Capturing Excess Dust from Tablet Compression Machines

Losing excess dust from a tablet press during processing can be a major problem. Usually this excess powder is piped down the LEV line, to the central dust extraction system. This powder will come into contact with various filters during this journey, often causing them to blind. Changing these filters can prove both expensive and time consuming.


The Uni-Dust cyclone is designed to overcome this problem. By placing the cyclone between the tablet press and the LEV line, excess powder can be collected in capture-pot at the foot of the cyclone; this allows batch losses to be reconciled inside the process room itself. Importantly, the Uni-Dust cyclone normally separates over 95%the solids from the air, allowing clean air to pass to the central dust extraction system.

High Efficiency Cyclones for the Pharmaceutical Industry

The Hanningfield ‘Uni-Dust’ high efficiency cyclone is capable of capturing up to 99.99% of excess dust from pharmaceutical processing.

The high efficiency cyclone is uniquely placed within the process room itself, capturing excess dust in a catch pot.  This prevents excess powder from flowing to the central dust extraction, preventing the blocking of filters, and the expenses that come with changing these filters.

For example. Excess powder from a tablet press or a capsule filling machine can be collected in the process room itself - making batch loss reconciliation simple.

Pharmaceutical Dust Control

Dust control has become extemely important in the pharmaceutical industry.  As increasingly potent API’s are used in manufacturing, the risks associated can pose a serious problem.  One major concern is the operator hazard at being exposed to harmful substances which can be dangerous to health.  Another major concern is the safety of the process room itself, as the build up of powder can result in potentially fatal circumstances, as evidenced by the West Pharmaceutical Services dust explosion tragedy which took the lives of 6 people in North Carolina, 2003.

The Hanningfield ‘Uni-Dust’ Cyclone captures excess processing dust in the process room, to ensure powder does not escape to become a hazard to workers or the environment.  The cyclone also prevents a dangerous mix of powders from forming at the central dust extraction system, which again can be highly hazardous.  This again highlights the importance of pharmaceutical dust control.

Dust Containment - Make Your Process Safe

The containment of dust during pharmaceutical, food and chemical processing is vital.

Any excess dust which is not properly captured can enter the working environment and compromise the safety of workers.  Airborne dust particles can be extremely hazarous, hence the containment of this becomes vital.  The Uni-Dust cyclone helps contain this problem, whilst making product reintroduction or batch loss reconciliation possible.

Dust Control in Pharmaceuticals

The control of excess dust in pharmaceutical processing is extremely important.  Wayward dust can become airborne and compromise the safety of the working environment and the validity of other products.

Controlling the excess dust becomes vital, and the Uni-Dust powder recovery cyclone can play a pivotal role in this.  By capturing excess dust before it reaches the central dust extraction system, the filterless cyclone is able to retain waste powder in the process room.  This prevents a dangerous mix of powders from forming in the central filter, making the working environment much safer.  This also helps significantly prolong the life of the filter, which is often difficult and expensive to replace.

Innovative Powder Cyclone

The Uni-Dust powder recovery cyclone is capable of collecting excess dust from process machinery such as tablet presses or capsule filling machines.

This offers excellent advantages, as captured powder can either be reconciled or even re-used.

Product Profile

Leading the way in the control of excess dust from powder filling machines, the pioneering technology behind the Hanningfield filterless Uni-Dust powder recovery cyclone offers the ultimate in powder containment solutions.

Traditionally, waste material from powder filling equipment such as tablet presses and capsule filling machines is piped away to a central dust collector located in a plant room. This process results in a cocktail of various powders being stored in an uncontrolled area causing potential environmental damage and operator exposure.

New Hanningfield ‘All-Products’ Brochure

Our new ‘All-Products’ brochure is due to be posted to all our customers before the Christmas Break.  It highlights many of our most successful designs, such as the Uni-Dust Powder Recovery Cyclone, which was originally trialled successfully at a major pharmaceutical company in the south east of England.  With well over 30 units installed in the UK in the last three years, interest has now widened to Europe and the USA, for applications involving a diverse range of pharmaceutical powders and even titanium oxide.   

If you wish to receive a copy of this or any other brochure please complete the contact form and we will post to you immediately.
