Selecting the right dust collector

AAF Australia has recently supplied dust collectors to two sites, one belonging to a chemical company, the other an exotic alloy company. The company’s Tim McInerney spoke to ABHR’s Charles Macdonald about the jobs.

Selecting the appropriate dust collection technology for a particular industrial application can be a challenging task.

Many factors are at play. These include: the type of application; type of particulate, be it dry, wet, sticky or explosive; availability of services such as water and compressed air; hours of operation; and emissions regulations.

After that, suppliers and customers have to choose from a huge range of equipment, including: wet particulate scrubbers; reverse pulse jet bag type dust collectors; reverse pulse cartridge filters; reverse air dust collectors; and shaker type dust collectors.

AAF Australia recently supplied a Type W RotoClone to a chemical company in Victoria. According to Tim McInerney, the customer chose this machine after reviewing various other particulate scrubbers and after using the same type of machine previously for some years.

“For the new application, they decided to install a stainless steel model, compared to the mild steel of the older RotoClone,” said McInerney.

Options included larger clean out doors and extra flush out nozzles. The scope included complete unit, motor, and control panel.

“The water slurry draining from the unit is returned to the process and the particulate is water soluble so a RotoClone Type W wet scrubber was a good option for the customer,” explained McInerney.

“When compared to other types of wet scrubbers, our machine was also preferred because of its low capital cost, low water use, small footprint and low maintenance of the previous unit.”

In Western Australia, AAF recently supplied a stainless steel Type N Rotoclone Arrangement C to an exotic alloy company that manufactures wear plate parts for the mining industry. “We selected this type of scrubber over alternatives because of the low energy use, abrasive nature of the dust, potential for dust explosion, and high dust loading,” said McInerney. “On this application we provided an Arrangement C chain drive ejector so that the metallic dust was ejected out of the tank, with the collected dust easier to handle.

“The Type N Rotoclone has no requirement for pumps and uses little water. The supply included all items from inlet to outlet including mild steel fan and control panel.”
