MicroGrinding Systems, Inc. is a U.S. company that manufactures and sells the VibroKinetic Energy Mill (VKE mill) using its proprietary vibrational energy technology.
This article reviews and explains the features, product specifications, and examples of materials that can be processed by vibratory mills from MicroGrinding Systems.
MicroGrinding Systems’ VKE mill uses a design in which the grinding chamber is fully suspended by radially arranged springs. In addition to the energy supplied by the vibratory motor, it uses the rebound energy of the tuned spring system to improve grinding efficiency.
This enables energy savings compared with ball mills.
The VKE mill supports both dry and wet grinding and allows a wide range of particle size adjustment, from coarse grinding to submicron ultrafine grinding. In dry grinding, combining the mill with an optional air classification system allows efficient recovery of fine powder while preventing over-grinding and achieving the desired particle size distribution.
Even high-hardness minerals and metal ores can be processed in a short time through high-speed, powerful impact force.
| Process Type | Dry / Wet |
|---|---|
| Operation Mode | Continuous / Batch |
| Examples of Materials Processed | Various minerals and hard materials |
| Typical Applications | Ultrafine grinding, liberation and concentration of valuable metals, waste recycling, and nanoparticle production |
| Applicable Industries | Mining, chemicals, the ceramics industry, and the recycling industry |
| Test Machine | Available Please contact the manufacturer regarding costs (if a machine is purchased within six months of testing, the test fee will be fully deducted from the purchase price)* |
Because the vibratory motor is the only major moving part, the VKE mill has no complex drive system components, making maintenance easy. Wear parts are limited to the grinding media and liners, and replacement intervals depend on the abrasiveness of the material being ground. Its design allows quick motor replacement, helping reduce downtime and offering strong maintenance benefits.
No grinding examples using vibratory mills were listed on the official website.
MicroGrinding Systems’ VKE mill combines high energy efficiency with powerful grinding capability through its unique vibration mechanism. The VKE mill is a strong option for achieving fine grinding while keeping operating costs low. The VKE mill supports both wet and dry processing and integrates smoothly with classifiers, making it suitable for a wide range of manufacturing lines.
The right vibratory mill varies depending on the material, such as metals, ceramics, LFP raw materials, and industrial waste.
This article reviews the specifications of vibratory mills for mass production and their industry-specific applications. It explains and compares vibratory mills suited to different materials based on differences in structure, vibration method, and processing capacity. Please refer to this article when selecting the right grinding machine.
This standard production model grinds hard materials from a 1/4-inch feed size to fine powder. Equipped with a 9 hp motor, it offers processing capacity comparable to conventional 60 hp ball mills while enabling finer grinding.

Even with the same material, the right vibratory mill depends on what you need to achieve: fine grinding hard materials at high purity, making the particle size distribution uniform from the grinding stage, or recycling hard-to-process waste. Below are three manufacturers, each matched to a different grinding goal.
Its proprietary low-frequency, high-amplitude design generates high-G impact force, reducing difficult-to-grind materials such as SiC to submicron sizes in a short time. Material-contact parts can be made metal-free, supporting mass production of high-purity electronic materials.
When bearing replacement is required, the vibrator unit can be swapped with a spare, allowing operation to resume quickly with minimal downtime.
SWECO's proprietary Vibro-Energy motion densely packs cylindrical media to maximize contact between media surfaces. This makes it easier to precisely control particle size and distribution, so particle size can be made uniform at the grinding stage.
Few moving parts help keep maintenance costs low, and abrasion-resistant linings can be replaced. SWECO also supplies grinding mill parts and accessories, including media and linings, to support ongoing maintenance.
Its eccentric design positions the exciter away from the center of gravity, generating strong impact forces and frictional heat. It can recycle scrap such as cemented-carbide drills and process asbestos into fiber-free raw material.
For easier maintenance, the main drive components are located outside the grinding cylinder, reducing the work required for inspections and parts replacement.
