This equipment can be manufactured in various materials suitable for most process and corrosion requirements.
Material of construction include 'exotic' materials such as duplex stainless alloys, hastelloy, nickel, titanium etc. together with non-metallic inert coatings such as halar and PTFE.
Our range of Vertical Axis Basket Centrifuges is versatile and well-suited to the separation of pharmaceuticals and fine or bulk chemicals. As with all Broadbent designs of chemical centrifuges, the range is available in a wide variety of materials of construction. Nitrogen purging and designs suitable for use in Zone I hazardous areas are available.
Designed to handle a wide spectrum of materials, including Pharmaceuticals this range of machines offers process cleanliness without operator intervention. The design ensures a crevice-free polished internal finish with no dead areas. The peeler knife mechanism facilitates the complete removal of the product heel. Where necessary, a through-the-wall configuration completely isolates product and process from the actual machine operation and maintenance area. Peelers can be produced in a wide range of materials, and all incorporate advanced PLC control systems. Nitrogen purging is an option.

Thomas Broadbent & Sons Ltd have the world’s leading range of geotechnical centrifuges underpinned by Cambridge University’s Geotechnical Schofield Laboratory. These specialist geotechnical centrifuges are available with integrated data acquisition systems.
The new exciting range of geotechnical centrifuges designed and built by Broadbent, supported by Cambridge University’s Drum IPR, is sold under the ‘Broadbent G-Max’ name.
This range of geotechnical research tools brings together Broadbent’s centrifuge design skills, manufacturing expertise and internationally renowned service network. The data acquisition systems use G-Max's skills and geotechnical test know-how. We offer support from initial project concept through to final turnkey facility installation and training.
The product range of drum centrifuges, incorporates Broadbent’s Geotechnical ‘G’ Series Drum Centrifuges and the tilting drum centrifuge invented by Professor Andrew Schofield F.R.S, F.Eng., F.I.C.E of Cambridge University. This worldwide patent-protected drum technology (patent number US 5,634,876) is now integrated into the revolutionary Modular Centrifuge – the world’s first single-platform, multi-test environment, beam and drum centrifuge, designed specifically to offer the complete test environment to the civil engineering researcher.
The scroll-screen centrifuge consists of a horizontally driven scroll conveyor, which revolves at an optimum differential speed within a rotating conical basket. Solids separation from the mother liquor is achieved by the action of centrifugal force, operating at high g force, while discharge takes place via the inclination of the basket and the differential speed of the scroll. At the point of separation, solids are conveyed forwards by the scroll to discharge at the widest open-end of the filter basket, with the filtrate passing directly through the screen.
This type of centrifuge can be equipped with automatic scroll speed adjustment to accommodate changing process requirements, which completely eliminates operator intervention and process downtime. Scroll-Screen machines have an excellent washing capability and can be used for solids-liquid separation, where the feed materials have high particle sizes, i.e. 50 microns or above.
Originally designed for the reliable, robust and safe operation of centrifuges in hazardous areas, these Broadbent systems are designed for use in process plant operations where there is risk of explosion. Our systems maintain positive-flow purging and gas-blanketing with all necessary gas analysers, controls and alarms.
Each purging system carries out the following operations:
