Improving the efficiency of the dewatering screen is the focus of many users, because it directly affects production efficiency, cost control and product quality. To achieve the best performance of the dewatering screen, RUIJIE suggests that you can start from many aspects, including equipment parameter adjustment, screen selection, material delivery optimization, etc.
The following are the specific measures of RUIJIE to improve the efficiency of the dewatering screen:
Adjust The Device Parameters
1.Vibration Frequency And Amplitude
- Vibration Frequency: Proper vibration frequency is a key factor in improving the efficiency of the dewatering screen. The higher vibration frequency can speed up the dewatering process of the material and help the fine particulate material to be dewatered quickly. Too low frequency will lead to too much residual moisture in the material and reduce efficiency; Too high may cause the equipment to wear out too quickly.
- RUIJIE Manufacturer Suggestion: Adjust the vibration frequency according to the characteristics of the material (such as particle size and moisture content), and it is generally recommended to keep it in the range of 900 to 1200 times/min.
- Amplitude Adjustment: The magnitude of the amplitude determines the movement trajectory of the material on the screen, and the appropriate amplitude helps the uniform distribution and dehydration of the material. If the amplitude is too large, it may cause the material to jump too fast and the screening is not sufficient; If the amplitude is too small, the material flow is not smooth and the dehydration is not sufficient.
- RUIJIE Manufacturer Suggestion: For materials with large particle size and high water content, use a larger amplitude; For fine-grained materials, the smaller amplitude helps to maintain a stable screening result.
Select The appropriate Screen Type
1.Screen Material
- Polyurethane Screen: Polyurethane screen has excellent wear resistance and elasticity, and is suitable for handling high-wear and fine-grained materials. Its durability and high dewatering efficiency make it the material of choice for many dewatering screens.
- Stainless Steel Screen: Stainless steel screen is suitable for high humidity and corrosive materials, with good corrosion resistance and long service life.
- Woven Screen: suitable for materials with larger particles, usually lower cost, but less durable.
2.Screen Size Selection
The pore size of the screen directly affects the screening and dewatering effect. If the pore size is too large, the fine-particulate material may not be adequately dehydrated; If the aperture is too small, it is easy to be clogged and affect the treatment efficiency.
- RUIJIE Suggests: choose the appropriate pore size according to the particle size of the material. It is recommended to choose a smaller pore size (e.g. 1-2mm) for fine particulate materials, and a larger pore size (e.g. 3-5mm) can be used for large particulate materials. In practice, it is possible to find the best screening efficiency and dewatering effect by testing different combinations of screen pore sizes.
Optimize Material Delivery
1.Uniform Material Delivery
Homogeneous material delivery is the basis for efficient operation of the dewatering screen. If the material is not evenly distributed, it will cause some areas of the screen to be overloaded and other areas to be fully utilized, thus reducing the screening and dewatering efficiency.
RUIJIE Supplier Suggests: To ensure that the material is evenly distributed on the screen, you can use the automatic feeding equipment or adjust the angle of the feeding equipment to make the material evenly enter the dewatering screen.
2.Control The Moisture Content Of The Material
The initial moisture content of the material has a direct impact on the efficiency of the dewatering screen. Materials with too much moisture content can make dewatering more difficult, leading to screen clogging and reduced processing speeds.
RUIJIE Suggests: Before the material enters the dewatering screen, try to reduce the moisture content of the material. For example, pretreatment processes (e.g. gravity drainage, centrifuge treatment, etc.) can be used to reduce excess water in the material in advance.
3.Control The Flow Of Material
If the flow rate of the material is too large, it may lead to the overload of the screen and affect the dewatering efficiency; If the flow is too small, it will reduce the overall processing power of the device.
RUIJIE Suggests: according to the processing capacity of the dewatering screen, reasonably control the amount of materials to avoid overload or underloading. By monitoring the feed and discharge speeds, the material flow can be dynamically adjusted.
Regular Maintenance And Maintenance
1.Screen Cleaning And Inspection
A clogged screen can seriously affect the screening and dewatering results, so it is important to keep the screen clean.
RUIJIE Recommends: Clean the surface of the screen regularly, especially when dealing with materials containing sticky materials or materials with high moisture content, to avoid clogging and wear. In addition, check whether the screen is worn or damaged, and replace the screen in time if necessary to ensure the dewatering efficiency.
2.Vibrating Motor Maintenance
The vibrating motor is the core component of the dewatering screen, and its performance directly affects the operating efficiency of the equipment.
RUIJIE Suggests: Regularly fill the bearings of the vibrating motor with lubricating oil to keep the motor in a lubricated state and avoid motor failure caused by wear. Check whether the eccentric block of the motor is loose at regular intervals and tighten if necessary.
3.Check The Shock Absorber Regularly
Shock absorbers, such as rubber cushions and springs, are essential for maintaining the stability of your equipment. If the damping device fails, the vibration effect of the equipment may deteriorate, which in turn will affect the dewatering efficiency.
RUIJIE Suggests: Regularly check the condition of the shock absorber device, and replace it in time if it is found to be worn or aged.
Add Automation Control
Through the automatic control system (such as PLC controller), the equipment operation status can be monitored in real time, the parameter setting can be optimized, and the material flow, vibration frequency and other parameters can be automatically adjusted to ensure that the equipment is always in the best working condition.
RUIJIE Suggests: equip the dewatering screen with an automatic control system, so that it can be linked with other production line equipment (such as conveyor belts, sand washing machines, etc.), optimize the overall production process, and reduce manual intervention.
Improving the efficiency of the dewatering screen can be achieved by adjusting the vibration frequency and amplitude, selecting the appropriate screen type, optimizing material delivery, regularly maintaining the equipment, and adopting an automated control system
Through scientific and reasonable adjustment and maintenance, users can significantly improve the efficiency of the dewatering screen, reduce costs and improve the quality of output.
