, consider the desired size of the material and what percent is to pass the opening. Determine if there is one scalping size or multiple sizes.
Consider how many hours and days per week the Feeder will be operating.
Determine if the Feeder is going to be installed on a portable or stationary plant, and know if weight and size of the Feeder will be a factor.
Consider the space that is available for the Feeder. If this is an underground mine, know if there is a limit to the size and weight that can be transported in the mine shaft or tunnel. Also consider how much space is available for maintenance.
Site amentities are another important aspect to consider when sizing a Feeder. Be sure to consider the type of power available at the site (line or generator), and if you prefer a hydraulic or electric drive. Also take into account the elevation and climate of the site.
Consider how the Feeder will be loaded (haul truck, wheel loader, conveyor, crusher, etc.), and know the size of this piece of equipment.
Consider the type of equipment the Feeder is charging (truck, train, conveyor, crusher, screen or scalper). Also consider the type and size of crusher or downstream equipment the Feeder is planned to feed.
The types of Feeders include:
The Apron Feeder is higher on capital investment and higher on investment returns. It is the most robust Feeder and is commonly used in the mining industry under 24/7 operation with years between maintenance periods.
Apron Feeders are used for:
Belt Feeders are generally used for fine material applications. These are flat belt conveyors supported by closely spaced idlers and driven at the head pulley.
Belt Feeders are used for:
These Feeders are a reciprocating tray-type feeder. The reciprocating motion is produced mechanically by a crank or eccentric and connecting rod, or hydraulically operated by a hydraulic cylinder. The Feeder discharge occurs during the back stroke of the plate ' no material is discharged in the forward stroke.
Plate Feeders are generally installed under a bin and are used for:
Vibrating Grizzly Feeders are smaller in size than Apron Feeders and are used where pre-sorting is required before a crusher. Material is conveyed along the pan of the Feeder as a result of the vibrating motion imparted to the particles. This vibration pre-sorts the material, passing the fines to the bottom. The fines can then be pre-screened before a crusher, thus reducing the required capacity and wear.
Vibratory Feeders are used for:
These Feeders are lower on capital investment and lower on investment returns.
Material is conveyed along the Wobbler Feeder as a result of the rotating motion of the elliptical bars. This motion scrubs and pre-sorts the material, passing the fines to the bottom. The fines can then be pre-screened before a crusher, thus reducing the required capacity and wear. The Wobbler Feeder is high on capital investment and medium on investment returns.
Wobbler Feeders are used for:
Wobbler Feeders are not used for any round or slick material such as gravel or coal.
