Features and Strengths
of SWECO Vibratory Mills

Ultrafine Grinding
to the Submicron Range
and Sharp
Particle Size Distribution

SWECO’s vibratory mill enables fine grinding to the submicron range by combining its unique high-frequency vibration and cylindrical media. Because SWECO’s vibratory mills can tightly control particle size distribution, they are particularly effective for processing materials that require strict particle size uniformity, such as ceramics, pharmaceuticals, and high-quality pigments.

Reduced Contamination
and Lower Maintenance Costs

When operated in low-energy mode, the mill reduces impact on the media and lining, thereby reducing product contamination caused by wear. Additionally, because the mill has fewer moving parts and uses highly wear-resistant, replaceable linings, such as elastomers and ceramics, it can significantly reduce maintenance frequency and costs.

Maintenance Features
of SWECO Vibratory Mills

Compared with conventional ball mills, SWECO’s vibratory mill transmits less vibration to the installation foundation and does not require special foundation work. The internal lining can be selected from materials such as wear-resistant polyurethane and ceramic, and the design allows easy replacement.

For Companies Looking for
a Precision Vibratory Mill
for Difficult-to-Grind
Materials

SWECO’s vibratory mills deliver high-efficiency, low-contamination fine grinding through the company’s unique vibration technology. It is particularly effective in pharmaceuticals and electronic materials, where avoiding contamination is crucial, and in ceramics, where control of particle size distribution is important.

CHECK
Find the Right Vibratory Mill
for Your Material

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.

3 Recommended Vibratory Mills
by Grinding Goal

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.

Grinding Capabilities

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.

Maintenance

When bearing replacement is required, the vibrator unit can be swapped with a spare, allowing operation to resume quickly with minimal downtime.

Pot Volume

Grinding Capabilities

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.

Maintenance Support

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.

Pot Volume
High-amplitude: 9.5–510.9 gal (36–1,934 L); low-amplitude: 0.7–845.4 gal (2.7–3,200 L)
Media
Cylindrical grinding media; media available from SWECO
Lining
Abrasion-resistant metal, ceramic, or elastomer
