Henan Pingyuan Mining Machinery will explain why choose rubber spring for circular vibrating screen. 1. It can produce various different shapes and dimensions of the rubber springs which is compact and space saving. 2. Rubber Spring is with rubber elasticity coefficient compared with metal product, and the hardness can be changed in a larger scope, so changing the rubber hardness can make different stiffness spring, that means the stiffness can be chosen with wide scope even the same shape of rubber spring. 3. In addition, rubber spring of circular vibrating screen can also accept with shear deformation and austerity deformation. 4. The internal friction damping of the rubber spring is much bigger than the metal spring, so the rubber spring of circular vibrating screen machine stops and passing through resonance section, the amplitude of rubber spring is smaller than the helical metal spring ,so we choose rubber spring due to stable amplitude and lower energy consumption. 5. Rubber spring transmission noise resistance is much bigger than the metal spring, so the sound insulation is better and working noise is smaller.

In its simplest form, the circular vibrating screen is a surface having many apertures, or holes, usually with uniform dimensions. Particles presented to that surface will either pass through or be retained, according to whether the particles are smaller or larger than the governing dimensions of the aperture. The efficiency of screening is determined by the degree of perfection of separation of the material into size fractions above or below the aperture size. Read more
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.

Vibrating screens operating principle: In screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably. The operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated. Nude packing, wooden case.

With the introduction of eccentric shaft vibrating exciter and particular block, the amplitude can be adjustable. (Note: According to different requirements of customers, our company applies vibrating screen with different specifications and vibrating modes.) Working Principle When vibrating screen works ,two motor with synchronous reverse rotation that will produces the vibrating exciter with vibrating force , making the screen body and screen with longitudinal motion ,thereby the material upper on the screen will have exciting force and move forward a range, to achieve a complete screening working . Models: The screen deck size could be customize-made There are single deck type and double deck type for option
A WIRE RANGE OF PARTS FOR YOUR SCREEN BOX Vibrating screens need to vibrate in a linear motion, the screens need to be correctly tensioned and washing requires proper nozzles. We offer a wide range of accessories for vibrating screens to ensure proper and safe operation.
Screen panels require proper tension and bedding to perform at their best with minimum breakdowns. Cappings act as a bumper between the deck and screen mesh. It is very important to fix the screen mesh tight to the deck as a lose connection will destroy the screen in a short period of time.
Rubber buffers are an important part of a vibrating screen. Screen operation should be strictly linear in line with the material flow and side movements should be minimised. Especially during start/stop operations, side movements increase as the screen passes through amplitudes close to its natural frequency and it resonates. Side rubber buffers prevent the screen from moving sideways.
While a large number of engineers try to minimise the vibrations in different applications, vibrating screen manufacturers try to make the best of it. Proper vibrating patterns are not possible without flexible mounts. Springs are the most common type of vibrating screen suspension. They are durable and easy to install and service.
Washing is one of the most important stages in aggregate and mineral processing applications. Generally, washing is performed by spraying water under pressure on the top of the material flow. Washing nozzles are special attachments to the pipes that spread the water over a wide coverage area. This water washes off the clay and dirt.
Declogging rods have been developed to further improve the self-cleaning properties of anti-clogging screens. Declogging rods bounce on the PU strips and create additional shock that helps to shake off stubborn sticky material from the panels. Declogging rods can be connected in multiple parts to completely cover the screen area.
