Features and Strengths
of MURAKAMI SEIKI MFG. Vibratory Mills

High-Energy Vibration
for Fine to
Ultrafine Grinding

MURAKAMI SEIKI MFG.’s vibratory mill is a high-energy grinding machine that applies vibration motor technology. Its structure applies strong impact and grinding force to the media and raw materials, enabling processing in the fine to ultrafine range for materials such as fine ceramics, battery materials, and metal powders.

It supports both dry and wet processes and allows process design according to raw material characteristics and target particle size. Its sealed structure also helps suppress dust dispersion and ensure workplace safety.

Scale Design Supporting
a Consistent Path from R&D
to Mass Production

Another feature is that the same series ranges from small “Vibro pot” units for testing to batch-type models for small-lot, multi-product production and continuous models for high-volume processing. Even when processing volume and operating mode differ, the common design philosophy for media and lining material selection, as well as the basic structure, creates a configuration that makes it easy to study conditions for scale-up.

Because this equipment lineup allows transition to mass-production machines based on grinding conditions established at the research stage, it is well suited for applications requiring stable quality, such as new material development and battery and electronic materials.
