application of dewatering screen in beneficiation process of potash feldspar

Recently, most of manufacturers choose spiral classifier and pressure filter to dehydrate potash feldspar during dehydration process. But there are some disadvantages, spiral classifier cannot classify materials completely and pressure filter needs large investment. Whats more, if users adopt spiral classifier to deal with the separation of residue water during the production of potash feldspar, it will cause the finished materials containing too much water so that the materials cannot be dry heaping. It is found that if users adopt dewatering screen instead of spiral classifier, the water content of potash feldspar will be less than 15% after dewatering by dewatering screen and the materials can achieve dry heaping effect. Furthermore, it can increase recovery rate of finished products because the dewatering screen can elect fine sand which will lose caused by spiral classifier. There are two applications for dewatering screen used in beneficiation process of potash feldspar, one is used for classification of potash feldspar which is processed by ball mill, another is used for dewatering of potash feldspar products. In the traditional production process, it always uses pressure filter to deal with this kind of materials during the dewatering process of potash feldspar products. But this kind of production technical has large energy consumption, lower working efficiency and higher water content. While if users adopt dewatering screen to deal with potash feldspar, it can improve the production efficiency greatly, also can reduce energy consumption and floor space.

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.

Dewatering screen, also known as high-frequency dewatering screen, changingthe water surface tension of pulpthrough the exciting force, pulp water through the screen to become the undersize material, and fine material is blocked by the screen to form the filter layer by the vibration of the forward movement of discharge.

screening machines for potash

screening machines for potash

When processing potash, screening machines are initially used during extraction, where the mineral extracted from the mines is crushed and pre-classified. In the further process, screening machines are required in compacting, granulate screening or loading. In addition, screening machines are found in wet classification and dewatering.

Due to their low energy requirements, screening machines are not only suitable for the pure production of saleable products, but can also relieve crushing plants and thus avoid cost-intensive overgrinding.

For separations from 2 to 25 mm (10 Me. to 1), as produced during prescreening, compacting or loading, robust and low-maintenance double-frequency (DF) screening machines are particularly suitable. Due to their special drive principle, they achieve enormous screening capacities with consistently high quality separations. The special drive concept involves the use of two unbalanced motors with different speeds, which are mounted at the inlet and outlet.

At the inlet area, the potash is loosened up and sorted ("segregation") by the larger amplitude, followed by smaller oscillation amplitudes at the outlet area, which increase the screening accuracy and thus effectively separate the oversized grains.

For finer separations below 2 mm (10 Me.) (e.g. of KCL crystallisate) the screening machine with direct excitation of the screen cloth RHEWUM WAU is recommended. It is suitable for exact separations at high throughput rates.

On the outside of the static screen housing, robust vibration motors generate vibrations which are transmitted directly into the screen mesh via vibration axes. The inclination of the fabric is used for transport. A thin layer screening is performed on the screen cloth at high screenings speed. Any stuck grain is reliably freed thanks to an adjustable cleaning cycle. Due to the low moving masses (only the mesh vibrates), high accelerations are achieved at the screening surface. These help to overcome adhesive forces in moist or sticky material (e.g. rolling granules).

The wet classification of potash alt requires schort screen lengths, as a rapid loss of the carrier liquid would inhibit further wet screening. Therefore, the RHEWUM RIUS 1+1 relies on double feeding within the same achine and makes high screening capacities possible in spite of its compact design.

After the enrichment of the potassium part, the during the wet screening process, the potash mash is dewatered, compacted and screened. For dewatering potash, we recommend the linear vibrating screen RHEWUM ES, which operates at a high frequency suitable for efficient removal of solid particles from suspensions.
