Case Studies

Overview

Bead Mills are used in many manufacturing processes to reduce material particles to a specific micron size.

Milling (or wet grinding) is an aggressive process involving the agitation of small metal or glass beads in a chamber to mechanically break down media that is often very viscous and has a tendency to set if temperature and flow are not controlled or the mill is not cleaned out properly between batches.

Consequently, specially designed mechanical seals are required incorporating:

• A double seal configuration
• An inboard ‘rotating seat’ to prevent hang up and clogging
• Wetted parts made from materials resistant to abrasion and chemical attack
• An independent seal support system
• Control of sealant pressure, temperature and flow

 

 

Working with end users and service partners over many years, NASH has developed a high quality, responsive service for most makes, types and sizes of mechanical seals fitted to bead mills supplied by all the leading manufacturers including:

• Netzsch Mastermix
• Buhler
• Drais
• Eiger Torrance
• Dyno-Mill (Willy Bachofen)
• Knight
• FrymaKoruma
