Centrifuges

Product Details:

In basket centrifuges, the solids & liquids are separated by centrifugal force using a filter media (usually a cloth) mounted over supporting mesh, which are together supported inside the rotating basket. The slurry to be filtered is fed through the feed nozzles to the basket and due to centrifugal force the liquid is forced out through the filter media while solids are retained within the filter media inside the basket. These solids then separated or discharged by various discharging methods namely - manually, bag lifting basket, through scrapper, operated manually pneumatically / hydraulically, for which different models are available.

Suspension / Mounting :
All the bottom driven basket centrifuges can be supplied either in 3 point type suspension or the newer 4 point type mounting (on VISCO Damper / Sordino Damper) anti vibration mounts.

Material of construction :
Carbon Steel, Stainless Steel, Hastalloy, Rubber Lined, Fluoro Polymer Coatings like Halar (ECTFE), PVDF (ETFE ), Teflon (PFA) etc. Lining / Coating can be provided on the contact parts as well as on the exterior body for prevention from spillage and corrosive atmosphere.

Advantages of 4 Point Mounting :
Level of vibration is much lower & operates very smoothly.
Can be mounted on upper floor and can be easily relocated.
Almost negligible maintenance cost.
Working area is free from abstracts and a clean area can be maintained.

Product Details:

The process of Filtration is similar to other types of centrifuges, the difference being in the method of unloading the Solids. The centrifuged solids are scrapped through a scrapper operated either manually, pneumatically or through hydraulic cylinder and the solids are discharged through openings provided in the Basket bottom and Bottom Base / Inertia Plate while the basket is rotating at a slow speed. The centrifuge is driven at 3 speeds i.e. the feed speed, centrifuging feed and scrapping speed (around 60 rpm) The drive motor is controlled by variable AC inverter drive to vary basket speed with built in dynamic braking system. The AC drive is incorporated with microcomputer and has a facility to interface with programmable logic controller(PLC) for complete automation.

TYPICAL BOTTOM DISCHARGE CYCLE:

• Feeding : A filter media is fixed to the cylindrical surface of a perforated basket. The feed slurry is directed to the basket wall using a feed pipe. Feeding is carried out while the basket is rotating at an appropriate speed. After the required cake is built, feeding is stopped. The centrifuge is run for some time to partially de-water the solids. Feeding can be repeated if there is adequate space for further build up of cake.
• Washing : After feeding, washing is carried out by pumping wash liquid through the wash pipe.
• Spinning : The basket is run at the spinning speed to complete the de-watering process.
• Scraping : The speed of the basket is reduced to the scraping speed (slow speed). A scraper knife cuts the solids, discharging them through the chute.
• Heel Removal - Optional : Some material remains on the filter media after scraping and is called residual heel. This heel can be removed by using the heel removal system.
• Cleaning In Place - Optional : The centrifuge can be cleaned using a CIP system.
• Dynamic Braking :The centrifuge basket is braked or slowed down using an electrical braking system. The back EMF generated by the motor when idling is used to create the breaking impulse. This braking ensures a safe and friction free means of halting the rotating assembly.
  Seperate heat sinks are given to ensure that the heat generated is dissipated effectively and the unit can be located even outdoors.

Advantages:

• Cake Discharge in powder form.
• Solid discharge in closed environment
• Operation can be automated using a PLC.
• Heel Removal System enables regenerating of filter media.
• Toxic, allergic or hazardous material can be safely handled.
• Minimum attrition of crystal due to scraping at low speeds.
• No contact between product and operator during operation.
• Drastic reduction in manual labour due to discharge of filter cake with help of a scraper.

Material of construction :

• Stainless Steel , Carbon Steel, Hastelloy, Rubber Lined , Fluoro Polymer Coating / Lining viz.- Halar (ECTFE), Teflon (PFA )
• Lining/ Coating can be provided not only on the contact parts but also on the exterior body for prevention from spillage and corrosive atmosphere.

Note : Bottom Discharge Centrifuge is advised for a non-sticky crystalline product which can be easily cut by the scraper blade.

Product Details:

Hydro Extractors are also called Centrifuges. Centrifuges are for water extraction (dewatering, pre-drying) of textile materials. Values of approx. 15% for residual moisture content can be achieved depending on the type of textile fiber. Centrifuges with perforated drums or baskets (Ø up to approx. 2000 mm) which oscillate vertically in ball-and-socket joints suspended on three points are produced in various designs as pendulating, suspension, cage and vertical centrifuges, also with so called gliding support bearings as gliding support centrifuges or in horizontal resp.

Vertical arrangements as open-width, horizontal and warp-beam centrifuges, etc. Most centrifuges have electric drives for speeds of approx. 750-1200 rpm and are generally provided with automatic control over various ranges.

For safety reasons, an interlocking lid is essential on a centrifuge so that the motor cannot be started until the lid is locked, nor the lid rose until the basket is stationary again after the machine has been stopped.

Product Details:

In a Bag Lifting type Centrifuge a chain pulley block and hoist is required to lift the bag out of the centrifuge and there are chances of product contamination in these devices, instead for a clean room application a specially designed hydraulic lifting device is used for lifting the basket top with filter bag along with solids after filtration.

This arrangement consists of a central pillar with hydraulic ram movement inside the pillar attached to the lifting arm. These ram aides the movement of arm up and down with hydraulic power pack controlled through a control panel. After filtration the basket top cover with filter bag and solids are hooked to the arm of the bag lift arrangement to lift the bag vertically upwards and to turn around through its pillar centre pivot point, mounted on bearings and the solids are unloaded. This system eliminates the usage of any chain pulley block.

The system is also available confirming to cGMP standards.
