Vibratory Dryer Introduction

Vibratory finishing is a wet process by default.

So, you should invest in a dryer to completely dry your workpieces.

That’s where a vibratory dryer comes into play.

There is often a wide channel that allows you to pour the finished parts into the dryer chamber.

Once the dryer has done its job, it’s time for you to separate the workpieces and the finishing media.

But it doesn’t have to be your job. The inlet sizes found on the vibratory tumblers are totally customizable.

There is an extended separation sieve as well that ensures all of the media are separated from the parts.


Product Description

Corn cob media is the most commonly used material to clean the parts.

The heating element under the dryer is responsible for warming up the corn cob and then it absorbs water from any parts’ surface.

It can also clean the media residue from the workpiece for a better and more polished look.

Inovatec has batch and continuous feed vibratory dryers for you.

Both of these types are very easy to operate and can be easily attached to the vibratory finishing machine itself.

Vibratory Dryer FAQ Guide

1. What is a vibratory dryer machine?

Because of the wet nature of vibratory finishing, it is important to heat and dry the workpieces after the finishing processing.

Vibratory dryer machines help in drying wet metal and non-metal workpieces/components after the finishing and cleaning process.

They are especially used to speed up the drying process for finished workpieces that must not oxidize.

They usually come in forms that can be integrated with vibratory finishing machines very easily.

This helps in guaranteeing a compact but complete industrial finishing framework.

2. How do vibratory dryer machines work?

In most vibratory dryer machines, workpiece drying takes place through warming up the loaded media.

This process involves loading the workpiece(s), media, and compound.

After loading, the machine is then turned on, with the machine separating the loaded workpieces almost immediately.

The media – usually maize or corn cob – is warmed up. They are then deployed to rub on the workpiece, absorbing the water in the process.

In some other types of vibratory dryer machines, the process is a bit different.

This type uses a vibratory conveyor over which either a gas-fired infra-red or electrical manifold, or any other hot air steam, gas, etc., is molded.

As the material passes under the heated manifold, it is also continuously rolled through vibration.

This helps in turning the material over and over for even or equal drying across all sides and crevices.

The hot workpieces are then passed on into an insulated maturing holding bin where they are cooled.


3. What are the important components and compartments of a vibratory dryer machine?

The Machine

This refers to the interconnected hardware or machine parts that make up the vibratory dryer machine itself.

Some of its most important constituents are:

Process chamber or work bowl:

This is the often-enclosed compartment where media, water, and workpieces are loaded and rotated at an operator-specified rate for drying.

Their insides are usually lined with polyurethane to cushion the workpiece-barrel impact as they come in vigorous contact, helping to extend the lifespan of the barrel.

This is the part of the machine that supplies the mechanical power needed to spin and rotate the barrel for drying.

In other vibratory dryer machines too, it supplies the heat energy necessary to warm up the media or to directly dry the wet workpiece.

ZDHG600A vibratory dryer

Control system:

Like all other industrial machines, vibratory dryer machines have systems through which temperature, electricity input, speed, efficiency, etc., are monitored and controlled. Such a control panel may be stand-alone or included on the frame of the machine.

A stable vibratory dryer machine base through proper arrangement of the springs enhances the stability of the machine while it is running without the need to perhaps bolt it to the floor.

Dust Extractor:

In maize/corn cob applications, this is necessary for the collection of fine dust resulting from the process.

4. What are the factors to consider in choosing a vibratory dryer machine?

The following are some of the factors to pay utmost attention to when choosing a vibratory dryer machine:

Drying or cooling process:

Like it was earlier mentioned, vibratory dryer machines use different methods for drying workpieces.

It’s left to you to decide the method you prefer – either on the basis of operational cost or purchase cost.

ZDHG600 vibratory dryer


Not every vibratory machine is built to carefully handle very fragile parts.

So, this makes it very important to know the type of workpiece that a vibratory dryer machine can dry or cool.

It is better for the marketer, vendor, or manufacturer to know the capability of the drying machine.

Space requirements:

It’s equally important to consider the size of the machine in order to have an informed guess of how much space it would likely take away from your available industrial space.

Overall Design:

Vibratory dryer machines come with varying specifications, designs, and capabilities.

This makes personal preference a non-negotiable factor in making a machine choice.

So, you should consider a machine with an overall design that you can cope with.

Safety and Compliance Standard:

No matter the manufacturer of a vibratory dryer machine, certain minimum energy, safety standards need to be met.

Look out for these standards that are determined by relevant governmental agencies.


This is a very important factor to consider when choosing a vibratory dryer machine because the machine’s carrying capacity at a go determines the duration within which numerous workpieces would be dried.

Barrel carrying capacity thus varies considerably from machine to machine, as well as from manufacturer to manufacturer.

Drainage system:

Vibratory dryer machines – just like all other mass finishing machines – have drainage systems through which extracted moisture and residues from workpieces are flushed out of the machine.

Check this out in the machine.

Energy and Noise: 

Vibratory dryer machines are notably loud and noisy when in operation.

There are however new-generation models that make less noise due to the inclusion of noise-suppressing parts.

Your budget would determine your choice.

5. What are the things to bear in mind when using a vibratory dryer machine?

Post-drying machine maintenance

After a successful drying of parts in a vibratory dryer machine, the machine needs to be cared for through rinsing using freshwater.

Doing this to the machine after every use helps to prevent contamination, rusting, or malfunctioning in subsequent drying processing.

Keeping an eye on Barrel Load

The combined height of both workpiece and media should not be any less than 45% or go higher than 60% of the process chamber’s capacity.

This is to prevent the churning out of poorly dried workpieces because, as the load height increases, the drying action suffers a slowdown.

The optimal media-to-workpiece ratio is 3:1, although the ratio for large or fragile workpieces may go as high as 6:1.

Proper choice of media

There are technicality and skill involved in making a choice of drying media.

This is because some media are built to successfully and appropriately carry out drying more than some others.

For example, corn cob is the most popular choice when it comes to choosing drying media because of its relative suitability to absorb moisture very well.

Besides, you need to choose the right corn cob media size. So that the corn cob does not get stuck in the holes and recesses of the part.

6. What are the functionalities of vibratory dryer machines?


Vibratory dryer machines help purify workpieces from stains.

Such stain or dirt may include dust, greases, or other residues stuck on the workpiece.

These may have been gotten from previous processing or human transportation.


Importantly, vibratory dryer machines help to take away moisture and water from wet workpieces to prevent factory-developed rusting.

7. What materials are vibratory dryers well-suited for?

In terms of application, vibratory dryer machines are well-suited for drying all sorts, types, and classifications of metal and non-metal workpieces after the mass finishing and cleaning process.

Its usage of special corn cob and walnut shell as media, and/or together with the effect of hot air, makes it a versatile machine that is usable on almost all workpieces, parts, or components that one can ever think of.

8. What are the available types of vibratory dryer machines?

There are two types:

  • Single lap continuous processing vibratory dryer machine:

These are computerized or automatic vibratory dryer machines can process and dry workpieces without operator input.

Because of their computerized nature, these types of dryer machines are put on standby as a part of a mass finishing manufacturing network of machines.

This means that such a machine can immediately start drying the wet workpieces after the previous polishing process by another machine has been done.

  • Batch processing vibratory dryer machine:

These are drying machines that require operator input in the loading of the mass –including workpieces, media, and/or compound.

This type of machine can only dry the batch of workpieces that are loaded in them from time to time.

9. Do media play any role in the operation of vibratory dryer machines?

Yes, definitely.

For vibratory dryer machines that use special types of media to dry up wet workpieces, the absence of the media makes drying impossible.

The wet workpieces would in such a situation just be rolling in the processing chamber without something to dry them.

10. What parts are dried in a vibratory dryer machine vs what parts are dried in a centrifugal spin dryer machine?

Because of the force with which centrifugal spin dryers dry workpieces, they aren’t so suitable with fragile workpieces.

Vibratory dryer machines, on the other hand, make use of soft media to dry parts.

This makes them suitable for both fragile and non-fragile workpieces.

11. What is the difference between a vibratory dryer and a centrifugal spin dryer?

The difference lies in the type of drying force or methodology.

Vibratory dryer machines use soft media like corn cob to transfer heat from the machine to the workpiece.

Centrifugal spin dryer machines, on the other hand, use centrifugal force to directly extract moist from parts.

That is, the force throws the workpiece around, particulate the moist outward to the inside of the processing chamber.

The moisture then accumulates at the bottom of the bowl to be drained away.

12. How can the long-lasting usage of a vibratory dryer be guaranteed?

To get the most out of a barrel finishing machine, it’s necessary to do some regular checkings and maintenance of its components.

The best thing to do first is adhering to the manufacturers’ maintenance recommendations.

This is because vibratory dryer machines differ from one another, requiring different maintenance processes.

Ensure to check through, understand, and implement the manufacturer’s maintenance recommendations.

Some other general maintenance tips include:

Ensuring the machine is in good condition before usage:

It’s important to habitually check for internal and exterior damages in the barrel tumbling machine for metal parts before use.

Doing this helps safeguard the workplace from preventable accidents, including spillings, outbursts, and so on.

These include the following:

1.Checking regularly for the sensitivity and good health of the electric control system

2. Examining the process chamber by opening the lid and turning the eccentric body with the hand, to make sure it rotates freely without hindrance.

In addition, let the vibratory dryer machine run idly to see if it runs smoothly without any strange noises.

If you notice any strange noise, sound, or hindrance, turn off the machine and take steps to troubleshoot the machine.

Such manufacturer-encouraged troubleshooting could include lubrication of parts of the dryer machine, replacement of the bearings, and such other steps included in the owner’s manual.

If it all proves abortive, seek the services of a professional.

3.During operation, pay attention to and regularly examine the loose screw bolts, particularly those that secure the vibratory motor.

If there are any screw bolts found loose, screw them in time.

When screwing the bolts, see to it that the flange of the motor is parallel to the flange of the screw vessel.

If not, the two flanges cannot be screwed evenly and the bolts would run loose easily.

This could lead to loud noises, bolt cutting, or perhaps serious accident of damage to the screw vessel and the motor.

4.Lubricant with an industry or manufacturer-specified quality or composition must be used to ensure the smooth running of moving parts in the machine.

13. How can a vibratory dryer machine be appropriately operated and used?

First, the wet workpiece and media are loaded into the processing chamber of the machine.

Second, the operator adjusts the controls on the control panel, including stuff such as temperature and motor speed.

Lastly, once the vibratory machine completes the drying process, power off the heating elements, stop the vibratory bowl, and turn the on-off knob into the off position.
