GN High Shear Circular Screen for Overseas Silicon Sand Classification Project

Several days ago, GN Separation has successfully assembled and undergone factory testing for a high shear circular vibrating screen, model no. GNYK1028, which is scheduled to be shipped abroad for a silica sand classification project.

GN High Shear Circular Vibrating Screen GNYK1028

GN High Shear Circular Vibration Screen is a groundbreaking equipment, developed solely by GN Separation Technical Team. This innovative screening equipment is designed to harness the power of a single vibration source, a vibration motor, to generate circular motion in the screen deck assembly. Its working principle is to sieve the materials on the screen driven by the vibrator. The technology design makes it of excellent performance on processing a range of materials, including but not limited to the following categories:

Chemical products: such as pigments, coatings, paints, resins, titanium dioxide powder, rubber particles, etc.
Food: such as flour, sugar, salt, grains, etc.
Medicine: such as Chinese herbal medicine, western medicine, bulk drugs, etc.
Ceramics and mining: such as ores, like iron ore, gold ore, silica sand, feldspar, coal, etc.

My pleasure to introduce its outstanding features as below:

  1. Robust Operation: The screen relies on high-performance vibration motor brands like Martin motor or OLI motor, ensuring it with both dependable operation and long trouble-free operation time.
  2. Efficient Processing: The screen deck is meticulously designed with multiple sections, significantly boosting its treatment capacity. This configuration offers higher working efficiency, lower energy consumption, consistent performance, and reduced customers’ maintenance needs in actual applications.
  3. Enhanced Screening Effect: Each section of the mesh is equipped with a re-pulp spray pipeline, which further improving the screening process efficiency.
  4. Durable Construction: Heat treatment technical carried out on the whole screen deck ensure it to withstand the high-intensity vibration during long-term using. Via surface heat treatment, the screen mesh surface structure is changed to more compact and stronger, improving hardness and corrosion resistance, thereby enhancing its wear resistance and durability. Meanwhile, form a protective film cover, which can effectively prevent the screen mesh from being oxidized and corroded to enhance the corrosion resistance of the screen mesh and extend its service life. What’smore reduce the roughness of the screen mesh surface, making it smoother, effectively improve the working performance of the screen mesh and increase its screening efficiency and accuracy.
  5. Quiet Operation: The use of flexible polyurethane screen mesh, ensures minimal equipment noise in operation. It is a kind of high molecular polyurethane elastomer, with excellent physical and mechanical properties: high strength, large elasticity and rather nice wear resistance, with an opening rate of polyurethane screen mesh is 28% ~ 45%. GN is committed to providing customers with flexible polyurethane screen mesh with finer mesh, higher opening area and better polyurethane screen surface.
  6. Easy Maintenance: The screen mesh is secured using bolt components that are easy to disassemble for inspection and reassembly, ensuring convenient and reliable fastening.
  7. Longevity: The vibrating screen components’ fluids touching surfaces are coated with a polyurethane resin wear-resistant and anti-corrosion layer or protected by wear-resistant rubber plates by the spraying machine imported from the United States, which is corrosion-resistant, erosion resistant and wear-resistant. Which extends the durability of the screen equipment.

As a high-frequency vibrating screen, GN High Shear Circular Vibration Screen operates at a frequency of 25Hz, ensuring efficient separation of materials even at smaller sizes. It can be applied in various working conditions that are easy to corrode and wear. Large processing capacity, high efficiency and stable performance. GN manufactures proffessional Mining Vibrating Screen, including Stack Vibrating Screen, High Frequency Vibrating Screen, Dewatering Vibrating Screen, Classification Vibrating Screen, Large Mining Vibrating Screen.

Requirements of lubricating oil for decanter centrifuge

During the daily operation some wear will occur to the Decanter centrifuge. So maintenance is imperative in order to extend the service life of the equipment. Lubricating oil must be used regularly. Below we introduce the precautions for adding lubricating oil to the Decanter centrifuge.

The Decanter centrifuge has two main components that need to be lubricated. One is the bearing and the other is the reducer. The bearing is greased, commonly known as butter; the reducer is lubricated, that is, gear oil. Butter is grease. One of the main quality indicators for evaluating grease is the freezing point. Freezing point is the maximum temperature when the oil is not flowing under the specified conditions. The freezing point of butter is higher than normal temperature. When the heating temperature exceeds the freezing point, it can melt and flow. The melted butter can lubricate the bearings, reduce the friction between the components, reduce wear, and have the effect of cooling.

Gear oil should have good abrasion resistance, load resistance and suitable viscosity. In addition, it should have good thermal oxidation stability, anti-foam resistance, water separation performance and anti-rust performance. Gear oil is a lubricating oil with excellent performance. Gear oil is a kind of important lubricating oil mainly composed of petroleum lubricating base oil or synthetic lubricating oil, which is added with extreme pressure anti-wear agent and oily agent.

  1. The lubricating oil should have a certain stability. In the working environment of some decanter centrifuges, the temperature difference between day and night is large. If the oil is poor, it will cause the formation of a lubricating film, which will not play a lubricating role. In order to prevent the occurrence of fire, lubrication should also have flame resistance.
  2. The selected lubricating oil should have certain thermal stability and oxidation resistance. Because the oil tank of the decanter centrifuge is small, the amount of lubricating oil is necessarily small. Moreover, the long-term operation of the decanter centrifuge will increase the temperature of the bearings and other parts, so the lubricating oil needs to be thermally stable.
  3. The working environment of the decanter centrifuge will be contaminated by dust, moisture and other impurities. Therefore, there are requirements for lubrication such as anti-rust and anti-corrosion functions. When impurities are contaminated in the lubricating oil, its performance will not be greatly affected. It does not affect the normal operation of the equipment as standard. Butter is usually added once a shift, gear oil is added at least once a week, and needs to be replaced once a month. So as to meet the maintenance needs of decanter centrifuge.
