The three-dimensional rotary vibrating screen uses an upright motor as the vibration source. An eccentric hammer is installed at the upper and lower ends to convert the rotary motion of the motor into a horizontal-vertical-tilt three-dimensional motion. Upward involute motion has the advantages of long trajectory of material running and high utilization rate of sieve surface. It can perform fine screening and probability screening of materials.

By changing the included angle and mass of the two eccentric blocks above and below the vibration motor, the vibration motor can drive the device to generate vibration forces of different magnitudes, thereby changing the vibration amplitude in the horizontal or vertical direction, and then changing the flow and efficiency of screening.

A vibrating screen is a necessary machine for mining and quarrying industries. In the quarrying field, the screening process always follows the primary and secondary crushing stages to divide rock material into more than three sizes from coarse to fine.

Actually, how many sizes of material do you want to get depends on how many screen decks you adding to the machine, which greatly improves the value of raw material. Besides, the vibrating screen also plays a key role in the ore mining industry where ore beneficiation process has strict requirements on the size of ore. For example, before entering a ball grinding mill, ores must get their size meet a ball mill opening size, and be not containing impurities with the help of a vibrating screen.

The working principle of a vibratory screen is quite simple, which makes it easy to operate. The crucial parts of the machine include vibrating screens, exciter, motor, screen decks, liners, and side plates.

Vibrating source comes from an exciter that transmits vibration to the screen deck by the V-belt, which makes material shaking and distributing evenly on the screen. During the process, the large size of material will stay on the top while the small and fine size material can go throughout the screen mesh to the bottom, then youll get different sizes of materials.

The vibration of screen is generated by an exciter which consists of housing, bearing, shaft and an eccentric mass. In-deep speaking, the motor passing the driving force to exciter by V-belt, and then eccentric mass rotating around the exciter shaft to create vibration.

The screening and frequency can be adjusted by changing the ratio of the V-belt sheaves. The high-quality exciter can performance a force output of 1000 KN, keeping excellent operational performance and economic efficiency.

The task of the balance wheel is to ensure centrifugal forces evenly distributing around the axis of rotation, otherwise, the unbalanced cause the pulley to vibrate thus leading to premature or even catastrophic failure.

An inclined vibrating screen is one of the most popular screening machines. The inclination of this type of screen is at the range of 15 to 30 degrees. Screening stroke can be adjusted by remove or add eccentric mass and is generally at 8mm to 12mm.

The inclined screen utilizes gravity to help material move downward. Besides, the circular motion also helps to separate coarse and fine material. This type of vibrating screen is often applied in stone crushing, sand making, ore processing, construction waste recycling, wet screening, and chemical fields.

The inclination angle of the horizontal vibrating screen is between 0 degrees and 5 degrees, almost parallel to the ground. It is equipped with a triple drive mechanism that combines advantages of linear and circular vibration types in elliptic vibration.

The triple drive mechanism can keep material moving horizontally under the help of linear vibration while avoid them plunging because of the circular vibration. A horizontal screen has a simple structure, reliable performance, and large capacity, and can overcome any condition. So, it is the most practical vibrating screen in the quarrying field.

The outstanding feature of a high-frequency screen is high frequency and low amplitude, which ensures a faster material speed thus greatly improving screening efficiency. It is perfect for screening feeds containing solid and crushed ores down to approximately 200m in size.

It is mostly used in dehydration wet screening in which a filtering layer on the screen surface can block the passage of fine material thus reducing the loss of solid materials in water and improving the recovery rate of solid. It is applied for screening and separating iron ore, tin ore, tungsten, tantalum, and niobium, etc.

factors affect screening efficiency of vibrating screen - xinhai

factors affect screening efficiency of vibrating screen - xinhai

Screening effect and efficiency of the vibrating screen can affect the output and production efficiency of the whole production line. Here are some reasons that affect the screening effect and efficiency of vibrating screen.

Experiments show that adding surface-active material to water containing material can increase the activity and dispersibility of materials, and improve the screening condition. Besides, using the vibrating screen deck that is made up of non-hydrophilic materials also can improve the screening efficiency.

The soil is easy to knot and lock the mesh in the screening process. Clayey materials and viscous materials can only be screened with large mesh in some special cases. Wet screening is spraying water on the material that is moving along the vibrating screen deck, and pre-desliming before screening.

The particle characteristic mainly refers to the content of various grained materials that have a specific influence on the vibrating screening process. When the difficult screening material is much more than other fractions, the screening process is better. The particle characteristics also include the shape of particles. It is easier to screening for those particles who have close three-dimensional sizes, such as spheres and polyhedrons. In other conditions, it is more difficult to screening for those particles with large different sizes, such as slice, strip and weird shape.

There is no effect on the screening effect if all particles are the same density. However, if the density of coarse and fine particles are different, the situation is totally different. If the coarse-grained density is small, then fine-grained density is large. In contrast, coarse-grained density is larger and fine-grained density is small.

Movement type of vibrating screen deck is related to the looseness of the oversize material layer and the speed, direction and frequency of vibrating screen motion. In the vibrating screen, movement type of screen deck is divided into several kinds of forms: circular vibration, linear vibration and elliptical vibration. Xinhai has developed a series of vibrating screens with high screening quality, such as circular vibrating screen, auto centering vibrating screen, linear vibrating screen.

In general, the screen width directly determines the processing capacity of the vibrating screen. The wider the screen, the larger the processing capacity. The screen length determines the screening efficiency. The longer the screen, the higher the screening efficiency. When the screen length reaches a certain size, the screening efficiency will be rarely increased, or even no longer increases. And if you increase the screen length now, only the size and quality of screen are increased.

Screen slope has a great influence on the screen strength. The larger the screen slope, the smaller particle size, the smaller the screen slope, the larger particle size. In order to exclude oversize material easier, sometimes the screen deck should be installed obliquely. The larger slope, the faster the material layer moves on the screen deck, the greater the productivity. But the time that material stays on the screen deck is shortened, which decreases the screen-penetrating probability and reduces the screening efficiency.

The larger screen, the higher unit area screening efficiency and the higher screening efficiency. In general, the larger the mesh size, the higher porosity of the screen. When the mesh size is certain, the larger porosity of screen is more beneficial to the screening of vibrating screen. However, but the porosity of screen is often limited by screen strength and service life.

For certain screen and raw materials, the operating condition mainly refers to the quantity and mode of feeding. Continuous and even feeding is the best feeding method. In addition, please timely clean and maintain screen deck, which is also conducive to screening effect of the vibrating screen.
