The working state of the vibratory separator effectively mimics the screening machinery of human manual movement and process. Its unique design cleverly combines the sieve (planar circular motion), the Dustpan (to, the parabolic movement), the material in the equipment to do the horizontal and throwing three-dimensional rolling movement, from the Center to the outer edge evenly dispersed, with the spiral movement to the axial propagation. When the spinning sieve works, the motor drives the Sieve machine to do the space three-dimensional curve, this curve is projected as a circle on the plane. The projection on both vertical surfaces is elliptical. Adjusting the eccentric speed of the motor can change the movement trajectory of the material on the sieve surface, so that the sieve body produces a flat vertical composite vibration, to achieve the purpose of screening.
The material is feed from the middle of vibratory separator, and the movement distance of the material on the screen is basically the same, which can guarantee a very accurate screening process. The radial angle and tangential angle of the spinning sieve make the material move involute on the screen, and its design allows the material to walk through the phase on a smaller area. For long roads, the mesh time of the material is longer than that of other types of sieves. Adjusting the radial angle and tangential angle can adjust the accuracy and yield of the sieve.

How to Adjust the Upper and Lower Weights of the Rotary Vibrating Screen
Rotary vibrating screen is a high-precision fine powder screening machine with low noise and high efficiency. It is a fully enclosed structure suitable for screening and filtering materials such as particles, powder, and mucus. It is widely used in fields such as traditional Chinese medicine and filtration. According to different applications, rotary vibrating screens can be divided into ordinary types, gate types, and edge added types.
Among them, the ordinary rotary vibrating screen is mainly designed for the screening operation of ordinary powder and small particle materials; Gate type rotary vibrating screens are commonly used for screening ultra light and ultra-fine materials. Users can perform long-term screening operations by controlling the opening and closing of the gates. This type of screening operation is commonly used in industries such as traditional Chinese medicine powder and pollen; The edge type rotary vibrating screen is a filtering screening equipment that increases the feed inlet on the basis of the ordinary rotary vibrating screen and is designed at a special angle to prevent liquid splashing. It has a wide range of applications in industries such as paint, water filtration, and pulp filtration.
Adjust additional weight blocks according to demand
Through observation, it can be found that an additional weight block is installed on one side of the upper and lower weights (upper and lower eccentric blocks) of the rotary vibrating screen, which increases the excitation force of the screen machine. Users can increase or decrease additional weight blocks based on the number of layers and material density of the screening machine, in order to achieve a more satisfactory screening effect.
Adjusting the phase angle of the upper and lower weights
Due to the non adjustable angle of the upper hammer of the rotary vibrating screen, the user needs to open the bottom bucket adjustment hole, loosen the fixing bolt of the lower hammer, and adjust the phase angle of the upper and lower weights in the opposite direction of the discharge port according to the trajectory of the screened material. Then place a small amount of material on top of the screen, run the screening machine, and check the movement trajectory of the material on the screen surface. When the processing parameters have achieved good results, stop the machine and tighten the fixing bolts to complete the adjustment work (remember to tighten the fixing bolts).
Rotary vibrating screens are comprised of components that move and vibrate during screening operations. Hence, there might be some parts that might have been displaced. Others might even need some repairs or replacements after a long time of use. Checking the level of oil, stroke length and angles, as well as the bolts joints should be conducted every week. Additionally, assessment over the condition of screening media, wear parts, and springs must be done weekly. Upon these checks, you can eventually point out if some parts need to be replaced, repaired, or tightened.
One maintenance tip that you can do with your rotary vibrating screen is to assess the condition of your bearings. Once you have found out that your bearings tend to overheat, produce unusual noise during operations, or obtain significant clearance between the outer ring and the rollers, then you have to replace them right away. Bearings tend to deteriorate pretty easily since they work alongside shock-type loads. The rotary motion of most bearings, likewise, can affect their longevity in the long run.
Just like the bearings, the screening media of your rotary vibrating screens tend to receive a lot of workloads. With continuous usage of rotary vibrating screens, some parts of it can eventually get damaged. All supporting bars of the media must be inspected for corrosion and visible damages. If you have spotted some warped or worn parts, then you must replace them as soon as possible. The capping/channel rubber must also be replaced alongside the screening media, ensuring that the screening process takes place optimally. All nuts and bolts that are integrated with the screening media must also be inspected and replaced whenever necessary. Tension plates or rails must also be replaced for appropriate tensioning.
Excessive heating and welding the screen body of the rotary vibrating screen is not recommended. However, there are cases where welding is necessary to keep the machine running before conducting maintenance. If welding is needed, you must assess and document first the reasons behind the occurrence of cracks before repairing them. You must also make sure that no elements will penetrate the surface of the bearings. Additionally, welding must be done on both sides of the plate.
