Do I need a permit to install a dust collector?

Check with your local code enforcement agency, but in most cases you do need a permit. You can get fined for installing the dust collector without getting prior authorization.

What is the efficiency of a dust collector?

A properly sized dust collector is 99.9% efficient by weight (of inlet loading) down to one micron. This means if the dust collector loading is 100 pounds per hour, the bags will capture 99.9 pounds of the dust that is over one micron. This is a minimum efficiency figure. Pleated elements and special fabrics can improve efficiency.

Why do I need a dust collector on top of my silo?

Approximately 50 pounds (or more) of dust are exhausted into the atmosphere. A properly sized dust collector will capture this dust and return it to the silo.

When would I use a pulse jet collector?

The pulse jet collector was designed for continuous-duty applications where shutdown for cleaning is impractical. The pulse jet collector uses compressed air to clean the bags and the bags can be cleaned while on line.

When would I use the NOVA high temperature dust collector?

The NOVA is used when the design temperature exceeds 550º F. The maximum operating temperature of the NOVA is 1650º F.

How do I size the dust collector for my silo pneumatic filling operation?

When designing a dust collector for a silo, the following information is required: fill line size; quantity of lines filling at one time; air flow and pressure; loading time and material handled. Most applications use a single 4" or 5" diameter fill line running at 350 cfm @ 12-15 PSI for approximately 45 minutes. The material handled is either cement, flyash, or sand. A mechanical shaker dust collector with 250 sq.ft. of cloth area will be adequate for these applications.

OSHA's Proposed Silica Rule

Last year, OSHA proposed to toughen the rules against Crystalline Silica dusts in the workplace. According to OSHA's, crystalline silica exposure puts workers at greater risk for several deseases, including silicosis, chronic obstructive pulmonary disease and kidney disease. The proposed ruling would require businesses to implement tougher measurements against respirable silica dust in the workplace.

The ruling will have an large impact on many companies, including those in both the construction and metalcasting industries. At Griffin, we are keeping a close eye on this proposed rule's progress to ensure our customers will be ready if it passes.

Let us know if you have any questions about your current dust collection systems and how the rule will affect your operation.
