Tower press filters are an essential equipment for solid-liquid separation. Some customers may have encountered an issue with the filter cake containing high moisture content and not drying. To address or prevent it, it is crucial to consider the following factors.
Filter Cloth Factors:
1. Filter cloth clogging
When using filter cloth, the accumulation and residue of material particles can easily block the aperture. This can seriously restrict the passage of moisture, which can prevent filter cake from being thoroughly dried.
2. Filter cloth quality
The surface of poor-quality filter cloth is not smooth, which leads to adhesion issues, residue sticking to the surface, making it difficult to release, resulting in liquid leakage and an increased moisture content in the cake. Additionally, the poor quality filter cloth may deform, affecting its effectiveness in filtration processes.
3. Inappropriate filter cloth
If we do not select the appropriate filter cloth according to the filtration equipment, working conditions, it will also lead to substandard filtration and an elevated moisture content of the filter cake.
Equipment Factors:
1. Insufficient pressure
The filtering power is derived from the pressure applied by the equipment. If the pressure setting is not adequately adjusted, the filtering power will be compromised, leading to a reduction in the dewatering rate of the filter cake.
2. Improper maintenance of equipment
To ensure optimal performance and prevent equipment malfunction, vertical filter presses require regular maintenance and care during use. Improper maintenance can lead to performance issues, such as filter cake not drying issue.
Filtration Material Factors:
1. High Material Viscosity
The material's high viscosity makes it easy to adhere to the filter cloth's surface. This increases the difficulty of filtration and can quickly clog the filter cloth and discharge channel.
2. Uneven particle size
The uneven size of material particles has a significant impact on the selection of filter cloth, which can easily lead to clogging of the filter cloth and uneven filter cake.
In summary, the issue of the filter cake not drying must be addressed and resolved in a comprehensive manner, considering the three aspects of filter cloth, equipment, and materials. For additional information, please visit the official BOLIAN website or contact us for consultation.
