Introduction of Dewatering Screen

Have you felt very confused with wet materials put in the bag or other places?Today our dewatering screen will help you!
Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.

To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.
► Features:
   1. Low noise, easy to maintain
   2. Large capacity
   3. High screening efficiency
   4. Light weight, easy to disassemble and replace
   5. Stable structure and strong exciting force

► Advantage:
   1.Stable structure with strong exciting force
   2.High screening efficiency and low noise pollution created
   3.Durable and easy maintenance
   4.Materials that stuck at the screening mesh can easily remove
   5.Low energy consumption
   6.Large handling capacity.
   7.Light weight, easy to disassemble and replace

► Introduction and working principle:
Rotary vibrating screen is designed as a high-precision screening machinery. Round vibrating sieve is composed of vertical motor,and eccentric weight installed at two ends.We can produce horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight.Diameter can be ranged from 400mm to 2000mm, with single or multiple screening decks.
► Working Principle:

XZ Rotary Vibrating Screen is a vertical-motor system, with eccentric hammers being installed on top and bottom of the machine, where the motor acts as the vibratory source. The direction of the eccentric hammers may change its rotational mode either in horizontal, vertical and inclined movement onto the sieving screener surface. The trajectories of the materials on the sieving machine can be change by adjusting the phase angle on both top and bottom parts.

    Metallurgy mining industry: lead oxide, zinc powder, aluminum powder, iron powder.
Pollution treatment: waste water, waste oil, pig dried urine, dyeing wastewater.
Other industries: carbon black, pearl powder, light calcium, additive, etc..
 
rotary vibrating screen

Features
-Layers can be up to five layers
-Fully enclosed design,continuous operation,small volume and low noise
-Self-cleaning device(bouncing balls),avoiding blockage, mesh size can reach to 500 mesh ( 0.028 mm)
-High precision, high efficiency, powder, granule and mucus are applicable
► Advantage :
 


 1.Low energy consumption, low noise, 
 2.High screening accuracy, large capacity, simple structure. 
 3.Fully enclosed structure, good sealing, prevent dust spillover, automatic discharge, more suitable for assembly line work.  
 4.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.  
 5.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).

What should we notice when maintain the vibrating screen in summer?

In summer, excess temperature is a hidden danger of daily operation for vibrating screen, generally speaking, working requirements of the environment temperature is not more than 40 ℃, so during the daily operation of vibrating screen, what we should concern about is not only the process of production, but also the degree of temperature that the vibrating screen can bear.
For the outdoor working conditions, a anti-sunshine net or cover should be set up for the vibrating screen.
Long-time sun exposure not only make the machine easy to get aging, but also cause the vibrating screen can not work normally due to the high temperature which will affect the screening efficiency and quality, it will even lead to a serious component damage, such as the damage of vibration motor.


For the indoor working condition or vibrating screen works in an ore processing plant, please pay attention to the adjustment of the indoor temperature, as well as the ventilation and the permeability, generally, a good working temperature is not more than 40 ℃.
