Centrifuge Bags

Centrifuge bags  are utilized extensively by pharmaceuticals, chemicals and drugs manufacturers. As centrifuges are typically used in acidic environment, polypropylene is widely used for top lifting, top discharge and bottom discharge centrifuge bags.

Centrifugal energy is used in such a way that the wall of the centrifuge is the media and permits the filtrate to go through while leaving the solids on the surface. These solids can be put to wash and then detached continuously by an unloading knife and discharged out from the particular means.

Technical Textiles India a leading supplier of centrifuge filter bags to customers in pharmaceuticals, chemical processing, fertilizers, food processing, etc. Our centrifuge bags are custom-stitched to your specifications and provide you and optimal balance between production and quality.

A complete solution

To provide customized filter bags, we begin with an assessment of the process to understand particle retention and  flow rate requirements to suggest the right fabric to be used in terms of the weave and yarn (spun/ mono or multi-filament yarns)

Coolant Filter Papers

What are Coolant filter Papers?

Coolant Filter Papers are typically used in the machine tool process to separate metal debris and dust from the coolant, enabling the coolant to be recycled and precious metal waste to be reutilized.

We supply continuous band filter papers of varying particle retention size to retain the particles from the contaminated filter media. The clean coolant filters out through the fabric leaving a “cake” of the metallic particles.

Rotary Vacuum Drum Filter Cloth

What are the Rotary Vacuum Drum Filters?

The rotary drum vacuum filters, a workhorse of the chemical process industry for many years, has been designed for long life and easy maintenance.   These filters involve half of the drum being submerged in the slurry and the other half above it. The Filter Cloth or belt winds around the drum, and as the drum rotates, the slurry is sucked into the cloth.  As the drum rotates, the cake is dried using vacuum pressure on the exposed area, and the cake is formed. The dried cake is discharged as the drum rotates.

Rotary Vacuum Drum Filter Cloth

Our range of Rotary Vacuum Drum Filter Cloths

• Our wide range of woven and non-woven media allows you to balance throughput, cake discharge, and long-life.

• High particle retention, bursting and tearing strength, and abrasion resistance of the fabric besides chemical and thermal compatibility are important. Besides, abrasion resistance is required as the process of removal of the dried cake involves scraping.

• Our quality Filter Cloth withstands the rigorous scraping process used to remove the dried cake.

• We often recommend a double-layered fabric to ensure the longevity of the filter cloth and better separation. Hence, we also offer a knitted nylon backing fabric that can be used underneath the top cloth to provide a cushion and stability for the cloth as it moves through the Rotary Drum process

• Innovative agitator rake design ensures solids remain in suspension and avoids
  sediment in the system tank for better materials distribution

• Wide range of choices for drum material to suit process demand– polypropylene, carbon steel (unlined or rubber-lined), stainless steel, as well as other materials

Vacuum Belt Filters

What are Vacuum Belt Filters?

The vacuum belt filter is used for the filtration of liquids and de-watering of sludge, which are rich in solids, quite often about 50-60% of the slurry. The vacuum belt filter utilize gravity along with additional vacuum support, by using fixed vacuum trays with a continuously moving belt on top of the same. The belt may move continuously or in steps in sync with the slurry feed. As a result, higher throughput and better de-watering of the filter cake can be achieved. Depending on the application, filter fleeces or endless filter belts are used. 

Cake washing is accomplished by nozzle sprays or drying by vacuum.

Sparkler Filter Pads

What are Sparkler Filters?

Sparkler Filter pads are concentric circles that are put together in a filter cartridge assembly.  The inside shell of the assembly comprises of the pre-arranged filter plates with perforated sustaining screens, sparkler filter pads, and inter-locks. The assembly is complete with pump and piping connection mounted on a stainless-steel trolley. The contaminated liquid to be filtered is fed to the filter shell by a pump. It flows through the top of each plate through the opening on the sides of the plates. As liquid pressure increases, the filter media (Paper/fabric) holds back the impurities & allows the crystal-clear filtrate to go by through the central channel (formed by interlocking cups) which takes the filtrate to the exit of filter.

Sparkler filter pads are typically used to get the clear fluid. Sometimes the cake formed between the plate is also obtained. Filtration is continuous until its rate reduces due to augmented cake resistance.
