dewatering screen machine manufacturer - gaofu
Because of environmental protection requirements and customers' needs to reduce costs, Gaofu has developed a dewatering screen. As a manufacturer with 38 years of experience in screening, Gaofu pays more attention to the improvement of customer quality and efficiency. This dewatering screen meets the market demand.
Compared with the traditional process, Gaofu companys new-type dry-line dewatering process has the advantages of low investment, simple process and small area which is convenient for the system process layout.
The dewatering screen features high wear-resistant screen plates with a long lifetime, modular assembly design, easy replacement, and low cost savings. Also screen mesh sizes can be selected according to requirements.
Dewatering screen is composed of mainly the screen box, exciter, support system and motor. Two counter-rotating vibration motors produce linear motion at an angle to the screen surface. The centrifugal force generated by the two eccentric masses is superposed along the vibration direction and reversely counteracted, thereby forming a single vibration force along the vibration direction and making the screen box reciprocating linear motion.
Dewatering screen, also known as high-frequency dewatering screen, changes the water surface tension of pulp through the exciting force. Thee washed sand is fed to the steep, downwardly inclined surface of the sand dewatering screen, so as to achieve rapid drainage. The dewatering screen is mainly used for dewatering tailings in the mineral processing industry, coal slurry dehydration of coal preparation plant, washed quartz sand dewatering and ceramic slurry dehydration, and wet and dry classification, dehydration, removal and mud removal of medium and fine granular materials in industrial sectors such as electric power, sugar making and salt making.
Dewatering screenadoptdual-electrode self-synchronization technology, universal eccentric block, adjustable amplitude vibrator. The machine is combined mainly by the screen box, exciter, support system and motor. The two mutually independent vibrators are respectively driven by the tape coupling to do synchronous reverse operation. The centrifugal force generated by two eccentric masses is superposedalong the vibration direction and reversely counteracted, thereby forming a single vibrationforcealong the vibration direction, making the screen box reciprocating linear motion.

screening machines & screeners
Super phosphate (SP), triple super phosphate (TSP) or double super phosphate (DSP) as well as diammonium phosphate (DAP) and monoammonium phosphate (MAP) are mainly used as fertilizers and are subject to strict quality requirements. Since phosphate fertilisers are produced in large quantities of several hundred tonnes per hour, even small efficiency deficits lead to high product losses. The aim of the screening process is to achieve high product purities at maximum throughput - and this can only be achieved by preventing clogging of the screen meshes.
The screening tasks in the processing of nitrogenous fertilizers such as ammonium sulphate (AS), ammonium nitrate (AN), calcium nitrate (CN), potassium nitrate (KN), calcium ammonium nitrate (KAS) and urea range from lump separation to the demanding separation of product fractions as well as dust removal. Screening nitrogen fertilizer with high efficiency and throughput requires precise adjustment of all machine parts as well as a well-functioning self-cleaning system, since urea and co. tend to bind air humidity in the dust fraction and thus clog the screen cloth.
To properly separate sugar requires the application of a high frequency directly to the material. The reason is, that sugar can become sticky even at low humidity levels and also tends to clog the sieve mesh, due to its crystalline grain shape. Screening machines with direct excitation of the screen mesh have therefore proven to be not only energy efficient, but also extremely precise. Thanks to the high accelerations, they reliably separate even finest sugars into several fractions simultaneously.
Efficient separation of metal powdersHigh-alloyed metal powders for 3D printing (additive manufacturing/ rapid technology) should be extremely pure to guarantee a high-quality end product. Dust and agglomerates must therefore be reliably removed from the extremely fine powder during production and recycling. A suitable screening machine should not only be highly precise, but also reduce the loss of valuable product and machine downtime to a minimum.
When processing dry mortar into different fractions, the fluctuating grain size distribution of the crushed limestone, as well as its tendency to clog up the screen mesh, lead to great challenges during screening. Efficient and flexible screening equipment can prevent these negative effects. On the one hand, it must be possible to individually adjust the oscillation amplitudes on each screen deck, and on the other hand, an automatic cleaning system is required to keep the screen surface open and thereby ensure throughput and product quality.
In this particular type of drive, two unbalance motors with different speeds are used. Upstream, a large oscillation amplitude ensures the loosening and removal of the material, while downstream, a small oscillation amplitude at higher acceleration ensures that even difficult to screen products are classified accurately.
Linear and circular vibrating screens are a cost-effective alternative to directly excited screening machines. They can be supplied with several screen decks on request and are available in tailor-made special designs. Their low-maintenance unbalance motors and good accessibility through large inspection openings simplify maintenance tasks.
By overcoming cohesion forces, our high-performance dewatering screens achieve maximum dewatering of solid particles from suspensions with optimized residual moisture content for particles down to less than 1 mm. In wet processing, the precise screening technology ensures efficient disagglomeration of the material and thus optimum separation of coarse and fine material.

mev screener - midwestern industries, inc
The high-frequency screens manufactured by Midwestern can be utilized in many screening applications from rugged quarry and rock sizing to sand and gravel processing and high volume fine mesh screening. With a variety of sizes and screening decks, the versatile MEV Screener can fit numerous applications.
The MEV High-Frequency Screener is a rectangular screener that utilizes an elliptical motion to convey material across itsscreening surface. Available in sizes three-foot by five-foot (3 x 5), four-foot by eight-foot (4 x 8), and five-foot by ten-foot (5 x 10) with the availability of one to five screening decks gives the MEV Screener the versatility to meet your screening needs.
The MEV Screener is designed to retain material at the feed end for a longer period of time and then gently slops the material near the discharge end, assisting itoff the screening deck and into production. This is achieved by the screeners unique parallel-arc configuration. Crossbars support the end-tensioned screens tocreate a flat screening surface, thus maximizing the screening area.
The end-tensioned screens used in the high-frequency screener simplify changing screen panels. End-tensioning permits the use of square-opening and slotted screens and is accurately maintained by a spring-loaded drawbar. Users can make screen changes in 1015 minutes.
Midwesterns commitment to providing our customers with outstanding screening products continues with our full line of replacement rectangular screens. Our screens are manufactured to fit all makes and models of screeners.
