Dynamic Cyclone Cleaning

1 billion tonnes of cement – that’s the estimated amount currently produced in the world per annum and with cement production involving the handling and processing of dry powder materials, it is not surprising that plant operatives are constantly on the lookout for solutions to their dry material build up problems.

We’ve talked before in our acoustic cleaning blog about  silo and id fan cleaning in cement plants and today we tackle another issue they have to deal with …. blockages in dynamic cyclones.

Dynamic cyclones can be prone to impeller blockage and damage. This in turn can cause cyclone blockages and prevent efficient up-stream equipment operation. With the installation of acoustic cleaners the airflow can be maintained correctly and solids separated by eliminating particulate build up.

Installation of our acoustic cleaners into a cyclone can produce huge savings over time and we have a wealth of experience in this particular application.

To demonstrate this, here are some of the initial key pieces of information we require to allow us to quote for cyclone cleaning:

•    Nature of material being collected
•    Temperature inside the cyclone
•    Percentage moisture content of the material
•    Cyclone size and material it’s constructed from
•    How fast the build-up occurs
•    Information about the inlet ductwork

Once we receive the completed questionnaire, we can then assess the optimum type, size and number of acoustic cleaners likely to be required and offer our best quotation for their installation.

Our acoustic cleaners are also an effective material build-up solution for dynamic cyclones in carbon black plant operations where there is the added challenge of maintaining air flow and efficiency in static cyclones and their associated ductwork .

Carbon Black Cleaning - More Acoustic Cleaners Please!

In a previous blog post we wrote about our involvement with carbon black silo cleaning and how we had supplied 2 units of our PAS-75 acoustic cleaner to assist with the operation of carbon black silos at an industrial rubber plant in Hungary.

It is only a few months since our acoustic cleaners were installed on site and we have already received a new order from the plant operators for a further 3 units of PAS-75. Orders speak louder than any words!

If you are involved in the production, storage or transportation of carbon black, please visit our carbon black page to learn about the wide range of applications to which our acoustic cleaners can be in order to minimize material build-up and improve plant efficiency.

We cover id fans to mechanical pre-collectors, dynamic cyclones to precipitators, ductwork and more. A must read!

Carbon Black Silo Cleaning Success

Carbon black is a commodity which is produced and processed on a large scale around the world. The properties of carbon black are such that it requires careful handling and storage. From a human perspective, engineering controls have to be used to limit the exposure of people to carbon black dust during site operations and from a site management angle, fine carbon black dust has to be prevented from penetrating electrical equipment as it can cause electrical shorts.

Storage of carbon black is equally important – it has to be stored in a dry place and well away from potential sources of ignition and strong oxidizers. Storage of carbon black is commonly carried out using silos. The fine dust can cause build-up and blockages which in turn can result in major plant shutdowns and loss of valuable bulk storage space. Effective cleaning and prevention of build-up in carbon black silos is therefore a prime objective within carbon black storage and production plants.

We recently sold two PAS-75 acoustic cleaners for this exact purpose - for two carbon black silos at an industrial rubber plant in Hungary. Here is a photograph of one of our acoustic cleaners mounted on top of one of the silos.

Below is a close-up photograph. Height of the silos 14.5m, diameter just over 3m.
