A vibratory tray feeder is also called as a vibratory pan feeder or oscillating feeder. The main parts of this feeder is a tray that moves rapidly back and forth according to meter material into a process.
This basic vibratory movement of the tray throws each particle of the material up and forward from one point on the tray and drops down at a point farther along the tray.
In the first glimpse, this operating mode sounds too simple. But if the feeder isn’t carefully chosen for your application or if it’s not properly operated or maintained, problems can affect the feeder’s performance.
AAG Engineering Technologies can be your partner in selecting precise vibratory tray feeder ideal for your applications. We offer vibratory feeders in various modes and with varying capacities.
Today’s article will explain feeder’s components, operations and how vibratory tray feeder works. This basic information from AAG Engineering will accompany you in a long way to spot problems before they can upset your process and result in major production losses. Let us start with reviewing some vibratory tray feeder essentials.
Basics about vibratory tray feeder
As stated above, primary components in a vibratory tray feeder are the tray along with a drive unit, and a spring system between the tray and the drive unit. The tray’s receiving end is mounted under a supply hopper outlet, and the discharge end is located above receiving equipment.
In operation, material discharges from the supply hopper onto the tray. The drive unit generates vibration. This vibration is then transmitted by the spring system to the tray. Now, as mentioned earlier, the tray vibrates, particles are thrown up and forward from one point on the tray and drop down at a point farther along the tray.
The distance this drive unit moves back and forth is called the feeder’s amplitude. How high the particles are thrown compared with their forward movement is called the angle of deflection.
The number of times per minute this action is repeated is the feeder’s frequency. The drive unit can be linked to a controller that increases or decreases the tray amplitude to adjust the feed rate.
More about the vibratory tray
The tray is also called as pan or trough. These trays can have several shapes like flat, curved, V-shaped, or tubular and can be almost of any length or width to suit your application needs.
Moreover, at AAG we also construct this trays with various materials so that it can suit your material’s characteristics.
A stainless steel tray, for instance, is more suitable to handle difficult solids like abrasion-resistant steel, polyethylene, epoxy, rubber, or another material with difficult characteristics.
It is crucial that to function properly tray’s center of gravity must be mounted slightly above the drive unit’s driveline that is, the centerline of the unit’s housing or casting. Any alterations to the tray after the feeder is installed will likely change the location of the tray’s center of gravity and alter the feeder’s performance.
That is why, it is essential that before mounting a vibratory tray feeder, you should consult a professional help to ensure unobstructed working in your plant. AAG Engineering Technologies can be your professional guide with its decades of experience in bulk material handling system.
We have rich experience in serving application where controlled feeding of material is required in industries such as steel, fertilizer, cement, glass and more.
We are one stop solution for all your bulk material handling system solutions!!
