What Should Buyers Consider When Ordering Dewatering Screen ?
Vibrating dewatering screen is used to handle all kinds of slurry of machinery and equipment, and its role is to solid and liquid particles vibrating dewatering to achieve solid-liquid separation. The main components of vibration sieve dehydration include: dehydration sieve body vibration motor, beam and drive beam, plate and rubber springs.
Vibrating dewatering screen equipment selection process is very complex and must be combined with the actual production is determined by the parameters of the device
according to the actual situation tailor-determined parameters and the field. Selection of
parameters before determining vibrating dewatering screen, which is the initial part of the dewatering screen, there are some issues we need to be concerned about, such as
vibration sieve dehydration efficiency and maintenance costs.
1, vibration dewatering screen maintenance costs
Vibrating dewatering screen maintenance costs are issues that must be concerned about
the initial selection, good even sieve dehydration processing power, but the high running costs will reduce its price. Vibrating dewatering screen maintenance costs are mainly generated on the screen films, namely the purchase of replacement sieve.
Vibrating dewatering screen slurry treated with a lot of solid particles, the solid particles can cause wear of the sieve. When the preliminary selection sieve dehydration, should fully take into account the nature of the particle size of the processing of materials, but also to understand the vibrating dewatering screen structure is reasonable, parts replacement is convenient and easy.
2.The service on dewaterin screen suppliers of spare parts
Whether dewatering screen selection is successful, in the actual operation of the vibrating dewatering screen wear occurs, in particular sieve sieve dehydration such high-wear parts. Dewatering screen high level of service suppliers of spare parts, spare parts sufficient reserves, can significantly reduce the time cost of the purchase of spare parts, reducing production losses.

Basis Quality of hydrocyclone decide the practical application!
Basis Quality of hydrocyclone decide the practical application! The basic principle of the cyclone is to have a certain density difference of liquid - liquid, liquid - solid, liquid - gas and other two-phase or multiphase mixture under the effect of centrifugal force separation. The mixture to a certain pressure to cut into the cyclone, the cylindrical cavity produce high-speed rotating flow field. High density component of the mixture under the effect of the cyclone field while axially downward movement, the movement radially outward, reaching the cone segment downward movement along the wall by the bottom flow discharge port, thus forming the outer vortex flow field; the density of small components to the central axis direction, and is formed in the scroll upward movement in the axial center, and then discharged from the overflow port, so that to achieve the purpose of the two-phase separation.
Primary Classifying hydrocyclone is widely used for single-family daily processing capacity of 500 tons of all kinds of metal ore, non-metallic mineral processing plant, and some closed circuit ball mill grinding and classification constitute circulation. Cyclone according to different processing capability, a single arrangement can also be configured into groups. At higher concentrations ore, with higher efficiency and finer grading overflow fineness, even urged the overflow product, extension 5-10% higher efficiency than conventional spiral classifier conducive mill improve the utilization coefficient.

Analysis of internal and external structural characteristics of the hydrocyclone
Internally and externally, hydrocyclone product also catechism to face! Cyclone liner wear layers are made of corundum, high wear-resistant rubber, composite ceramics, KM ceramic composites, polyurethane, etc. depending on the material properties and working conditions. Also it is based on site requirements for the structure of the cyclone wear resistance of the components, in different parts of a cyclone liner wear different materials, in order to increase the overall service life of the cyclone, which over wear-resistant enamel lining material obtained very good results.
Outer swirl and inner Swirl:
Outer and inner Swirl is the main form hydrocyclone movement, they have the same direction of rotation, but in the opposite direction of its movement. Thick and heavy outer swirl carrying solid material from the grit discharge port for grit products; within the cyclone carry thin and light solid materials have overflow discharge port for overflow product.
Shunting:
To the two-phase fluid into the cyclone, due to the frictional resistance of its walls, part of which at first on another surface and then inward along the lower lid, and the downward movement along the outer wall of the vortex finder, and finally with the confluence of the inner cyclone overflow pipe overflow discharge port. This part of the lid is commonly referred to short-circuit the downstream flow, due to its direct access to the overflow product, without separation, and therefore directly affect separation.
Circulation flow:
From outside to inside spiral swirl vortex within the cyclone moved form of two-phase fluid, because the overflow of the overflow pipe discharging too late in its entirety, part of the fluid which is not discharged from the overflow of the cyclone vortex the space between the pipe and the wall, as a top-down bottom-up and then a circular motion to form a recycle stream.
Zero speed envelope:
Due to the different fluid movement within the outer swirl and swirl the way, and within the swirl swirling motion is from the outside gradually move into the process of the formation, then one must trace the axial velocity is equal to zero point. Cyclone normal separation process, fluid axial velocity is zero track called zero speed envelope. Zero speed envelope is the centerline of the recycle stream, is inner and outer swirl swirling boundaries. Structural parameters of certain cyclone, its shape and size zero speed envelope substantially unchanged.
The maximum tangential speed track surface:
To the two-phase flow into the cyclone body, outside the cyclone to form a spiral vortex swirling inward migration of the process, the tangential velocity of fluid particles have a maximum value, the maximum tangential speed. During normal operation, the cyclone flow trajectory maximum tangential velocity Physique point called maximum tangential speed track surface.
Air column:
To the two-phase flow into the cyclone body to spiral vortex movement, with gradually decreasing radius of rotation, the tangential particle velocity increases, when it reaches a certain value will form a negative pressure lower than the external space nips. Fluid entering the negative zone will precipitate from the air, while the air outside space will also be through the discharge port (Spigot and overflow) forming an air column into the negative zone. Internally and externally, cyclone product also catechism to face!

The Meaning of Dewaterin Screen Applications on Dry Tailings Discharge
Dry tailings discharge process has been successfully used in dry tailings discharge system, 85% -200 mesh for all slime cyanidation tailings dewatering, the product may be less than 18% moisture content. It has been developed for iron ore dewatering system.
Use of resources developed to produce the two products, high-grade enrichment of useful and useless waste product or material to be of secondary exploitation, in addition to black mineral of iron, manganese and fluorite, quartz and some other minerals, the majority of minerals after the use of tailings are generated a lot of the need for stacking and filling. Since some conditions and safety requirements, the original paddle tailings pile plan large investment, high risk, long construction period. Effective capacity utilization rate is low, more important is the lack of water resources in the region, some resources can not be exploited. After dry tailings discharge tailings dewatering system processes up to 75 percent return rate.
Multi-frequency vibration dewaterin screen dry tailings discharge process, the following range of applications, have better efficiency:
1, after the tailings brick, produce aerated bricks, small bricks;
2, with the original paddle row of ore to extend the life of tailings, tailings insufficient dry beach, do not meet the safety requirements but can not find a suitable place or prolong the service life of the tailings (to increase capacity of 1 / 4 ~ 1/3 or more);
3, after the library closed tailings, re-use can be dry stacked row, increase the capacity of 20-30%;
4, the original paddle discharge tailings, can be dry-discharge dam, safe and reliable.
5, the use of dry slag, filled pit, farmland;
6, built mine tailings area Location severe leakage of water environment.

Proper Operation of Hydrocyclone
Yantai Jinyang hydrocyclone is going to share with you the correct mode of operation of the cyclone, as follows:
1. Before you start commissioning to ensure that all connection points cyclone unit are tightened, remove the pipe, the housing units in a variety of residues, in order to avoid driving after a leak and clogging. Make sure to put into operation the cyclone valve is fully open.
2. The valve can be fully open (such as running a cyclone) or fully closed (such as alternate cyclone), but never allowed in a semi-open state (that never allows the valve to control the flow).
3. If possible, please test with water. Cyclone feed can be pumped or high slot provided. If the pump and cyclone throughput match, the gauge shows a constant reading. To ensure that the pressure gauge reading does not fluctuate, if you need to check the cause significant fluctuations. Equipment requirements to work in not more than 0.3MPa pressure.
4. Equipment running smoothly at normal pressure, the amount you want to check the connection point of leakage, take remedial action when necessary.
5. The residue was checked into the cyclone caused by clogging. Cyclone inlet flow blockage will reduce overflow and grit, grit cyclone grit mouth clogged traffic reduced or even stop, sometimes violently shaking. Such as clogging, should be promptly closed cyclone feed valve, remove the blockage. To prevent clogging, in hydrocyclone group pool feed can be added to prevent the precipitation of coarse material and debris of facilities (such as in addition to chip sieve), while parking in a timely manner when the feed tank empty, so as not to drive again, concentration is too high and cause clogging accident.
6. When the equipment has been running well water test confirmed, you can enter the slurry operation.
