Centrifuges

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.

Pharma Centrifuge offered comprise energy efficient machines that meet the demands of separating solids from liquids. These filtration type centrifuge finish featuring use of rotating basket for supporting of the filter media and delivers superior centrifugal force that forces liquid out through filter media with solid retained inside rotating basket. These also deliver higher centrifugal force that provides for optimum dryness of solids.

Product Details:

We are actively engaged in manufacturing and supplying a superior quality assortment of Four Point Suspension Centrifuge Machines. In a 4 Point centrifuge the vibration are isolated with a help of heavy Inertia Plate and Visco Dampers instead of a 3 point pendulum suspension where the vibration of centrifuge are isolated with a help of spring and Pendulum Bolts arrangement. Four point suspension centrifuges are manufactured using high grade factor inputs and advanced technology in compliance with international quality standards. In order to ensure their optimum quality, these are quality tested on various parameters by our quality inspectors. Also, these products can be customized according to the client's specifications and requirements.

Features :

• The vibration transmission is nil& operates very smoothly.
• Good and clean house - keeping possible
• Can be mounted on upper floor and can be easily relocated
• No cost of R.C.C foundation
• Can be shifted easily
• Working area is free from abstracts and a clean area can be maintained.

Specifications:

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.
