5 Reasons Why You Need a Dust Control System

Within manufacturing processes, there are times when production equipment generates dust that can prove difficult to eliminate. Because of this, the manufacturing industry must apply dust control methods to these dust generating processes.
The top five reasons for implementing dust control methods into your processes

1. Improve the quality of the product ·Reduce or eliminate unwanted dust on the product

2. Reduce employee exposure ·Improve employee health by reducing the dust concentration in milligrams per cubic meter (mg/m3)

3. Reduce equipment process safety risks ·Dust build-up on equipment could become a fire hazard ·Dust build-up on surrounding equipment/building area increases a secondary explosion risk

4. General housekeeping

Troubleshooting Fan Speeds

Troubleshooting Fan Speeds
Let’s say you are out in the field doing some troubleshooting on an air system fan, or any other type of motor-driven sheave (pulley) system, and you need to determine fan revolutions per minute or RPMs.  

The easiest way is to measure the RPM with your tachometer.  You reach into your tool bag only to remember that you let a team member borrow it and they have not yet returned it.  Not to worry because you always have a backup-plan – math!
You can use the following formula to determine the fan RPM:
Find These Variables ·Record the motor RPM from the motor tag ·Measure the motor (driver) sheave diameter in inches ·Measure the fan (driven) sheave diameter in inches
Example Problem Motor RPM from the motor tag - 1750 RPM Motor (driver) sheave diameter – 10.0” Pitch Diameter (P.D.) Fan (driven) sheave diameter – 14.0” P.D

Estimating Electric Motor Operating Cost Per Year

Estimating Electric Motor Operating Cost Per Year
When determining the operating cost of a project, it is important to remember motor operating costs. To determine these costs by using the following formula: EMOC/YR = (HP) (%FL) (0.746 HP KW) ($/KWH) (HRS/YR)/MOTOR EFFICIENCY Where ·Estimated Motor Operating Cost per Year = EMOC/YR ·Motor Horsepower = HP ·Motor Percentage of Full Load = %FL ·Horsepower to KW factor = 0.746 ·Dollar per Kilowatt Hour = $/KWH ·Motor Operating Hours per Year = HRS/YR
Example For an example use the following variables to determine an estimated motor annual operating cost: ·

Why you don't need explosion protection on drum filters

Why you don't need explosion protection on drum filters

We at ATMOS360are in the business of engineering and manufacturing dust collection systems and equipment. As we develop the scope for new systems, as well as upgrades to existing systems, we must evaluate the options for the use of a baghouse filter versus a drum filter.

The Need for Explosion Protection One important factor is the need for explosion protection. The cost of an explosion protection system can add as much as $100,000 to the cost of filtration equipment. The need to provide explosion protection on a baghouse filter is typically straightforward and, in most cases, is needed. Drum filters, however, are a different animal and for some installations, explosion protection is not required. Typically drum filters have rounded floors and inlet ductwork designed to provide a low sweeping inlet. This keeps the floor clean and minimizes the amount of material within the dirty air plenum.

Drum Filter vs Baghouse: 5 elements to consider when determining the best system for your plant

When considering a drum filter or a baghouse, one should consider the following elements to determine what type of system is best for the plant.
Application In manufacturing, there are countless applications. When looking at the application of baghouses verses drum filters one of the primary elements to consider is the dust being processed.  Drum filters were initially developed for the textiles industry, which produces long fiber dust.  Therefore, if your process generates dust with long fibers then a drum filter may be what you’re looking for.  However, if your process generates small spherical dust then a baghouse may better suit the application.  
Air to Cloth Ratio & Static Pressure Drop A typical drum filter operates at 100:1 air to cloth ratio versus a baghouse containing 6 filters with a 10:1 air to cloth ratio.  Air to cloth ratio is the volume of air allowed per square foot of medi…
