Features and Strengths
of ALPA Vibratory Mills

Improved Productivity
Through
a Space-Saving Design
and Grinding Efficiency

ALPA’s vibratory mill features a space-saving design that delivers grinding capacity comparable to a ball mill while requiring only a small installation footprint. It enables micron-size grinding of a wide range of soft and hard materials with a Mohs hardness of 9 or lower. A key feature is that the mill can control particle size by adjusting the grinding media and amplitude.

High-Purity Fine Grinding
Through Reduced
Contamination Risk

ALPA’s vibratory mill has a structure in which the grinding media inside the cylinder generate collisions and friction through high-frequency vibration. By using wear-resistant materials such as high-manganese steel and high-chromium steel for the grinding media and lining plates, the mill can reduce contamination risk caused by wear and achieve low-contamination grinding.

For Companies Seeking
High-Efficiency
Fine Grinding
of Hard Materials
in Limited Space

ALPA’s vibratory mill is equipment that enables high-efficiency fine grinding of hard materials while making effective use of limited factory space. Automatic control reduces the monitoring burden on operators and contributes to building a stable mass-production system for high-quality powders.

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
17.2–803.2 gal (65–3,040 L)
Media
Steel, stainless steel, alumina, nylon
Lining
Steel, stainless steel, alumina, zirconia, rubber (polyurethane, NBR), nylon

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
Process Type
High-amplitude: Dry / Wet; low-amplitude: Wet
