5 Vibrating Screen Common Problems And How To Solve? | M&C
The circular vibrating screen uses the inertia exciter to produce vibration. The main shaft fixed on the screen box is driven by the motor to rotate at high speed, and the eccentric body installed on the main shaft rotates with it, generating centrifugal inertia force, so that the screen box that can freely vibrate will produce vibration similar to the circular track.
Aug 14, 2020· The bearing of the main shaft is installed on the screen box and is driven by the pulley to rotate at high speed. The eccentric counterweight plate is installed on the main shaft and generates centrifugal inertia force with the rotation of the main shaft, so that the screen box forms an approximate circular orbit vibration.
Vibrating screen is a rectangular single-, double-, and multi-layer, high-efficiency new screening equipment. It does circular trajectory, so also known as the circular vibratory screen. The screen machine is ideal equipment in rock crushing and screening plant. JXSC vibrator screens adopt the cylindrical eccentric shaft exciter and the partial block to adjust the amplitude.
What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.
Inclined screen. Vibrating inclined screen is the most popular types of vibrating screens. The screen fix to the tilted frame at an angle of 15 to 30 degrees. The inclined screen is usually designed in a multi-layer structure and can be classified into 2-5 grades. And the screen can be adjusted to provide overall performance and efficiency.

High frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200m in size, and are applicable to both perfectly wetted and dried feed.
The Horizontal Vibrating Screen: 840 rpm , 1/2 stroke at 45°. Each has a .063 dia. wire screen with 1/8 clear opening, moving under a particle travelling at an assumed 20 fpm, for A, 40 fpm for B., 80 fpm for C, and 60 fpm for D. Omitting details
The distance between the bearings is 3 metres, and the vibrating screen structure is made of welded and bolted steel parts. Shaft deflection and misalignment of supports under load require bearings that can compensate for misalignment. Spherical roller bearings are selected for this new vibrating screen , which is the typical solution. They can carry high loads and accommodate misalignment between the inner
Exciters are the main vibration source of the screens. They generally comprise a housing, bearing, shaft and an eccentric mass. The vibration results from the rotation of the eccentric mass about the exciter shaft. Generally, power is transmitted from the drive motor to
main shaft. For materials that are difficult to screen, the circular vibrating screen can reverse the main shaft so that the vibration and the material keep moving in reverse, which can reduce the speed of material movement along the screen surface to improve screening efficiency.
The main shaft is connected to the motor by a flexible coupling, and the screen frame is supported by a spring; the utility model has the advantages of simple structure and good practical performance. The Working Principle of Vibrating Screen. The slurry flows into the screen frame from the feed box, and the coarse impurities in the slurry are screened by the high frequency vibration of the screen frame.
At the same time, because the main shaft (eccentric shaft) repeatedly compresses and expands the medium in the closed cavity in the process of rotation, it not only makes the medium in the closed cavity produce a relatively large extrusion force, but also causes the temperature of the medium to rise, which is transmitted to the bearing of vibrating screen, resulting in the bearing temperature rising higher.
The function of a vibrating screen is to sort particulate material made up of a distribution of sizes into specific size groupings. Vibrating screens generally handle particles of size between 5 mm and 250 mm. They are found in a variety of industries and in a range of processes. Its Main Elements: A vibrating screen consists of three main
Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. Its an environment where equipment failure is often accepted as a cost of doing business.
Vibration frequency, screen inclination of the vibrating screen. published date: 04-27-2019. Vibration characteristics include vibration frequency, amplitude, vibration direction angle, and screen inclination. If these parameters are set incorrectly, it will affect the working efficiency of the vibrating screen. The correct way is: 1.
The main shaft group is the main component of the vibrating screen, which is mainly assembled from pulleys, balance wheels, eccentric shafts, bearings, bearing housings, and housings. It Multi layer silica sand vibrating screen
The Mining Vibrating Screen of Winner Group is Mainly Used for Screening and Sorting of Coal, Sand, Stone, Gold, etc.
Jul 22, 2020· The circular vibrating screen is also called a single-shaft vibrating screen because the exciter is a shaft and uses an inertial motor to work. The linear vibrating screen is composed of two shafts and works on the principle of vibration motor excitation, so it is also called double Shaft vibrating screen. 3. Hole blocking phenomenon
The vibrating screen uses the motor to drive the eccentric shaft to make the screen body periodically along with the direction of vibration force. The materials make circular movement on the screen to realize sieving. Features 1.It uses cylinder-type eccentric shaft and
