Owing to our immense experience and knowledge in this domain, we feel proud to extend to our noted customers the service of our resilient vibrating springs. Their durability is the result of the stainless steel tray which is attached to the Vibrating Feeder Springs. They effectively control the supply of powder, granules and lumps. Areas like mine, railway, constructing machines are comprehensively benefitted by this capable product of ours.
As we proudly own a place among the important manufacturers, wholesalers and suppliers of all types of industrial springs our clients enjoy best performance from our Vibrating Screen Springs. An added advantage of these springs is that they are fixed with stainless steel tray. The feed of powder, granules and lumps is regulated steadily by our proficient Vibrating Feeder Springs.
Spring System for Vibrating Screen Springs are used to convert the vibration from the drive to tray thus causing product to move. Springs come in a variety of materials, sizes and configurations. From thin sheets of fiberglass to dense rubber compounds to thick steel coils. Each material is designed for specific applications. In some applications, a combination of spring materials may be used. 1.Fiberglass Springs (or boards) The most popular spring configuration for light and medium duty applications. Fiberglass springs of varying lengths, widths and thickness are mounted on the moving mass of the drive and are attached to the tray or trough. Small electromagnetic feeders, light duty conveyors and most high precision vibratory equipment use fiberglass or multiple pieces of fiberglass as their primary spring action material. 2.Dense Rubber Springs Typically used on heavy-duty feeders and conveyors to provide stability and motion control between the drive and the tray. However, rubber springs are limited to use in environments below 120F. 3.Steel Coil Springs Commonly used in heavy duty and high temperature applications. These coils are effective in ambient temperatures up to 300F and offer low replacement cost. ------------------------------------------------------------------------- Henan Pingyuan Mining Machinery Co., Ltd is the most professional manufacturer of Beltconveyor, and Vibrating screen, Bucket elevator, Screw conveyor, Scraper conveyorusing the world's most advanced technology,we are willing to serve every company to meet your custom needs. our goal is "be the futureglobal leader of mining machinery industry". have any questions, please contact us without anyhesitation.

Poor motion in vibrating screens and feeders can occur for many reasons, but one is arguably the easiest to prevent and yet seems the least understood the adverse effect of support springs (the springs on which the machine sits) behaving differently from one side of the machine to the other. The motion of the equipment will vary between the left and right sides, increasing the internal stresses within the machine, reducing its service life. It will become a greater challenge to maintain.
What do support springs do? They allow free movement of the vibrating machine and isolate most of the units vibration from its supporting structure. Something that is not broadly understood, however, is that they also magnify the vibration of the machine. While typically only by a few per cent, this magnification (caused by a dynamic response of the screens mass combined with the springs) occurs at each corner and will only be equal around the unit if the compression on each of the springs is equal.
A difference in spring compressions (between the left and right side on the equipment) means a difference in the amplitude of vibration (from one side to the other), which leads to excessive internal stresses within the machine body that are different to those typically considered in the machine design. To worsen matters, a variation in spring compressions (ie spring heights) forces a slight twist into the machine, creating yet another dynamic response that contributes to these adverse internal stresses!
Following these guidelines will not only keep your machines running evenly by minimising the equipments internal stresses, it will also help maximise the service life of springs without compromising the health of the machine. The life of a set of springs is that of the one most stressed. Keeping the spring heights consistent means stresses in the springs will also be consistent. That means a longer service life.
As well as selling various components for screens and feeders, including different types of springs, businesses also offer the service of testing vibrating equipment to identify adverse motion, from an equipment longevity perspective, and ways to improve performance. When a machine is running unevenly, we need to look for the various causes.
If the springs are in good condition and their static heights are reasonably similar from one side to the other, it becomes easier to identify the cause of the adverse motion. If the springs are in poor condition and/or vary significantly in height (left to right), it can often mean an additional site visit is required before there can be recommendations to correct the units motion. This adds to the service and means the machine will run poorly for a longer period.
The three most common (but not the only) types of springs seen on sites, on vibrating screens and feeders, are steel coil springs, rubber springs and screen (or oscillating) mounts. Although they differ in their construction, they all perform the same function on vibrating equipment, and their behaviour is governed by their deflection from their free height when under the weight of the machines they support. In all cases, the laden height of the spring is simply the vertical distance between the surface of the mounting bracket sitting on top of the spring and the surface on which the spring is sitting.
The design intent for vibrating machines is for them to wear out after many years of reliable service, rather than fall apart due to fatigue. In many situations, regular consideration of screen and feeder support springs in a sites maintenance checks will make the difference between years of reliable service and premature failure.
