Rubber Filter Belt

Rubber filter belt is also called rubber drainage belt (vacuum belt), it is key part of vacuum belt filter(HVBF or VBF). The Carcass material of belt is PE/EE, which has excellent qualities like high strength, anti-acid/alkali/petrol/low and high temperature, and the most outstanding feature is low elongation rate under specified load, this can make sure the fabric is not easy to deform.

Rubber Filter Belt

Rubber filter belt is also called rubber drainage belt (vacuum belt), it is key part of vacuum belt filter(HVBF or VBF). The Carcass material of belt is PE/EE, which has excellent qualities like high strength, anti-acid/alkali/petrol/low and high temperature, and the most outstanding feature is low elongation rate under specified load, this can make sure the fabric is not easy to deform.

According to different working conditions, rubber cover material can use different formulas then to meet different needs. Belt shaping and vulcanization are done in a single operation without the need for an additional splicing step, significantly enhancing belt straightness performance stability.

Grooves are cutted or molded into top cover of rubber filter belt, and in the specific middle, there will be drainage holes. When working with vacuum pump, filtrate can go to vacuum box through these holes. The drainage hole part is fabric-free, so that corrosive liquid will not contact fabric to cause delamination, this will prolong the service of a rubber filter belt.
 
Super Wide Rubber Filter Belt
With the development of the vacuum belt filter industry, more and more filters need 4m and wider belts. Sunny has the largest vulcanizing machine in China, which can produce belt wide to 6m, meet the market requirement and help customers to save cost.

Product Application

Rubber belt is a key part of belt filter (rubber belt vacuum filter). The frame of rubber belt is made of high quality polyester canvas or polyester fabric. The rubber can be varied by changes in the proportions of ingredients, which uses one-time vulcanization process for forming, satisfying different working conditions.

Rubber filtration belt is most important part for vacuum belt filter, it is also called rubber filter belt, rubber filtration belt. The carcass material of the belt is EP/EE, which has excellent qualities like high tensile strength, anti acid/alkali/petrol, anti high/low temperature, and the most outstanding quality is minimal elongation under a specific load, greatly reducing the opportunities for deformation.
 
Rubber cover material can be specially formulated to meet specific needs of operation conditions. Belt shaping and vulcanization are done in a single operation without the need for an additional splicing step, significantly enhancing belt straightness performance stability.

To prevent slurry/filtrate overflow, curbs are attached on both edges of the belt, both ripple curb and flat curb are available according to customer requirements.
