What's the Special Role of Vibrating Screen Bouncing Ball?

 When the vibrating screen works, have you ever noticed that the bouncing balls beat up and down on the sieve mesh? Why this phenomenon occurs on the sieve mesh? What's special role of bouncing ball? Today we will take a brief look.
These bouncing balls are an essential part of vibrating screening machines.Its role is beating the sieve mesh up and down avoid adhesion material blocking the sieve mesh which can improve screening efficiency and accuracy.

Bouncing balls are generally divided into different diameters: φ10, φ15, φ20, φ25, φ28, φ30, φ40, φ50, φ60 and so on, commonly used ones are φ25 and φ28 , φ40, φ50and φ60 mainly used for mine vibrating screen.
According to the material,bouncing ball can be classified into several types: rubber ball, silicone ball, PTFE ball bouncing, according to different materials of bouncing balls, the application and function is also different.
Natural rubber bouncing ball：it is suitable for general material screening process;
Silicone bouncing ball：good elasticity., mainly used for food, medicine and other materials screening;
PTFE bouncing ball : It can soak in the oil , mainly applied to oily liquid materials screening.
The bouncing balls should be selected based on different material properties to meet customer requirements in different conditions. Though bouncing ball is a small accessory, it is the key to solve the problem of screening.

The difference between the Conical self-aligning roller and the Friction transfer roller

Tapered self-aligning roller is similar with Friction self-aligning roller in structure which are mentioned when introduce the belt conveyor, their purpose is protecting belt and preventing belt deviation. However, in the process of actual use, there is a big difference between them.
The main difference:

1.Stability performance: these two kinds of roller have their own advantages and disadvantages. Tapered self-aligning roller provides a more stable transport environment for belt and material, but since the tapered roller with a certain angle, if carries the material for a long time, it will increase the radial offset of roller. While friction self-aligning roller has a stable structure so that it can carry material for a long time and won’t be influenced. but there is a certain angle between belt and roller due to design of friction pulley, the joint degree of friction self-aligning roller is lower than tapered self-aligning roller, which will reduce the stability performance of belt conveyor.
2.Friction coefficient: concerning this aspect, tapered self-aligning roller has advantage over the friction self-aligning roller, tapered self-aligning roller has a special body design of roller, it could extremely increase joint degree of belt and roller to make the belt adapt to tapered roller, it also greatly reduce the force of friction.

3.Sealing Performance: the sealing performance of friction self-aligning roller is better than tapered self-aligning roller, the friction one adopts the design with independent installation of the friction pulley to promise a good sealing performance, however, because tapered self-aligning roller has a different diameter of pipe, it increase the difficulty of seal, meanwhile, performance of seal is also reduced.
4.Production cost: the structure and technology of tapered self-aligning roller are much simpler, so the cost is low, but if in the long run of using, the friction self-aligning roller is more stable and durable.
