No need to worry about finding a compatible trough for your vibrator—these feeders come ready to use. With no mechanical parts to wear out or lubricate, downtime is rare. These feeders use electromagnets to shake material down the trough, making them ideal for moving substances that could cake or stick. For example, they’re often used to transfer powders into mixing tanks and add binders to foundry sand for metal casting. Compared to most vibrators, these feeders are quiet, too. At around 50 dBA, they generate about the same amount of noise as normal conversation.

Required Vibrator Controllers—Adjust throughput from a steady stream to a trickle. If you want to synchronize multiple feeders to run at the same speed, you can connect them to the same controller as long as the total current draw is less than 5 amps. With a durable polycarbonate housing, these controllers won’t dent or crack from occasional bumps. They’re also rated NEMA 4X for protection from dust, dirt, and washdowns.

Solve flow problems at construction sites and other locations without electricity or an air supply. These vibrators are often used to shake sand, gravel, and other small particles in drums and spreaders. They have wire leads to connect a 12-volt battery (sold separately). Motor is totally enclosed fan cooled (TEFC) for use in environments with splashing water and dust. Every 10 pounds of dry material requires one pound of force to move it. If your bin has 200 pounds of dry material, you need a vibrator with at least 20 pounds of force.

Spinning motion aggressively deburrs and polishes your parts. These tumblers are quieter than vibrating and centrifugal tumblers but take longer to complete a finishing cycle—typically several days. They also may round sharp edges as they deburr.

Fill the tumbler to a maximum of 60% capacity to finish multiple parts at the same time. Run the tumbler wet or dry, then unload the mixture into a sieve to separate your parts.

Finish parts in minutes instead of hours or days. Also known as centrifugal disc finishers, these tumblers use a high-speed rotating disc to create centrifugal force. The force drives parts and media into a spiral motion for quick finishing and prevents parts from sticking together. These tumblers also preserve the shape of your parts better than rotary tumblers, which may round sharp edges as they deburr them.

These tumblers are small enough to fit on your benchtop. Fill them with media up to two-thirds capacity and run wet to finish multiple parts at once. A dosing pump regulates the amount of cleaner that drips into the bowl during tumbling. When the cycle is complete, tip the tilting bowl to unload the mixture into a sieve to separate your parts.

The finest finish of any polisher we offer. These polishers use high-frequency vibrations to remove microscopic surface imperfections that are too small to see with the human eye. They’re ideal when you need a perfectly smooth, flawless surface in the smallest features, such as ribs and slots in molds and dies. When you adjust the stroke length, these polishers automatically adjust the vibration frequency. To reduce the risk of damaging your workpiece, they generate little heat and automatically shut off when you press too hard against your workpiece.

Use these polishers with ceramic polishing stones and diamond files. Attach the polishing stone or file to the handpiece using a compatible tool holder.
