Dust collection systems pick up dust generated by process equipment and move it away for disposal or to be recycled. They use hoods to gather the air around the dust generation equipment. The dusty air is then sent to the dust collection equipment through ductwork. The dust collection equipment often consists of a pre-filter to help collect the dust followed by the main dust collector. An exhaust fan is often at the end and it powers the system by pulling the air through each of these components.

Smaller cyclones avoid many of the disadvantageous and time-intensive aspects of larger cyclones, including those relating to installation and regulatory compliance. Here are the five frequently asked questions about using small dust-collection cyclones.

A manufacturer of grinding wheels in Niagara Falls, N.Y., needed to replace an existing dust collector used to collect dust coming off a rotary kiln. Initially, a bag house collector was considered to be the obvious solution. However, because the problem involved high temperatures – 700° F and above – specific efficiency requirements, moisture content problems, and future maintenance issues, the purchase of an Aerodyne SplitStream grinding dust collector was justified.

We all know that if we don’t regularly maintain our cars, we will end up having issues in the future. If we forget to change the oil, change the brakes or get a tune up, it will eventually catch up to us. Why do we think our dust collection system is any different? Dust collectors are made of various pieces, all of which have to be operating correctly for the system to operate as desired. Usually, a dust collection system consists of the dust collector, exhaust fan, ductwork, and hoods/pickup points. Additional accessories such as airlocks, controls, instrumentation, and dampers all can affect the operation of the system.

Dust collection is often one step in a series of steps used to treat an airstream or process stream. Often times the airstream will require heating or cooling, gas scrubbing, and/or dilution of gas stream, etc. All of these processes usually require additional equipment to work in tandem with the basic dust collector. Adding additional equipment is not only expensive, but it consumes floor space and often purchasing new equipment will get overlooked simply due to lack of space to accommodate it.

Most industrial dust collection systems use a baghouse or a cartridge collector. Whether your baghouse or cartridge collector is 50 CFM or 100,000 CFM, there are advantages to putting a cyclone before the baghouse or cartridge collector. Here are 5 advantages to utilizing a cyclone in a dust collection system.

The main reason to use wet scrubbing for particulate removal is that you need wet scrubbing for chemical or fume removal. Wet scrubbers such as a packed tower are great for removing chemicals (contaminant) in the air, such as acids, bases, etc.

When we think about dust particles being picked up by dust collectors we think of the particles as small spheres. And often for theoretical removal efficiency of a dust collector the dust is assumed to be a sphere. This is done to simplify the calculations as spheres act predictably compared to other shapes. However in real life dust isn’t normally spherical in shape. Dust is often created by material rubbing against each other and breaking off. This material often breaks along weak points in the material structure, which often isn’t spherical in shape. The material can have a wide range of shapes.

One common mistake operators make in dust collectors is to use the dust collector hopper to store material. The hopper in a dust collector isn’t designed for this. Instead it is a temporary home for the dust collected while the material is being removed. This period should be as short as possible for the following reasons:
