The vacuum belt filter band is a mechanism that performs filtration in various applications and comes with several advantages. It is widely preferred in the industrial sector. So, what is a vacuum belt filter band, and what are its advantages and areas of application?
Vacuum Belt Filter
The vacuum belt filter is a commonly used filtration system in the industrial sector due to its easy operation principles and high tonnage capacity. Vacuum belt filters are generally preferred for materials with a crystalline structure and large-sized solid particles. The liquid within the material fed onto the belt is extracted through a vacuum chamber located beneath the belt, separating it from the solid components. The width of the belt can vary between 1000 millimeters to 3000 millimeters.
The vacuum belt filter is highly resistant to corrosive sludge and is frequently chosen for its fundamental working principle. It is a continuous horizontal filter that uses vacuum assistance to separate solid materials from suspensions. The vacuum belt filter is versatile and finds applications in the chemical, food, pharmaceutical, environmental technologies, and mining industries, as well as in the paint and pigment sectors.
Vacuum Belt Filter Band
Vacuum belt filters are preferred in the industry due to their easy operation principles, resistance to corrosive sludge, and high tonnage capacities. The equipment of the vacuum belt filter consists of a band that moves on a flat platform.
The sludge is fed onto the filter cloth from the end of the band, and the liquid part is drawn through the filter belt’s pores using a vacuum. Subsequently, the dry cake is separated from the filter cloth at the other end of the band. The vacuum belt filter is multi-functional and also ideal for cake washing applications.
The vacuum belt filter band is made of materials such as polyester, polyamide, polypropylene, or PEEK with high durability. It offers excellent chemical and mechanical resistance. To ensure performance in challenging conditions, the surface of the filter belt can be treated with special processes, thereby increasing filtration efficiency.
Advantages of Vacuum Belt Filter Band
The advantages of the vacuum belt filter band are as follows:
Superior temperature and chemical resistance
High filtration capacity
Dimensional stability
