Product Description
Grain Screening Machine Circular Rotary Vibrating Sieve Screen
Introduction
Rotary vibrating screen is designed as a high-precision screening machinery, it is composed of a upper cover, a screen box, a base and a vertical motor with eccentric weight installed at two ends. Rotary vibrating screen can be produced in horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight. Diameter also can be ranged from 400mm to 2000mm, with single or multiple screening decks, material can be total carbon steel, total stainless steel or material contact parts are stainless steel according to different product.
Working Principle
The vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. The direction of the eccentric weights can change its rotational mode,rotation of the upper weight creates vibration in the horizontal plane, which causes material to move across the screen cloth to the periphery,while the lower weight acts to tilt the machine, causing vibration in the vertical and tangential planes. The trajectories of materials on the screen can be changed by adjusting the phase angle of upper and lower weights.
Application
Rotary Vibrating Screen is widely used in many industries, covering food, chemical, ceramic, metallurgy, pollution treatment and so on, dealing with various kinds of materials.
Advantages and Features
1.Various material separation range- power or particle,wet or dry, heavy or light,coarse or fine, hot or cold.

Performance and Features
| Low energy consumption, low noise |
| High screening accuracy, large capacity, simple structure |
| Fully enclosed structure, good sealing, prevent dust spillover, automatic discharge, more suitable for assembly line work |
| Screen body parts are used copper plate and section welded together (part group between body for bolt connection) overall stiffness is good, strong and reliable |
| Unique design of screen structure, convenient and quickly to change screen (only 3 to 5 minutes); And her mother screen fully supporting the fine screen, so fine screen can be long life, so as to reduce the consumables cost of the fine screen; In addition this design allows to using all kinds of screen (nylon, special dragon, PP network) |
| The design of the machine is exquisite and easy to assemble; one person can operate the machine |
We mainly provide the following vibrating screens (screening equipment)
| PSZS gyrtory screen |
| YA/YK circular vibrating screen |
| ZS linear vibrating screen |
| GTS trommel screen |
Troubleshooting
| When rotary vibrating screen running material does not automatically discharge: |
| The angle between upper and lower counterweight greater than 90 °. |
| The upper and lower counterweight angle adjust reversing. |
| There are abnormal sounds when rotary vibrating screen running: |
| Check if the screws clamps are loose and if the clamps fit for the screen plate. |
| Check if the perforated screen plate damaged, or whether the grid is put in the groove. |
| Check whether the base is durable, if the exciting force is too strong and unstable should reinforced. |
| Whether there is breakage of the spring. |
| The motor mounting bolts loose or damaged. |
| Whether the body have some contact with other objects. |
| The motor is running abnormally or stop running. |
| Check whether the power supply lack of phase or power outage. |
| Check whether the motor coil is burn-out. |
| Whether the lubricant inject too much. |
Lastest News about rotary vibrating screen
Last week,PK Machinery dispatched its first batch of cargo from Qingdao port to Johannesburg port .
The equipment,rotary vibrating screen is used for sieving attapulgite clay with 800kg/m3 density and 8% moisture,the total output is 2 tons per hour.Meanwhile,our client requires 4 lays,mesh sizes are:4mm,2mm,1.18mm,0.5mm.
After knowing well of client's requirement,PK engineer configured model XZS-1500-4,which can achieve the expected output,besides,we also suggested some screen mesh and vertical motor as spare parts,client spoke highly of our considerate advice and expressed his wish to cooperate with PK Machinery again.
