How To Select The Right Electromagnetic Vibratory Feeder

When dealing with small or fine materials in your manufacturing facility you know how difficult it can be sometimes to move the materials from one location to the next. These are probably too small for most roller-based conveyor belts, and due to the size it might stick to a traditional conveyor, which can lead to problems with the machine. Having someone on hand to push the materials down is a waste of manpower, not to mention an expensive, inefficient way to go about moving these materials. Instead, your best option is to opt for an electromagnetic vibratory feeder. 

These vibratory feeders help move fine materials, which will either stick, smear, corrode, or otherwise cause damage to other equipment. Vibratory feeders are used in all kinds of industries, ranging from automotive to food, and pharmaceuticals. Because the equipment is used by so many industries there are a number of electromagnetic vibratory feeder systems available. You want a system that will move your material and yet not damage it, so here is a guide on how to select the right electromagnetic vibratory feeder.

How To Select The Right Electromagnetic Vibratory Feeder?

Before we delve into how to select the right electromagnetic vibratory feeder, let’s first explain you what exactly electromagnetic vibratory feeder is:

What To Know About An Electromagnetic Vibratory Feeder

There are three basic feeder systems that are similar in design and functionality, but, depending on your current setup and production location, you will want to go with one over the others. The electromagnetic vibratory feeder uses variable intensity vibrations, which you can fix at a vibrations per minute strength. The exact vibrations per minute you need will hinge on what you’re moving. While this is an excellent option for most materials, as it uses a single phase power source, it is not ideal if your production facility has varying temperature shifts (such as if you don’t have a functioning, or reliable HVAC system). It also won’t handle hazardous materials. An electromagnetic vibratory feeder is especially sensitive to voltage fluctuations as well. If you have a steady temperature within the building and are not in a hot weather location (that doesn’t rely on air conditioning), the electromagnetic vibratory feeder method is likely best for you.

The second option is known as electromechanical. This system uses twin electric vibrations. This gives you some more fluctuation in your vibrations intensity. These kinds of setups are able to handle both hazardous materials and working in hazardous conditions. It is also able to handle temperature shifts better than what an electromagnetic vibratory feeder can. You know the work environment you’re in so you will need to decide (although you can go over your work environment when ordering the equipment for additional insights into what works best for your facility).

Lastly, there is a feeder known as an air-powered feeder. This is another feeder that works well with hazardous materials and in hazardous conditions. The pistons are air cushioned, which helps reduce some of the impact on the hardware. It’s also easy to maintain as it doesn’t need the same kind of tuning as the other vibrating feeders. However, these feeders are not well equipped to handle heavier loads or to be used outside. You must know how to select the right electromagnetic vibratory feeder based on its qualities and features. 

Feeder Materials

There really is no limit to the size and design of the tray. If you need a specific shape for your trap to meet the specs of your production floor that shouldn’t be a problem. If you need it to turn around a corner or you need a decline in the feeder tray that isn’t an issue either. What you do need to consider though is the materials of the feeder.

If you’re working with any kind of liquid (or item that might leak) you will want to consider a neoprene, urethane, or other removable coating. This allows you to easily clean the feeder tray should something leak. It also protects the tray to prevent corrosion in the event of a leak that goes unnoticed. On the other hand, you can opt for stainless steel when you are moving heavier duty materials and you need something that can handle what you are moving through the production floor.

Spring Systems

The springs used in your electromagnetic vibratory feeder are necessary as it helps the vibrations move from the drive to the tray. However, there are different spring systems based on the materials you’re moving. A fiberglass spring system is the most popular option as it is perfect for lighter conveyor systems. These are also less expensive. However, the springs are not able to handle heavier equipment. If you need a heavy duty setup you’ll want to consider steel coils. Steel is used for both heavy duty and high temperature setups (such as up to 300 degrees, typically). Steel does cost more but it can withstand more stress.

There is also a rubber spring and air mount spring system. Rubber spring is fine and can be used with heavy duty setups, although the operating temperature must remain under 120 degrees, otherwise the rubber will crack, split, and fall apart. Air springs reduce noise and are perfect for extremely heavy duty conveyors, such as those used in mining. Because there are no springs it will not be corroded with dust.

Custom Tray Clamps

Perhaps you work with materials that will leave some residue and needs to be cleaned regularly. Stopping production to hose down your feeder and then let it dry is time consuming. However, you can opt for a custom tray clamp design. Some designs offer a quick release feature, so you can quickly remove the trays without the use of any tools. With this feature you can place a new, removable coating on top while the removed coating is cleaned. This makes cleaning your electromagnetic vibratory feeder while maintaining production far easier.

Finding The Right Electromagnetic Vibratory Feeder

There are a number of feeder options, one of which is perfect for your manufacturing setup. Ultimately it comes down to not only the production floor configuration of your facility, but also what you are moving and the temperatures which it will be operating at. These tips will help you how to select the right electromagnetic vibratory feeder.
